Abstract

A wet and dry pick-up attachment device (1100) for a conventional vacuum cleaner. The attachment device (1100) comprises attachment means (1128) suitable for coupling with a flexible hose (1201) of a conventional vacuum cleaner. The device comprises an inlet nozzle (1101) to allow fluid to be drawn into the device by the suction airflow created by the vacuum cleaner and a liquid storage tank (1111) to store liquid drawn into the device by the suction airflow. Separation means are provided to separate liquid drawn into the device (1100) from the airflow and to prevent the liquid from passing downstream of the attachment device (1100) to the vacuum cleaner.

5 The device as claimed in any preceeding claim further comprising a secondary filter positioned at least partially downstream of said chamber, said 0 secondary filter configured to inhibit liquid within said suction airflow passing downstream of said chamber.
6. The device as claimed in any preceeding claim further comprising a ball-bearing moveably housed within said primary filter, said ball-bearing 5 configured to roll within said filter to contact said chamber outlet to prevent said suction airflow and said liquid from passing downstream of said chamber in response to said device being inverted or partially inverted.
7. The device as claimed in any preceding claim further comprising at o least one U-bend hose portion positioned in airflow communication between said inlet nozzle and said storage tank.
30
8. The device as claimed in any preceding claim wherein said storage tank comprises baffle means positioned internally within said storage tank and configured to inhibit the flow of liquid between a front and a rear portion of said storage tank.
9. The device as claimed in any preceding claim further comprising at least one bleed valve configured to allow air to be bled into said device.
10. The device as claimed in claim 9 wherein said device comprises a housing body extending between said inlet nozzle and said means to attach said device to said vacuum cleaner wherein said at least one bleed valve comprises at least one aperture positioned at said housing body.
11. The device as claimed in any preceding claim further comprising a float-type valve positioned within said storage tank, said valve configured to prevent said storage tank overfilling with liquid by terminating said suction airflow through said storage tank in response to liquid within said region of said device contacting said valve.
12. The device as claimed in any preceding claim wherein said storage tank comprises a substantially planar external base.
13. The device as claimed in any preceding claim wherein said storage tank comprises at least one drain tap.
