Dyson made vacuums and it feels they may be more expensive than average, but their prices are justified (well they are a little cheaper on Amazon or other website or in-store price is often exaggerated ) but its aspiration is excellent. There is a multitude of accessory (depending on the model you get more or less) to make your life easier and vacuuming in good condition. It is a not very heavy vacuum cleaner that makes a bit of noise in general and yes it's a little noise when vacuuming (the quietest found are 62dB, it must be around of 78dB). It sucks very well, it goes everywhere, the brush glides well, it empties easily, it is VERY SOLID, a criterion that is important (it does not fall into pieces), these wheels are handy and does not knock you all the time in the feet when you advance a little. It disassembles has multiple locations on the handle, the handle, brush or hose. Many tests exist measuring the suction speed, consumption, noise, strength and Dyson vacuums are really good (the only point that can block some is noise). For my part I am really delighted.
