A submersible vacuum cleaner for facilitating the removal of material 6 deposited at the bottom of a body of liquid 8, such as a pond or fish tank, comprises a suction pump assembly 1 associated with a suction nozzle 5 which is mounted to a handle 3 by which a user can manipulate the vacuum cleaner. In use the suction pump assembly 1 is totally submerged within the body of liquid 8. Means 4, such as a float or other buoyancy device, may be provided on the suction pump 1 so that its weight along with that of the suction nozzle 5 is counterbalanced so that handling is easier. The handle 3 preferably includes a hollow tube 9, 10 in which the pump 1 is mounted. The tube 9, 10 also provides a conduit for guiding material entering the suction nozzle 5 to a receiving location remote from the volume of water 8. The handle 3 is also preferably telescopic so that it can be extended depending on the depth of the body of liquid 8. |
