Buyer’s Guide: What to Consider
Choosing the right walk-behind scrubber involves evaluating several key factors to match your facility’s needs. This guide highlights the most important considerations to help you make an informed decision.
- Cleaning Width: The cleaning width determines how much floor you cover per pass. Wider widths like 22 inches are best for large areas, while 15-18 inches suit smaller spaces. Consider your facility size to choose the right balance between speed and maneuverability.
- Tank Capacity: Larger solution and recovery tanks mean fewer stops for refills and emptying. For big facilities, tanks over 15 gallons are ideal. Smaller tanks (under 10 gallons) are fine for compact areas but require more frequent maintenance.
- Battery Runtime: Battery life dictates how long you can clean without recharging. Look for models with at least 90 minutes of runtime for typical shifts. Lithium batteries offer faster charging, while GEL batteries provide consistent power. Match runtime to your cleaning schedule.
- Floor Compatibility: Not all scrubbers work on every floor type. Some are designed for sealed hard floors like concrete, tile, or epoxy, while others can handle marble or sealed wood. Always verify the machine's compatibility with your flooring to avoid damage.
- Motor Power: Motor wattage affects scrubbing and suction performance. Higher wattage (500W or more) provides better agitation and water recovery. Brushless motors are more durable and require less maintenance, making them a worthwhile investment for heavy use.
Conclusion
Selecting the best walk-behind scrubber depends on your specific cleaning requirements, including floor type, area size, and operational budget.
