In a pressurized cleaning apparatus comprising a pressure generation unit for pressurizing a fluid, in particular for supplying a pressurized fluid via a hose attachment, preferably via a hand-held pistol or a spray nozzle, an operating unit is provided that is designed to make it possible to set a maximum operating pressure of the pressure generation unit at which the pressure generation unit is deactivated.

A self-cleaning barbecue comprising of a built-in power washer system.

A water spray wand comprises an internal water pipe, a spray handle, a compartment for a battery and a light. The spray handle is configured such that when the flow of water is permitted through the spray wand, the electronic communication between the battery compartment and the light is completed, and when the flow of water through the spray wand is interrupted, a timer is activated to interrupt the electronic communication between the battery compartment after a predetermined delay.

A low pressure washer nozzle tip is provided. The low pressure washer nozzle tip has an angled tip with multiple openings and a corresponding retaining nut. The nozzle tip is secured to the retaining nut and wherein both are removably secured to a shaft of a pressure washer gun. The tip of the nozzle is angled at approximately a one hundred to a one-hundred and five-degree axis with respect to a main shaft of the pressure washer.

A nozzle of a spray gun includes an outer part connected to the spray gun. The outer part includes a neck portion formed therein. A neck hole is formed through the neck portion. Multiple paths are defined through the neck portion. The neck portion divides the inner space of the outer part into a first room and a second room. A tube extends through the neck hole and the tube. A swing member is located in the first room and connected to the rear end of the tube. An inner part is located in the second room and connected to the front end of the tube. High pressure fluid is introduced into the first room to swing the swing member. The tube and the inner part swing with the swing member. The high pressure fluid enters into the second room via the paths and spray out from the outer part.

A method for cleaning a paint spray gun, which comprises a rotating atomization head to apply a coating material while rotating and an outer circumferential tube to cover the exterior of the rotating atomization head, has a cleaning solution application step for applying a cleaning solution to the external face of the outer circumferential tube, and a rotating atomization head rotation step for generating a rotational flow between the rotating atomization head and the outer circumferential tube by rotating the rotating atomization head. The cleaning solution flowing down the external face of the outer circumferential tube applied in the cleaning solution application step penetrates between the rotating atomization head and the outer circumferential tube by way of the rotational flow. Such method uses a small amount of cleaning solution for cleaning external and internal faces of the outer circumferential tube and the external face of a rotating atomization head.

The present invention relates generally to the field of pressure washer wands and a cleaning attachment that can be attached to any standard pressure washer wand. The attachment has a roller assembly with a bristled roller head. The head can be positioned in front of the spray tip of a wand such that water that exits the wand and causes the head to spin.

An outdoor surface cleaning apparatus having a handle, a power head with a prime mover, an attachment head having a cleaning attachment, and a spray mechanism. The spray mechanism includes a first fluid input, a second fluid input, a cleaning fluid output, and a mixing assembly. The mixing assembly is in fluid communication with the first fluid input, the second fluid input, and the cleaning solution output.

Retaining bracket for a fluid spray delivery apparatus to ensure that an applicator rod remains properly attached to the apparatus and in fluid communication with the fluid even when subjected to a driving force. Also disclosed is a fluid application system or assembly, and a method of applying fluid using the same, the system or assembly including a source of fluid to be applied to a target object, a siphon gun assembly, an applicator rod, tubing for placing the applicator rod in fluid communication with the siphon gun assembly, and a retaining bracket that secures the tubing to the siphon gun assembly such that the tubing remains in place and does not disconnect from the siphon gun assembly when subjected to a driving force such as water under pressure.

Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.
