    Abstract: A handle assembly for a vacuum cleaner that includes a handle, a duct, a valve assembly, and a cover. The handle is attached to the duct, which has an inlet end, an outlet end, and a bleed aperture between. The valve assembly includes a valve and an actuator. The valve is moveable between closed and open positions by the actuator to close and open the bleed aperture. The cover surrounds the duct such that an upper part overlies the bleed aperture and valve. Holes are formed in a lower part of the cover. Suction at the outlet causes a primary airflow to be drawn into the duct via the inlet. When the valve is in the open position, the suction causes a secondary airflow to be drawn in through the holes, around the space between the duct and the cover, and into the duct via the bleed aperture.

  • Patent number: 9988788
    Abstract: The present disclosure describes a vacuum-excavation apparatus that is connectible to a vehicle. The vacuum-excavation apparatus comprises a vacuum tube with an input end; a vacuum assembly for generating a suction force at the input end and drawing a stream of fluidized debris-material into the vacuum tube. The apparatus also includes a boom assembly for supporting the vacuum tube and a tank for receiving the stream of fluidized debris-material from the vacuum tube. The tank provides a boom mount for pivotally connecting the boom assembly and for providing fluid communication between the vacuum tube and the tank. The apparatus also includes an evacuation tube for providing fluid communication between the tank and the vacuum assembly and for distributing at least a portion of stress-loads that are generated by the boom assembly.

  • Patent number: 9883783
    Abstract: A piezoelectric debris sensor and associated signal processor responsive to debris strikes enable an autonomous or non-autonomous cleaning device to detect the presence of debris and in response, to select a behavioral mode, operational condition or pattern of movement, such as spot coverage or the like. Multiple sensor channels (e.g., left and right) can be used to enable the detection or generation of differential left/right debris signals and thereby enable an autonomous device to steer in the direction of debris.
