An autonomous lawn mower () comprises a mower body () having at least one motor () arranged to drive a cutting blade () and to propel the mower body () on an operating surface via a wheel arrangement. The mower body () includes a navigation system () arranged to assist a controller () to control the operation of the mower body () within the predefined operating area (). The navigation system includes an odometry module (), a rotatable optical surveying module (), a sonic obstacle detection module (), a heat absorbing unit set on the outer surface of the mower body () for directing the heat generated within the mower body towards the atmosphere, and a detachable docking module () arranged to receive the mower body ().

Autonomous lawn mower and a system for navigating thereof

A system and method for an autonomous lawn mower comprising a mower body having at least one motor arranged to drive a cutting blade and to propel the mower body on an operating surface via a wheel arrangement, wherein the mower body includes a navigation system arranged to assist a controller to control the operation of the mower body within a predefined operating area.

An autonomous lawn mower () and a system for navigating the same are disclosed. The autonomous lawn mower () comprises a mower body () having at least one motor () arranged to drive a cutting blade () and to propel the mower body () on an operating surface via a wheel arrangement. The mower body () includes a navigation system () arranged to assist a controller () to control the operation of the mower body () within the predefined operating area (). The system comprises a plurality of navigation modules (), each arranged to obtain individual navigation information associated with the navigation of the autonomous mower (). The navigation modules () operate to generate a virtual representation of the operation area () of the lawn mower () during an initialization mode, and the virtual representation of the operation area () is processed with the obtained navigation information during the operation of the lawn mower ().

A hybrid engine and battery generator and a method of operating the same. The generator is controlled to operate in at least three modes: a battery-only mode, a battery charging mode, and a boost mode. In the battery-only mode, the engine is off and an internal battery of the generator is used by an inverter to generate AC output. In the battery charging mode, the engine generates DC power, via an alternator and rectifier, which is used to charge the battery and to supply power to the inverter to generate AC output. In the boost mode, the battery and the engine generate DC power that is used by the inverter to generate an AC output with increased wattage, relative to the battery-only mode and battery charging mode. The generator automatically switches between the modes based on battery level and load demand.

A pressure washer is provided. The pressure washer includes a fluid inlet and a pump disposed to receive fluid from the fluid inlet. A spray gun is provided that includes a first outlet and a separate second outlet. A first conduit fluidly connects the fluid inlet and the pump with the first outlet and a second conduit fluidly connects the fluid inlet with the second outlet.

Dual flow pressure washer

A portable pressure washer system includes a frame having at least one strap configured such that the frame is supported by a user by way of the at least one strap. A torque generating device is supported by the frame and has an output shaft. A pump is selectively coupled to the output shaft to receive a torque generated by the torque generating device. The pump includes an inlet for connecting to a remote fluid source and an outlet for connecting to a high pressure fluid delivery mechanism. The pump receives a fluid from the remote fluid source by way of the inlet, is driven by the torque generating device to raise a pressure of the fluid to a high pressure fluid, and delivers the high pressure fluid to the high pressure fluid delivery mechanism by way of the outlet.

Portable pressure washer system

A floor cleaning attachment is configured to attach to a pressure washer lance to receive a flow of fluid. The floor cleaning attachment includes a housing that defines a suction space and includes an attachment point configured to attach to the pressure washer lance to receive the flow of fluid. A rotatable brush is coupled to the housing, a vacuum producing member is coupled to the housing, and a valve is coupled to the housing and movable between a first position in which the flow of fluid is directed onto a floor, a second position in which the flow of fluid is directed to the vacuum producing member to produce a partial vacuum, and a third position in which the flow of fluid is directed to the rotatable brush to rotate the brush.

A surface cleaner system includes a base assembly having a housing movable along a surface, a pump supported by the housing and operable to pressurize a fluid, and a prime mover supported by the housing. The prime mover is coupled to the pump to drive the pump. The surface cleaner system also includes a spray assembly coupled to the housing. The spray assembly is operable to discharge fluid from the pump toward the surface. The surface cleaner system further includes a spray gun in fluid communication with the pump to receive pressurized fluid from the pump. The spray gun includes an outlet portion that is connectable to the base assembly to direct the pressurized fluid from the pump into the spray assembly. When the outlet portion is disconnected from the base assembly, the spray gun discharges the pressurized fluid from the pump toward the surface without directing the pressurized fluid into the spray assembly.

Surface cleaner system

A nozzle is provided. The nozzle includes a cylindrical housing defining a fluid flow path therethrough about a longitudinal axis and a first finger mounted to a first end portion of the housing comprising a wedge disposed on an outer surface of the first finger. A hollow shroud is coaxially disposed around the housing and longitudinally movable with respect to the housing. An outlet aperture is disposed in fluid communication with the fluid flow path, and a ramp disposed within an internal surface of the shroud and engageable with the wedge.

Adjustable nozzle for pressure washer

A nozzle for use with a pressure washer, and the nozzle includes a body portion that defines a longitudinal axis and a head portion coupled to the body portion and in fluid communication with the body portion. The head portion includes a face substantially perpendicular to a longitudinal axis of the body portion. An elongated first slot is disposed upon the face of the head portion, and an elongated second slot is disposed upon the face of the head portion and in a nonparallel orientation with respect to the first slot. A fluid outlet aperture extends through the face and is at least partially located within at least one of the first and second slots to allow a fluid flow from within the body portion to exit the nozzle from the head portion.

Nozzle for use with a pressure washer

A power washer is provided with a transport frame, a wash unit and a gun. The wash unit and the gun may be separated from the transport frame to be used in multiple modes. Possible modes include a walk-behind mode, a spray mode and hand wash modes. A quick connection is also provided to make it easier to disconnect and reconnect various components of the power washer.

Multi-function power washer

A portable pressure washer includes a housing having a front end and a rear end defining a longitudinal axis. A handle has a first end extending from a rear portion of the housing and a second end terminating in a barrel. A first nozzle and a second aperture extend from the barrel. A fluid pump and a motor disposed are disposed within the housing, which includes a fluid inlet in fluid communication with the first nozzle and the second aperture.
