The Roomba Combo 10 Max is iRobot’s flagship vacuum-and-mop robot, pairing the brand’s decades-refined obstacle avoidance with a self-cleaning AutoWash dock and a clever auto-retracting mop arm. On paper it’s the most complete Roomba ever made. In expert testing, though, it’s a mixed bag: excellent vacuuming and pet-hair pickup, underwhelming mopping, and navigation that feels a generation behind LiDAR rivals.
Note: iRobot went through Chapter 11 bankruptcy in late 2025 and was acquired by Picea Robotics in early 2026. Roombas remain on sale with working app support today, but long-term support is less certain than with other brands.
We haven’t physically tested this machine. This is a research-driven review based on manufacturer specifications, expert reviews (Tom’s Guide, Vacuum Wars, TechRadar, Android Authority), and verified owner feedback. Where a spec isn’t published, we say so — and iRobot notably publishes no Pa suction figure, so you’ll see “not published” below rather than an invented number.

Vacuuming: the strong suit
The Combo 10 Max’s best-reviewed trait is vacuuming. Tom’s Guide measured overall cleaning performance of 95.5 and a pet-hair score of 97.5 — genuinely excellent numbers. Vacuum Wars likewise praised its deep-cleaning and vacuuming performance. The dual multi-surface rubber brushes resist hair tangles well, and the Dirt Detective feature learns your home’s habits to prioritize dirtier rooms and adjust suction.
The caveat: iRobot publishes no Pa suction figure, so direct suction comparisons with Roborock or Dreame flagships aren’t possible on specs alone. Tom’s Guide did note the brush design can push some debris around, and the robot struggles more with larger debris and thicker carpets than LiDAR rivals with disclosed high-Pa suction.

Mopping: the weak link
This is where expert opinion turns. Tom’s Guide called the mopping “not very effective”; Vacuum Wars labeled the whole mopping system “underwhelming.” The hardware concept is genuinely clever — SmartScrub moves the mop back and forth with downward pressure to mimic hand mopping, and the auto-retract arm lifts the mop pad to the top of the robot when crossing carpet, keeping rugs completely dry. But in testing, rivals with spinning pads, vibrating pads, or roller mops clean measurably better.

Navigation: camera-only in a LiDAR world
The Combo 10 Max uses PrecisionVision — camera-based vSLAM with AI object recognition for pet waste, cords, socks, and shoes. iRobot backs this with its P.O.O.P. (Pet Owner Official Promise): if the robot fails to avoid solid pet waste, the company replaces it. That’s real confidence in obstacle avoidance, and it’s iRobot’s signature strength.
The trade-off, and every expert reviewer noted it: camera navigation maps more slowly and clumsily than LiDAR, bumps into things more often, and performs poorly on dark or reflective surfaces. Android Authority described a “roll over every spot” approach relying heavily on physical bump sensors. In 2026, when even mid-range rivals ship LiDAR, this feels dated. Our robot vacuum buying guide explains the LiDAR-vs-camera divide in detail.
The AutoWash dock
The AutoWash dock is genuinely full-featured: it auto-empties debris into a sealed bag rated for up to 60 days, refills the robot’s water tank, washes and dries the mop pad, auto-refills cleaning solution, and runs a dock self-cleaning cycle. Vacuum Wars flagged it as louder than average and messy when washing the mop pad, but the capability checklist is complete.
App and ownership context
The iRobot Home app gets consistent praise for polish — room labels, schedules, routines, and keep-out zones are all straightforward, if less customizable than Roborock’s app. It works with Alexa, Google Assistant, and Siri Shortcuts, though not Apple HomeKit.
The elephant in the room: iRobot’s ownership. After the Chapter 11 filing and Picea Robotics acquisition, iRobot says it expects no disruption to products, the app, or support — and Roombas remain on sale with working app support today. But it’s reasonable to factor the uncertainty into a purchase decision, especially for a flagship-priced machine. We cover this in more depth in Roborock vs iRobot.
Pros and cons
- Pros: Excellent vacuuming and pet-hair pickup in expert testing (Tom’s Guide 97.5 pet-hair score); Dirt Detective adaptive cleaning; auto-retracting mop arm keeps carpets fully dry; full-featured AutoWash dock (60-day bag, mop wash/dry, water refill); polished, approachable app; P.O.O.P. pet-waste avoidance guarantee
- Cons: Mopping underwhelms versus spinning-pad and roller-mop rivals; camera-only navigation is slow, clumsy, and weak in dark rooms; no published Pa suction figure; loud dock and robot; 120-minute battery is modest for the class; premium price with weak value scores (TechRadar value 2.5/5); iRobot’s post-bankruptcy support outlook is uncertain
Maintenance and running costs
The AutoWash dock’s sealed bag is rated for up to 60 days, so bag changes are a few-times-a-year chore. The bigger ongoing consideration is the mop system: the dock washes and dries the pad automatically, but mop pads are consumables that need periodic replacement, and Vacuum Wars noted the dock can be messy when washing — expect to wipe down the wash area occasionally. As with any iRobot product, check current parts availability; the post-acquisition parts pipeline is one of the things worth watching under Picea ownership.
Who should buy the Combo 10 Max — and who should skip it
Buy it if you: are an iRobot loyalist who values the obstacle-avoidance guarantee and the polished app, mainly need excellent vacuuming and pet-hair pickup, or find it at a deep sale price that closes the value gap with LiDAR rivals.
Skip it if you: prioritize mopping performance (spinning-pad and roller-mop rivals clean measurably better), want fast LiDAR mapping, or are uneasy about iRobot’s post-bankruptcy support outlook — Roborock and Dreame flagships offer clearer long-term trajectories.

Frequently asked questions
Is the Roomba Combo 10 Max good for pet hair?
Yes — vacuuming and pet-hair pickup are its best-reviewed traits, with a 97.5 pet-hair score from Tom’s Guide and dual rubber brushes that resist tangles. For more pet-focused options, see our best robot vacuums for pet hair.
How does it compare to the Roomba Combo j9+?
The Combo j9+ is the step-down sibling: same SmartScrub mopping and auto-retract arm, but an auto-fill dock (no mop washing) and shorter battery. The 10 Max is the more complete package if you want the self-washing dock.
Should I worry about buying a Roomba after the bankruptcy?
iRobot completed its acquisition by Picea Robotics in early 2026 and says it expects no disruption to products, the app, or support. Roombas remain on sale with working app support today. The honest answer: short-term risk looks low, long-term support is less certain than with brands like Roborock or Dreame. Weigh that against the current deal you can get.
Does it work with Alexa?
Yes — Alexa and Google Assistant voice commands are supported, plus Siri Shortcuts. Apple HomeKit is not supported.
How long does the battery last?
iRobot rates it at up to 120 minutes, with recharge-and-resume for larger homes. That’s modest for the class — LiDAR rivals with 180–240 minute ratings cover more ground per charge — but the robot returns to the dock, recharges, and picks up where it left off.
The bottom line
The Roomba Combo 10 Max is a very good vacuum with a mediocre mop and dated navigation. If you’re an iRobot loyalist who mainly wants excellent pet-hair pickup, obstacle avoidance with a replacement guarantee, and a simple app — and you find it at a good sale price — it’s a defensible buy. But at flagship pricing, LiDAR rivals from Roborock and Dreame offer stronger mopping, faster mapping, and clearer long-term support for similar money.
