  • the outer diameter of the output cap 78 is press fit into the opening 98 to secure the output cap 78 to the container housing.
  • first take-up tube 120 Coupled to an opposite side of the first tube adapter 118 is a first take-up tube 120. Coupled to the opposite end of the first take-up tube 120 is a first filter 122. It should be appreciated that a first fluid path is defined from the interior of the container 64 to the disk valve 102 by the first filter 122, first take-up tube 120, the port 116, the directional chamber 108 and the conduit 106.
  • a fluid pathway may be formed between the input chamber 126 and the directional chamber 108 based on the position of the spherical member 114.
  • the valve assembly 92 When the valve assembly 92 is in a first position (e.g. with the cleaning element vertically above the container 64), the spherical member 114 will move against the second inlet 110 as shown in FIG. 15C to block fluid flow from the ball valve chamber 112 to the directional chamber 108 creating a fluid pathway 123 from the filter 122 to the disk valve 102.
  • the valve assembly is in a second position (e.g.
  • Coupled to the input tube member 124 is a second take-up tube 132 via a second tube adapter 133. Coupled to an opposite end of the second take-up tube 132 is a second filter 134. It should be appreciated that when the valve assembly 92 is in the second position as shown in FIG. 15B (e.g. the inlets 130 are in fluid communication with the directional chamber 108), a second fluid pathway 135 is defined from the interior of the container 64 to the disk valve 102 by the second filter 134, second take-up tube 132, the input chamber 126, the passageway 128, the inlets 130, the ball valve chamber 112,through inlet 110, the directional chamber 108, and the conduit 106.
  • the storage container 64 further includes one or more vents 134 that provide an air pathway from the environment to the interior of container 64.
  • the vent 134 includes a slit 135 that is configured in a normally closed position (e.g. no air flow). In response to a pressure within the interior 136, falling below a threshold, a portion of the vent 134 deflects, allowing air flow into the interior 136. It should be appreciated that the vent 134 prevents the generation of low pressures (e.g. below ambient) that could interfere with the operation of the pump 66.
  • valve assembly 92 When the valve assembly 92 is disposed within the interior 136 ( FIG. 9B ) of the container 64, with the pivot arm 82 coupled to the container 64, the valve assembly 92 extends along the length of the container 64 with the first filter 122 being disposed adjacent the opening 138 that is enclosed by the cap 74 and the second filter 134 being arranged adjacent the opposite end 76. As will be discussed in more detail herein, the valve assembly 92 is configured to allow the cleaning fluid storage and dispensing assembly 60 to draw cleaning fluid from the interior 136 with the device 20 positioned in any orientation (e.g. cleaning element 42 on a horizontal surface, a vertical surface, an angled surface, a floor, a wall, or a ceiling).
  • any orientation e.g. cleaning element 42 on a horizontal surface, a vertical surface, an angled surface, a floor, a wall, or a ceiling.
  • container 64 can be permanently connected via a tube (tether) such that no pivot arm 82 is provided.
  • the tube 70 connects directly to the output cap 78 and is sized long enough so that the end user can remove the container from the housing to fill the bottle.
  • the user first fills the container 64 with the desired cleaning fluid.
  • the container 64 may be filled with the cleaning fluid and coupled to the pivot arm 82, or external to the device 20.
  • the user installs the container 64 (if filled externally) by sliding the pivot arm 82 into the opening 80 in output cap 78.
  • the seal 90 engages the inner surface of the opening 80 to both seal and secure the output cap 78 to the pivot arm 82.
  • the coupling of the container 64 to the pivot arm 82 may be performed with the pivot arm 82 rotated relative to a longitudinal axis of the housing 36 or with the pivot arm 82 in the operating position.
  • the pivot arm 82 can be rotated to the operating position ( FIG. 5 ) to position the container 64 within the housing 36, and the cover 50 may be installed to enclose the container 64 within the housing 36.
  • the valve assembly 92 When the user positions the device 20 with the cleaning element 46 vertically below pole 22, such as when cleaning a floor or the bottom of a pane of glass from a standing position for example, the valve assembly 92 is oriented with the second filter 134 being vertically lower than the first filter 122. It should be appreciated that when in this position, the spherical member 114 is positioned with the inlets 130 in an "open" configuration to allow a fluid path from the second filter 134 to the disk valve 102. It should further be appreciated that any cleaning fluid in the container 64 will flow towards the end 76 under the influence of gravity. Thus, unless the storage container 64 is substantially filled with cleaning fluid, the first filter 122 will not be in fluid communication with the cleaning fluid, while the second filter 134 will be in fluid communication with the cleaning fluid.
  • the second filter 134 may no longer be in fluid communication with the cleaning fluid since the cleaning fluid will flow to the end of the storage container 64 adjacent the cap 74. It should be appreciated that this orientation may occur when the user is cleaning a higher section of a wall or window, or the ceiling for example.
  • the first filter 122 will be in fluid communication with the cleaning solution.
  • the spherical member 114 will move against the inlet 110 to seal the directional chamber 108 from the ball valve chamber 112.
