Description

BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to a wet cleaning device having a controller with a shut-off valve, an extension bar, and a cleaning element using pressurized fluid.

2. Description of the Prior Art

There are many cleaning devices presented in the earlier arts intended to be used for cleaning. In the U.S. Pat. No. 6,336,241 B1, Wilson presents cleaning device for cleaning a number of hard to reach places with less difficulty. In U.S. Pat. No. 6,966,720 B2, Moss presents toilet cleaning apparatus comprising a toilet brush head, toilet brush handle separated from the brush head by a brush shaft. In U.S. Pat. No. 6,804,853 B2, Wang presents a cleaning device that includes a first cleaning member attached to a lower end of an elongated rod, and a second cleaning member mounted slidably on the first cleaning member. However, none of them devised and utilized are known to wet cleaning, which consist of a controller with a shut-off valve for supplying instant fluid, an extension bar or a handle bar for delivering fluid to a remote area, and a variety of cleaning elements for rubbing and scrubbing.

The hand held water sprayer having vertical shut-off valve presented in the U.S. application No. 20,050,121,542 is suited to supply water for a cleaning device in a manner of easy push on-and-off operation. It has been modified to a cleaning device, which includes a controller, an extension bar, and a cleaning element. The word “fluid” in the current invention defines liquid for cleaning agents including water and chemical solutions. The controller supplies instantaneous fluid supply with a shut-off valve which may be any type of control valve system including the vertical shut-off valve issued in U.S. Pat. No. 7,000,898 B2. The shut-off valve can be operated by a pushbutton with a push-on-release-off or a push-on-push-off. The extension bar having an internal channel and a protecting guard, delivering fluid to a remote place. The extension bar can be replaced with a handle bar which has an external channel for supplying fluid. The splash guard can be mounted for protecting from fluid splash, but it can be eliminated for the use in a small area. A variety of cleaning elements are presented for various cleaning purposes and the more can be obtainable within imagination. The current invention presents some of them as illustrations to supply the instant cleaning fluid with a controller with shut-off valve to the cleaning element through the extension bar.
