Buying Guide

What should you consider when choosing a walk-behind floor scrubber?

  • Space size and layout: For tight aisles and small offices, choose compact models with 11–15 inch paths. For larger corridors, look for 17–22 inch scrub paths and larger recovery tanks.
  • Power source and run time: Cordless options improve mobility but require battery management. Battery-powered units with 2–3 hour runtimes fit standard shifts; plan for recharging between sessions in longer shifts.
  • Tank capacity and water control: Larger solution and recovery tanks reduce refill interruptions. Look for integrated water control valves to minimize manual adjustments during cleaning.
  • Surface compatibility: Consider tanks and brushes suited to tile, epoxy, terrazzo, VCT, and sealed stone. Some models clearly specify multi-surface use, while others excel on hard floors.
  • Maintenance and parts: Pad options, squeegee width, and brush rpm impact cleaning efficiency and maintenance needs. Ensure availability of replacement pads and brushes for your chosen model.
