Roomba and Shark have swapped strengths, and most comparisons haven’t caught up.
Short version: buy the Shark to vacuum, buy the Roomba to mop. That sounds glib, but it’s what the independent testing shows, and the two machines currently sit within about fifty dollars of each other. You’re not choosing between a premium option and a budget one. You’re choosing which job you want done properly.
This comparison leans on measured results from Vacuum Wars, Homes & Gardens and TechRadar rather than manufacturer claims, because the manufacturer claims have stopped being useful. iRobot doesn’t publish a suction figure in pascals any more. It quotes multiples of a discontinued 2015 model instead, which tells you nothing you can compare against a rival.
If you’re still deciding whether a robot is worth it at all, we’ve looked at whether robotic vacuums earn their keep separately.
Roomba vs Shark: which should you buy?
Buy the Shark PowerDetect UV Reveal if you want the better vacuum. Buy the Roomba Max 705 if you want the better mop. Neither machine does both well.
That holds at current pricing, where the two sit close enough that cost isn’t the deciding factor. It would change if iRobot’s new range tests well, and I’ll come back to why that’s still open.
Here’s the evidence, all from Vacuum Wars’ standard test suite:
| Measured | Shark UV Reveal | Category average |
|---|---|---|
| Deep carpet cleaning | 88% | 78% |
| Pet hair pickup | 91.5% | 82% |
| Obstacle avoidance | 20 of 24 objects | 16 of 24 |
| Coverage per charge | 2,093 sq ft | 1,170 sq ft |
| Combined mopping | 0.55 | 22.5 |
| Overall rating | 3.80 / 5 | 2.58 / 5 |
Look at that mopping row again. It isn’t a typo.
What changed in 2026
iRobot replaced its entire robot vacuum range in July 2026, and most of the models still being recommended online have been discontinued.
The j-series, i-series and s-series are gone. In their place: Roomba Plus 415, Plus 515, Plus 575, Max 715 and Max 775, plus a non-robot floor cleaner called the Electro Plus. Six products, announced on 7 July 2026.
So if you’re reading a comparison that recommends a j7+ or a Combo j9+, it’s out of date. Those aren’t sold new by iRobot any more. Stock still shows up on Amazon, but when I checked the Combo j9+ the only offer was a single used unit from Amazon Resale, listed with cosmetic damage to the casing and moderate packaging damage. That’s not a product any more. That’s the last one in the warehouse.
Shark has done nothing so dramatic. Its PowerDetect line has grown steadily and the UV Reveal sits at the top of it.
Here’s how the new Roomba range lines up, since almost nobody has written it down yet:
| Model | Tier | What it adds |
|---|---|---|
| Roomba Max 775 Combo | Flagship | ClearView Pro LiDAR, PrecisionVision AI, heated PowerSpin roller mop |
| Roomba Max 715 Vac | Premium, vacuum only | Same navigation, no mop, AutoEmpty dock |
| Roomba Plus 575 Combo | Upper midrange | Dual-line LiDAR, PrecisionVision AI, 46% smaller body |
| Roomba Plus 515 Combo | Midrange | Dual-line LiDAR, DualClean pads, longest runtime of the range |
| Roomba Plus 415 Combo | Entry | Dual-line LiDAR, the cheapest model with obstacle AI fitted |
The important line in that table is the last one. On the outgoing range you had to spend heavily before you got obstacle detection at all, which is how a mid-priced model ended up scoring zero out of 24. Making it standard from the entry model up is the right fix. Whether it works is a separate question.
What are they like to live with?
Both machines are close to hands-off for weeks at a time, but they ask for different things when they do need you.
The Shark’s NeverTouch Pro base empties, refills and washes the mop pad itself, and Shark rates the debris bag at 60 days. The Roomba’s AutoWash dock does the same jobs and iRobot rates it at 75 days of emptying, plus around eight weeks of mopping at one run a week. In practice both mean you deal with the machine roughly once every two months.
The consumables differ in a way that matters over a few years. Both use disposable debris bags, which is an ongoing cost, and both use brush rolls and filters that need replacing. The Shark’s mop pad is antimicrobial and designed not to be changed often. The Roomba’s roller gets washed and heat-dried in the dock after every run, which is a large part of why its mopping stays effective.
