I used to spend about $80 on a vacuum cleaner but had to replace it about every two years. I got fed up and bought a shark navigator 2 years ago. I think it was between $150 and $200 but it has a five year warranty on it so I thought I would try it. It has surpassed all my expectations. I rant and rave about this vacuum. It is absolutely the best investment I have made. It is light weight, easy to use, easy to clean, and the suction power on it is unreal. Every cleaning lady I have used in the past 2 years has agreed it is an excellent vaccum cleaner with very strong suction power. Worth every penny. Highly recommended especially because of the price compared to a dyson. Oh and as a bonus it can be used on floors as well as carpets and work equally well on both.
