Congratulations you've struck gold!

You've stumbled upon the most thorough, detailed and informative vacuum buying guide on the internet! 

If you're looking for a definitive resource on how to buy a vacuum cleaner then you can find everything you will ever need to know in this article. 

First things first. If you haven't already, we recommend you start by reading our previous article, What is the Best Vacuum Cleaner Type for Me?

This will help you decide what type of vacuum you need and will cause you to consider:

  • The types of flooring in your home;
  • The number of levels in your home. For instance, having stairs in your home may lead you to decide a canister is your preference;
  • The size of your home;
  • The storage space available for storing a vacuum cleaner;
  • Your personal fitness, strength and mobility. If you have a bad back and want to avoid bending over for instance you might choose to go for an upright as opposed to a canister.
  • Is this your main vacuum or supplementary? You may be looking to supplement the upright with something more handy for quick clean ups and vacuuming the car.

Considering these will help you narrow down the choice between the main styles of vacuum:

Now grab yourself a coffee and set aside 10 minutes to read through this Ultimate Vacuum Buying Guide before going shopping!

Our guide provides detailed advice on vacuum cleaner design, the features and accessories, performance, life span and warranty.

Vacuum Buying Guide - Primary Considerations

The decisions that you make on the following key aspects of a vacuum cleaner’s design as well as your budget will have a major influence on the model and brand of vacuum that you choose.

By deciding which vacuum cleaner features are important to you and how much you want to spend you will be able to easily find a model that is a perfect fit.

Cost & Value for Money

Whether the price of a vacuum cleaner is a primary purchase consideration will vary depending on the household, however for some it will be a major factor.

As the saying goes, “you get what you pay for” we are often led to believe that you cannot buy good quality without paying a high price. This is often not the case with vacuum cleaners and price doesn't necessarily reflect quality.

Vacuum cleaners range in price hugely these days from as little as $30 to over $1000 and it is possible to find good quality at the lower end of the scale with lots of features.

What's the Best Vacuum under ?$

It's important to have a budget in mind before you go vacuum cleaner shopping. For the budget conscious we've selected and reviewed our top choices within the lower price range of vacuum cleaners in these articles:

Prioritising your health

On the other hand if price is less of an issue than other requirements such as having a vacuum that is best for reducing allergy and asthma symptoms in the home then by paying more you can get the best Certified Sealed HEPA filtration system.

Furthermore, it is often good value for money in the long run if you spend more upfront and put that money to good use by upgrading attributes such as build quality, durability and warranty.

Bagged or bagless vacuum cleaner?

BAGGED Vacuums

vacuum buying guide

Simply put, bagged vacuums have a dust-bag inside the main compartment which captures the dust and dirt as you clean. Air travels directly from the suction hose straight through the bag, through the motor and filters and out through the exhaust of the machine.

Ongoing Costs of replacement bags

Depending on the type of bag you use it can either be thrown away when full or emptied and replaced. Either way there is an ongoing cost of replacement bags for bagged units, which needs to be considered and the best bags don’t come cheap.

Performance Considerations

The quality of the bags make a difference to the performance of the vacuum cleaner. Modern, good quality bagged machines have anti-clog bags, which reduce the risk of the bag being clogged with dirt and thereby reducing the suction power of your cleaner. 

Cheaper bags will clog when they become full and suction will reduce. The bags are providing filtration of the air exhausted back into the house and therefore the quality of the filtration is linked to the quality of the bag. 

Miele and SEBO vacuums are widely renowned as the best quality bagged cleaners money can buy and their bags all contain several finely graduated layers of filtration. Filtration within the bag can also reduce smells that are returned to the air through the exhaust.

Emptying is More Hygenic

Supporters of bagged cleaners argue that they are more hygenic and allergy friendly than their bagless counterparts. This is based on the argument that there is more risk of dust being released into the air when emptying a bagless vacuum, which is a problem if you have allergies to dust.

The best dust bags provide automatic closing once removed from the vacuum so that no dust escapes.

Noise Considerations 

Bagged vacuums also tend to be quieter than baggless units, although this again comes down to the particular model you are looking at but it is worth keeping in mind. 

