The present invention discloses a 3D positioning apparatus for an underwater high-pressure water decontamination nozzle, which comprises a variable length water gun, a high-pressure water nozzle fixed to a front end of a gun barrel of the variable length water gun by a nozzle quick lock, and a high-pressure water intake pipe connected to a rear end of the gun barrel, the gun barrel being fixed to a gun body by a water gun quick lock, and further comprises an underwater sonar 3D positioning unit arranged on the gun body, The underwater sonar 3D positioning unit comprises a sonar signal generator, a power amplifier, a sonar having one transmitting unit and three receiving units distributed equidistantly along a circumference thereof, a signal amplifier, a distance identification and correction module, a temperature and salinity measurement module, and an alarm apparatus in circuit connection.

The present invention relates to a handheld high-pressure cleaning machine, including: a main machine housing, allowing detachable attachment of a battery pack, where the main machine housing includes a main body portion; a liquid outlet; a first handle; a motor; and a pump, where a battery pack mounting portion includes a first battery pack mounting portion and a second battery pack mounting portion, and the battery pack includes a first battery pack and a second battery pack; and the first battery pack mounting portion and the second battery pack mounting portion are respectively disposed on left and right sides of a middle plane in a manner that a distance W2 between a leftmost edge of the first battery pack mounting portion and a rightmost edge of the second battery pack mounting portion is not greater than a width W1 of the main body portion.

The wall-climbing pressure washing tool is configured for use in washing a wall. The wall-climbing pressure washing tool transports a liquid under pressure to the wall. The wall-climbing pressure washing tool diverts a portion of the received liquid to generate a motive force that moves the wall-climbing pressure washing tool along the wall. The wall-climbing pressure washing tool comprises a pressure head and a telescopic handle. The pressure head is the working element of the wall-climbing pressure washing tool. The pressure head diverts a portion of the liquid to a motive device that moves the pressure head along the wall. The pressure head transports the balance of the liquid to the wall. The telescopic handle manipulates the wall-climbing pressure washing tool. The span of the length of the telescopic handle adjusts as the pressure head moves along the wall.

A pressure washing assembly includes a fluid fitting that is fluidly coupled to a fluid source. A spraying tube is removably coupled to the fitting to receive a fluid from the fluid source. The spraying tube sprays the fluid for cleaning an object. A handle is coupled to and extends laterally away from the spraying tube for gripping to enhance manipulating the spraying tube. An elbow fitting is removably attachable to the fluid fitting to receive the fluid from the fluid source. A fluid hose that a similar size with respect to the spraying hose can be attached to the elbow fitting to deliver the fluid to the fluid hose.

A portable unit having a lance incorporating a steam generator and a sanitizer tank, which can improve the sanitizing and disinfection of surfaces with steam, and having a set of lines and power supply cable and a human-machine interface, which enables the supply of the fluids and electrical energy either in situ on any local network that has a water and power supply and a centralized air-blowing/suction device, or on a user-portable module that incorporates autonomous arrangement for managing the fluids and electricity.

In order to clean large surface areas using one device a stream of air or water is directed through a rigid tube and exits from a plurality of holes on a pair of sweeper arms that are connected to the rigid tube. Flexible joints are provided on the sweeper arms in order to allow the sweeper arms to bend. Bushings that are connected together permit the operation sweeper arms to be moved from side to side.

A liquid dispensing device for a high pressure cleaning device is provided, and includes a liquid inlet, which is connectable to a pump outlet by a pressure conduit, a liquid outlet, an input apparatus, a display apparatus, and a control unit including a storage member in which control parameters are storable, and wherein at least one control parameter can be output from the control unit to the high pressure cleaning device. In order to further develop the liquid dispensing device to enable an improved cleaning result in a simple manner, the liquid dispensing device includes an object detection unit for contactlessly detecting the object to cleaned, wherein object information corresponding to the object to be cleaned is transmittable from the object detection unit to the control unit and is processable thereby for providing at least one control parameter adapted to the object to be cleaned.

A cleaning device includes a cartridge assembly, a hose/tubing, a nozzle, and an activator. The cartridge assembly includes at least one cartridge configured to hold a liquid solution. An attachment device is coupled to the cartridge assembly and is configured to secure the position of the cartridge assembly to a user's arm adjacent the hand. A pump is located within the cleaning device and is located between cartridge and the nozzle, such that pump regulates dispensing of the liquid solution. The nozzle is in communication with the pump and acts as a diffuser to adjust the stream of the liquid solution passed through the hose from pump. The activator is in communication with the pump such that operation of the activator selectively releases a volume of the liquid solution from the cartridge so as to pass through the nozzle. A control unit and interface are permitted.

A wand apparatus for controlling a pressure washing system and an associated method for controlling a pressure washing system is provided. The wand apparatus may include a first wand portion and a second wand portion. The wand apparatus may further include a chemical control assembly that includes a housing and a chemical control element. The housing defines an outlet aperture, an inlet aperture, and a chemical control aperture. The chemical control aperture is configured to operably engage the chemical control element. The outlet aperture is configured to operably engage the first wand portion, and the inlet aperture is configured to operably engage the second wand portion. Further, operable engagement of the chemical control element may provide for switching the wand apparatus between a chemical spray configuration and a wash spray configuration.

A method of removing material from a surface of a workpiece includes discharging a flow of fluid towards a workpiece at a pressure and a flow rate that facilitates forming a plurality of cavitation bubbles, and introducing abrasive media. The method includes exciting the abrasive media with the cavitation bubbles, removing material from the workpiece by an interaction between the cavitation bubbles and the abrasive media, and the surface of the workpiece.
