Rated 3 out of 5 by from Good vacuum cleaner, lousy registration processThe machine is great; the process for registering it is a disaster. The website is confusing, the information required is unnecessarily complex and I could not register my address as Jersey, which is absent from the address drop down even though the Isle of Man is included!