So to summarise the pros and cons of bagged vacuums:


  • Easy, allergy friendly emptying
  • Filtration in stages, through the bag and then through the machine filters, which can mean more allergens are captured and prevented from being released back into the home
  • Can be quieter than bagless depending on model


  • Lesser quality units can lose suction as the bags fill
  • Ongoing costs of replacement bags as well as filters
  • Can be difficult to know when the bag is full unless there is an indicator light

Bagless Vacuums

A Dyson Vacuum Review An Overview of 3 of the Brand’s Latest Models

There are two types of bagless vacuum cleaner - filtered and cyclonic.

  • Filtered bagless vacuum cleaners rely on a filter located within the dust canister to trap the dirt. 
  • Cyclonic bagless vacuum cleaners use the power of cyclonic action to separate the dirt from the air and trap it in the canister without the use of a filter. 

Cyclonic bagless vacuums are generally more efficient and provide superior performance than filtered bagless vacuums. A well-designed cyclonic filtration system does not lose suction power due to airflow restriction, until the collection vessel is almost full.

Once you understand how a bagless vacuum works it is easy to see the benefits they can bring.

If you're considering a bagless cleaner be sure to take a look at the ones we've compiled in our Best Bagless Vacuum Reviews.


  • no ongoing costs of bag replacement
  • more environmentally friendly due to no throw away bags
  • Filters are often washable
  • Dust bins are usually clear allowing you to observe when they are full
  • Easy disposal


  • Dust may escape into the air during emptying, exposing you to allergens
  • Bagless models can be noisier
  • filters still need to be cleaned or replaced regularly on most models


vacuum buying guide

So by now you know that the quality of the dust bag has a large part to play in terms of a vacuum's filtration performance. Filtration is important as dust particles in the air can cause major allergic and respiratory reactions as well as being a vehicle for the spread of airborne disease.

You've likely heard of the regular allergens such as dust mites, pollen and animal dander and mold spores. This article provides some tips on dealing with these common allergens.

If you have pets you will want a vacuum cleaner that is both good at picking up pet hair and also filtering out animal dander. Check out our Best Vacuum Cleaner for Pet Hair Reviews for some good options.

You also want your filtration system to deal with the less well known semi-volatile organic compounds (SVOCs), such as:




polycyclic aromatic


hydrocarbons (PAHs)

polychlorinated buphenyls


These are silent contaminants that are released from materials found in the home and ride on the dust in the air you see and breathe.

  • SVOCs are dangerous because they have no odor and can continue to build up in the home for years because of their continual, slow emission rate from sources. 
  • SVOCs can be particularly harmful for those who suffer from chronic illnesses or immune diseases, however they will put stress on anyone’s immune system.

The good news is that regular use of a vacuum cleaner with a good (specifically, HEPA) filtration system can reduce SVOCs as well as other allergens in the home.

The type of filter used and design of the filtration system is a key element in how effective the vacuum cleaner will be at removing these threats and the wrong choice could actually exacerbate allergy symptoms and asthma.

Many modern vacuums are now designed with two or more filters: a primary and secondary. When purchasing new filters they may come as a kit: 

  • The primary filter captures the bulk of the dirt that is sucked in by the cleaner before it is exhausted into the atmosphere. 
  • A secondary filter if present will capture any remaining microscopic particles. 

The most common types of filters are as follows:

Cartridge Filters

Cartridge filters may either be a primary or secondary filter and are usually disposable but can be cleaned a few times before they need replacing by simply tapping them to release the dust that has collected in the grooves.

They are commonly a circular shaped plastic or rubber housing containing the cartridge medium such as pleated paper or polyester and are easy to remove and install.

Foam Filters

These are a secondary filter and often machine washable. It is handy to have a spare that can be used immediately whilst the dirty one is being washed and dried.

Cloth Filters

These filters are less common in domestic vacuums and usually found in heavier duty commercial and industrial cleaners. They are a washable and long lasting type of filter.

Disc Filters

Disc filters look similar to coffee filters and are less common than the other types. They can be made from either paper, which are disposable or cloth, which are usually washable. 

