The processor 82 is programmed such that the processor 82 is configured to receive commands from the remote electronic device and to selectively transmit images from the camera 80 to the remote electronic device. A device holder 92 is coupled to the base tube 12 and is shaped such that the device holder 92 is configured for holding the remote electronic device. The device holder 92 comprises a panel 94 and a pair of opposed clips 96. The pair of opposed clips 96 is coupled to the panel 94 and is configured to hold the remote electronic device therebetween via a snap fit.


A tube valve 98 is coupled to the base tube 12 and is movable between an open position and a closed position. The tube valve 98 is configured to permit the fluid 116 to travel through the pair of base channels 14 only when the tube valve 98 is positioned in the open position.


A pair of cleaning fluid containers 100 is mounted to the base tube 12. Each cleaning fluid container 100 of the pair of cleaning fluid containers 100 is configured to contain cleaning fluid and is in fluid communication with an associated base channel 14 of the pair of base channels 14. Each one of a pair of cleaning fluid valves 102 is coupled to an associated cleaning fluid container 100 of the pair of cleaning fluid containers 100. Each cleaning fluid valve 102 of the pair of cleaning fluid valves 102 is movable between an open position and a closed position and is configured to permit the cleaning fluid to move from the associated cleaning fluid container 100 to an associated base channel 14 of the pair of base channels 14 only when the cleaning fluid valve 102 is positioned in the open position. The cleaning fluid containers 100 may contain any fluid for use in cleaning surfaces such as soap, a degreasing agent, a rinsing agent, a surfactant, a foaming agent, or the like.


A handle 104 is mounted on the base tube 12. The handle 104 is movable along the base tube 12 between the first end 16 and the second end 18 and is securable in a selected position along the base tube 12. The handle 104 comprises an inner member 106 and an outer member 108. The outer member 108 is movable with respect to the inner member 106 to clamp the inner member 106 against the base tube 12. The outer member 108 has internal threads 112 which engage external threads 110 of the inner member 106 such that the outer member 108 moves linearly with respect to the inner member 106 when rotated with respect to the inner member 106. The inner member 106 comprises clamping fins 114 which the outer member 108 urges to clamp against the base tube 12 when the outer member 108 is urged against the clamping fins 114.


In use, the selected attachment is attached to either one of the base tube 12 and the extension tube 20. The selected attachment may be used to scrub, wipe, or otherwise physically clean surfaces. The extension tube 20 is particularly advantageous in permitting a user 120 positioned below an upper surface 124 of a structure 122 to clean the upper surface 124. The camera 80 may be used to view the upper surface 124 during this process. Another display screen may also be used to connect to the camera 80 and view the images recorded by the camera 80. Connections between the remote electronic device or other display screen to the processor 82 may also be wired.


The fluid 116, such as water or a cleaning solution, may be urged through the base tube 12 and the selected attachment toward a surface to be cleaned. When the selected attachment is attached to the extension tube 20 and the extension tube 20 is attached to the base tube 12, the fluid 116 may be directed from the first end 16 of the base tube 12, through the base tube 12, the extension tube 20, and the selected attachment to the surface to be cleaned. The stationary scrubber attachment 42 and the rotating scrubber attachment 64 may be alternately used to facilitate directing the fluid 116 from the extension tube 20 to the surface to be cleaned. The wiper attachment 58 as depicted in FIG. 11 does not have a conduit for transferring the fluid 116 but may have such a conduit in some embodiments.


The cleaning fluid containers 100 may contain distinct cleaning fluids which are able to be dispensed into associated ones of the pair of base channels 14, preventing any mixing of the cleaning fluids that could result until the cleaning fluids reach the selected attachment. Selected fluids for the distinct cleaning fluids may be used which are intended to be mixed at the selected attachment or which are meant to be used independently of each other.
