The Doodle Scrub EBG-9 by Square Scrub is our most compact machine. Just because it's small doesn't mean it isn't powerful. The Doodle Scrub packs just as much punch as our bigger EBG machines, but with small exception - THE DOODLE SCRUB GOES WHERE OUR BIGGER MACHINES CAN'T. At 21 pounds, the Doodle Scrub delivers nearly the same pounds per square inch as the EBG-20/C.
