No vacuum tube between the canister and the suction pump is necessary - just click-in-place and go.  A clean and efficient solution, a used canister can be replaced quickly with a new one when suctioning is completed. The canister is sealed, with an internal filter. The filter automatically stops suction/flow when the canister is full or the filter becomes saturated if the unit tips onto its side during use. Once wet the filter forms a gel which prevents ingress of fluid into the pump.
