Abstract
A self-propelled, dust-collecting robot includes a chassis, an electric motor supported by the chassis, and first and second rechargeable battery packs disposed inside the chassis for supplying current to the electric motor. First and second castors are respectively disposed immediately underneath the first and second battery packs. Each of the battery packs has a pair of rails that respectively slide into and engage with complementary guide rails coupled to the chassis. A dust-collection box is removably disposed within the chassis. A dust-collection motor rotates a suction fan that is in fluid communication with the dust-collection box. At least one rotatable brush sweeps dust towards a suction port in fluid communication with the dust-collection box.
