About This Item

Why We Like This Machine

The ConvertaMAX 20 is a compact yet large capacity scrubbber perfect for long hard jobs. Equipped with a solid 8-gauge unitized steel frame that is zinc-plated, yellow cromated and painted to resist rust. Brush motors are protected by an impact-resistant shroud which can be easily removed for service access.

The automatic vacuum shut off device is designed to prevent water from entering the ConvertaMAX 20's vacuum motor and damaging it when the recovery tank is full. There are no hinges to bind or floats to become saturated and fail as seen in other systems. Instead there is a reliable float assembly that is removable from the tank for easy access and inspection.

The ConvertaMAX 20 is a rebuilt walk behind scrubber from model year 2000. It will have a new appearance and is confirmed to be a limited use machine. It has a theoretical coverage rate of 26,500 square feet per hour. Its scrub path is 20" and its transport speed is variable from 0 to 290 feet per minute.
