摘要:
A novel upright carpet cleaning extractor is disclosed which may be conveniently converted from the floor cleaning mode to the upholstery and/or stair cleaning mode. The overall configuration and operation of the extractor is similar to that of a typical upright vacuum cleaner and may be operated in the forward or reverse direction similar to a typical upright vacuum cleaner. When in the floor cleaning mode, cleaning solution is supplied to a solution distributor by gravity flow. However, when converted to the upholstery cleaning mode an auxiliary, air turbine driven cleaning solution pump is automatically energized for supplying pressurized cleaning solution to an upholstery or stair cleaning nozzle.
