## What reviewers found

### iRobot Roomba Max 715 Vac + AutoEmpty Dock

- PCWorld: Initial mapping took about 13 min. Strong on a rug but weak on hard floors at Standard suction until Deep or Smart mode. Handled furniture well but pushed through shoes and chewed up magazines. Loud auto empty. [Source](https://www.pcworld.com/article/3265229/roomba-max-715-vac-review.html)
- Just A Dad Approved (6/10): Three months of home use: carpet 8/10, clutter test 8.5/10, hair tangle 6/10. The dock failed to fully empty the bin in 5 of 5 tries and moist mess pickup failed. [Source](https://justadadapproved.com/product/irobot-roomba-max-715-pet-robot-vacuum-review/)

### 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)
