Most buyers say this Roomba tackles everyday pet hair and scheduled cleanups reliably, with mapping that lets you target specific rooms. The trade-off is that you'll likely need to rescue it from dead batteries or occasional app glitches, so it's not fully hands-off.
Loved by buyers
- •Mapping is precise enough to clean by room, not just random bump and go.
- •Rubber brushes resist pet hair tangles, saving you from cutting out wrapped hair.
- •You can schedule cleanings per room, which helps manage heavy-traffic zones day to day.
Buyer concerns
- •Battery often dies before the vacuum can dock, leaving you to carry it back to the base.
- •App and cloud connectivity drop unexpectedly, disrupting schedules and remote starts.
- •Customer support is slow to respond and rarely solves problems the first time.