HEPA (High Efficiency Particulate Air) Filters

We highlighted the merits of HEPA filtration on vacuum cleaners in our recent article here. These filters are ideal if you have allergies or asthma.

This is because they must remove 99.97 per cent of particles that are 0.3 micrometers or larger in size in order to qualify to the HEPA standards.

It’s important to ensure that the filters are genuine HEPA filters though and not “HEPA-like” or “HEPA-type”.

Genuine HEPA filters must achieve the standard set by the US Dept of Energy (or in Europe EN 1822) to receive the HEPA designation and have to be independently tested to assess their ability to stop dust egress.

The HEPA filter should be located in the vacuum cleaner "post motor" so as to ensure the air that is finally exhausted from the vacuum cleaner is allergen free.

If the HEPA filter is to do its job successfully it is also crucial that the vacuum cleaner is a a "Certified Sealed" system (also called an abatement level vacuum), which ensures through the use of rubber gaskets that no particulates leak out at junctures where the bag, motor, hoses and nozzles connect.

Only Certified Sealed HEPA vacuums (such as those made by Dyson and Shark) are completely air-tight. This means all air sucked through the machine passes through the filter and none escapes back into the air, providing the best filtration results possible.

Carbon-Charcoal Filters

If you have pets and are concerned about pet smells in your home then a carbon filter would be a good choice.

The Miele C3 Complete Cat & Dog, reviewed here is an example of a Certified Sealed System, with a carbon filter in lieu of a HEPA filter (other models are available in the Miele canister range that provide HEPA certified sealed systems).

As an alternative to the HEPA filter this filter still provides excellent particle retention of over 99.9% down to 0.5 microns. A carbon filter provides better performance with filtration of animal smells than a HEPA filter and so may be a better choice for animal lovers that do not have severe allergies!


Micro-Fresh filters are filters that have been treated with non-hazardous chemicals that act to sterilise the air and remove bacteria and fungi spores.

ULPA Filters

ULPA stands for Ultra Low Penetration Air and these filters are commonly found in vacuum cleaners used in the healthcare industry.

They are a disposable, extended-medium, dry-type filter in a rigid frame, having a minimum particle-collection efficiency of 99.999% for particles in the size range of 0.1 to 0.2 microns.

Regular domestic vacuum cleaners do not usually contain these filters but as this is the Ultimate Vacuum Buying Guide we have included them for completeness! Moving on....

Suction Power

vacuum buying guide
  • So how does a 12amp vacuum cleaner compare with a 1200watt vacuum cleaner?

Everyone wants the most powerful vacuum cleaner they can afford, right? 

Power is a big marketing play by vacuum manufacturers and most vacuum cleaner specifications provide a power rating of some sort. This can be a confusing area when comparing vacuum cleaner performance as manufacturers don’t always quote the same units of measurement.

All too often the numbers quoted can be misleading as to the overall performance of the cleaner as they do not tell the full story. Specifications can include watts, amps, volts, horsepower, air watts, and airflow.

Lets look briefly at the operation of the vacuum cleaner to help understand these specifications:

  • In all vacuum cleaners the airflow from the cleaning head or tool to the bag or bin and then out through the exhaust is created by the vacuum motor.
  • When the fan(s) inside the vacuum motor spin, a partial vacuum is created and the pressure inside the vacuum cleaner drops below the ambient (or existing) air pressure in the room.
  • This causes air outside the vacuum cleaner to be sucked through the vacuum cleaner taking all of the dirt and nasties with it.
  • To put it simply, the more powerful the motor, the greater the pressure differential and therefore the more suction and airflow. This is why most vacuum cleaner specifications provide information that relates either directly or indirectly to the motor.

Here is where the confusion starts. Specifications for components such as the motor do not necessarily relate to the performance of the entire vacuum cleaner, and therefore are only part of the story.

The next few sections of this Ultimate Vacuum Buying Guide will provide a detailed insight into the common ways that manufacturers specify the power of the vacuum cleaner:

Watts or Amps?

The input power of the vacuum motor is measured in watts, which is a valid way to evaluate and compare the power of the motor.

