The HD-30 Flex autoscrubber is an almost indestructible, dual-brush, battery-powered, automatic floor scrubber built with 18.5 gallon stainless steel solution and recovery tanks and manual squeegee control for maximum productivity. Variable down pressure easily adjusts for lightest to heaviest duty scrubbing. A modular plug-in scrub head, modular pump motor and control assemblies give fast and easy maintenance. Includes a 3 year warranty on pumps and motor. It's the perfect addition to your large facility floor cleaning equipment. With this machine we recommend using a floor scrubbing solution with two 15" inch red scrubbing pads for light duty scrubbing, two 15" blue scrubbing pads for medium duty scrubbing, or two 15" green scrubbing pads for heavy duty cleaning. Be sure to look at our other Mercury automatic floor scrubbers and many other brands of walk behind floor scrubbers, as well as our full line of ride on automatic floor scrubbers.
