A driving mechanism for an autonomous planar surface cleaning robot is disclosed. The driving mechanism includes a first transmission component and a second transmission component spaced apart in parallel relationship relative to the first transmission component. Each of the first and second transmission components defines first and second ends and first and second sides, wherein the first sides face each other and the second sides face away from each other in a direction transverse from the direction of motion and the first and second ends are oppositely spaced along the direction of motion. Each of the first and second transmission components are independently controllable by a control unit of the autonomous planar surface cleaning robot.

The present invention discloses a high flow low pressure suction device. The device is a non-contact suction device based on multiple stage turbulence based low pressure suction mechanism which comprises fan(s) or rotating impeller(s) for drawing air/fluid/slurries operates without any seal between the device and the sucked surface. The device compounds this turbulence based low pressure generation along with Bernoulli's principle to yield a high efficiency suction device. The device implements the above concept by making the air/fluid/slurries flow through two or three zones selected from the acceleration zone(s), turbulence zone(s) (high turbulence zone) and smooth zone(s) (minimum turbulence zone). The device works by pulling the air/fluid/slurries into the vacuum chamber, accelerating the air/fluid/slurries, creating turbulence in the air/fluid/slurries in a thin region near the perimeter in order to cause a drop in pressure and then maintaining pressure over a large bottom area and finally exhausting the air/fluid/slurries through the fan(s)/rotating impeller(s).

A multimedia intelligent cleaning system and a control method thereof may include a self-propelled cleaning robot for cleaning a working surface and a safety guard device for connection with the self-propelled cleaning robot. The self-propelled cleaning robot and the safety guard device are detachably connected with each other through a securing assembly. The securing assembly has a first state in which the safety guard device is connected with the self-propelled cleaning robot and a second state in which the safety guard device is separated from the self-propelled cleaning robot. The multimedia intelligent cleaning system further comprises a detection assembly for detecting whether the securing assembly is in the first state or the second state, and a control unit for controlling whether the self-propelled cleaning robot enters a safe activation state depending on a detection signal from the detection assembly.

A popcorn eliminator device used to remove the popcorn design from the ceilings is disclosed. A popcorn eliminator device for scraping and cleaning comprises a vacuum head, a main scraper blade, a front scraper blade, an adaptor, a plastic collection tube and a connection hose and a shop vacuum. The adaptor connects the plastic collection tube using a connection hose to a heavy-duty shop vacuum. The popcorn eliminator device is flipped over and applied to the ceiling using a pushing motion and the front scraper blade is pressed into the slot in the front lip of the vacuum head, thereby scraping near the wall at the end of each pass. The popcorn eliminator device simultaneously collects the debris in the vacuum head resulting in the intake of debris by the vacuum.

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.

A popcorn ceiling scraper includes a scraping head with multiple blades, at least one of which is oriented horizontally in the same plane as the scraping head with other blades extending vertically from the scraping head. The ceiling scraper has a funnel arranged below the scraping head, and the funnel and the scraping head are formed to reach to an edge or juncture between a ceiling and a wall.
