E531R
Compact and Powerful LiFePO4 Rider Scrubber
Cover More Area
This feature-rich machine is capable of wet washing up to 37,000 square feet per hour thanks to its 20-inch washing path.
Longer Lasting
The 1*24V100Ah LiFePO4 battery offers 5,000 charge cycles versus 600 cycles from a traditional battery.
Easy-to-Use
Despite its smaller size, the 531R features dual 18.5 gallon solution and recovery tanks that are conveniently located and don’t require tools to disassemble.
Heavy-Duty Power
This quick and agile cleaner boasts dual 550W brush and drive motors, 180 rpm brush speed, 80 lbs of down pressure, and a powerful 400W vacuum motor.
The E531R’s frameless chassis design is compact, lightweight, and offers a tight turning radius suitable for areas that require maneuverability, such as hallways and around corners. This industrial floor cleaning machine can handle a wide variety of floor surfaces and is especially suited for facilities with heavy foot traffic.
The patented, die-cast aluminum brush deck and squeegee assembly automatically loads and unloads the brushes with the push of a button, helping to extend the brush plate’s lifetime and minimizing the risk of user error or damage.
A user-friendly control panel is waterproof and includes an LCD display, easily identifiable cleaning mode buttons, solution volume adjusting button, emergency stop button, speed controls, horn, and a front LED lamp button. The seat is equipped with a safety switch that automatically stops the machine when the driver leaves the seat.
