The CONTRACTOR HYDRO TWISTER® is the proven choice for professional surface cleaning…with four tools for your cleaning needs. The Contractor Twister combines a rotary surface cleaner, spot / gum remover, hydro broom, and an edger to create an all-in-one deluxe surface cleaner. The dual trigger guns activate either the stainless rotary spray arm or one of the other three devices. By combining four processes into one unit, you will save time and fatigue when cleaning large expanses of concrete, parking lots or other flat surfaces. The secret that makes the Contractor Hydro Twister so effective is the ideal water spray angles and nozzle heights that optimize cleaning power.
