Mova MOBIUS 60

It empties into a 3.2 L bag and holds 5.5 L of clean and 4 L of dirty water, so most homes go weeks between refills, and the dock even cleans its own base.

At 3.5 inches tall, it slides under most sofas, beds, and cabinets with room to spare.

It clears obstacles up to 80 mm, handling tall thresholds and transitions that stop most robots.

It runs at about 55 dB, on the quieter end for a robot vacuum, so it is easy to run while you are home.
