Most owners agree the M3 Ultra delivers powerful vacuuming and a self-emptying dock that genuinely reduces daily maintenance. The mopping system, while automated with hot water and drying, suffers from pads detaching on rugs, so buyers should be prepared for occasional manual intervention if mixing carpets and mopping.
Loved by buyers
- •The 23,000Pa suction paired with the anti-tangle brush pulls pet hair from carpets and hard floors efficiently.
- •The self-emptying dock with its 3.2L bag means you can go up to 120 days without touching dust.
- •Hot water mop washing and cool air drying keep the pads clean and prevent musty odors.
Buyer concerns
- •The mop pads can slip off when passing from hard floors to rugs, so you may find them detached mid-clean.
- •The robot tends to avoid going under low furniture even when there's enough clearance, leaving those areas untouched.
- •Battery life falls short for cleaning an entire large home in one session, and a full recharge takes about four hours.
