Abstract: Disclosed is a cleaner, including a main body having an operating part configured to receive a command and a main battery configured to supply power; and a cleaning module connected to the main body and configured to generate steam to clean a cleaning region, and the cleaning module may include: a cleaning module housing connected to the main body, forming an external appearance, and forming a space on an inside thereof; a heater disposed on an inside of the cleaning module housing and configured to generate steam from water; a water container disposed above the heater and configured to supply the water to the heater; and a heater disposition part recessed upward from a lower surface of the water container and allowing at least a part of the heater to be inserted thereinto. The present disclosure relates to a cleaner capable of preventing burns to a user even if the user comes into contact with the cleaning module since heat dissipated from the heater is shielded by the water container, and lowering a height of the cleaning module thanks to a special structure of the water container.

Abstract: Disclosed is a mobile robot including a body, a rotating plate rotatably installed on the body and having a lower surface where a mop portion is attached, and an attachment guider installed on the lower surface of the rotating plate to guide an attachment position of the mop portion. The attachment guider includes a guide rim and a plurality of elastic pieces. The guide rim is disposed to surround a rotation axis of the rotating plate. The plurality of elastic pieces extend from the guide rim in a direction toward the rotation axis, have a free end protruding to a lower side or downward than the guide rim, and are spaced apart from each other along a circumference of the guide rim.
