Cen-Tec Systems is pleased to introduce the new response II CT25QD power nozzle, which combines features typical of premium power nozzles with a unique self regulating air by pass system which automatically adjusts air flow to floor conditions permitting a true deep clean in a system designed to move freely over even the highest density soft carpets. Power nozzles on traditional carpets permit the air to flow under the agitator, traveling up and back carrying the dirt into the air stream. The new high density soft carpets prevent the air to enter through this traditional means. The challenge was to develop a solution which adjusts to meet carpet conditions while still keeping the air stream entering under the agitator for an effective clean. Other systems vent, but much of the air is wasted traveling over the agitator not under where it is most effective in carrying away dirt. The CT25QD allows a self adjusting air relief entering through vents in the hood of the nozzle. The result is no wasted air flow, effective cleaning and a self regulating system that works as well on traditional carpets as it does on the new high density ultra soft carpets.
