Narwal Freo Z10 Ultra

The dock stands 17 inches tall and 18.2 inches wide, so plan for a clear spot near an outlet. The robot itself is just 4.3 inches high, letting it slide under low sofas and cabinets.

Yes. It supports multi-level maps for up to 4 floors, so it keeps a separate layout for each level. No-go zones let you block off areas you want it to avoid.

The dock washes the pads with hot water at 167°F and then air-dries them at 104°F. Automatic detergent dispensing keeps the pads cleaner during each wash cycle.

The 2.5 L dust bag holds weeks of debris before it needs changing, and the 4.5 L clean tank plus 4 L dirty tank last many mopping sessions between refills. Auto tank refilling tops up the robot mid-clean on its own.

It clears obstacles up to 20 mm high, so most door sills and low transitions are no problem. Its dual LiDAR and camera system steers around furniture legs and clutter along the way.
