What reviewers found
iRobot Roomba Max 715 Vac + AutoEmpty Dock
- 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
- 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
iRobot Roomba Plus 515 Combo
- Just A Dad Approved (6.5/10): 3 month real world test: subscores Hassle Free 6.7/10, Mop Performance 7.2/10, Carpet Cleaning 6.4/10, Hair Tangle 5/10, Obstacle Avoidance 7/10. Reported repeated Wi-Fi disconnects that needed hard reboots, hair wrap on the single brush roll, a slightly off map and a filter that can only be replaced. Says the Amazon only 515X is the same robot. Source
- Lifehacker Japan: Hands on with the Japanese model: measured 8.4 cm tall, cleaned under low sofas and cabinet toe kicks earlier Roombas missed, and avoided a camera placed as an obstacle. The review lists no drawbacks and carries affiliate links. Source