Height is the other practical difference. The Shark stands 4.1 inches tall, which sounds trivial until it won’t fit under your sofa. Slimmer flagships from Roborock and Dreame get down to around 3.1 inches, and if low furniture is where your dust actually collects, neither machine here is the right answer.
Noise is fine on both. Neither is quiet enough to sit next to while you work, and both are quiet enough to run while you’re in another room.
How do they compare on cleaning?
The Shark cleans carpet better, by a margin wide enough to matter.
Vacuum Wars measured 88% deep carpet debris removal on the UV Reveal, ten points clear of the category average. Independent testing of the Roomba Max 705 put it at 65 to 69% pickup on low-pile carpet using cereal and coffee grounds, which is under par for a machine at this price.
On hard floors it’s closer. Both handle large debris well, and Homes & Gardens rated the Max 705 strong at picking up the bigger stuff that defeats cheaper robots.
The Shark also runs much further between charges. It covered 2,093 sq ft on a single charge against a 1,170 sq ft average, with battery efficiency of 2.7 minutes per 1% against a 1.6 norm. On a large open-plan floor that’s the difference between finishing in one run and coming back for a second.
How do they compare on navigation and obstacles?
Shark wins on obstacle avoidance, and the outgoing Roomba range was genuinely poor at it.
The UV Reveal avoided 20 of 24 objects on the standard course against a 16 average, using spinning LiDAR alongside RGB sensors and a camera Shark calls UltraRange.
The outgoing Roomba Plus 405 Combo scored zero out of 24. Not a low score, zero. It carries no obstacle sensors at all, so it drives into things and hopes for the best. That model is still listed on Amazon at roughly half its original price, and it’s the one I’d steer you away from hardest.
The Max 705 does better, because it has PrecisionVision AI and recognises cords, socks and pet waste. Homes & Gardens hit the opposite problem in a month of testing: detection is oversensitive, and it stops for things it could comfortably drive over. Irritating rather than harmful, but you’ll notice it daily.
For the underlying detail on how these systems differ, see how robot vacuums navigate.
Mopping: where iRobot still wins
The Roomba Max 705 has the best robot mopping system in this comparison, and the Shark has one of the worst ever tested.
Homes & Gardens ran the Max 705 for a month in a house with children and pets and called its heated PowerSpin roller “one of the best mopping systems around”, describing the result as close to a deep manual clean. The roller turns at 200 RPM, the AutoWash dock washes and heat-dries it afterwards, and you never handle a bucket.
The Shark goes the other way, badly. A combined mopping score of 0.55 against a 22.5 average is the worst part of an otherwise excellent machine. It leaves up to five times the usual water on the floor, and testers recorded floors still damp more than half an hour later. On sealed hardwood that isn’t just inconvenient, it’s a risk you don’t want to take twice a week.
If mopping is the reason you’re buying a robot, the decision is already made.
Pet hair: where iRobot loses
Shark picked up 91.5% of flattened pet hair. The current entry-level Roomba managed 29%.
That 29% belongs to the Roomba 105 Vac, which also wrapped 79% of a seven-inch hair sample around its brush roll against a 38% average. The Max 705 does better than its cheaper sibling, but “disappointing pet hair suction” is the phrase Homes & Gardens landed on, and it’s fair.
Shark isn’t flawless here either. Anti-tangle is merely average at 29% wrap, so long hair still needs clearing off the brush now and then. Even so, 91.5% against 29% isn’t a close call.
Pet owners should start with the Shark, or look at how Eufy compares against Roomba for a cheaper option.
Which is better value?
Both are selling well below list, for different reasons.
The Roomba Max 705 is discounted because it’s been superseded. The Max 775 replaced it three weeks ago. That’s a real saving on a capable machine, but you’re buying the outgoing model, and long-term support is a fair question given iRobot went through Chapter 11 in December 2025 and now operates as a subsidiary of Picea Robotics.
The Shark discount is ordinary retail promotion on a current model. Much less of a warning sign.
Worth saying plainly: a steep discount on a robot vacuum usually means a replacement has arrived or is about to. When you spot a model at half price, find out what replaced it before you decide you’ve found a bargain. It’s the same lesson Neato owners learned the hard way.
