The small 13.5" cleaning path is great for small sized retail and office spaces. Equiped with an array of standard feature, and a lithium ion battery, the SC250 is a competative option within the growing market for home floor scrubbers. The Advance SC250 is activated with a single touch, this button engages all cleaning functions, of which you can choose between either a low or high solution flow rate. The 1.6 gallon tanks are magnetically secured, the single cylindrical broom requires no tools to remove, and the litium ion batter requires no maintenance or worry. An optional second lithium ion battery can be purchased for extended runtimes.
