We see most owners agreeing this robot vacuum delivers strong pickup on both hard floors and carpets, and the self-emptying base keeps daily maintenance remarkably low. The main trade-off is that mapping can be inconsistent in large or cluttered homes, and the magnetic mop pads may detach when crossing rugs, so you may need to tweak placement or run separate vacuum and mop cycles.
Loved by buyers
- •20,000Pa suction picks up embedded pet hair and fine dust in a single pass, even on medium-pile carpets.
- •3.2L self-emptying base holds up to 90 days of debris, so you rarely touch the dust bin.
- •Hot water dock washing and cool air drying prevent mop odor, keeping the mopping system fresh without extra work.
Buyer concerns
- •Onboard mapping struggles to cover entire homes, especially under low furniture or in long layouts, often missing rooms unless the dock is centrally placed.
- •The magnetic mop pads frequently detach when the robot transitions from hard floors to rugs, halting cleaning and requiring manual reattachment.
- •No extendable side brush means it leaves debris right along baseboards and in tight corners.
