Embodiments of the invention disclosed herein include steam appliances and methods which apply steam and a liquid containing a cleaning agent to the floor via separate outlets. In some embodiments, the liquid containing a cleaning agent is applied to an area of the floor that is physically separated from a steam application area. The steam may be applied to the floor through a steam-permeable fabric. The liquid containing a cleaning agent may be heated before being applied to the floor or being mixed with steam.

Steam cleaning appliance

Portable workbench

A nozzle assembly including a nozzle turret rotatably mounted on a body. The body has a face, an outlet in the face, and an annular seat in the face, surrounding the outlet. A relatively non-compressible strut extends from the face of the body, while a relatively non-compressible spacer abuts the face. A compressible sealing member is positioned in the seat and, when not compressed, extends out of the seat and further from the face of the body than the spacer. The turret has a bore rotatably received on the strut, and the turret abuts the spacer. Nozzles are arrayed in the turret such that the nozzles sequentially align with the outlet of the body as the turret is rotated on the strut. A fastener secures the turret to the strut such that the turret compresses the sealing member to provide a fluid-tight seal between the outlet and the nozzle aligned with the outlet. According to one embodiment, the nozzle assembly further includes structure for indexing the rotation of the turret with respect to the body. According to another embodiment, the nozzles are removably mounted within the turret.

Nozzle assembly

A control valve assembly designed to allow operation with minimum power requirements and a rapid response to a 'shut off' command. The assembly includes a pair of seal elements which operate in tandem. When the valve is open, fluid passes through a series of chambers and as the valve is closed, a substantial passageway allows fluid to bleed quickly to the outlet and reduce pressure to zero almost instantly, thus achieving almost instant shutoff. The dual seal arrangement is also designed so that internal fluid forces are nearly balanced so that minimal external power is required for proper operation.
