20090044833 | Stabilized vertical surface cleaning - A cleaning system for cleaning a surface comprising: a frame for the cleaning system; a liquid supply source; a liquid applicator; and at least one thruster on the frame to provide force against the frame to maintain support with the surface to be cleaned. A surface is cleaned by providing the cleaning device, moving the cleaning device both horizontally and vertically along the surface, and stabilizing the cleaning device with at least one thruster emitting a fluid stream comprising gas. | 02-19-2009 |
20110048456 | Automated cleaning system for structures - A washing system for an elevated surface has a) a housing having a liquid application cleaning system therein; b) a support element that supports and elevates the washing system; c) a rigid member extending from a surface of the housing that faces away from a surface to be cleaned so that the cable, when supporting the cleaning system against the surface to be cleaned and connected to the housing at a connection point, exerts a rotational force on the cleaning system in relation to the fixed fulcrum at the roof top; and d) weights provided at a distance and direction from the connection point fulcrum to at least in part counterbalance the rotational force. | 03-03-2011 |
20110180098 | Apparatus and method for cleaning surfaces - A cleaning apparatus and method for cleaning generally upright surfaces, walls and windows of a building has a frame rotatably supporting one or more brushes adapted to engage the upright surface of a building. A davit supported on top of the building is connected to a cable pendently supporting the frame and brushes. A winch driven with a motor mounted on the frame operably connected to the cable operates to move the frame and brushes relative to the upright surface. A counterforce generator mounted on the frame establishes a force on the frame and brushes that maintains the brushes in effective continuous engagement with the upright surface during cleaning thereof. | 07-28-2011 |

20140124428 | UNIHOUSING PORTABLE WATER FILTRATION SYSTEM - A water improvement/purification container has: a) an elongated housing; b) a water entry; c) two water exit ports adjacent one distal end of the housing; d) the water port providing supply water first to a macrofilter within the housing; e) the intermediate water source exiting the macrofilter flowing into a reverse osmosis membrane; f) the intermediate water being separated into two streams, g) the first stream being vented through the second of the two water exit ports; and h) the second stream being vented out of the housing as waste water through the first of the two water exit ports. | 05-08-2014 |
20150047675 | System and Apparatus for Washing Vertical Surfaces and Related Methods - A system for delivering purified water is disclosed, comprising a pressure vessel with a first end and a second end, each end adapted to receive a single use water treatment cartridge, and first and second single use water treatment cartridges. The pressure vessel has a first cartridge adaptor at the first end, and a second cartridge adapter at the second end; a first quick connect coupling between the first cartridge and the first cartridge adaptor, and a second quick connect coupling between the second cartridge and the second cartridge adaptor. Methods of fabricating single use water treatment cartridges and using said cartridges to clean glass surfaces are disclosed. | 02-19-2015 |