The verdict, and what would change it
On current tested evidence Shark is the better buy for most people, because vacuuming is what a robot vacuum is mainly for and the Shark does it considerably better.
Buy the Roomba Max 705 instead if you have mostly hard floors, mopping is the point, and pet hair isn’t your daily battle. That’s a real use case, and the Max 705 serves it better than anything Shark currently makes.
To put it in concrete terms:
- Carpeted house, dog or cat: Shark, without hesitation. The 91.5% pet hair figure against 29% from the current budget Roomba is the whole argument.
- Tiled or hardwood throughout, no pets: Roomba Max 705. You’ll get a genuinely clean floor rather than a damp one.
- Big open-plan space: Shark. Covering 2,093 sq ft on a charge against 1,170 average means one run instead of two.
- Mixed floors and you want one machine to do everything: neither, honestly. The Dreame L60 Ultra PE is the obvious starting point instead. It removed 94% of deep carpet debris in Vacuum Wars testing, picked up 100% of flattened pet hair with no brush wrap at all, and mops without soaking the floor. Its own weakness is that the headline 30,000 Pa suction figure doesn’t survive measurement, but it does both jobs competently rather than one brilliantly. There’s more of the field in our best robot vacuums roundup.
- Low furniture you actually need cleaned under: neither. Both are 4.1 inches tall.
That fourth point is worth dwelling on. Robot vacuum marketing has spent five years insisting these machines are all-rounders, and the test data keeps saying otherwise. Shark and iRobot have each built something that does one job very well. Picking the right one starts with being honest about which job you need.
What would change this verdict is iRobot’s new range. LiDAR and PrecisionVision AI are standard from the Plus 415 upwards, which addresses exactly the failure that made the outgoing models score so badly. If that holds up under testing, the recommendation moves. But no independent reviewer has measured any of the six new models yet. Every Max 775 video online is either an iRobot marketing clip or a short demo from a Japanese rental company.
I’m not recommending an untested machine on the strength of a press release. When Vacuum Wars or RTINGS publish numbers, this page gets updated.

Head-to-Head Comparison
Detailed Reviews
Shark PowerDetect UV Reveal 2-in-1 Robot Vacuum and Mop
Better vacuumThe best-vacuuming robot Shark has made, and one of the strongest vacuums at any price, paired with a mop that genuinely doesn't work. Buy it to vacuum and ignore the mop, or buy something else if wet cleaning matters.
What We Like
- Vacuuming is genuinely class-leading. Vacuum Wars measured 88% deep carpet cleaning against a 78% average and 91.5% pet hair pickup against 82%, and rated it 3.80 overall where the category averages 2.58
- Avoided 20 of 24 objects on the obstacle course, well clear of the 16 average, using NeuroNav AI with RGB sensors and an UltraRange camera
- Covers 2,093 sq ft per charge against a 1,170 average, on a 180-minute runtime. Big open-plan homes are its natural habitat
- Battery efficiency measured 2.7 minutes per 1% charge, well ahead of the 1.6 category norm
- Dried-on stain removal scored 183 against a 94 average, so it does shift stuck-on mess when it gets to it
What We Don't
- The mopping is the problem, and it is a serious one on a machine sold as a 2-in-1. Combined mopping scored 0.55 against a 22.5 average, leaving up to five times the usual water behind and floors wet for 30 minutes or more
- TechRadar's verdict was "impressive hardware laid to waste by software issues", and Vacuum Wars separately called the app basic and limited
- 4.1-inch height blocks it from the low furniture that slimmer flagships clear
- Threshold climbing tops out around 25mm, which is short of rivals that manage 40mm and more
- Anti-tangle is only average at 29% hair wrap, so long hair still needs occasional attention
iRobot Roomba Max 705 Combo Robot Vacuum and Mop
Better mopA specialist rather than an all-rounder. Buy it if you want the best robot mopping available and can live with mediocre pet-hair pickup, because that trade is the whole product. At the clearance price it makes sense; at list it never did.