Specifications also commonly rate vacuum cleaners in amps, which refers to the maximum amount of electrical current used by all of the electrical components when operating.

The drawback with these ratings is that a vacuum cleaner’s wattage or amperage rating doesn't take into account the efficiency of the motor, the number of fans (two is not necessarily better than one) or the overall vacuum cleaner design.

The performance of the vacuum in terms of suction power is down to much more than the power of the motor and so you shouldn’t read too much into these figures.

Comparing Watts and Amps

Amperage ratings cannot be directly compared with wattage ratings. This can make it hard to compare across brands.

However it is possible to convert amps to watts using the formula, amps x volts (120 in the US and Canada and 220-240 in the UK, Europe and Australia) = watts. By reversing this formula to watts/volts = amps, you can also convert watts to amps.

Hot Tip: make your life easy by using the online calculator in the link above.

By converting the units this will give a better indication of how differently rated vacuums compare. However, it is not an exact comparison of “apples with apples"!

Vacuum cleaner specifications given in watts will only account for the power from the motor.

Amperage ratings use the total electrical consumption of the vacuum cleaner including other power usage within the cleaner. This can include any secondary motors that might power the power nozzle, any headlights or indicator lights or display panels that are on the unit, etc.

If you are comparing a vacuum cleaner rated in amps with one in watts you will therefore need to account for the additional power usage for these items.

Worked Example

A vacuum cleaner rated as 12 amps that has a motorised power nozzle (which typically use 1.5 amps) is likely comparable to a vacuum cleaner rated as 1200 watts (1200/120 =10 amps).

By subtracting the amperage of the power nozzle from the total rating of 12 amps (12-1.5=10.5 amps) this allows a more direct comparison with a vacuum cleaner’s specification that is given in watts and you have converted to amps.

We can therefore better compare the rating of 10.5 amps for the motor and any lights compared to the 1200W converted rating of 10amps for just the motor.

If the amperage on the vacuum cleaner specification is given only for the motor you will not have to make this allowance and it will allow a direct comparison with another cleaner’s wattage (once converted).

Sealed Suction (Water Lift)

Another useful specification to look for in a vacuum cleaner is the sealed suction, which is measured in inches of water lift.

  • A measurement of how many inches the motor will vertically lift a 1" column of water is taken when the motor is completely sealed. 
  • This rating shows how much power the vacuum has to lift debris from the floor surface, which is then removed to the dust bag via airflow.

The greater the rating, the better the ability to pick up debris such as sand and other soils from flooring.

Water lift ratings also test the vacuum cleaner performance under air resistance from items within the vacuum such as loaded filters and filled dust bags.

On canister vacuum cleaners a water lift of at least 90 inches is recommended. Upright vacuum cleaners generally do not provide water lift specifications.

Air Watts

As we have outlined above, typical vacuum power specifications such as watts and amps measure the vacuum cleaner's input power

In recent years some vacuum cleaner manufacturers have attempted to rate the output power of their products, which is measured in units called air watts.

Air watts are also commonly specified for central vacuum systems. The airwatt calculation takes into account air flow and suction and therefore gives an indication as to the efficiency of the motor.

The formula used to compute air wattage differs between vacuum cleaner manufacturers. The standard airwatt formula comes from ASTM International (ASTM F558 - 13), who are the leading provider of vacuum cleaner testing protocols (for further information on vacuum cleaner standards and testing refer to our detailed article here).

The problem with specifications for air watts as with those outlined above for watts, amps and water lift is that unless specifically stated otherwise they only relate to power from the motor.

This will only give an indication to the potential performance of the vacuum cleaner. These numbers will mean nothing if the vacuum cleaner as a whole is not well designed.

It is more important to understand what amount of suction and/or air flow is actually being delivered at the hose or down on the floor and this air flow is not the same as and should not be confused with air watts.


The airflow of a vacuum cleaner is the main thing you want to know. If all vacuum cleaner specifications provided an airflow rating, life would be much simpler and it would be a straightforward task to compare the cleaning ability across different models!

