Based on whole dyson experience not just app. In 18 months machine broke down 3x. Replaced 2 times and repaired once But took almost a month each time. Last time when repair was book, they kept telling me it's stolen Machine and they cannot fix it. Eventually they did but kept power adapter and remote. When I called, they said will ship new. But it's out of stock so machine is still unusable. CS reached out to resolve dis satisfaction and end up saying he can't do anything. HIGHLY NOT RECOMMEND
