What reviewers found
iRobot Roomba Max 775 Combo
- Gizmodo: Good vacuuming with no clogs and a streak free roller mop that handled ketchup about as well as rivals, but noisy, a buggy app on long runs, unreliable carpet detection and trapped twice under a bed. A full vacuum and mop of 750 sq ft took about 2.5 hours. Source
- Tom's Guide: Hard to recommend. Hardwood pickup of 44% hair, 86.5% Rice Krispies and 91% chia seeds; carpet 52%, 63.5% and 35%. Bumped walls often, scattered debris with its side brushes and left slight mop residue. Source
SwitchBot K20+ Pro
- PCWorld: Tested the $748.98 Patrol Kit with a required $119.99 Hub 3: the 3K camera pans 360 degrees, but with the mobile base fitted it would not cross a slightly sloped hardwood to tile transition, and it called the vacuum decent but not a main cleaner. Source
- MacSources (80%): Rated it 80% GOOD (Design 90%, Ease of Use 80%, Price 70%); praised the modular design and under furniture reach, but noted a complex app, navigation recovery issues and camera lag. Fan accessory ran 13 to 49 hours depending on speed. Source