However, although an airflow rating is the best quantifiable measurement of the cleaning ability of a vacuum cleaner, it is not as common to see these provided by manufacturers as it is to see ratings in amps or watts.

Airflow is usually measured in cubic feet per minute (CFM) and denotes the force of the airflow across a surface that picks up the dirt and moves it to the dust bag or container. Therefore, the more airflow, the better the cleaning ability of the vacuum cleaner.

Airflow is an excellent specification because it takes into account both the power of the vacuum motor, which creates suction, as well as the resistance of the bag and filter system that this air must pass through. This is the most important specification to look for when choosing a vacuum cleaner.

Airflow is generally measured through the vacuum cleaner without hose or attachments connected. The figure will not usually show how the airflow is affected by the hose and wands, or where the cleaning tool meets the floor or other surface, as well as how the cleaner is affected by the bag filling with dirt and filter loading.

On canister vacuum cleaners airflow of 100 CFM or more is recommended. Only certain models of upright vacuum cleaners will provide airflow ratings (by-pass motor types) and a CFM of at least 60 is recommended.

Weight, Comfort and Maneuverability

Woman having fun vacuum cleaning with ease


The weight of a vacuum cleaner is closely related to what type of cleaner it is. Uprights are generally the heaviest units and stick vacuums are the lightest models. When determining the best vacuum cleaner type that is right for you, weight should therefore be one of the factors in your decision.

However, there are a wide range of weights available for each vacuum cleaner type. So don't worry, if you think you need an upright but are concerned about weight you can still get something fairly light.

If weight is an important factor for you then take a look at our best lightweight vacuum reviews - 5 of your top options. Very lightweight units are a popular secondary cleaner in many homes or even as a main cleaner in smaller homes.

Maneuverability/ Handling Comfort

Another factor to consider along with weight is the overall comfort and maneuverability of the unit.

Take a good look at the handles on the unit and the design of the wheels:

  • are the handles comfortable? 
  • do the wheels look like they will provide a solid support that will last whilst providing a smooth, full 360 degree movement across a variety of floor types?

Canisters generally offer the best maneuverability, however some upright models are now very flexible, e.g. the Shark navigator which features a head that lies flat so you can get underneath couches or beds.

Some cleaners are very easy to move around but some can get stuck and don't swivel easily. This is where it's good to take a look at user feedback for the cleaner that you are considering.

Likewise, some handles fit nicely into the hand and have a soft, padded comfort grip and there are models that include controls such as suction power adjustment right on the handle for convenience.

If the vacuum is easy to move around and feels comfortable to use you are more likely to use it frequently and it will be a pleasure to use, versus one that feels like hard work and puts you off ever getting it out of the cupboard.

Corded or Cordless?

Cordless Vacuum in a clean room

You need to decide if you want a cordless vacuum cleaner or one with a cable. This decision as well as the length of the cable affect the vacuum's maneuverability.

Vacuum cleaner technology is improving all the time and there are some superbly powerful cordless vacuums available in the market right now.

A cordless vacuum provides ultimate flexibility and convenience of use.

If you're home is not too large then the battery runtimes available now are good enough for this to be your main cleaner.

Check out our best cordless vacuum reviews for 5 top choices to consider. Dyson lead the cordless vacuum market with their Dyson V-Series Cordless Vacuums.

If you have a large home then you would be better served with a corded vacuum. Most vacuums these days come with retractable cords but the length of the cord varies quite a lot so be sure to check the specification for this.

Many vacuum specifications will provide the cord length and the flexible hose length, which will give you a total cleaning radius.

You can use this information to determine if the vacuum is suitable, which will depend on the size of your home.

The largest cleaning radius that you will see is around 36ft (10.973m), which you get with the Miele C3 canister models but most modern vacuums will provide at least 30ft (9.144m). 


Cleaning Tools and Attachments

vacuum buying guide

The main type of cleaning tool on the cleaner needs to be selected based on your needs, which relates to the type of flooring to be cleaned and whether the home has pets. If you have pets then this should be a key factor in your choice of vacuum cleaner - check out our Best Vacuum Cleaner for Pet Hair Reviews for some good choices.

