The embodiments of the present disclosure disclose a drone-based cleaning method and system, wherein the method includes: flying to a designated position of an object to be cleaned when the drone receives a cleaning instruction for cleaning the object to be cleaned, determining a cleaning area corresponding to the designated position on the outer surface of the object to be cleaned, obtaining environmental information of the cleaning area, controlling the cleaning device of the drone being flipped from below to a position parallel to the outer surface according to the environmental information, and controlling the cleaning device to clean the cleaning area, so that the drone can be more intelligently controlled for cleaning, making it safer to clean the exterior walls of objects.

A robotic device for providing vertical mobility has a payload disposed inside a central compartment and can move up and down through spring load to keep intimate contact with the surface and cross over bumps. The apparatus uses a flexible seal to create a reliable vacuum chamber. The flexible seal comprises a foam ring inside fabric pocket. A plurality of rod and spring strips are configured to apply a downward force to the flexible seal to conform with surface curvatures. The fabric pocket fills in the gaps or seams to maintain a vacuum. The air flows inside a manifold and passes through a filter to avoid debris from damaging the vacuum motor assembly.

A reconfigurable surface cleaning apparatus has a removable portable surface cleaning unit wherein the portable surface cleaning unit has upper and lower longitudinally spaced apart mounting members.

A reconfigurable surface cleaning apparatus has a surface cleaning head, a support structure moveably mounted to the surface cleaning head between a storage position and a floor cleaning position and a portable cleaning unit removably mountable to the support structure. The support structure has a pair of laterally extending portions and the portable cleaning unit has a first mounting member comprising mating grooves which slideably receive the laterally extending portions when the portable cleaning unit is mounted to the support structure.

A robotic device that can adhere to the surface of an object by negative-pressure suction and that can travel in a Y-axis direction and an X-axis direction. The robotic device is equipped with four suction cup units, Y-axis actuators and X-axis actuators. As for the planar shape of each suction cup, it has a shape of each quadrangle when a roughly square was divided into four quadrangles of the same shape. The quadrangles are formed provided with two right-angle portions in a diagonal portion. One right angle of the two right-angle portions of each suction cup overlaps with one of the four right angles of the square. Two of the sides that constitute the above right angle of the suction cup overlap with two of the edges that constitute the above right angle of the square. One of the sides that constitute another right angle of the suction cup intersects to an acute angle in one side of the right angle of the square, and another side intersects to an obtuse angle in another side of the right angle of the square.
