An automated cleaning device includes a chassis, a controller operably connected to a drive assembly and configured to move the chassis within an area to be cleaned in repeated cleaning cycles, a cleaning unit carried by the chassis, a sensor configured to detect material drawn into the cleaning unit and provide a debris signal corresponding to an amount of material drawn into the cleaning unit, the controller being operably connected to the sensor and configured to generate a high-material indicator in response to the debris signal exceeding a predetermined debris threshold, and determining whether the autonomous cleaner is in a high traffic area when the chassis moves within the area to be cleaned based on locations of high-material indicators.

Autonomous vacuum operation in response to dirt detection

A handheld vacuum cleaner includes a housing, a motor, and a dirt cup. The housing defines a top, a bottom, a motor chamber, a dirty air inlet at a front of the housing, a handle at the rear of the housing, a clean air outlet, and an airflow path from the dirty air inlet to the clean air outlet. The handle has a grip portion. The housing further includes a continuous elongate structural member extending from the dirty air inlet into the grip portion of the handle. The motor is disposed in the motor chamber. The dirt cup is coupled to the elongate structural member. The dirt cup is in fluid communication with the dirty air inlet and the motor. The elongate structural member defines a portion of the airflow path extending from the dirty air inlet.

Vacuum cleaner assembly

A handheld vacuum cleaner includes a housing, motor, filter access door, filter, and dirt cup movably coupled to the housing. The housing defines a top, bottom, motor chamber, dirty air inlet, handle, clean air outlet, and air flow path. The air flow path is routed from the dirty air inlet to the clean air outlet. The motor is disposed in the motor chamber and defines a motor axis. The filter access defines a filter chamber with the housing. The filter is disposed in the filter chamber and defines a filter axis. The dirt cup defines a dirt cup axis extending parallel to the motor axis and filter axis. The filter access door is located below the filter axis. When the filter axis door is removed, the filter is removable in a downward direction from the filter chamber.

Handheld vacuum cleaner

A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, the housing further including a handle along a handle axis. A suction nozzle is along a suction nozzle axis that extends in a direction from the front end toward the back end. The handheld vacuum further includes a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust. A battery that supplies power to the suction source and the battery is coupled to the housing adjacent an end of the handle. The handle extends between the battery and the cyclonic separator.

A vacuum cleaner including a base, a spine, a dust collection assembly, and a battery. The spine is connected to the base. The spine includes a handle portion and a mounting portion. The battery is connected to the mounting portion of the spine. The battery is pivotable between a first position in which the battery is fixedly connected to the spine, and a second position in which the battery is pivoted away from the spine. The dust collection assembly is connected to the spine.

Battery powered vacuum cleaner

A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, the housing further including a handle along a handle axis the handle axis extends in a direction from the back end toward the front end. A suction nozzle is along a suction nozzle axis that extends in a direction from the front end toward the back end. The handheld vacuum further includes a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust. The cyclonic separator includes a longitudinal axis that extends in a direction from the first side toward the second side and the handle axis and the suction nozzle axis intersect at an obtuse angle.

A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, a handle having a longitudinal axis that extends in a direction toward the front and back ends of the housing, a suction source, and a cyclonic separator. The cyclonic separator includes a cylindrical wall having a first end and a second end, a first end wall located at the first end of the cylindrical wall, a dirty air inlet, a clean air outlet, a debris outlet adjacent the second end of the cylindrical wall, and a longitudinal axis surrounded by the cylindrical wall and the longitudinal axis of the cyclonic separator extends in a direction toward the first and second sides of the housing. The housing includes an aperture that extends through the first side, and the first end wall of the cyclonic separator is removable through the aperture.

A cleaning device may include a solution tank configured to store cleaning solution. The device delivers the cleaning solution from a pump discharge of the cleaning device to a flow meter. The device initiates a priming mode by opening a first valve associated with a bypass line of the device, closing a second valve associated with a cleaning head of the cleaning device, and delivering the cleaning solution from a discharge of the flow meter to the inlet of the solution tank through the bypass line. When the device is primed, it initiates cleaning by closing the first valve associated with the bypass line, opening the second valve associated with the cleaning head, and delivering the cleaning solution to the cleaning head.

Cleaning device with single tank recycling system

A method of cleaning an area using an automatic cleaning device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by an automatic cleaning device, a position of the automatic cleaning device on the surface relative to the edge and using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path. The path may be substantially parallel to the edge, and the edge may be located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device.

Methods and systems for movement of an automatic cleaning device using video signal

A cleaning device may include a solution tank configured to store cleaning solution. The solution tank may include an inlet and an outlet. The cleaning device may include at least one discharge line filter in fluid communication with the solution tank and a pump having a pump intake and a pump discharge. The pump may be configured to direct cleaning solution from the solution tank outlet through the at least one discharge line filter. The cleaning device may include a cleaning head in fluid communication with the pump discharge and a bypass line in fluid communication with the pump discharge and the inlet. The bypass line may be configured to divert cleaning solution received from the pump discharge away from the cleaning head and toward the solution tank.

An agitator arrangement for a floor cleaning machine is disclosed including various multi-agitator configurations or one agitator configuration with a plurality of brushes with bristle bundles for rotation of the brushes about an approximate vertical axis with a plurality of stationary downwardly projecting, bristle bundles arranged in at least one row approximately side by side with or without an offset. In particular, agitator assemblies having multiple brushes that rotate in approximately a horizontal and approximately a vertical axis or that rotate at different speeds and torque. Other configurations may include multi-row multiple vertical axis agitators.
