ABSTRACT:
A novel solution for converting a walk behind floor scrubber into a sit and ride behind floor scrubber. The present invention consists of a chassis frame to which five wheels are attached. Two of the front wheels pivot and the up-front safety wheel does not. The wheels that are attached to the rear of the frame, are non-pivotal. A person sits on the cushioned seat. Upon grabbing the floor scrubber's control handles and rotating them forward the floor scrubber, as it propells forward, pulls the present invention behind it in tandem. This allows the operator for the floor scrubber to sit and rid instead of walking, while cleaning large commercial size floors. This new procedure saves enormous time and the person controlling the scrubber will be less fatigued from hours of walking. The Scrub-mate is new to the floor cleaning industry, because it eliminates walking of the operator while using a battery-powered walk behind floor scrubber.
