The Gausium Scrubber 50 Pro is a full size autonomous floor scrubber that scrubs, sweeps and dust mops large open floors such as stores, airports and warehouses. It is worth considering for big sites with staff cleaning the same floors every night. At $53,600 to buy, most buyers should compare the $979 a month rental before committing.
What the Gausium Scrubber 50 Pro is
The Scrubber 50 Pro is a commercial cleaning robot from Gausium, sold and serviced in the US by RobotLAB RobotLAB Scrubber 50 Pro ↗. It combines scrubbing, sweeping and dust mopping in one machine and drives itself using 2D LiDAR, a 3D depth camera, an RGB camera and anti collision sensors RobotLAB Scrubber 50 Pro ↗.
It is large. The robot measures about 31.9 by 27 by 42.1 inches and weighs 346 pounds with the disc brush RobotLAB Scrubber 50 Pro ↗. It needs a passage at least 31.5 inches wide and 43.3 inches to make a U turn RobotLAB Scrubber 50 Pro ↗.
It can use a 460 mm (18.1 inch) disc brush or a 406 mm roller brush that reaches 780 mm (30.7 inches) with side brushes RobotLAB Scrubber 50 Pro ↗. It docks itself automatically and supports multiple floors, which RobotLAB pitches for lights out cleaning programs RobotLAB Scrubber 50 Pro ↗.
What it does well
Coverage is high. RobotLAB gives a practical cleaning rate of 5,382 to 13,993 square feet per hour, with theoretical maximums above 18,000 square feet per hour RobotLAB Scrubber 50 Pro ↗. That is the scale of a big box store or terminal, not an office.
It holds a lot of water and reuses it. The clean water tank is 30 liters and the recovery tank 24 liters RobotLAB Scrubber 50 Pro ↗. A five stage filtration system recycles cleaning solution, which RobotLAB says cuts fresh water use by about 80 percent, lowers detergent costs and stretches the time between refills RobotLAB Scrubber 50 Pro ↗.
It looks for messes. An Auto Spot Cleaning feature uses the RGB camera and AI to detect waste and stains and clean those spots again RobotLAB Scrubber 50 Pro ↗. Gausium claims up to a 400 percent efficiency gain over fixed path cleaning; that is the maker's own figure RobotLAB Scrubber 50 Pro ↗.
Support is local. RobotLAB says it handles sales, site assessment, mapping, staff training, ongoing support and repair across the US, and offers a free 30 minute live demo RobotLAB Scrubber 50 Pro ↗.
Where it falls short
Scrubbing runtime is short. The 60 Ah lithium iron phosphate battery lasts about 3 hours when scrubbing, or 6 to 8 hours when dust mopping, and takes 2 hours to charge RobotLAB Scrubber 50 Pro ↗. Plan for a charge break on long scrub shifts.
It is expensive to buy. At $53,600, it costs more than many compact scrubbers in RobotLAB's range RobotLAB cleaning robots ↗. For an office or small shop, it is far more robot than you need.
Key details are missing from the product page. RobotLAB does not list warranty terms, noise level or elevator support for this model RobotLAB Scrubber 50 Pro ↗. Ask about all three, plus what service and replacement parts are included, before you sign.
It needs open floor. Its size and turning space make it a poor fit for tight aisles or cluttered rooms RobotLAB Scrubber 50 Pro ↗. Hands on testing is in progress; we will update this review with results.
