  • a side wall 36 of the clean water vessel 22 forms an obstruction plate, against which air and entrained water from the suction pipe 12 impinges. Water that hits the side wall 36 runs down the side wall 36 and drips to the bottom of the body section 16.
  • Such use of the side wall 36 beneficially removes water from the air flow so that only air is sucked into the port 18, after filtration by the coarse absorbent filter in the cavity 34.

  • a period of approximately thirty seconds elapses to allow for the vacuum pressure to build and to allow for water to be pulled along the tube 14 from the clean water vessel 22.
  • the thirty second period is chosen to allow free wine 40 to be drawn up by the vacuum before a detergent is released as will be described below. .
  • the period of thirty seconds is chosen for convenience, but of course could be varied.
  • the length of time taken for water to be drawn from the clean water vessel 22 is based on the length of the water supply tube 14, its 5 diameter and any constriction therein. Thus, suitable variation of these factors can be made to achieve a desired length of time between initial placement of the head section 10 on the soiled carpet 38 or other material and the arrival of clean water at the head section 10.0
  • the water supply tube 14 enters a cavity 50 of the head section 10, in which cavity 50 is located a cleaning product 49, such as a suitable detergent.
  • the clean water from the clean water vessel 22 causes the cleaning product5 to be either dissolved or liquefied and is then carried into the centre section 48 via an opening 52, as shown in Figure 4.

  • the bristles 54 may be moulded into the centre section 48 or may be inserted after production5 of the remainder of the head section 10.
  • the base of the body section 16 should be sufficiently sized to take all of the water from the clean water vessel 22 and also the cleaning product from the cavity 50.
  • the head section 10 is made of a flexible or resilient material, possibly out of synthetic or natural rubber or a suitable thermoplastic elastomer.
  • the head section 10 may be in the form of a cartridge which is replaceable after each use, with the cavity 50 in the cartridge carrying a fresh supply of cleaning product 49.

  • the water vessel 22 would typically be filled by removal of the water vessel 22 and filling it from a tap or the like.
  • An alternative arrangement for the head section 10 is to have the cavity 50 forming a removable cartridge for containing the cleaning product and for replacement by a fresh cartridge after use of the cleaning product 49 therein. This would leave the remainder of the head section 10 for repeated use attached to the vacuum tube 12.
  • the cartridge of cleaning product 49 would have a connection for the water supply tube 14.

  • the connections between the two would still be the same in that a flow path from a portion corresponding to the body section 16 to a portion corresponding to the head section 10 and back from that section to the body section 16 would still be present, although a user would manipulate the combined head and body section in order to clean the carpet 38 or other material as described above.
  • the cleaning device described herein is of particular use for cleaning spills or stains, such as wine stains as described above.

  • the cleaning device described herein has particular advantages in allowing spills to be cleaned using a simple attachment to a vacuum cleaner which can easily filled with a small amount of water to provide the necessary cleaning of a relatively small spill .
  • the provision of a cavity for including cleaning product provides additional advantages over simply using water to clean a spill .
  • the provision of a cartridge of cleaning product allows for easy replacement and easy repeated use of the cleaning device .
