1. A fluid control device for vacuum cleaning comprising:
- a tube having a first end and a second end;
an air valve disposed in the tube, the air valve being movable between a first valve position wherein the air valve substantially prevents air flow through the tube and a second valve position wherein the air valve allows air flow through the tube; and
a handle disposed in communication with the valve, wherein the handle is movable between a first handle position and a second handle position, and wherein the handle is operatively connected to the air valve such that the air valve is in the first valve position when the handle is in the first handle position, and such that the air valve is in the second valve position when the handle is in the second handle position.

Abstract
A vacuum cleaning device provides improved removal of dirt and cleaning solution while using less air flow than conventional cleaning devices, requiring less power to operate. The device utilizes an air control valve which may or may not be coupled to a liquid valve. An existing power system may then be used to operate additional cleaning devices.

13. A fluid control device for vacuum cleaning comprising:
-
a tube having a first end configured for attachment to a hose providing suction and a second end comprising a vacuum cleaning wand;
an air valve disposed in the tube, the air valve being movable between a first valve position wherein the air valve blocks air flow through the tube and a second valve position wherein the air valve allows air flow through the tube;
a handle operatively connected to the air valve, such that movement of the handle moves the air valve into the second valve position. - View Dependent Claims (14, 15, 16, 17, 18)
