We had a Dyson that wore out and was beat up in under 5 years and needed to replace it with something more durable that would still clean well. We had owned a Kirby many years ago but sold it so we knew these were good vacuums. Since the older kids in our house do most of the vacuuming we definitely needed something durable. After reading a detailed comparison of Dyson vs. Kirby we decided to purchase a refurbished Kirby and are very happy with it's performance. I have no worries about letting my children use it and it is cleaning up after our 2 cats, 1 dog and 7 children quite well!
