## What reviewers found

### iRobot Roomba 205 DustCompactor Combo

- TechRadar (Performance 2.5/5): Measured an average of 78 dB from five feet. The roughly 1.5 L bin needed emptying after eight days. It pushed aside toys and dragged a phone cable. Called a crushing disappointment. [Source](https://www.techradar.com/home/robot-vacuums/irobot-roomba-205-dustcompactor-combo-review)
- Tech Advisor: Good carpet cleaning and LiDAR navigation, but mopping mostly spread mess and it got stuck on furniture bases and thin table legs. [Source](https://www.techadvisor.com/article/2837405/roomba-205-dust-compactor-combo-robot-vacuum-review.html)

### 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)
