Many do not realize, but you have to take into consideration the size of the home, as well as the type of flooring in the house. Every size works better for different size homes. It does not hurt to ask someone in the store that you are buying from either. Many of the vacuum pumps are full sized Edwards vacuum pumps, however they work better in cleaning homes of a larger size. Unfortunately, this is not always a choice, so we have to work with what we have.
Those with a lot of carpeting may want to consider some of the higher end models. The vacuum pumps on the other hand work well for those that have a combination of hardwood floors and carpeting. Usually, they will have more suction power than the vacuums at a lower price. Many of them are not designed so they are easy to use with many different tools, nor do they come fully sealed with the systems that they have. Although easier, they are harder to store and tend to have less power than the upright vacuum pumps.
