A system and method for accessing contents of a tank through a tank opening disposed on the tank. The system and method may obtain samples, use a sensor to analyze sludge or may clean the tank. The system has a rotatable head connected to a rigid tube having a central axis. The rotatable head is adapted to be inserted through the tank opening. The rotatable head comprises a displacer and a head opening. A flexible tube has an insertable end and an external end. The flexible tube is slideably movable within the rigid tube and has a range of motion relative to the rigid tube so that the insertable end of the flexible tube can be directed by the displacer through the head opening at an angle offset from the central axis of the rigid tube.

A pressure washer includes a main line through which, via a high-pressure pump, liquid can be conveyed to a spray opening, and a main valve. The main valve, when in a closed state, prevents liquid from flowing through the main line and, when in an open state, allows liquid to flow through the main line. The main valve is switchable between open and closed via an operator-controlled element. The main line has a suction chamber between the connection and the pump and a pressure chamber between the pump and the spray opening. The pressure chamber is fluidically connected to the suction chamber via a bypass line. A free cross-sectional area of the bypass line is settable via a bypass valve in the bypass line for regulating pressure in the pressure chamber. The bypass valve is adjustable via the operator-controlled element for setting the free cross-sectional area of the bypass line.

A system for and method of removing residues, deposits, and debris from a substrate that has been marked by a chemical etching process is disclosed. The system includes one or more upper sprayers that deposit a cleaning solution to a top surface of the product as it passes beneath the one or more upper sprayers. The system further includes at least one upper brush that operates to scrub the top surface of the product after the cleaning solution has been applied thereto. The system optionally includes one or more lower sprayers and lower brushes to clean a bottom surface of the product as it is conveyed through the system. The system further includes an air knife system that assists with drying the product prior to exiting the system. The system further includes a controller that is operable to adjust various system parameters.

A cleaning device for removing contamination on a substrate holder used with an electroplating cell includes an arm, a cleaning agent supplier, a nozzle and a receiver. The cleaning agent supplier is coupled to the arm and configured to supply a cleaning agent. The nozzle is coupled to the cleaning agent supplier and configured to spray the cleaning agent onto the substrate holder to remove the contamination. The receiver is coupled to the arm and configured to receive the cleaning agent after the cleaning agent is sprayed onto the substrate holder.

A tool cleaning station may include a housing. The housing may comprise a first end and a second end; an interior space; a tool aperture disposed between the first end and the second end and in communication with the interior space; a fluid aperture in fluid communication with a fluid source and in communication with the interior space; and a drainage aperture in communication with the interior space. The station may also include a first brush rotatably disposed in the interior space and secured between the first end and the second end and the first brush may have a first axis. The station may also include a second brush rotatably disposed in the interior space and secured between the first end and the second end and the second brush may have a second axis parallel to and offset from the first axis.

A grout cleaning device is disclosed herein. The device comprises a cover, a connector configured on an operative top surface of the for facilitating secure connection of a pressurized water dispenser thereon. There is also an adaptor attachable to the connector for being in fluid communication with the pressurized water dispenser. The adaptor is configured for directing a jet of water from the pressurized water dispenser on a grout slit requiring cleaning. Additionally, there is a suction attachment disposed within an interior space defined by the cover for sucking a slurry of dirt and water resulting from the cleaning of the grout slit.

Disclosed is a method for liquid-treating a substrate. In a method for treating a substrate, the substrate may be treated by supplying a treatment liquid onto the rotating substrate by using a first nozzle and a second nozzle, the first nozzle supplies the treatment liquid to an area including a central area on the substrate, and the second nozzle supplies the treatment liquid to a peripheral area of the substrate.

The invention relates to a device for cleaning the surface of a tool for shaping the surface of a large-area fiber composite material body using a highly pressurized cleaning liquid, having a nozzle support which is held on a central bearing in a rotatable manner, at least one jet nozzle which is held in an arm of the nozzle support and out of which the highly pressurized cleaning liquid exits during operation, and a control unit for controlling the cleaning liquid pressure to be applied, wherein the nozzle support is surrounded by a housing which is provided with an opening towards the tool surface to be cleaned. The housing is connected to a suction device by means of which a housing interior equipped with the nozzle support can be suctioned. The housing interior is connected to an outer surrounding area via a pressure valve, and a liquid-tight seal with a flexible shape is arranged on a housing end which forms the opening, wherein the seal can be used to seal the space between the nozzle support and the body surface to be cleaned from the outer surrounding area, and the control unit has at least two pressure range settings. The invention additionally relates to a method for cleaning a surface of a tool.
