An assembly for releasable attachment to a vehicle. The assembly comprises a frame including a mounting member configured to be mounted onto the vehicle, a plow blade mounted to the frame and a power broom coupled to the frame and disposed between the mounting member and the plow blade. The power broom is configured to be disposed in front of a most forward wheel of the vehicle relative to a forward direction of travel of the vehicle. The power broom is also configured to rotate to sweep snow away from the power broom.

A large to medium-size sweeping and mopping vehicle and a mopping vehicle are provided. The large to medium-size sweeping and mopping vehicle includes a vehicle body, and a disc-type sweeping mechanism, a round-roller-type sweeping mechanism and a first mopping mechanism sequentially disposed along the vehicle body; the disc-type sweeping mechanism including a clean water tank and disc-type sweeping edge brushes driven by a motor and disposed obliquely with respect to ground, the clean water tank being disposed in front of the vehicle body driver zone, and a nozzle being disposed above each disc-type sweeping edge brush and in communication with the clean water tank; the round-roller-type sweeping mechanism including a refuse collector and a round-roller-type main sweeping brush driven by the motor to rotate horizontally; and the first mopping mechanism including a dragging roller, a guiding mopping roller, a guiding roller, a ring-shaped mop and a washing water tank.

In accordance with one aspect, a lawn sweeper for being towed by a lawn tractor including a body, a rotatable brush mounted to the body, and a motor for rotating the brush independently of the rotation of at least one wheel of the lawn sweeper. The lawn sweeper further includes a remote control for being operated by a user of the lawn tractor to control the motor. In another aspect, a lawn sweeper having a pair of wheels rotatable about a wheel axis, a body shiftable between raised and lowered positions relative to the wheels, and brush mounted to the body and rotatable about a brush axis. The brush axis is substantially vertically aligned with the wheel axis when the body is in the raised position and the lowered position.

A vehicle assisted working device for cleaning streets and similar surfaces includes at least one brush for detachment of the extraneous material from the surface, element for providing an underpressure for a suction of the detached material into the air flow from the surface, units for separating the detached material from the air flow and for providing an overpressure and return of the separated air to the surface. At least one brush is arranged to rotate counter-wise to the intended direction of movement of the working device, so that the element are ordered in such a way that when the working device is intended to move over a spot to be cleaned, it treats the spot in the following order: suction of the extraneous materials, at least one brush and mechanism for return of the separated air to the surface. Also disclosed are a system and method for cleaning.

A power split and creep drive system for street sweeper or like specialty vehicle having a single engine is disclosed. The system intends to retrofit and convert on-highway truck chassis into specialty vehicles capable of performing work function and moving at creeping speed, such as a street sweeper. It includes a hydraulic work circuit or power-take-off (PTO) port, a planetary gear set, a hydraulic system comprising pumps and motors to drive the working devices and balance the demand between propulsion and work function such as sweeping. The planetary gear set includes an input shaft connecting to a transmission output shaft of the chassis, a first output shaft connecting to a hydraulic machine, and a second output shaft to vehicle propulsion drive shaft.

A sweeping machine for mounting to a blower is adapted for sweeping debris, e.g., snow, from an area around an obstacle, e.g., fire hydrant. The sweeping machine comprises a rotating brush having an axis of rotation which is horizontal, a frame for the rotating brush, an arm extending from a proximal end to a distal end to which the frame is secured, a blower, and a pivoting mechanism secured to the blower. The pivoting mechanism is adapted to swivel the arm upwardly to lift the rotating brush and to swivel the arm within a horizontal plane to move the rotating brush horizontally relative to the blower. Thereby, the sweeping machine is adapted to sweep debris from the area around the obstacle by the rotating brush toward the blower which is itself adapted to blow the debris away from the obstacle.

A street sweeper configured to clean a street can include: at least one broom or sprayer configured to clean a street, a street surface deviation detection device coupled to the street sweeper, the street surface deviation detection device being configured to detect visual signatures of defects in a surface of the street; and a position device to measure the position of the street sweeper, wherein the position device is programmed to send the position to a central server.