What We Like
- The heated PowerSpin roller mop is the reason to buy it. Homes & Gardens called it "one of the best mopping systems around" and the closest a robot has come to a deep manual clean
- AutoWash dock washes and heat-dries the roller itself, so there is no rinsing and no bucket
- Handles large debris well on hard floors and tested strongly on carpet
- Quiet in use, with reliable ClearView Pro LiDAR navigation and 9-minute mapping of a 1,000 sq ft floor
- 75 days of auto-emptying and roughly 8 weeks of mopping between dock refills
What We Don't
- Pet hair is its weak point, which matters on a vacuum at this price. Reviewers consistently report disappointing pet-hair pickup, and independent testing put low-pile carpet pickup at 65-69%
- Reliability is the recurring complaint. It has been described as the most error-prone Roomba reviewed, and the most detailed YouTube test on it was conducted across three replacement units
- Bulky enough that it struggles with tight spaces and low furniture
- Obstacle detection errs on the oversensitive side, stopping for things it could clear
- Superseded by the Max 775 in July 2026, and discounted well below list as a result, which is the value case and the warning in the same sentence
Dreame L60 Ultra PE Robot Vacuum and Mop
Better at bothNeither Shark nor iRobot does both jobs well. If you want one machine that does, this is where to start looking.
What We Like
- Carpet deep cleaning hit 94% in Vacuum Wars testing, among the highest results they have published
- 100% pickup on the flattened pet-hair test with 0% wrap on the DuoBrush in the 7-inch hair test
- Avoided 21 of 24 objects on the obstacle course using an AI camera, 3D ToF and LED, with 220 recognised object types
- Dual mop pads at 13N pressure with 212°F (100°C) hot-water self-cleaning, and a dock that washes, dries, refills and empties
- Coverage per charge measured at roughly 1,202 sq ft, above the category average
What We Don't
- The headline 30,000 Pa doesn't translate: measured suction scored 0.57 against a 0.99 category average, and airflow 15 against 17
- Threshold climbing is oversold. Dreame claims 40mm tiered, but testing cleared 19mm and failed at 25mm
- Battery efficiency is below average at 1.49 minutes per 1% charge despite the 240-minute claim
- 250ml onboard dustbin is small, so pet-heavy homes will see frequent dock returns

Frequently Asked Questions
- Is Shark or Roomba better in 2026?
- Shark is the better vacuum and Roomba is the better mop. In Vacuum Wars testing the Shark PowerDetect UV Reveal removed 88% of deep carpet debris and 91.5% of pet hair, against category averages of 78% and 82%. The Roomba Max 705 was described by Homes & Gardens as having one of the best robot mopping systems available, but reviewers consistently call its pet hair pickup disappointing. Neither machine does both jobs well, and they currently sit at similar prices.
- Why did all the old Roomba models disappear?
- iRobot replaced its entire range in July 2026. The j-series, i-series and s-series are all gone, replaced by a new naming scheme running from the Roomba Plus 415 up to the Max 775. If you are looking at a j7+, j9+ or i3 EVO, those are discontinued, and stock that remains tends to be used units or third-party resellers charging well above the original price.
- Does the Shark PowerDetect UV Reveal mop properly?
- No. Vacuum Wars gave it a combined mopping score of 0.55 against a category average of 22.5, because it leaves up to five times the usual amount of water behind. Floors stayed wet for more than 30 minutes. Treat it as an excellent vacuum with a mop attached rather than a genuine two-in-one.
- Is the new Roomba range any good?
- Nobody knows yet. The six models iRobot launched in July 2026 have not been independently tested by Vacuum Wars, RTINGS or any major publication. On paper the new range addresses the biggest weakness of the outgoing one, since LiDAR and PrecisionVision AI are now standard from the Plus 415 upwards, and the outgoing Plus 405 scored zero out of 24 on obstacle avoidance because it carries no obstacle sensors at all. That improvement is still a claim, not a measurement.
- Which brand handles pet hair better?
- Shark, and it isn't close. The PowerDetect UV Reveal picked up 91.5% of flattened pet hair in Vacuum Wars testing, against an 82% category average. The outgoing Roomba 105 Vac managed 29% on the same test and wrapped 79% of a seven-inch hair sample around its brush roll. Pet owners looking at current models should start with Shark.
