with young children who play on the floor and live closer to the ground that we, adults, plus a cat at home, we needed a competitive vacuum that makes sense over time, because the weak death machines is that they age well! First good point for dyson, five years warranty (which also pleases with no more major retailers therefore can not add their own extended warranty!) is that they are sure of the quality of their products! I would not make the details of the qualities of the bagless vacuum, tv pub (which has dyson most!) made many converts. These vacuum cleaners are quite expensive but no to renew all four mornings! saw extensive use almost every day (or even two times a day on weekends) it holds the road well, and in terms of anti allergen look I can only say that my son has less sneezing, he who is weak bronchi.
