A cordless scrubber-dryer that a custodian pushes by hand. It is not autonomous. It scrubs and pulls the water back up in one pass, so the floor dries behind it.

Where it works

Kitchens and restrooms: the greasy or wet floors PUDU built it for.
Dining areas, since it is cordless and weighs 17 kg.
Small buildings and offices that have no ride-on scrubber.
Glass, tiled walls and tight corners, with the vertical and edge attachments.

Day to day

The SH1 runs 70 minutes in standard mode and 100 minutes in ECO mode, and charges in 2.5 hours. It cleans a 44 cm path with a 49 cm squeegee and holds 4 liters of solution and 4 liters of recovered water. PUDU rates it at 1,100 to 1,600 m² per hour. The screen warns when the recovery tank is full, the solution is low or a motor faults, and walks a new user through brushes, squeegee and tanks.
