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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Robot cleaner and method for sensing dust","description":"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 f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9770149","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
