Firstly, the cost is a third of the price than what Dyson charges. Wow! Secondly, comes with 2 rollers where Dyson comes with one roller only. Bonus! So I decided to purchase this one after searching through 鶹 and this manufacture was my purchase choice. Arrived within a couple of days in perfect order and easy to install. The vacuum head is much lighter than Dyson which for me is now not a struggle when pushing and pulling the vacuum back and forth. It has lights on the front where the Dyson does not. The suction is works great. Dyson one maybe a tiny bit stronger but not a real game changer. But having said that I can adjust the suction on the vacuum head to be stronger suction if need be but honestly Flylink vacuum head works great. There is no weird noises coming from the head and runs smoothly. The fit is great and no struggle taking it on or off. I am pleased with this purchase and would definitely recommend. Also, there is a one year warranty.
