New Advance SC901 Walk-Behind Scrubber
Our Take (from the SES Sales Team)
"The Advance SC901 walk-behind floor scrubber was introduced in 2022 to replace the popular Warrior, which had been sold for many years previously. I recently sat down with the unit and gave it a try, and I have to say, I was really impressed! Most major manufacturers will have a large walk-behind floor scrubber, but what sets the Advance SC901 apart from the others is its simplicity. It has a mechanical foot pedal that requires minimal effort to use and eliminates an actuator that can get damaged. The control panel is easy to understand, and the tank sizes are among the largest in the industry. With the addition of EcoFlex, you can control the chemical mixture from the front dashboard, eliminating one of the biggest errors people make by adding too much chemical into the water. The unit is equipped with pneumatic tires, allowing for smoother movement over uneven surfaces. It is available in sizes ranging from 28 to 34" and with the option of disk or cylindrical scrub decks. If you are in search of a dependable unit from one of the top manufacturers in the industry at a more affordable price point that is a true workhorse, then this unit is perfect for you."
A large walk-behind scrubber built around simple, mechanical controls
The Advance SC901™ is a large battery-powered walk-behind automatic floor scrubber with 30-gallon solution and 32-gallon recovery tanks. Advance designed it to remove the complexity common in floor cleaning equipment: there is no control board, the scrub deck and vacuum run on mechanical levers, and the paddle moves the machine forward or, pulled back, in reverse. Fewer electronics mean easier training and more uptime. Advance lists government buildings, transportation facilities, manufacturing plants, general warehouses, municipalities, and beverage distribution and processing plants as typical applications. It comes with a 28-inch or 34-inch disc deck or a 32-inch cylindrical deck.

Reading the model numbers: Nilfisk names each package by deck, batteries, charger and tooling, for example SC901 28D W232 SC PH. 28D, 34D and 32C give the width and deck type (D is disc, C is cylindrical), and an X in front (X28D, X34D, X32C) marks the EcoFlex packages. W232 and W310 are 232 Ah and 310 Ah wet batteries, A255 is 255 Ah AGM and TPPL is a thin plate pure lead battery set. SC is a shelf charger and OBC an onboard charger. PH means pad holders and MGB means MidLite grit brushes.
