An apparatus and method for clearing paver joints including high pressure water jets along a transverse direction to impact paver joints below the jets. The jets are moved in a longitudinal direction to clear joints in a transverse swath. The high pressure water jets are provided by plural nozzles arranged spaced-apart across the transverse direction and high pressure water is delivered through the nozzles to impact paver joints below the nozzles

A mobile pressure washer can include a wheeled chassis, a power plant supported by the wheeled chassis, a fluid pump a fluid pump coupled to and driven by the power plant, a sprayer in fluid communication with the pump, a chemical solution container, and a container holder for supporting the chemical solution container. In some examples, the container holder has a frame operably connected to the wheeled chassis and has a container support mounted to the frame, the container support including a base wall and a sidewall defining a receptacle for receiving and supporting a container in fluid communication with the pump.

Surface cleaning device for cleaning an floor surface comprising an inner space forming casing and a liquid dispenser positioned in the inner space. The liquid dispenser 3 comprises a motor driven rotor shaft which defines an axis of rotation. Rotor arms extend radially away from a rotor shaft. Each rotor arm comprises a blade to thrust a volume of liquid medium away from the inner space in a driving direction towards a casing outlet. The liquid dispenser comprises at least one nozzle for jetting a stream of liquid onto the floor surface. The at least one nozzle has a central axis which is inclined positioned in a forward direction with respect to the driving direction under an angle of inclination with respect to the axis of rotation.

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.

An arm assembly for a waterjet truck according to an exemplary aspect of the present disclosure includes a traversing mount bracket at a first end of the arm. The traversing mount bracket is configured to permit the arm to translate in a linear direction. The arm further includes a joint configured to permit rotational movement.

A mobile surface maintenance machine embodiment includes a mobile body, a solution tank for containing a cleaning fluid, wheels for supporting the mobile body, a maintenance tool(s), an output channel, an electric power source, a first electric motor, and a pressure washer. The pressure washer includes a spray wand, a pressure pump, and a second electric motor. The pressure pump is fluidly coupled to the spray wand and to the solution tank. The pressure pump is configured to pressurize the cleaning fluid supplied to the spray wand. The second electric motor is operatively coupled to and configured to drive the pressure pump. The second electric motor is configured to receive electric power from the electric power source and is commonly powered by the electric power source that provides power to the first electric motor. The second electric motor is separate from the first electric motor.

A backpack blower is provided with a water spray capability to suppress the generation of dust when used as a blower, and to also allow for use as a basic power washer. A leaf blower power unit having an engine driving a fan is interconnected with a wand having an outlet orifice. A spray nozzle is positioned within the wand adjacent the outlet orifice. A source of liquid to be sprayed is interconnected through a control valve to the spray valve such that a spray of water can be introduced into the vortex of the air being emitted from the wand. Both the speed of the airflow and volume of the water being introduced into the vortex may be regulated by the user in accordance with the use to which the unit is put.

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.
