Provided are: an aircraft that can fly stably even when water is discharged from a hose installed on the airframe thereof; and an aircraft system that uses the aircraft. This aircraft system comprises: a master aircraft 10; three slave aircrafts 20; and a remote control device 30 that is for making the aircraft fly as a unit. Each slave aircraft 20 has: four rotary blade portions that have propellers 221; and a suspending means 23 that is for suspending a prescribed part of a hose 50 that is for discharging water. The master aircraft has: four first rotary blade portions that have first propellers 121 that have been arranged to rotate in a horizontal plane; four second rotary blade portions that have second propellers 131 that have been arranged to rotate in a vertical plane; and a nozzle 15 on which a tip end part of the hose 50 is installed. The direction of the center axis of the nozzle 15 is parallel to the direction of the rotational axes of the second propellers 131.

A reconfigurable surface cleaning apparatus has a removable portable surface cleaning unit wherein the portable surface cleaning unit has upper and lower longitudinally spaced apart mounting members.

A tool that is either hand-guided, or machine-guided, for performing surface treatments, such as mopping, of overhead surfaces includes a head for carrying an agitator having a generally planar face that is applied against the overhead surface being treated in uses. A transmission transmits power from a drive motor to the agitator, and an interface on the head is provided for connection to a mounting device by which the head is oriented and guided.

An awning cleaning tool for cleaning awnings and other structures employing awning-like material. In one implementation, the awning cleaning tool includes a cleaning head unit having a squeegee-like leak guard, one or more powered brushes, a row of water-detergent applicator nozzles, and an elongated extraction port. The awning cleaning tool also includes an elongated extension and a control handle. During cleaning, a water-detergent mixture is sprayed via the nozzles onto the top surface of the awning and the powered brushes work the water-detergent mixture into the material of the awning to dislodge the dirt and debris. The used water-detergent mixture, dirt and debris are extracted via the extraction port. Any excess water-detergent mixture is captured by the leak guard so that it does not run down and off the awning.

A reconfigurable surface cleaning apparatus has a surface cleaning head, a support structure moveably mounted to the surface cleaning head between a storage position and a floor cleaning position and a portable cleaning unit removably mountable to the support structure. The support structure has a lower portion and an upper portion, the upper portion is rotationally mounted to the lower portion between a first configuration and a second configuration wherein, when the support structure is in the storage position and the support structure is in the first configuration, the upper portion extends upwardly from and lower portion and, when the support structure is in the storage position and the support structure is moved to the second configuration, the upper portion is rotated forwardly.

The present invention discloses a separator, including a top plate, a bottom plate, and a plurality of grid bars, wherein both the top plate and the bottom plate are circular in shape, and the diameter of the top plate is less than that of the bottom plate; the separator has a motor connection portion, and a center of the motor connection portion coincides with a rotation center of the separator; and the plurality of grid bars are circumferentially spaced between the top plate and the bottom plate. The present invention further discloses a cleaner with the above separator. The separator has large air inhaling force, and makes a drastic change to a speed of inhaled garbage. When the initial speed of the separator is low, it is not easy to inhale garbage. This improves a garbage separation effect without affecting the service life of a filter element.
