A compact robot that sweeps, scrubs, vacuums and dust-mops, with a front-sweep, rear-scrub design that cleans dry debris and wet stains in one pass. It fits aisles 50 cm wide and cleans during business hours.

Where it works

Narrow aisles and complex layouts during business hours.
Hardwood and marble floors, left dry in one pass.
Grease, footprints and other stubborn stains, with hot water up to 85°C (185°F).
Floors with carpet, where it detects carpet edges and lifts the roller to keep carpets dry.

Day to day

The ET1 runs 2.5 to 4 hours on a 35 Ah battery and charges in about 3 hours. It carries 8 liters of clean water and 7.2 liters of waste water, and its 2.5-liter dust box empties automatically, so disposal is about once a week. The 8-in-1 docking station charges it, cleans the roller, rinses the squeegee, spin-dries the roller, refills and drains water, doses cleaning agent and heats water. It maps a new area on its own, with no pre-mapping.
