I bought a Dyson Motorhead V7 from Revain on May 18th 2018. After only 3 months I started smelling a terrible odor (smell) from the detergent. It smells so bad I don't even feel like I cleaned my house! Now I can't get rid of that smell! Also, since a few days I can't remove the cyclone and part of the bunker, I can't even open the lid and I can't clean inside! So I can't use my vacuum cleaner at all! I contacted support via email but they don't help at all! I paid over $300 and now it's just bullshit. So if you buy and something goes wrong with the vacuum cleaner, they won't help you! Stay away.
