This product is awesome. It is perfect to keep allergens down in your home. So simple to use. Just place your canister in and tada it’s empty. No mess around your trash can or in the air. The vacuum has an mark to tell you when it is full which makes it easy. My only concern is that the container that comes with the vacuum cannot be emptied on the canister so you must use the one that comes with it. Just a little disappointed in that fact. This product is definitely worth the price however!
