Mova S20 Ultra

The robot stands 4.1 inches tall, so it slides under most sofas and cabinets with a few inches of clearance. The dock is larger at 23.2 inches tall and 19.4 inches deep, so plan floor space near an outlet.

The dock uses a 3.2 L dust bag, so it holds weeks of debris before needing a swap. Its 4.5 L clean water tank and 4 L dirty water tank also last many sessions between refills and empties.

It clears obstacles up to 20 mm tall, so it can cross most door sills and low thresholds between rooms without getting stuck.

You can set no-go zones and store multi-level maps for up to 4 floors. That lets you block off areas and pick specific rooms to clean on each level.

The dock auto-washes the pads with water heated to 140°F and adds detergent automatically. It also air-dries the pads afterward, which helps prevent musty odors between cleans.
