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.

An outdoor surface cleaning apparatus having a handle, a power head with a prime mover, an attachment head having a cleaning attachment, and a spray mechanism. The spray mechanism includes a first fluid input, a second fluid input, a cleaning fluid output, and a mixing assembly. The mixing assembly is in fluid communication with the first fluid input, the second fluid input, and the cleaning solution output.

A roadway sweeper vehicle includes one or more processors and a control console allowing the vehicle operator to select one of a plurality of available engine speeds. A power increase assist feature is available through a throttle (e.g., pedal) that provides an increased power output of the vehicle engine for a momentary or transient period of time. The additive engine speed may be calculated based on a detected position of the throttle or determined from a lookup table based on the user-selected engine speed. Related methods are also described.

An automated road sweeper is provided including transport apparatus suitable to allow the sweeper to travel on a road surface including debris, a plurality of cleaning members arranged at fixed points located in different portions of the sweeper and suitable for cleaning within predetermined cleaning areas, and a selector operatively connected to the cleaning members, suitable for scanning the road surface and locating the debris so as to select and exclusively operate the cleaning members, the cleaning area of which covers the debris during the movement of the sweeper.

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.

The invention provides a rugged cleaning device configured to clean outdoor surfaces using a variety of fluids and techniques. The outdoor cleaning device includes a brush head, a motor and a transmission for providing a driving force to the brush head, a fluid tank for storing a fluid (e.g., a cleaning solution or detergent), and a controller for controlling mixing (or not mixing) the fluid stored in the fluid tank during operation of the outdoor cleaning device. The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via a plurality of nozzles. The nozzles may be formed via grooves on an inner cover and an outer cover may be provided to close off the grooves to form fluid channels. The fluid channels enable the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.

The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via at least one nozzle. The at least one nozzle may be secured to a guard cover via grooves on an inner guard cover and an outer guard cover. The nozzle(s) enables the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.

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.

A nozzle apparatus includes a manifold defining a nozzle cavity within an interior, a fluid inlet passage, a fluid outlet passage, an air outlet passage, and an air inlet passage. A nozzle holder and a nozzle element are selectively pivotable within the nozzle cavity. In the nominal position, the nozzle element inlet is oriented toward the fluid passage inlet and the nozzle element outlet is oriented toward the fluid passage outlet such that the primary fluid flows through the fluid inlet passage and out of the nozzle outlet through the fluid outlet passage. In the cleaning position, the nozzle element inlet is oriented toward the air outlet passage and the nozzle element outlet is oriented toward the air inlet passage such that the flow of air is directed through the air inlet passage, and out of the air outlet passage to direct debris out through the air outlet passage.
