The present invention relates to an apparatus for cleaning a surface, in particular at solar collectors or photovoltaic installations. The apparatus has at least one cleaning head that comprises at least one cleaning member. The cleaning member is in particular a brush that can be set into rotation. The apparatus furthermore has a movement device for moving the cleaning head over at least a part of the surface to be cleaned. The movement device has a first movement unit movable in a first direction and a second movement unit. The cleaning head is movable transversely or obliquely to the first movement direction by means of the second movement unit along a guide means that is connected to the first movement unit. A control means that is arranged at the first and/or second movement units makes it possible to automatically move the first movement unit in dependence on a position of the second movement unit.

A robotic device for working on a surface includes a body including: a tool for working on the surface; a controller moving the body along the surface; a first set of at least two rotors mounted to the body and generating thrust in a first direction towards the surface; and a second set of at least two rotors mounted to the body and generating thrust in a second direction away from the surface. A sensor measures a distance between the body and the surface, and a computer adjusts the first set of rotors and the second set of rotors in response to the sensor to place the body in position to work on the surface. In particular, the first set of rotors and the second set of rotors generate a net force on the body to it in non-contact position to work on the surface.

Provided are a structured light module and an autonomous mobile device. A structured light module comprises a camera module and line laser emitters distributed on two sides of the camera module; the line laser emitters emit line laser outwards; and the camera module collects an environmental image detected by the line laser. By virtue of the advantage of high detection accuracy of the line laser, front environmental information may be detected more accurately. In addition, the line laser emitters are located on two sides of the camera module. This mode occupies a small size, may save more space, and is beneficial to expand an application scenario of a line laser sensor.

A vertical surface cleaning device comprising a main body, a cleaning arm, a cleaning head, and leg mechanisms with grippers. The cleaning head applies a cleaning fluid on a surface to carry out a cleaning operation. A waste collector is provided to collect a waste material arising from the cleaning operation. The grippers may remain in a grip or in a release state. The segments of the leg mechanisms are articulatable to configure a first group of the leg mechanisms to stably hold the main body at a first place with the grippers remaining in the grip state. A second group of the leg mechanisms move in a desired direction with their grippers in release state while the first group stably holds the main body. The first group of the leg mechanisms then moves in the same direction while the second group holds the main body at a second place.

The invention belongs to the devices for automatic cleaning and ventilation of windows from the facade of high-rise buildings. The technical result of the proposed invention is the simplification of the construction of the device, which makes it possible to clean the glass surface without human resources, which is also financially profitable. In this case, the glass cleaning, which is carried out by a climber and costs from 7 to 28 dollars per square meter, is reduced to 1 dollar per square meter through the proposed invention. The essence of the invention lies in the fact that the proposed device contains an additional washing solution valve equipped with pipes, ventilation box, ozonator, filters, speakers and control panel, water valves, as well as a water valve with a flushing solution for the pipe. In the first section of the frame, the water valve is also connected to the outlet pipe.

An automated building washing device generally includes a spray bar assembly coupled to a window washing swing stage. The spray bar assembly is horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while spray heads rotate so that a relatively large portion of building surface can be quickly cleaned. The spray bar assembly includes a hollow rotating bar and spray heads inside of a shroud so that the bar can rotate as water or cleaning solution is sprayed onto the building surface for cleaning.
