A specialized cleaning system for cleaning hard flat vertical surfaces. The specialized cleaning system includes a cleaning brush with an integrated water dispenser, a wiper with an integrated water collector, a separator which separates water from a mixture of water and air that was sucked in, multiple pumps, an optional filter and a water storage tank. As the novel cleaning system and process uses a combination of a water reservoir and a suction pump, the spilling or running of water is prevented. Further, this also allows the system to work in both the direction e.g., from top to bottom of a high-rise building or from bottom to top of the building. Also, the process is a cyclic process i.e. the water from the reservoir is reused in every cycle of the operation.

A substrate processing method includes: performing a both-surface cleaning processing in which a first cleaning body, which ejects the fluid to the one surface or is brought into contact with the one surface, and subsequently moves both the first cleaning body and a second cleaning body, which is in contact with the remaining surface of the upper surface and the lower surface of the substrate and rotated around a first vertical axis, horizontally in synchronization with each other toward an outer peripheral portion of the substrate, and performing a side end cleaning processing in which a third cleaning body is rotated around a second vertical axis and brought into contact with the side end of the substrate to clean the side end of the substrate while simultaneously performing the both-surface cleaning processing.

A window cleaning robot includes a main body including a top shell and a bottom shell. The top shell and the bottom shell define an internal space of the main body and the bottom shell includes a plurality of air inlets. At least two driving mechanisms are disposed between the two driving mechanisms. An air pump is disposed in the internal space and configured to extract air, through the inlets of the bottom shell, between the two driving mechanisms to create negative pressure to form a vacuum area located between the two driving mechanisms. An accommodating portion is configured to accommodate the air pump and an air tube, disposed in the internal space, includes an air inlet end coupled to an opening of the accommodating portion and an air outlet end coupled to an air exhaust opening toward the driving mechanism. The air inlet end of the air tube is configured to receive the extracted air and the extracted air is then exhausted toward the driving mechanism via the air tube and the air exhaust opening.

Disclosed is a central shaft of cleaning roller, including a shaft body and a hollow inner flow channel disposed in the shaft body, and a plurality of dispersed through holes fluidly-communicable with the hollow inner flow channel arranged on an outer wall of the shaft body, and a plurality of groove structures radially extending around the surface of the outer wall of the shaft body, and the groove structures have protruding end edges protruding from the surface of the outer wall. The central shaft of cleaning roller can be used to provide better adhesion for an interface between a foam material and the outer wall thereof.

The present invention relates to a substrate cleaning system and a substrate cleaning method for cleaning a substrate. The substrate cleaning system (50) includes a heater (51), a chemical-liquid diluting module (52), and a cleaning module. A temperature of the diluted-chemical-liquid mixed by the chemical-liquid diluting module (52) is determined to be higher than normal a temperature and lower than a glass transition point of a cleaning member. The cleaning member scrubs the substrate (W) with the diluted chemical liquid having the determined temperature supplied to the substrate (W).

A faucet cleaner is provided. The faucet cleaner includes a supply bottle having a base, a sidewall extending from the base, and a neck. The neck includes a top end having a rim forming an opening into the supply bottle. A delivery cup is secured to the neck of the supply bottle. The delivery cup includes a base and a sidewall extending from the base. The present invention further includes a channel having a bottom end and a top end. The bottom end is disposed in the supply bottle. The channel runs from inside the supply bottle through the opening formed by the rim of the neck, through the base of the pump mechanism and into delivery cup so that the top end is disposed in the delivery cup. A plurality of bristles are secured to the base of the delivery cup and disposed within the delivery cup.

Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.
