ABSTRACT:
A vacuum cleaner assembly including a multiplicity of vacuum cleaner canister units each of which has a filter for receiving dirty fluid sucked into the canister unit and is configured such that two suction forces operate on each canister unit, with one suction force pulling fluid onto the filter and being of greater force than the second suction force pulling fluid away from the filter and pulling it out of the canister unit to an adjacent canister unit, the filter in each canister unit located in a removable compartment which can be removed when the compartment is filled with dirt, and valve means to turn off the flow into a canister unit after its compartment has been filled with dirt while permitting the vacuum cleaner to continue running and directing the flow of dirty fluid to adjacent cannister units with uninterrupted and undiminished suction power.
