## What reviewers found

### iRobot Roomba 105 Vac + AutoEmpty Dock

- Vacuum Wars (1.41 Vacuum Wars stars): Removed 82% of embedded sand, above the 75% average, but picked up only 29% of flattened pet hair and 79% of long hair wrapped the brush. Coverage was about 630 sq ft per charge and it has no obstacle avoidance. [Source](https://vacuumwars.com/roomba-105-vac-review-irobots-cheapest-self-emptying-robot-vacuum-in-2025/)
- RTINGS: Named the Roomba 105 its best cheap robot vacuum for smart navigation, long battery life and an optional self empty dock, but called vacuuming only adequate and obstacle avoidance weak. [Source](https://www.rtings.com/robot-vacuum/reviews/best/budget)

### 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)
