The high-pressure cleaning apparatus also includes a drive unit associated with the valve unit, a control unit coupled to the drive unit and a pressure sensor coupled to the control unit for detecting liquid pressure on the pressure side of the pump chamber. Depending on the signal of the pressure sensor, the liquid pressure can be controllable to a predetermined or predeterminable liquid pressure by changing of the free cross-sectional area of the return line.

The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360° turns to facilitate the treatment of difficult to access portions of the floored surface.

A high-pressure cleaning system is provided, including a high-pressure cleaning apparatus having a high-pressure pump for increasing the pressure of a cleaning liquid, and two or more discharge units for discharging the cleaning liquid, which are different and can be selectively brought into fluid communication with a pump outlet of the high-pressure pump, wherein the discharge units are connectable to an operating unit or wherein an operating unit is arranged on at least one discharge unit. The high-pressure cleaning system includes an input unit via which at least one output parameter is predeterminable by a user and is adjustable by way of a control unit coupled to the input unit. The high-pressure cleaning system includes an output unit coupled to the control unit and capable of providing an indication depending on the predetermination made by the user, said indication including a recommendation of at least one discharge unit.

Disclosed is a two-in-one cleaning apparatus. The two-in-one cleaning apparatus includes a positioning assembly, a booster pump, an automatic hose reel, an intermediate connecting rod, and a spray gun body. The booster pump, the automatic hose reel, the intermediate connecting rod, and the spray gun body are all detachably mounted on the positioning assembly. The booster pump is provided with a water inlet and a water outlet, a water inlet pipe is arranged at the water inlet of the booster pump, and the water outlet of the booster pump is connected to the automatic hose reel. The automatic hose reel is provided with a mounting bracket, the positioning assembly is provided with a positioning support plate matching the mounting bracket, and the automatic hose reel is mounted on the positioning assembly through matching between the mounting bracket and the positioning support plate. The spray gun body is detachably connected to the booster pump and the intermediate connecting rod, respectively. The disclosure has the beneficial effects of being convenient to carry, high in stability, wide in application range, capable of meeting different use requirements, convenient to dismount and mount, simple in structure and convenient to operate.

Integrated probes and probe systems suitable for attachment to a robotic arm of a remotely operated vehicle are disclosed. The probes and probe systems serve to perform cleaning operations and both cathodic protection (CP) voltage measurements and ultrasonic testing (UT) thickness measurements at an underwater surface. The cathodic protection measurement system includes one or more electrically conductive legs that extend outwardly from the probe. These legs are arranged about a cleaning tool and an ultrasonic sensor. When the integrated probe contacts the underwater surface, at least one leg contacts the surface, thereby providing a desired distance between the probe and the underwater surface for efficient cleaning and UT inspection. The underwater surface can be cleaned and CP and UT measurements can all be performed using a single, integrated probed during a single operation, without having to reposition the probe.

The window cleaning robot according to the invention has an artificial intelligence-controlled moveable washing system which senses such projections as frames, moldings, composite coating materials, etc. on the facades by means of the sensors disposed thereon and which adjusts the positions of the cleaning brushes in a way to contact with the glass surface evenly. It makes the facade cleaning in high-rise buildings safer with the fans adjusting the axial thrust force according to the speed and direction of the wind in a way not to detach from the surface to be cleaned. It allows saving on time, labor force, and costs in facade cleaning. The robot permits performing the cleaning in glass surfaces and facades in a safe manner eliminating the requirement of human factor.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.

A controller associated with a machine may determine that a first subset of nozzles, of a plurality of nozzles of the machine, is to be cleaned. The controller may determine a first flow rate of the fluid through the first subset of nozzles and increase, based on determining that the first subset of nozzles is to be cleaned, the first flow rate of the fluid through the first subset of nozzles to a second flow rate of the fluid through the first subset of nozzles. The controller may decrease the second flow rate of the fluid through the first subset of nozzles to the first flow rate of the fluid through the first subset of nozzles when the first subset of nozzles is cleaned.

The steps of providing a cleaning device, a liquid proportioning device and a series of tanks filled with liquids. The cleaning device has a nozzle, a series of hoses and a pump. The liquid proportioning device includes a series of passageways, having three chambers and two valves, and a manifold for mixing the liquids to form a cleaning solution. The passageways include knobs to set the ratio of each liquid that the user desires to mix into a cleaning solution. Once the cleaning solution is mixed, it is fed through a pump to cleaning device for use. The proportioning device allows a user to easily, quickly and accurately mix liquids to form a cleaning solution.
