what's there to review? this is a numatic product. I am a professional decorator and we only use numatic hoovers "HENRY". It works every day in terrible conditions and last for about three years. One of our clients had one for 8 years and workded just fine before finally giving in.
try to use a dyson for that long ha ha. I feel sorry for people who buy that overpriced crap only because it has a ball. try to hoover the stairs with it or high shelves, good luck.
george does all that henry does with the bonus of washing your carpet as well. you can suck up spilages, dog wee and unplug a blocked sink. you can buy every part of numatic mashines on ebay. bags are 50p each. use hepa-flow. pro's use these for a reason.
