A hydroblaster includes a carriage. A plurality of bearings is rotatably mounted to the carriage at a bottom portion of the carriage. A plurality of legs is mounted to the carriage at the bottom portion of the carriage. The plurality of legs extend downwardly from the bottom portion of the carriage past the plurality of bearings. A fluid conduit is disposed on the carriage at a top portion of the carriage. A first motor is mounted to the carriage at the top portion of the carriage. The first motor is coupled to the fluid conduit such that the first motor is operable to rotate the fluid conduit. A second motor is mounted to the carriage at the top portion of the carriage. The second motor is coupled to a gear positioned at the bottom portion of the carriage such that the second motor is operable to rotate the gear.

The disclosure includes a watercraft cleaning system that includes a housing, a water input line, a pump and motor system, a high-pressure output line, and a heater. The cleaning system can be arranged and configured to be coupled to a dock post located adjacent a watercraft. The system can easily and conveniently allow watercraft personnel to clean the watercraft.

A filter cleaning system with a cleaning chamber. The cleaning chamber has a container, a plurality of shafts and a plurality of nozzles inside of the container, and an outlet. The shafts extend along a length of the cleaning chamber and are configured to support a cylindrical filter. Each of the shafts is rotatable with respect to the chamber and is configured to cause the filter to rotate about an axis of the filter. The nozzles are positioned below the shafts and are configured to spray water upward toward a gap between the shafts. Each nozzle has a spray pattern comprising a flat fan pattern with a centerline. Each nozzle is oriented such that the centerline is nonparallel with the axis of the filter. The outlet is configured to drain recovery water out of the interior of the cleaning chamber.

In one embodiment, a cleaning and drying module includes a process rotor having grip pins for holding a substrate. The process rotor rotates and moves between lowered and raised positions. A plurality of sweep arms each have a nozzle mechanism to apply a cleaning and/or drying fluid to the substrate. A collection rotor rotates synchronously with the process rotor. The collection rotor includes a collection weir defined by a bottom portion of the collection rotor and the inner surface. The collection weir collects fluids and particles from the process rotor and the substrate. Drain holes are positioned in the collection weir to drain fluids and particles from the collection weir. A rotor cover surrounds and extends above the sidewall of the collection rotor defining an annular volume between the rotor cover and the collection rotor. An exhaust draws air through the drain holes and receives the collected fluids and particles.

A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.

A portable power washer. The portable power washer includes a housing. The housing is made of a flexible material and includes a base, a sidewall, an opening, and a lid openably and closably coupled the sidewall and covering the opening. A hose coupler fluidly connects an inside of the housing with an outside of the housing. A pump is operable to pump a liquid from the inside of the housing and through the hose coupler.

The present invention relates to a cable machine and jet line combination device primarily comprised of a frame with at least one wheel, at least one spool with at least one hose, at least one spool with a snake auger, at least one motor, and at least one pump. The hose of the first spool is preferably a jetter hose that can be used to flush a sewer line. The water pressure within the hose can be increased by the pump which is powered by the motor. The snake auger can be used to further clean sewer lines of debris.

A substrate cleaning apparatus includes a stage on which a substrate is placed, a support unit configured to support the substrate and to rotate the substrate, and a cleaning unit configured to spray a dual fluid to clean the substrate, wherein the cleaning unit may include a spray nozzle including a spray hole opened toward the stage and configured to spray a dual fluid through the spray hole, a cover that may include an inlet surrounding at least a partial area of an outer circumferential surface of the spray hole, that may surround at least a partial area of an outer circumferential surface of the spray nozzle, and that may be spaced apart from the spray nozzle by a predetermined distance, and an air flow passage formed in a space between the cover and the spray nozzle and through which air sucked from the inlet flows.

A washing apparatus includes: a housing; a holding part that holds a substrate arranged in the housing; a washing nozzle that supplies a washing liquid to the substrate held by the holding part; a gas nozzle that ejects a gas toward a ceiling of the housing; and a control part that controls the gas nozzle.

A high-pressure washer has a housing and an actuator rotatably supported about an actuator rotation axis. A control element is arranged rotatably at the housing and is provided to control the actuator. The control element and the actuator are fixedly connected to each other for joint rotation by one or more universal joints.
