A washing device includes a motor having a shaft, a battery electrically connected to the motor, and a pump driven by the motor. The pump is adapted to pressurize a liquid. The pump is disposed on the motor so that the motor is disposed between the pump and a ground.

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 machine with a cleaning system and a tugging system. The cleaning system can include a floor cleaning feature configured to dispense a cleaning solution onto a floor surface, agitate the cleaning solution, and remove the cleaning solution from the floor surface. The cleaning system can include an onboard cleaning solution tank, an onboard recovery tank, and an onboard vacuum. The tugging system can include a hitch coupled to a front end of the machine and can be configured to tow an airplane.

Ladder cleaning device, particularly for use on ladders mounted on offshore installations, wherein the ladder cleaning device comprises: means for guiding and moving the device along the ladder means for detecting a ladder rung means for cleaning at least the detected rung.

A frame for a pressure washing device is provided. The frame comprises at least one tubular member and a plurality of bends are provided in the tubular member. The frame is preferably devoid of a support plate and is adapted to receive at least one of a power source and a pump that is directly mounted to the frame.

The notched base ring comprises a base ring sheet body including a top portion, a bottom portion, a first end connecting the top portion to the bottom portion, and a second end connecting the bottom portion to the top portion. The top portion includes a plurality of attachment lugs and defines a plurality of notches, each notch being at least partially defined by two lugs disposed on opposite sides of the notch, the top portion also including an angled top edge that is disposed at each of the attachment lugs, and the bottom portion includes a bottom support edge.

Provided is a pump apparatus capable of suppressing an unintentional ejection of a high-pressure liquid from a nozzle. A pump apparatus including: an injection chamber having a door; a nozzle arranged in the injection chamber; a pump connected to the nozzle for discharging liquid; a motor for driving the pump; a door sensor for detecting that the door is closed; and a control device capable of communicating with the door sensor, the control device having a motor rotation unit for supplying driving power to the motor only when the door sensor detects that the door is closed.

A mobile surface maintenance machine embodiment includes a mobile body, a solution tank for containing a cleaning fluid, wheels for supporting the mobile body, a maintenance tool(s), an output channel, an electric power source, a first electric motor, and a pressure washer. The pressure washer includes a spray wand, a pressure pump, and a second electric motor. The pressure pump is fluidly coupled to the spray wand and to the solution tank. The pressure pump is configured to pressurize the cleaning fluid supplied to the spray wand. The second electric motor is operatively coupled to and configured to drive the pressure pump. The second electric motor is configured to receive electric power from the electric power source and is commonly powered by the electric power source that provides power to the first electric motor. The second electric motor is separate from the first electric motor.

A shellfish basket washing apparatus configured to hang over the side rail of an oyster harvester or other boat having a support assembly arranged to straddle and be supported on said side rail, a basket holder and a high pressure nozzle assembly connected to a water side of said support assembly, and a working platform, including a pressure washer pump and a water tank, connected to an onboard side of said support assembly.

A self-cleaning condensate drain pressure trap for air conditioning is defined here comprising; a modified pressure trap and assembly; a primary condensate flow path through the pressure trap assembly; a fluid reservoir which prevents the transmission of air through the pressure trap; a fluid pumping flow path from the upper pressure trap to the lower pressure trap reservoir; a fluid pump coupled to the fluid pumping path; a control board coupled to the fluid pump, connector cable and fluid sensor; an outer protective cover for the assembly. The control boards unclogging mode is actuated by wet sensor, monitoring mode by dry sensor. Unclogging mode suspends air conditioner operation, energizes the fluid pump to pump condensate into the reservoir, whereby reservoir clogs are broken down. Where a pressure trap clog causes a high accumulation of condensate, a broken-down clog allows accumulated condensate to flow through and flush it out.
