ROBOT CLEANER AND METHOD FOR SENSING DUST
First Claim
1. A robot cleaner, comprising:
- a suction motor installed within a main body and configured to generate a suction force;
at least two conductive plates spaced apart from each other to form a flow path for external air introduced by the suction force; and
a calculator that measures a capacitance value between the at least two conductive plates.

Abstract
A robot cleaner is provided that may include a suction motor installed within a main body to generate a suction force, at least two conductive plates spaced apart from each other to form a flow path for external air introduced by the suction force, and a calculator to measure a capacitance value between the at least two conductive plates. Further, provided is a robot cleaner that may include a suction motor installed within a main body to generate a suction force, a porous structure having at least one through hole, through which external air introduced by the suction force may flow, at least one filter disposed on a surface of the porous structure to filter dust contained in the air, and a power supply configured to apply alternating current (AC) power to at least a portion of the surface of the porous structure.
