Gausium Scrubber 50 Pro vs LionsBot R3 Scrub Pro: Heavy-Duty Floor-Scrubbing Robots

The Scrubber 50 Pro combines three jobs — scrubbing, sweeping and mopping — in one machine. It is 107 cm tall, weighs 157 kg and drives at up to 1.2 m/s. Runtime depends on the mode: from 3 to 8 hours. Navigation uses 2D LiDAR, a 3D depth camera, an RGB camera and a collision sensor, and a stain-recognition system decides where to add cleaning. A five-stage water-recycling loop cuts fresh-water use by about 80 percent.

The R3 Scrub Pro is lighter at 85.3 kg, which is 71.7 kg less, and slower at 0.83 m/s, about 30 percent below the Gausium. It combines LiDAR, ultrasonic sensors and an RGB-D camera, and a full charge takes 2 hours. The material available gives no dimensions or battery runtime for it, so this pair of parameters cannot be compared. Throughput in a large hall depends on speed, scrubbing width and runtime, so before buying ask for the datasheet and a trial on your own floor (“How to Read a Robot Datasheet”).

The price gap is large. RobotLAB lists the Scrubber 50 Pro from USD 53,600, or about PLN 207,760 (≈ EUR 47,610) at the rate of 3.8762 on 1 October 2026; RaaS is USD 1,795 a month. The R3 Scrub Pro costs USD 31,250 (about PLN 121,131 (≈ EUR 27,760)) or USD 869 a month. The Gausium is therefore USD 22,350 dearer, about 72 percent, and more than twice as much on subscription. Per unit of speed it comes to about USD 44,700 per m/s for the Gausium and about USD 37,650 for the LionsBot, so the gap narrows to around 19 percent.

No Polish distributor or service has been confirmed for either robot. Gausium publishes nothing about sales in Poland, and LionsBot works through RobotLAB and partners in Europe. Importing means adding transport, VAT and service; we describe how to calculate total cost in “Humanoid Robot TCO: How to Calculate Total Cost”. The robotisation tax relief covers industrial robots in a strictly defined sense, so whether a scrubber qualifies is for a tax adviser to decide (“Poland's Robotization Tax Relief”).

The Scrubber 50 Pro targets retail, logistics, airports and industry, meaning large, open floors (retail, warehouses). Over several thousand square metres, higher speed and a runtime of up to 8 hours make it easier to finish cleaning within one shift. The R3 Scrub Pro, intended for retail and logistics, is enough for a smaller site or a warehouse where the route is shorter and the budget limited. For dry vacuuming the same maker offers the LionsBot R3 Vac, and an alternative from another shelf is the Nilfisk Liberty SC50. Choosing equipment for large halls also touches the safety of people and forklifts moving around it; the segment is covered in the category “Service robots”.
