The embodiments include a primary frame (10) supported by two wheels (50), and connected to a towing vehicle via a tow bar (18). A cylindrical brush assembly (1) is mounted on a secondary frame (12), which rotates around the primary frame. The brush rotation is driven by an electric motor (110, 220) attached to the secondary frame. The brush rotation goes counter to the wheels' rotation. The amount of pressure between the brush and the ground is controlled by the length of a spring (23) that links the two frames. In one embodiment, the brush axis forms an angle (280) with the wheels' rotation axis, and the debris gets pushed to the side as the sweeper moves forward. In another embodiment, the brush axis is parallel to the wheels' rotation axis and the debris is driven around the brush by a wrap-around guide (100), into a hopper (140).
