## 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](https://gizmodo.com/irobot-roomba-max-775-review-a-respectable-roomba-redux-2000813995)
- 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](https://www.tomsguide.com/home/home-appliances/roomba-max-775-combo-review)
- Xataka: Excellent pet hair pickup and effective hot water roller mopping; cleaned 55 m² in 40 minutes using 33% of the battery. Fixed side brushes made corners less thorough and bags and solution are costly. [Source](https://www.xataka.com/analisis/irobot-roomba-max-775-combo-analisis-caracteristicas-precio-especificaciones)

### 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](https://www.pcworld.com/article/2924138/switchbot-k20-plus-pro-patrol-kit-review.html)
- 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](https://macsources.com/switchbot-k20-pro-review/)