For homes with a lot of carpet and particularly deeper pile carpet, you really need a special carpet vacuum cleaner with a brush roll as they do a better job of dislodging soils from carpets than suction alone.

Brush Rolls

All uprights have brush rolls, however if you are looking at canisters for cleaning deep pile carpets and have pets, consider a “powerhead” or “power nozzle”. These brush rolls are driven by an additional motor, which gives it extra power to reach deep into the carpet pile to remove the dirt.

“Turbo heads” on canisters are not as powerful as a “power head” as they are purely air driven; that is the brush roll is powered by the airflow created by the canister's suction motor.

This type of canister is a good choice when there is not a large percentage of carpet in the home or its is lower pile with only moderate (no pet hair).

When looking at brush rolls, one thing to consider is the specific type of carpet that you have as this can influence the type of brush roll to choose. Some brush rolls contain beater bars, some brushes are extra stiff and some are softer.

Deep pile, low density carpets such as shags and friezes for instance can require a softer brush roll. In addition, a vacuum with a manually adjustable cleaning height is a good choice if you have extensive deep pile carpets.

Brush Roll Height Adjustment

Many vacuums advertised with "auto adjusting pile height" do not actually adjust in height and simply slide across the carpet via a skid plate. This relies on the density of the carpet itself to determine the lift setting, which is not a good solution.

These vacuums do not know the actual length of the carpet yarns and vacuum the carpet at a "one size fits all" height. This can lead to excessive brushing of longer yarns and your carpet fuzzes out on the tips as a result. This relates to the height setting of the roller/brush.

One of the functions of the beater bar element of a brush roll is to fluff loose any trapped yarns that are down in the carpet under other yarns. A beater bar will vibrate these yarns loose and allow the vacuum to pull them back up.

Brush Roll On/ Off Function

Some vacuum cleaners also have the ability to turn off the brush roll and go into suction only mode, which can be useful if you have very delicate carpets that you don't want to agitate with a brush.

Some really high pile length carpets are special cases and can only be cleaned properly if you just use air suction only and no roller/brush or beater bar action at all.

If you're relying on suction alone though for high pile carpets then you may need to rake for trapped yarns every so often! If this is you, look for a manually adjustable height brush roll with an on/off switch to turn it off so you have a choice of how best to clean and protect your high pile carpets.

For vacuum cleaners with brush rolls that are specifically designed to care for your carpets we have taken advice from the Carpet & Rug Institute for advice. They actually certify vacuum cleaners that take the best care of carpets and we used this to select our favourite vacuums for different carpet types.

Flexible Hoses & Telescopic Wands

The length of the flexible hose on canisters is an important specification, but this is also worth checking on uprights as well. Also consider the telescopic wand that comes with the unit as together with the hose these tools are key to determining the ease in which you can reach high places, furniture and floors. 

Look for overall cleaning radius in the vacuum specification, which will confirm how far you can reach with the hose and wand with the power cable fully extended. A good reach for a vacuum cleaner’s cable, hose and wand would be at least 30ft (9m).

Wand Attachment Tools

Aside from the main cleaning head on a vacuum, it is useful to have other secondary cleaning tools for cleaning furniture, ceiling corners and other hard to reach places. Options for these vary depending on the type of vacuum cleaner that you have decided on. There will be a set of tools that come with any vacuum cleaner as standard and some models sell additional tool attachments separately if required.

Canisters generally have a better selection of tools than other types of cleaner, although the best modern uprights will also offer a good selection of tools to attach to their hoses.

  • One thing to watch for is whether all of the tools attach directly to the base of the vacuum! If they don't you can guarantee you will forget to take them around the house with you and never have them ready to use when you need them!

Some on-board tool caddies are better than others as well so look for feedback about attachments falling off easily as this could be a frustration you want to avoid. If a good selection of tool attachments are important to you, a canister or upright is the way to go as cordless unit will not provide as many (or often any).


vacuum buying guide

It is possible to get very quiet powerful vacuum cleaners, which can make the cleaning process much nicer and if this the case you will be likely to pull it out more often. To reduce noise to a minimum vacuum cleaners need special insulating materials and better made motors and fans. The quietest mains powered cleaners are usually bagged canisters and the loudest are bagless uprights.

