  • Publication number: 20250176780
    Abstract: An apparatus is described for determining a usage order for a cleaning robot. The apparatus is configured so as to determine a quantity of cleaning orders already executed that were executed by the cleaning robot within a previous operating period. The individual cleaning orders each indicate a scope of the cleaning task that is performed by the cleaning robot in the respective cleaning order. The apparatus is furthermore configured so as to determine and/or adapt at least one usage order for a preceding point in time on the basis of the quantity of cleaning orders already executed, wherein the usage order indicates a scope of the cleaning task to be performed by the cleaning robot in the usage order.

    Abstract: A method for controlling a mobile, self-propelled appliance, in particular a floor cleaning appliance such as a robot vacuum cleaner and/or a sweeper and mopping robot so as to mop up an accumulation of liquid, includes driving on a floor surface intended for cleaning in a direction of travel in a forward movement of the appliance and cleaning the floor surface by using a dry cleaning module and/or a wet cleaning module of the appliance. The accumulation of liquid is detected in the direction of travel in front of the appliance in a moist area. The forward movement in front of the moist area is terminated and the appliance is rotated about substantially 180°. Driving on the moist area in a reversing movement in the direction of travel of the appliance and mopping up the accumulation of liquid using the wet cleaning module is carried out.

  • Publication number: 20240285142
    Abstract: A method for collision-free wall-cleaning and/or edge-cleaning by a mobile, self-driving appliance, in particular a floor cleaning appliance for autonomous processing of floor surfaces, such as a robotic vacuum cleaner and/or a sweeping and/or mopping robot, which includes a laterally disposed wall tracking sensor and a distance sensor, includes travelling along a wall section at a first distance determined by measured values of the wall tracking sensor, and simultaneously measuring a second distance to the wall using the distance sensor. A difference is determined between the distance values of the wall tracking sensor and the distance sensor by a computer facility of the appliance. A collision-free distance value with respect to the wall section is determined as a function of the difference by the computer facility. Subsequent cleaning journeys are controlled by a closed-loop distance control as a function of the collision-free distance value that is determined.

  • Publication number: 20240285141
    Abstract: A method for improved cleaning of a spatially delimited region by using a robot vacuum cleaner having a fan, includes increasing a fan rotation speed of the robot vacuum cleaner, and therefore increasing a vacuuming power, shortly before reaching the region. The fan rotation speed is reduced again after leaving the region, so that increased power and increased noise emission only occur in the delimited region. A robot vacuum cleaner with a sensor facility, a fan and a computer facility for carrying out the method, is also provided.

  • Publication number: 20240225388
    Abstract: A floor vacuum cleaner for cleaning a floor surface has a chassis with a chassis frame for traveling over the floor surface. A suction nozzle aspirates an airflow in the region of the floor surface. The suction nozzle is mounted relative to the chassis in the direction of travel to the front left and front right in each case by way of a mounting arrangement formed of a journal and a guide. The mounting arrangement allows a tilting of the suction nozzle about the journals, a rotation of the suction nozzle about a longitudinal axis, and a vertical movement of the suction nozzle, but a movement of the suction nozzle in the longitudinal direction of the chassis is prevented.

  • Publication number: 20240065510
    Abstract: An operating method operates a mobile, self-moving appliance. The method is performed in a wall following mode and includes: moving the mobile, self-moving appliance along a first wall; detecting a second wall, which forms a corner with the first wall; and moving away from the second wall, until there is a first predetermined distance between a front point of a housing corner of the appliance and the second wall. The appliance is rotated about a center point so that the front point of the housing corner faces the second wall and is at a second predetermined distance therefrom. Forward movement of the mobile, self-moving appliance proceeds so that the appliance is aligned parallel to the second wall. The second predetermined distance between the front point of the housing corner and second wall remains substantially constant during the forward movement. A mobile, self-moving appliance is configured to perform the method.
