Claim 10:
11. A method of collecting dirt from a surface to be cleaned by means of an automatic and currentless dirt remover, comprising steps of:
placing the dirt remover on the surface to be cleaned, the dirt remover including a dirt-collecting body having a surface which is chemically adhesive and collects the dirt and a rolling-action sheath body which defines a receiving space in which the dirt-collecting body is received, the sheath body having openings in order to provide external access to the dirt-collecting body, wherein the dirt-collecting body contacts an inner surface of the sheath body, wherein the dirt-collecting body is not secured to the sheath body, and wherein the dirt remover is configured to roll via its sheath body along the surface to be cleaned in order to collect dirt present at the surface to be cleaned since the dirt collected adheres to the adhesive surface of the dirt-collecting body,
initiating a movement of the dirt remover such that the dirt remover is propelled currentlessly, and
effecting an automatic and currentless cleaning of the surface to be cleaned since the dirt remover rolls via the sheath body along the surface to be cleaned such that the surface of the dirt-collecting body comes into contact with the surface to be cleaned through the openings of the sheath body in order to collect the dirt present there that adheres to the surface of the dirt-collecting body,
wherein the movement of the dirt remover is initiated by a movement of a user, wherein the automatic and currentless cleaning is effected through the movement of the user.
