Powered Back Scrubbing Apparatus

Abstract

A powered wall-mounted back washing apparatus is a device the aids in the washing and exfoliating of one's back during the activity of taking a shower. The device is designed to be permanently installed on the shower wall. The apparatus aids in the washing of one's back by the mechanism of multiple short rotation brush assemblies and nozzles providing soap and/or water in succession. Each nozzle assembly is connected to a pump and tubing system, which in turn is attached to a reservoir that will provide soap and/or water at the point of contact with person's back. A self-contained reservoir may be filled with soap and water by user prior to use. The apparatus functions by the activation of the pumps providing both soap and water in sequence along with constant semi-rotation of the brush assemblies. This ergonomically-designed invention provides superior washing functionality and ease of use.
