HOW DO SURFACE CLEANERS WORK?
High speed flat surface cleaners can consist of 2 or 3 (dual or tri) arms that spin in a counterclockwise direction at up to 1800 RPM (rotations per minute). At the end of each arm you will find a 1/4” MEG 25° spray nozzle that can cover a path from 16” to 30” in diameter, depending on the size of the actual housing. These cleaners can remove dirt up to 15 times faster than standard wands and 10 times faster than water brooms.
Operation: The user walks behind the unit holding the two handles, one of which has a spray gun that works similar to other pressure washer guns. The arms are connected to the shaft that is part of the spinning head (a mechanism that allows smooth rotation of the arm). These arms rotate/spin with the flow of the water (the greater the water volume – the faster the spinning times), which creates a scrubbing action with the water coming out. The spray nozzles are only 1/2” to 2” away from the surface which allows optimized cleaning capabilities. The edge of the housing and the brush skirt protect the surrounding area from over spraying. Some of our models come with the casters and some without. Units without the casters are designed to “hover” or “float” above the ground so that maneuverability increased. The greatest advantage of these machines is that they eliminate the “zebra” striping usually found on driveways and sidewalks.