  • Bagless vacs are usually noisier because the motor is closer to the case of the product!

The dust bags in bagged units can be designed to contain sounds by making use of innovative technologies that provide acoustic insulation, usually as well as better filtration!

The more powerful the motors in a vacuum the more noise that will be produced and it is the design of the vacuum that determines how well this noise is dampened. A cheap vacuum cleaner will have much less attention to detail in this regard and will be much noisier as a result.

When checking vacuum cleaner specifications if you see a noise rating less than 70dB this would be a fairly quiet cleaner and anything 65dB or less could be considered about as quiet as you can get without compromising on power.

Battery operated cordless vacuums are generally quieter than mains powered units due to their lower power and lighter construction. As a result they could be a good option if you want a really light, quiet handy cleaner. 


By Capacity we mean dust bag or dirt bin capacity.

Capacity can be an important consideration for some people and particularly for those with large homes.

Uprights generally have a greater capacity of their dust bags or bins than other cleaners. However Miele canisters also have very large capacities.

If you don't want to be emptying the dust bin every time you vacuum then you need to factor in capacity to your decision making.

One of the benefits offered by Miele canisters for instance is a dust bag of around 1.2 gallons (C1 & C3 canisters), which is double the size of most normal canisters and even a lot of uprights.

Cordless vacuums usually have the smallest capacity. However, the exception to the rule is the Dyson Outsize cordless vacuum, which has a dirt bin capacity more than double most of the other cordless models on the market.

The capacity of your vacuum cleaner also has a role in terms of maintaining suction performance. Cleaners with larger dust bags will have better airflow, and therefore, cleaning ability. This is especially true as the dust bag fills and smaller bags can quickly become clogged and lose suction.


Checking out the warranty details for a vacuum cleaner can give you an insight into it’s durability and reliability.

Many manufacturers offer a long warranty period just for the motor and a shorter period for all other parts so it's important to check what exactly is covered.

Standard warranty period for a vacuum cleaner is 12 months, however the higher end vacuum cleaner manufacturers generally offer much longer.

  • Miele offer up to 7-year warranty and their cleaners are built to last 20+years; 
  • Dyson offers 5-years on the majority of their models.

When thinking about or researching warranty it's also good to know or get feedback on the manufacturers customer service support. This will alert you to how easy or difficult it may be to source a replacement or repair if things go wrong and you ever need to call on the warranty.

Also watch out for vacuum cleaners that have the Good Housekeeping Seal of Approval, since this provides for 2 years warranty direct from the Good Housekeeping Institute, which may be better than that offered by the manufacturer themselves!


Last but not least in our vacuum buying guide is a brief run-down on the additional features that are offered on different models of cleaner. Some are standard and you should be getting without paying anymore whilst others sit more toward the luxury category and not available on cheaper cleaners as well as entry models of higher end cleaners.

Bag full indicator - fairly standard on bagged machines, although not all have them so worth checking for. Not usually found on bagless machines as you can just look through the clear dirt bin!

Auto rewind cable - standard on canisters, not so on uprights, although many do have this excellent time saving feature.

Air Volume Adjustment – standard on most canisters but not all uprights, this is a really necessary feature if you intend to use your accessory tools without sucking up the curtains.

Manual Height Adjustment – as mentioned above, this is a useful and perhaps essential function if you have very deep pile carpets. This is different from automatic height adjustment, which aids in the transition between different floor types, which is useful but doesn't allow any form of control.

Headlight - this festure is standard on all upright vacuum cleaners, positioned right on the front of the cleaning head and allows you to see and catch that dirt in those dark corners of the room.

Edge Cleaner - This is a common feature found on a lot of cleaners and is really useful so it's worth checking for. It helps you to pick up all dirt from the area surrounding the cleaning head and so can save you the time for having to go back down the sides of walls with a different accessory tool.

Hard Floor Options - Multi-floor cleaners usually have some sort of feature to allow for the different operation required between cleaning carpets and hard floors. This might be an on/off switch for the brush roll or a hard floor setting switch.
