Roborock Q8 Max

This model does not have automatic dust emptying, so you empty the 470 mL onboard bin yourself. For most homes that means every few cleaning runs, and more often with heavy pet shedding.

At 3.8 inches tall, it slides under many couches, beds, and cabinets. Measure your lowest clearance first, since taller-than-usual furniture gaps give it the easiest path underneath.

It clears obstacles up to 20 mm high, so it handles most door sills and low transition strips between rooms without getting stuck.

Yes, the mop offers 30 moisture levels, so you can dial the water flow up for a heavier pass or down to barely dampen delicate hard floors.

You can draw no-go zones in the app to block rooms or spots you want left alone, and it stores multi-level maps for up to 4 floors.
