Start with the work the scrubber must do and the space it must fit. Then compare suitable models within your preferred brands. Existing equipment, operator familiarity and parts requirements can influence your brand choice. Check that the model also suits the building and the cleaning tasks.

With a walk-behind scrubber, the operator walks behind the machine. A ride-on scrubber has a seat, while a stand-on model carries the operator on a standing platform. Compare the complete machine dimensions, turning room, operator position and cleaning capacity when choosing between these formats.

Compare the exact model and condition, battery and charger, brush or pad driver, cleaning path and tank capacities. Ask what the price includes and review any applicable taxes, delivery charges and warranty terms. Two quotes for the same model name can cover different configurations or included equipment.

The solution tank holds clean water or the specified cleaning mixture. The recovery tank collects dirty liquid removed from the floor. Separate tanks keep recovered soil out of the fresh cleaning supply. Compare both capacities, along with how the tanks are filled, drained and cleaned.

Measure the narrowest doorway, aisle and elevator entrance on the cleaning route. Compare these measurements with the machine’s overall width, squeegee width and turning requirements. If an elevator is involved, also check its capacity against the operating weight of the machine, water, batteries and operator where applicable.
