A showerhead is provided having a housing, a perforate partition and a nozzle body. The housing has a fluid inlet and a fluid outlet. The perforate partition is provided in the housing between the inlet and the outlet and has at least one peripheral fluid passage communicating with the fluid inlet. Each peripheral fluid passage communicates at a downstream end with an inwardly extending peripheral slot, and each slot communicates at a downstream end with a mixing cavity. The nozzle body is carried by the housing downstream of the mixing cavity and has a compression port at an upstream end and an outlet port at a downstream end in fluid communication with the compression port.

A self-rotating device for cleaning with ultra-high water pressure having a base supported by front and rear wheels with a handle extending therefrom. A spray bar assembly with a plurality of nozzles constructed and arranged to cause rotation of the spray bar through fluid discharge is mounted beneath the base. A hydraulic pump is positioned with spray bar and coupled to a reservoir mounted on the handle. The hydraulic pump is rotated by the spray bar assembly, causing hydraulic fluid to recirculate through the reservoir, wherein an adjustable flow valve permits control of the spray bar assembly rotation speed.

An apparatus includes a moving device movable along the surface of an object, and a rotary nozzle device. A rotary nozzle means comprise a plurality of jet nozzles. Two sets of the rotary nozzle means are arranged in parallel in a direction orthogonal to the moving direction of the moving device, are configured such that a left rotary nozzle means and a right rotary nozzle means perform a rotary motion in association with each other by a rotary transmission means. The jet nozzle of the left rotary nozzle means and the jet nozzle of the right rotary nozzle means are arranged so as to be out of phase with each other.

Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.

A garden sprinkler has an input base, an output member rotatably installed at the top of the input base, and a rotating member capable of driving the output member. The output Both sides of the output member are respectively equipped with a first outlet and a second outlet. The first outlet is equipped with a first sprinkler, and the second outlet is equipped with a second sprinkler and an adjusting sleeve. The second sprinkler is a side outlet and is screwed with the adjusting sleeve. The second sprinkler can be adjusted by the adjusting sleeve, which improves the convenience of sprinkling operation without multiple sprinkler heads.

A sprinkler includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.
