A billiard table cleaning device for autonomous cleaning of a playing surface of a billiard table includes a housing, which defines an interior space and which has at least one linear side. A drive unit is engaged to a bottom of the housing and is configured to selectively motivate the housing across a playing surface of a billiard table. A vacuum assembly is engaged to the housing and is positioned in the interior space. The vacuum assembly suctions air and debris, such as chalk dust, through slots positioned in the bottom and expels filtered air through vents positioned in or proximate to a top of the housing, thereby cleaning the playing surface.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

Provided is a method, computer program product, and system for leveraging spatial scanning data of an environment collected by a robotic vacuum to generate recommendations for improving environmental conditions. A robotic vacuum may collect cleanliness data relative to an environment. The robotic vacuum may store the cleanliness data over a plurality of cleaning cycles. The robotic vacuum may analyze the cleanliness data over the plurality of cleaning cycles to identify one or more cleanliness trends. The robotic vacuum may generate a recommendation for improving an environmental condition relative to the environment based on the identified one or more cleanliness trends. The robotic vacuum may provide the recommendation to a user.

Provided is a robot including: a chassis; wheels; electric motors; a network card; sensors; a processor; and a tangible, non-transitory, machine readable medium storing instructions that when executed by the processor effectuates operations including: capturing, with at least one exteroceptive sensor, a first image and a second image; determining, with the processor, an overlapping area of the first image and the second image by comparing the raw pixel intensity values of the first image to the raw pixel intensity values of the second image; combining, with the processor, the first image and the second image at the overlapping area to generate a digital spatial representation of the environment; and estimating, with the processor using a statistical ensemble of simulated positions of the robot, a corrected position of the robot to replace a last known position of the robot within the digital spatial representation of the environment.

Embodiments of the present disclosure disclose a mounting bracket and a self-propelled robot. The mounting bracket includes a housing, a rotating shaft and a magnetic positioning assembly. The housing is provided with an inner cavity. The rotating shaft is configured to rotate about an axis in the inner cavity. The magnetic positioning assembly includes a first magnetic element and a second magnetic element which are respectively arranged on the housing and the rotating shaft. The laser distance sensor is attached to the rotating shaft and configured to rotate about the axis. The mounting bracket is configured to prevent the rotating shaft from deviating from the axis by generating a force between the first magnetic element and the second magnetic element in a radial direction of the rotating shaft.

A robotic cleaner may include a suction motor, a dust cup, and a suction motor air duct fluidly coupled to the suction motor and the dust cup. The suction motor air duct may include a debris barrier having a restricting region and a guard region.

A cleaner includes a body including an insertion slot facing a floor and an installation space inside the body. The cleaner includes a dust housing detachably connected to the body. The dust housing includes a collection opening surface and a storage space that stores foreign substances collected through the collection opening surface. The cleaner has an agitator rotatably connected to the dust housing and exposed through the collection opening surface. The cleaner also includes a driving apparatus that rotates a driving coupler, which drives a driven coupler coupled to the agitator. The cleaner includes a lever located on either the driving coupler or the driven coupler. The lever selectively attaches or separates the driving coupler and the driven coupler. Manipulating the lever separates the driving coupler and the driven coupler and allows the sweep module including the agitator to be removed through the insertion slot in the body.

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.

A robot cleaner having a fan brake device is provided, which includes a main cleaner body having an accommodating slot used to contain a dust box and a fan, and at least one brake device is disposed inside the accommodating slot. The brake device is disposed at a notch on the bottom of the dust box for the fan to be inserted into, and under the junction line between the notch and the bottom edge of the dust box. Therefore, when the dust box is taken off from the main cleaner body, the flexible element of the brake device can press a soft stopper upward and then the soft stopper presses against the bottom of the fan blade of the fan to stop the fan.

A wheel includes: a hub; and a running wheel body, which includes a tread on an outer periphery thereof. The tread includes segments. The segments are essentially planar. First segments of the segments are inclined toward one end face of the running wheel body and second segments of the segments are inclined toward an other end face of the running wheel body.
