The new PAS20DX features aggressive cleaning power with 90 lbs of floating contouring brush pressure. To get this pressure with other scrubbers, you have to use a fixed setting. The easy to use PAS20DX features a 20 inch cleaning path that fits easily through doorways and into tight spaces. And thick slurry is no match for the 3-stage suction motor that vacuums up the waste at all speed settings. Maintenance is made simpler with easy access to batteries, vacuum motors and tanks, and with lifetime lubrication on the differential motor. The PAS20DX battery operated scrubber provides a run time of up to 5 hours for continuous scrubbing power.
