Where it works

High-clearance spaces, mapped and localized with 3D sensing.
Nighttime cleaning runs, which the 3D perception package is built to handle.
Busy public areas, with light and sound alerts for pedestrians and vehicles.
Walls and shelving edges, where the scrubbing brush extends to reach the edge.

Day to day

The BG1 Pro runs up to 7.5 hours sweeping and scrubbing. A charge takes about 3 hours on a supply of 180 volts or more, and about 4.5 hours below that. It carries 75 liters of clean water and 60 liters of waste water, and doses detergent from two tanks of about 7 liters total. It needs an 85 cm path and cruises at up to 1.2 m/s. Unattended operation needs the optional workstation.
