Abstract
A surface cleaning implement has a suction nozzle, a fan in fluid communication with the suction nozzle, a suction-driven turbine motor for driving the fan and a magnetic coupling between the fan and the motor. The surface cleaning implement can be in the form of an accessory tool that has a housing with a suction opening adapted to be connected to a vacuum hose and mounting the suction nozzle, the fan and the motor and the housing mounts a recovery tank that is in fluid communication with the suction nozzle. The accessory tool can further comprise a fluid dispensing assembly for storing and distributing fluid to the surface to the cleaned. The fluid dispensing assembly can comprise a turbine-driven fluid pump.
Claims7
A surface cleaning implement, comprising:
- a suction nozzle;
- a fan in fluid communication with the suction nozzle;
- an air-driven turbine for driving the fan;
- and
- a magnetic coupling between the fan and the turbine, wherein rotation of the turbine effects rotation of the fan.
