The Minuteman RoboScrub 20 is a ride-on floor scrubber that also drives itself. An operator teaches a route once, then BrainOS software, 2D and 3D cameras and lidar let the machine repeat it on its own, steering around people and obstacles and stopping when it cannot get past. Autonomous operation requires a subscription to Brain Corporation Autonomy Services, and operators must be trained by Brain Corporation or an approved trainer.
It scrubs a 20" path with 16 gal solution and recovery tanks and runs up to 4 hours on two AGM batteries. Grocery stores, shopping centers, warehouses and production halls use it to take repetitive floor passes off their crews, and anyone trained can take the seat for a quick manual clean.
Features
Teach-and-Repeat Routes
Drive a route once in teach mode and the machine stores it; multiple routes can be repeated on command from the password-protected touchscreen.
Cameras, Lidar and Sensors
Overlapping 2D and 3D cameras and lidar map the surroundings, pick out people and obstacles and plan a way around them.
Safety Built In
Two auto-stop buttons, a horn, anti-joyride detection, turn signals and a flashing beacon protect people when it works alone.
Remote Monitoring
Brain Corp's Robot Operations Center handles mobile alerts, usage tracking, productivity reports and remote diagnostics.
Aqua Stop Brush
A banded disc brush with soft nylon bristles holds the water inside the brush deck, limiting overspray and water use.
Manual Ride-On Mode
The same machine converts to a conventional rider for spills and quick jobs, rated at 24,500ft²/hr and 3 mph when driven.
AGM Batteries for Long Shifts
Two sealed, maintenance-free 234 Ah AGM batteries give up to 4 hours of run time; recharging takes 7 to 8 hours.

Setup & Placement
Charge the two AGM batteries fully on the off-board charger before the first shift. Autonomous operation requires an active Brain Corporation Autonomy Services subscription; an operator trained by Brain Corporation or an approved trainer then teaches each route by driving it once in teach mode, and the machine is ready to repeat it on its own.
