Robot cleaner
First Claim
Patent Images
1. A robot cleaner comprising:
- a body to travel on a floor;
an obstacle sensing unit to sense an obstacle that the body is approaching;
an auxiliary cleaning unit mounted to a bottom of the body to be extendable and retractable from the body; and
a control unit to control extension or retraction of the auxiliary cleaning unit when the obstacle is sensed,wherein the control unit prevents the auxiliary cleaning unit from extending in response to at least one signal being received from a charger.

Abstract
A robot cleaner includes a body to travel on a floor; an obstacle sensing unit to sense an obstacle approaching the body; an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable; and a control unit to control extension or retraction of the auxiliary cleaning unit when the obstacle is sensed. The control unit prevents the auxiliary cleaning unit from extending if a signal is received from a charger.
