Rotating fluid jet cleaning system for vertical walls

摘要

An improved system for cleaning vertical walls includes a vacuum source to adhere the system to the vertical wall. The vacuum source removes fluid and removed material from the wall, and also adheres the system to the wall. A rotating fluid jet is positioned radially inwardly of the vacuum source and impinges high pressurized fluid off of the surface to be cleaned to remove material. In a preferred embodiment, a central portion mounts both the fluid source and the vacuum source. A base portion mounts motors for driving the system along the wall. The base portion rotates relative to the central portion such that the central portion does not move as the base portion turns on the wall to drive the system along the wall. In a further feature, an additional air flow system is provided to provide supplemental air flow to assist the vacuum when moving the fluid and removed material.
