Description

A ROBOT VACUUM CLEANER AND THE CONTROL METHOD THEREOF
The present invention relates to a robot vacuum cleaner which moves independently of the user and which cleans the floor or floor coverings, and to the control method thereof.
Vacuum cleaners are used for cleaning the floors of closed environments such as house, office, etc. The vacuum cleaners are used by a user, which causes loss in both labor and time. In order to eliminate this disadvantage, vacuum cleaners called robot vacuum cleaners which move without the need for user intervention are developed. The robot vacuum cleaners clean the floor of the environment by moving around according to a certain navigation algorithm. The performance of the robot vacuum cleaners are evaluated by taking into account three basic factors which are coverage area, cleaning rate and detection effect. In order to increase the performance, various sensors are provided on the robot vacuum cleaner and various algorithms used depending on the data received from the sensors are developed. Generally, the robot vacuum cleaners scan the house area by means of the sensors and automatically perform the cleaning process in a periodic manner. However, the robot vacuum cleaner continues to regularly clean the regions determined by the user even if the user is not at home. The user turns off the robot vacuum cleaner if he/she is not at home for a long time, and in this case the cleaning process cannot be performed.
In the state of the art United Kingdom Patent No. GB2394895, a robot vacuum cleaner comprising a camera is disclosed.
