ROBOT CLEANER AND METHOD OF CONTROLLING THE SAME
First Claim
1. A robot cleaner comprising:
- a main body that navigates a floor;
a first detector that detects an obstacle;
an auxiliary cleaner that is mounted on the main body to protrude and retract;
a second detector that detects a protrusion state or a retraction state of the auxiliary cleaner; and
a controller that determines an abnormal operation of the auxiliary cleaner based on a result of the detection of the second detector and controls a protrusion operation or a retraction operation of the auxiliary cleaner according to a result of the determination.
