Dirt, dust, and debris picked up by your Vacuflo central vacuum system are deposited into the dirt canister. The Vacuflo dirt canisters are attached to the bottom of the power unit and will need to be emptied periodically. As time does by some canisters can become weak and break or crack. Here you will find replacement dirt canisters for your Vacuflo central vacuum system. If you do not see the canister you need, please call 1-800-322-3965 and one of our central vacuum experts will be happy to assist you.
