For years I used a central vaccum system until it broke down. I researched many products and considered their reviews and prices. So when i settled on a PacVac I was confident it was a good choice. I have not been let down and can only say in terms of bang for buck how pleased I am with the product. Easy to use, quiet, i can reach every corner of a two story house without changing powerpoints. The suction is huge - gets eveything. Thanks for a great product
