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
- 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
iRobot Roomba Plus 405 Combo
- Vacuum Wars (1.66 Vacuum Wars stars): Measured 0.13 kPa suction and 10 CFM airflow against 0.83 kPa and 16 CFM averages, 58% carpet deep clean against 75%, 50% flattened pet hair against 66%, and 5.20 g of water left behind. Dried stain score of 145 beat the 93 average. Called it a letdown. Source
- BestReviews: Tested in a 1,000 sq ft two level apartment. Picked up 90% to 95% of faux fur on hard floors but under 50% on carpet, spread spilled water, tangled on cords twice in one run, and the dock measured 80 to 85 dB when emptying. Testers did not recommend it. Source
