- Navigation
- dToF laser
- Mopping
- OZMO Roller 175 mm
- Runtime
- Up to 252 min silent
A former flagship that now costs about $800, with one of the best mops Vacuum Wars has tested and very strong airflow. It suits homes with lots of hard floor and pets. Skip it if you need long runtime per charge or a big onboard bin, or if fringed rugs are common in your home.

- iRobot claims 70x
- Navigation
- ClearView LiDAR
- Mopping
- DualClean spinning pads
The Plus 405 Combo gives you LiDAR mapping, lifting spin mops and a dock that empties and washes pads for about $800. Both independent tests we read were unimpressed: weak measured suction, poor carpet and pet hair results, wet floors and no obstacle avoidance. Hard floor homes that want the iRobot app can consider it on a deep sale; most buyers should compare other docks first.

What reviewers found
Ecovacs Deebot X9 Pro Omni
- Vacuum Wars: Measured 2.76 kPa suction and 27 CFM airflow, 93% pet hair pickup, 0% hair wrap, 158 of 184 on dried stains and 89% carpet deep clean. Coverage was 876 sq ft per charge against a 1,015 sq ft average. Source
- MacRumors: Three months of testing. Long hair did not tangle the brush, mopping and navigation beat the X8 Pro Omni, and Siri control through Matter worked. Thin rugs caused frequent tangles and vacuuming was loud. About 1,000 sq ft per charge. Source
- BGR (9/10): Called the roller mop the best robot mop available and vacuuming very good. Mapping was error prone and needed about 20 minutes of fixes, and tanks are no longer see through. Source
iRobot Roomba Plus 405 Combo
- Vacuum Wars (1.66 Vacuum Wars stars): Measured 0.13 kPa suction and 10 CFM airflow against 0.83 kPa and 16 CFM averages, 58% carpet deep clean against 75%, 50% flattened pet hair against 66%, and 5.20 g of water left behind. Dried stain score of 145 beat the 93 average. Called it a letdown. Source
- BestReviews: Tested in a 1,000 sq ft two level apartment. Picked up 90% to 95% of faux fur on hard floors but under 50% on carpet, spread spilled water, tangled on cords twice in one run, and the dock measured 80 to 85 dB when emptying. Testers did not recommend it. Source
