I have a Dyson 8 Tier. Since I bought it two years ago I've had so many problems and now it just won't work or even charge. I will bring it back to the store tomorrow. The only thing I found handy was that it was wireless. You can trust this company for the price, they must have the best and most functional vacuum cleaner. When it worked, it ran so fast you have to charge it again. And the dust particles remain and do not move in the head. It also works and stops at the bus stop. I'm doing a filter cleaning step and it's still giving me trouble to use. I'm tired of not being able to finish my work and get on with my day. Don't buy this. My friend also had a lot of problems with the Dyson vacuum cleaner.
