Tristar Vacuums have been around for many years. They were the first vacuum we know of that the vacuum does not loose power as the bag fills up (take that James Dyson). But unlike the Dyson they last for decades. Tristar vacuums are also known as the "Compact Vacuum" brand. It is very common to see one running perfect after 30 years. They are dependable, powerful and super easy (light) to use.
