Floor-cleaning device
First Claim
1. A floor-cleaning device, comprising:
- a main body;
a pair of driving units deposited at the left and right sides of the main body for propelling the main body to move on a substantial surface;
a moving-along-edge sensing unit deposited at the left or right side of the main body that is composed of non-contact sensing components whereby the main body can move along the edge of an external object with a predetermined distance and along a slightly S-shaped route;
a cleaning unit settled at the bottom of the main body; and
a control unit and a power-supply unit, which are settled inside the main body and electrically connected with the,above units in the manner that the driving units can propel the main body to move and the cleaning unit can conduct cleaning during the movement of the main body.

Abstract
A floor-cleaning device primarily comprises a pair of driving units provided at two opposite sides of a main body thereof wherein the driving units are electrically connected to a control unit and a power-supply unit which are both deposited in the main body so that the main body is capable of moving freely on a substantial surface. Particularly, a moving-along-edge sensing unit is provided at the left or right side of the main body to conduct a movement of the main body along the edge of the surrounding objects. The sensing unit is composed of non-contact sensing components so as to permit the main body to move along the edge of the surrounding objects with a predetermined distance in a continuous slightly oscillatory S-shaped route. In virtue of the sensing unit, the main body can automatically approach and connect to a charger for automatic charge.

18. A floor-cleaning device, comprising:
-
a main body; a pair of driving units positioned at the left and right sides of the main body for propelling the main body to move on a substantial surface; a moving-along-edge sensing unit deposited at the left or right side of the main body that is composed of non-contact sensing components whereby the main body can move along the edge of an external object with a predetermined distance and along a slightly S-shaped route; a cleaning unit settled at the bottom of the main body; a control unit and a power-supply unit, which are settled inside the main body and electrically connected with the above units in the manner that the driving units can propel the main body to move and the cleaning unit can conduct cleaning during the movement of the main body; a charger, which is deposited at a predetermined location at the edge of an external object and is connected with a power source, for emitting a location signal; a power-receiving unit, which is settled at the surface of the main body, for connecting with the charger to charge the power-supply unit inside the main body; a signal-receiving unit, which is provided on the main body and is electrically connected with the control unit, for receiving the location signal emitted by the charger; and a power-level detecting unit, which is provided on the main body and is electrically connected with the control unit as well as the power-supply unit, for detecting the power level of the power-supply unit wherein when the remaining power level decreases to a predetermined low-power default, the power-level detecting unit emits a low-power signal to the control unit so that the control unit starts the moving-along-edge sensing unit accordingly to propel the main body moving along the edge of the external object until the signal-receiving unit detects the location signal of the charger, and the control unit controls the left and right driving units to make the main body rotate so that the power-receiving unit and the charger can be coupled for charging the cleaning device. - View Dependent Claims (19, 20)
