A working machine may be provided with: a case configured to store water therein; and a working machine body configured to discharge water supplied from the case, in which the working machine body is detachably mounted on an upper surface of the case.

An oral cleaning device according to the disclosure includes a body unit including a pump configured to discharge washing liquid, a tube connected to the body unit to allow the discharged washing liquid to flow through the tube, a washing unit connected to the tube to discharge the washing liquid, a first operation part provided at the washing unit, a controller configured to control the pump in accordance with operation of the first operation part, and a communication unit configured to establish a communication connection between the first operation part and the controller.

A paint removal apparatus for cleaning paint from masking devices includes a support base having a plurality of engagement features that are each configured to securely engage at least one paint masking device. A spray nozzle is aimed in a fixed direction toward the support base and configured for spraying a pressurized stream of water at a desired velocity that removes paint from an exterior surface of at least one of the masking devices engaged at the support base. The support base is configured to successively move the masking devices engaged at the engagement features into the pressurized stream of water, such as to provide a generally continuous cleaning operation of masking devices. During movement or rotation of the support base, an exposed portion of the support base may extend from a spray enclosure for removing cleaned plugs from and loading painted plugs onto such an exposed portion.

A machine for treating a medical apparatus, such as an endoscope washer-disinfector, can be integrated into a wall at an opening of the wall. The wall can separate a first enclosure with a controlled/non-controlled atmosphere from a second enclosure with a non-controlled/controlled atmosphere. The machine may include first and second openings configured to allow the medical apparatus to be loaded into/unloaded from the machine. The machine may also include first and second doors sealingly closing the openings. The machine may include a partitioning interface attached to the wall that closes the opening in the wall and a movable part that can be removed from the partitioning interface. The movable part can at least partially carry a pump and solenoid valve of the treatment system. The movable part can be positioned immediately adjacent to the partitioning interface when the treatment machine is in an operating position.

A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

According to an implementation, a pressure washer system may include a pump and an engine drivingly coupled with the pump. A pressure washer controller may be associated with one or more of the pump and the engine. A battery may be communicatively coupleable with the pressure washer controller for one or more of receiving data from the pressure washer controller and transmitting data to the pressure washer controller. The battery may include a memory module for storing one or more of data received from the pressure washer controller and data to be transmitted to the pressure washer controller.

A hand-held high-pressure cleaning machine includes: a housing, having a handle for grasping; functional components, including a motor and a pump driven by the motor; and a liquid inlet, disposed on the housing and capable of being connected to an external water source by a water pipe. The hand-held high-pressure cleaning machine further includes an adapter suitable to be connected between the liquid inlet and a portable container, and is connected to the external water source by the water pipe or connected to the portable container by the adapter. In the present invention, the portable container configured to hold liquid is mounted to the hand-held high-pressure cleaning machine by using the adapter, so that it can be flexibly moved together with the hand-held high-pressure cleaning machine. The present invention further provides an adapter suitable to be connected between a portable container and a hand-held spraying device.

A pressure washer includes a water pump, a spray gun fluidly coupled to an outlet of the water pump, an electric motor coupled to the water pump to drive the water pump, a battery module configured to provide battery electricity, an electrical plug configured to receive grid electricity from a power outlet, and a power management system electrically connected to the battery module, the electrical plug, and the electric motor. The power management system is configured to selectively provide battery electricity from the battery module and grid electricity from the electrical plug to the electric motor to drive the water pump.

A variable pressure sprayer is provided having a housing on which is mounted a battery, a battery-operated motor, and a motor-operated liquid pump, a tank communicating with the pump for holding a supply of liquid, a liquid outlet from the pump to a connector adapted to receive a hose, and an applicator wand adapted for connection to the hose for directing fluid under pressure to a desired target. A trigger is positioned on the applicator wand adapted to switch between a closed flow position and an open flow position. A variable pressure controller is positioned on the housing and connected to the motor for varying output pressure percentage of the pump.

An electric power washer contains a main body having a pump and an electric power source, a hose, a handle, and a control circuit. The hose contains a first end fluidly-connected to the pump and a second end fluidly-connected to the handle, which has a button operatively-connected to the control circuit, which is operatively-connected to the pump and the electric power source. The control circuit controls the pump output and contains a timer. The control circuit permits the pump to normally operate at up to 100% normal power. However, when the button is activated, the control circuit permits the pump to operate at a boost power mode of from about 103% normal power to about 300% normal power. The control circuit intermittently pulses the boost power mode and terminates the boost power mode after a predetermined period of time or when the button is no longer activated, whichever is shorter.
