Systems and method for self-cleaning extraction cleaners, including upright or robot extraction cleaner are provided. In one system, a tray can be provided for docking the extraction cleaner during the self-cleaning mode. The tray may include one or more sprayers for spraying a cleaning fluid toward an agitator of the extraction cleaner. In another system, a nozzle flushing manifold mounted on the nozzle assembly of the extraction cleaner includes a plurality of distributor outlets configured to spray cleaning fluid into the suction pathway.

A pest control device and method and kit for pest control. The pest control includes a main body having a curved shape configured to extend partially or completely around a body of a person, a hose, a collection container operably connected to the hose, and a vacuum mechanism containing a motor. The vacuum mechanism is operably connected to the collection container and the hose. The pest control device also includes a battery operably connected to the vacuum mechanism. The method for pest control includes providing the pest control device, arranging the main body around the body of the person, and activating the vacuum mechanism to suction pests via the hose into the collection container. The kit for pest control includes a main body having a curved shape configured to extend partially or completely around a body of a person, a hose, a collection container, a vacuum mechanism containing a motor, a battery, and a plurality of implements.

[Object] To significantly increased the convenience in suctioning dust on a mop with use of a negative pressure of an electric vacuum cleaner. [Solution] A hose coupling device 10 includes a connecting pipe 14, a branch pipe 15, a ball valve 40. The connecting pipe 14 has openings, one of the openings configured as a first inlet 31 and another one of the openings configured as an outlet 33 communicating with the one of the openings. The branch pipe 15 continues from a lateral surface of the connecting pipe 14 and has an opening configured as a second inlet 32. The ball valve 40 is arranged in a valve box 35 at which the connecting pipe 14 and the branch pipe 15 communicate such that the ball valve 40 is rotatable about a rotation axis corresponding to an axis of the branch pipe 15 while the ball valve 40 remains in contact with an inner wall of the valve box 35. The ball valve 40 includes a first sidewall 41, a second sidewall 42, a third sidewall 43 facing the branch pipe 15, a through hole 45, and a communicating groove 46 extending from the third sidewall 43 to the second sidewall 42. The ball valve 40 is configured to rotate about the rotation axis between a first communicating position to connect the first inlet 31 to the outlet 33 via the through hole 46 and a second communicating position to connect the second inlet 32 to the outlet 33 via the communicating groove 46.

Systems and methods for self-cleaning an extraction cleaner are provided. The extraction cleaner includes a suction nozzle defining a suction pathway, a fluid distributor configured to dispense cleaning fluid to a surface to be cleaned, and a nozzle flushing manifold configured to spray cleaning fluid into the suction pathway of the suction nozzle.

A system includes a vertical frame portion, a horizontal frame portion connected to the vertical frame portion, a motor connected to the vertical frame portion above the horizontal frame portion and including a shaft extending outwardly from the vertical frame portion, and a container having first and second end surfaces, a meshed wall surface extending between the first and second end surfaces, and a lid located on one of the meshed wall surface, the first end surface, and the second end surface. At least one of the first and second end surfaces is removably connected to the shaft. The motor rotates the container relative to the vertical frame portion and the horizontal frame portion. The horizontal frame portion includes a tubular portion including a slit and first and second panels sloping towards the slit to direct material falling from the meshed wall surface of the container towards the slit.
