A pick-up broom attachment for use with a work vehicle that includes a hood assembly, a bucket portion, and a water spray bar. The hood assembly includes a housing, a rotatable brush of generally cylindrical profile mounted for rotation, and a drive motor coupled to the housing for rotating the rotatable brush. The bucket portion is in coupled engagement behind and with the hood assembly and includes: a collection bin defined by a bottom bucket panel, a pair of side bucket panel members, and a rear bucket wall; an internal water tank located in a cavity in the bucket portion located rearward of the rear bucket wall; and a back panel located rearward of the internal water tank that includes implement interface members for connecting with a work vehicle. The water spray bar is mounted to the housing of the hood for delivering water in front of the hood assembly.

Pavement sweeping apparatuses may include a directionally mobile apparatus frame. At least one pickup unit may be carried by the apparatus frame. At least one actuatable first side edge broom may be carried by the apparatus frame generally on the first side and forward of the at least one pickup unit. At least one actuatable first side curb broom may be carried by the apparatus frame generally on the first side and forward of the at least one pickup unit. At least one actuatable second side edge broom may be carried by the apparatus frame generally on a second side and forward of the at least one pickup unit. At least one actuatable second side curb broom may be carried by the apparatus frame generally on the second side and forward of the at least one pickup unit. Pavement sweeping methods are also disclosed.

A modular robot is provided. The modular robot includes a sweeper module having a container for collecting debris from a surface of a location. The sweeper module is coupled to one or more brushes for contacting the surface and moving said debris into said container. Included is a robot module having wheels and configured to couple to the sweeper module. The robot module is enabled for autonomous movement and corresponding movement of the sweeper module over the surface. A controller is integrated with the robot module and interfacing with the sweeper module. The controller is configured to execute instructions for assigning of at least two zones at the location and assigning a work function to be performed using the sweeper module at each of the at least two zones. The controller is further configured for programming the robot module to activate the sweeper module in each of the two zones. The assigned work function is set for performance at each of the at least two zones. The work function can be to sweep, to scrub, to polish, to mow or to perform different work functions over zones of a location, and providing remote access to view real-time operation of the modular robot, and to program zones and other control parameters of the modular robot.

A curb brush device for sweeping a newly formed curb includes a frame for attachment to a vehicle such that the frame extends forwardly from the vehicle. The frame includes a frame attachment bracket and a rail coupled to the frame attachment bracket. A brush arm is coupled to the rail and is extendable laterally from the rail. A brush is coupled to the brush arm. The brush is rotatable for sweeping a surface laterally offset from the vehicle.

A switching system, in particular of an on-board electrical system of a motor vehicle having a first disc which has a first, a second, a third, and a fourth stationary contact. The second and the third stationary contact, are electrically contacted by a first contact bar of the first disc. The switching system also has a second disc which has a first, a second, a third, and a fourth movable contact. The first and the second movable contact are electrically contacted by a second contact bar of the second disc, and the third and the fourth movable contact are electrically contacted by a third contact bar of the second disc. The second disc is rotationally mounted about a rotational axis relative to the first disc, wherein all the contacts are electrically connected in series in an angular position. A circuit breaker is also provided that includes a switching system.

A method for the operation of a cleaning vehicle, in particular a street sweeper capable of being operated in automated fashion, by a control device. A trajectory is calculated and control commands are produced for a longitudinal guiding and transverse guiding of the cleaning vehicle during travel of the calculated trajectory. Measurement data are received from at least one sensor in order to ascertain a cleaning region. At least one actuator is controlled, based on the received measurement data, in order to position a cleaning device of the cleaning vehicle in the longitudinal direction and/or transverse direction relative to a direction of travel of the cleaning vehicle, in order to clean the cleaning region. A control device, a computer program, and a machine-readable storage medium are also described.

A road or parking lot sweeper head comprises a sweeper base chassis comprised of a wheel carriage having at least two wheels attached. The wheel carriage attaches to an outer side of the sweeper base chassis and comprises a first wheel on a first side of the sweeper base chassis and a second wheel on a second side of the sweeper base chassis. Wherein the first wheel and the second wheel position the sweeper head above a surface at a proper operating height for an associated vacuum and to engage the surface in operation and prevent any portion of the sweeper head from contacting and damaging said surface.
