Washworld’s patented Virtual Attendant® technology enables the Razor XR-7 to maneuver around obstacles such as wide mirrors, rear mounted bike racks and extended trailer hitches which often render other washes inoperable. Virtual Attendant automatically compensates for the obstacle, thereby allowing the wash to be completed. This means no down time, no attendant and no more trips to the site to reset the wash! Best of all...it is standard on every Razor XR-7 wash!
