A 12-inch cleaning path helps the Port A Scrub to fit into tight or congested areas. Due to its compact design, this machine can be operated under shelves, tables and chairs, i.e. in places where other machines cannot reach. The Port A Scrub puts the water and chemical down, scrubs with two counter rotating cylindrical brushes and picks up the dirty water, leaving the floor virtually dry. Running at a low noise level of 69 db, operation is possible in noise sensitive areas. This machine has four height settings for brush wear and brush height. Brushes are easy to remove and change, no tools are required. A one gallon clean water tank is conveniently located on the handle and is easily removed for quick filling.
