About the Square Scrub
Floor Surface Preparation Machine
Square Scrub’s EBG machines are American Made. Our EBG Surface Preparation machines offer
removable weights, a minimum 1.5hp, 1725rpm motor, powder coated 10 gauge steel, heavy
duty frame, and 6”x2” non-marking ball-bearing wheels with a heavy duty ¾” solid steel axle.
Removable weights not only make our machine easy to transport but allow users to tailor the
weight to suit their project needs.
With a selection of over 30 different surface preparation pads, there really is only one machine
for the job. The Square Scrub EBG Surface Preparation Machines are designed to make the most
efcient use of every pad, paper or screen used with the machine, saving both time and MONEY.
