Cleaning robot

A cleaning robot comprising:

• a housing comprising a cover, an oval-shaped base connected to the cover, and a pair of lateral plates movably connected to the cover and the base, respectively, and surrounding around a corresponding long outside of the cover and the base;
• a driver installed on an upper surface of the base and comprising a gear-box member movably mounted on a short side of the base, the gear-box member comprising a gear-box body fixed with the short side of the base and formed a tilt angle with ground or a lower wall of the base;
• a cleaning device movably connected to a bottom surface of the base and tightly fixed with the gear-box body, the cleaning device comprising at least one connecting member movably connected to the base, and at least one cleaning member tightly fixed with the connecting member, the cleaning member defining an inclined contacting surface relative to the ground to form the tilt angle with the ground same as that of the gear-box body and the ground, and comprising a water storage room installed with the connecting member and a cleaning portion mounted on the water storage room;
• and
• when the cleaning member obliquely rotating, a lowest point formed by the cleaning member and the ground created a high strength friction for driving the connecting member to rotate so as to the cleaning member follow rotating with the connecting member;
• and wherein
• water in the water storage room can be immersed into a bottom of the cleaning portion to make the cleaning portion clean water marks or grease marks on the ground during the cleaning member rotation, and the pair of lateral plates can move relative to the base and transmit a signal to the driver which can drive the cleaning device to move for changing a movement direction of the cleaning robot when the pair of lateral plates is touched.
