Title: SELF-PROPELLED CLEANING DEVICE, CONTROL METHOD FOR SELF-PROPELLED CLEANING DEVICE, AND PROGRAM
Abstract:
A self-propelled cleaning device (1) comprises: a remaining battery power detection unit (17) that detects the remaining battery power of a rechargeable battery (16); a reception strength measurement unit (12) that measures the reception strength of a wireless signal received from a charging device (2); a prescribed value setting unit (13) that sets a prescribed reception strength level; and a traveling area determination unit (14) that, in accordance with the remaining battery power, the reception strength, and the prescribed reception strength level, determines at least one of a cleaning area and a traveling area for the self-propelled cleaning device. If the remaining battery power is greater than or equal to a first prescribed value, the traveling area determination unit determines at least one of the cleaning area and the traveling area while prioritizing an area in which the reception strength is lower than the prescribed reception strength level over an area in which the reception strength is high. Thus, while the remaining battery power is greater than or equal to the prescribed value, the self-propelled cleaning device can be made to travel while prioritizing an area that is distant from the charging device.
