Abstract: A method for operating a cleaning appliance, which moves automatically inside a surrounding area, wherein the cleaning appliance performs a cleaning of a defined spatially defined partial surface area of the surrounding area. To optimize the cleaning operation as a function of a measured soiling, it is proposed that a detection device of the cleaning appliance measures a level of soiling of the partial surface area during the cleaning of the partial surface area, wherein the level of soiling is compared to a defined reference level of soiling and wherein the partial surface area is enlarged automatically by adding a defined additional partial area, which adjoins the partial surface area, if a level of soiling above the reference level of soiling is determined inside the partial surface area.

Abstract: A mobile cleaning robot system can include a mobile cleaning robot and processing circuitry. The mobile cleaning robot can include a camera and can be operable to clean a floor surface of an environment. The processing circuitry can be in communication with the mobile cleaning robot and the camera, the processing circuitry configured to produce an image output based on an optical field of view of the camera. The processing circuitry can also detect a visual fiducial in the image output and can determine a behavior modification based on the visual fiducial. The processing circuitry can modify movement of the mobile cleaning robot based on the behavior modification.

Abstract: A map of the surroundings for a motorized domestic appliance is created by transmitting signals and allocating reflections to points. A local distribution of the points is formed. Points are discarded if a correspondence of the distribution to a straight line fails to reach a predefined degree. In a second variant, points whose distance from an average location exceeds a predefined value are discarded. The surroundings may be divided into tiles. A normal distribution transformation for the points of a tile specifies an average location and a variance of the points. The variance has two eigenvectors in two dimensions, each with an eigenvalue describing the variance contained in the eigenvector. A ratio between the larger and smaller eigenvalues describes an equal or unequal distribution of the variances. If, however, the quotient is, say, 10 or more, a large number of points of the tile can lie along a straight line.

Abstract: A moving method for a self-moving device, and a self-moving device are provided. The method includes: driving the self-moving device to move in a first advancing direction; determining whether the self-moving device can continue to move in the first advancing direction; and controlling the self-moving device to perform a first escape preprocessing operation, if the self-moving device cannot continue to move in the first advancing direction. When the self-moving device is encountered with a raised sill on the ground, the solution provided in the present disclosure enables the self-moving device to effectively cross the raised sill.
