The Duo combines all the performance and productivity benefits of the Superpro unit with the added feature of a Bypass motor. This means that if there is accidental suction of moisture or liquids, the motor is fully protected against electrical failure, unlike a back pack with a conventional Flo-thru motor. This saves time and costly repairs. Ideal for any application where moisture may be present on the flooring Includes hoses, wands, floor tools and bags Integral cord restraint and on board tool holders Popular with hotels, bars, schools and aged care facilities.
