摘要： An extractor cleaning machine includes a supply tank configured to store a cleaning fluid and a base configured to be movable along a surface to be cleaned. The base includes a suction nozzle and an aperture configured to spray the cleaning fluid onto the surface. The extractor cleaning machine also includes a recovery tank in fluid communication with the suction nozzle and a suction source in fluid communication with the suction nozzle and the recovery tank. The suction source is configured to draw the cleaning fluid through the suction nozzle and into the recovery tank. The extractor cleaning machine further includes a body pivotally coupled to the base between an upright position and an inclined position. The body includes an outlet in fluid communication with the suction source such that an airflow generated by the suction source is discharged from the outlet toward the surface.

摘要： A tool for cleaning gutters includes a specialized nozzle that may be attached to a leaf blower via a set of rigid tubing. The nozzle transitions from a tubular shape into a mouth-like opening with a first projection in opposed, spaced relation to a second projection. The tool is particularly well suited to removing debris from gutters with the nozzle in contact with a gutter and made to expel high-velocity air.

摘要： A broom tube assembly for dislodging debris while employing a leaf blower includes an air tube that is mountable on an output of a leaf blower. A broom is provided and the broom is coupled to the air tube. The broom frictionally engages a surface being cleaned when the air tube is directed toward the surface. In this way the broom can dislodge debris for blowing the debris with the leaf blower. A plurality of brackets is each positioned around the handle. Each of the brackets engages the air tube for retaining the handle on the air tube.

摘要： A needle screw fitted to a compressed fluid supply part that is provided on a nozzle main body of a dust removing device adjusts the jet flow rate of a first compressed fluid from a jet nozzle by adjusting the flow path area of a first fluid supply path. Meanwhile, the suction flow rate of a second compressed fluid to be discharged into a discharge flow path is adjusted by adjusting the flow path area of a second fluid supply path by turning a nozzle main body-side adjustment screw that is provided on the nozzle main body and a suction nozzle-side adjustment screw that is provided on a suction nozzle.

摘要： A cleaning apparatus for use by hand and/or with a robotic device includes a nozzle that expels fluid, air or liquid, out of an open end of a housing of the cleaning apparatus. Simultaneously, a vacuum device is suctioning debris through the housing and into a vacuum port. The simultaneous use of suction and expelled fluid through a single apparatus generates turbulent airflow and effectively loosens and removes debris attached to surfaces without the need for the housing to contact the surfaces.

摘要： Debris removal apparatus, systems, and methods of using the same are described. An example debris removal apparatus includes a shaft, an energy source, a motor, a fan attached to the motor, and a switch. The shaft has a lengthwise axis, a first end, a second end, a first portion, a second portion, a third portion and defines an opening on the second end, a passageway in fluid communication with the opening, and a plurality of inlet openings on the third portion of the shaft in fluid communication with the passageway. The motor is operatively connected to the energy source and disposed between the plurality of inlet openings and the second end of the shaft. The motor has a lengthwise axis extending through a drive shaft. The lengthwise axis of the motor is parallel to the lengthwise axis of the shaft. The switch is operatively connected to the motor.
