Cleaner and control method thereof
First Claim
1. A robot cleaner including a body, a drive device, and a main brush to sweep up loose debris from a surface to be cleaned, comprising:
- at least one trap member to trap static charge;
a ground member to create a potential difference in cooperation with the trap member; and
a discharge member electrically connected to the trap member and the ground member and serving to discharge the trapped static charge.

Abstract
A robot cleaner having a static-charge removal device to prevent deterioration in performance or damage to an interior circuit of the cleaner due to static charge. The robot cleaner includes a conductive trap member to trap frictional static charge, a discharge member electrically connected to the trap member to discharge the static charge, trapped by the trap member, into another kind of energy, for example, light, sound, or kinetic energy, and a ground member located on the robot cleaner while being connected to the discharge member. The robot cleaner prevents adherence of dust, loose debris, etc. as well as damage to an interior circuit thereof due to static charge, thereby efficiently performing a cleaning operation.

12. A control method of a robot cleaner comprising:
-
trapping frictional static charge using a conductive member; electrically connecting a ground member to the conductive member in which the static charge has been trapped, so as to create a potential difference between the ground member and the conductive member; and discharging the trapped static charge into another kind of energy.

13. A cleaner comprising:
-
a suction port through which loose debris is suctioned; an extension pipe connected to the suction port; a trap member to trap static charge, generated in the extension pipe as the suctioned loose debris rubs against the extension pipe, using a conductive member; and a control device including a discharge member electrically connected to the trap member and serving to discharge the static charge trapped by the trap member into another kind of energy, and a ground member located on the cleaner while being connected to the discharge member. - View Dependent Claims (14, 15)
