A large sweeper-scrubber that sweeps and scrubs in the same pass, sized for large open floors: cafetoriums, fieldhouses and event spaces.

On a campus

Cafetorium floors after lunch, and again after an evening event.
Fieldhouse concourses and lobbies on a nightly route.
The long main corridors of a large high school.
District event centers between bookings.

Day to day

The BG1 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 on its own from two tanks. It needs an 85 cm path and cruises at up to 1.0 m/s. Running unattended needs the optional workstation. The BG1 Pro adds a 3D LiDAR package and a 1.2 m/s top speed.
