Aerodynamically engineered radial vacuum line creates a laminar-flow vortex in the cleaning head that allows the SX-12 to remove water twice as fast as competitive models. Toe-adjustable vacuum relief lets you adjust the suction strength on the fly. Low profile allows the unit to fit under toe kicks. Easy access inline filter makes cleaning the filter a snap. Quality components will handle operating pressures from 700 to 1,500 PSI so you can blast away oily deposits. Stainless steel handle and high-tech polymer casing will take a beating and ask for more. Handles are spaced shoulder-width and allow you to use side-to-side or front-to-back cleaning strokes. Lightweight construction makes it feel like the machine is floating along the floor. Tool length is comfortable for users of all heights. Easy gliding on surfaces for low fatigue usage. Works on uneven stone or tile surfaces or smooth concrete.
