Benefits of technology

The invention is about a cleaning robot that detects movable obstacles in an environment and determines which areas have not been cleaned well or are difficult to clean. The robot can also detect if the obstacle has been removed and will automatically clean the area where it was previously located. This makes it easier for users to achieve optimal cleaning results. The robot can also output a message to the user if they have removed a movable obstacle, allowing them to easily return it to its original position.

Problems solved by technology

If both aforementioned prerequisites apply to the same environment section of the environment, it is concluded that the obstacle present at this location prevents optimal cleaning, particularly even cleaning, of the environment section.
The cleaning appliance furthermore determines environment sections that could not be cleaned at all or only cleaned with little success.

Embodiment Construction

[0026]FIG. 1 shows an example of a self-propelled cleaning appliance 1. In this case, the cleaning appliance 1 is a vacuuming robot with a cleaning element 16 in the form of a cleaning brush that rotates about an essentially horizontal axis. The cleaning appliance 1 has wheels 15 and a drive unit 2 for the wheels 15 in order to realize its autonomous movement, wherein said drive unit 2 comprises a not-shown electric motor. The cleaning appliance 1 furthermore has a communication interface 3 for the wireless communication with an external terminal 14 (see FIG. 3). The cleaning appliance 1 can be incorporated, for example, into a home network or also connected to the Internet by means of communication interface 3. An obstacle detection device 5 of the cleaning appliance 1 is designed for detecting obstacles 6, 7 in the environment of the cleaning appliance 1. The obstacles 6, 7 may on the one hand be stationary obstacles 6, e.g., large pieces of furniture such as cabinets, beds and th...

Abstract

A self-propelled cleaning appliance has a drive unit for moving the cleaning appliance within an environment, a communication interface for outputting a message to a user of the cleaning appliance, an obstacle detection device for detecting obstacles within the environment and a computing device that generates an environment map based on the obstacles detected by the obstacle detection device and for transmitting control commands to the communication interface. The computing device is designed for determining a first environment section, in which a position of a movable obstacle changes in a recurring manner, and for determining a second environment section that could only be cleaned incompletely. The computing device compares the position of the determined first environment section with the position of the determined second environment section and outputs a message concerning the movable obstacle to a user of the cleaning appliance via the communication interface if the positions match.
