A self-driven automatic cleaner, designed to be movable in every direction on a floor under its own power while performing a wet-wiping operation and/or a vacuum-cleaning operation, is disclosed. In the primary embodiment, the cleaner is designed to move on the floor forward or backward by two forward-backward moving units (9, 9') while performing both the wet-wiping operation and the vacuum-cleaning operation. In this cleaner, each of the two forward-backward moving units (9, 9') is provided with a roller (10) having a damp cloth (9), thus performing the wet-wiping operation while moving the cleaner forward or backward. A lateral moving unit (25) is included in the cleaner, thus selectively moving the cleaner laterally on the floor when the cleaner collides against a hindrance and is stopped. The cleaner only performs a vacuum-cleaning operation during such a lateral movement. In the second embodiment, the cleaner (1) is free from the parts for performing a vacuum-cleaning operation, but is designed to automatically perform only the wet-wiping operation. In the third embodiment, the two forward-backward moving units are free from the damp cloth (9), and so the cleaner of the third embodiment only performs the vacuum-cleaning operation. The cleaner of this invention is also designed to be selectively operated in a self-driven mode or in a manual operational mode. |
