If your Hoover carpet cleaner stops working or does it in a wrong way, there may be clogging. To solve this problem, unplug the device and remove both water tanks. Lay the cleaner on the floor, remove a nozzle, and rinse it with water or pull the clog manually if possible. Then dry the nozzle and put it back. Note that each nozzle requires definite way of fixing and removing, so be sure to consult the manual before replacement actions.
