Having bought this to replace a very aged cylinder vacuum cleaner, this is heaven! As a woman of a certain age who sheds her long grey hair at an alarming rate and also as an owner of two snow Bengal cats who seem to be in a constant state of moult, I was sick of untangling hair from the cleaning heads on my previous cleaner. This is bliss! I couldn't believe how clean the carpets and floors are now. At first I spotted hair tangling around the roller on this one. too, but did as the manual instructed and ran it over a patch of hard floor and voila! All clear again. I was also pleased at how simple it is to change the power level for different surfaces. Great for clearing stray cat litter off tiled floors. I never thought I'd see the day when 60 minutes run time seems awfully short when you are deep into cleaning mode (I'm not terribly into doing domestic), but maybe I was getting a bit carried away given how simple and useful the conversion from upright and handheld was when the spring sunshine revealed I seem to have more cobwebs in high corners than Miss Haversham ever had! Well, used to have before I bought my Shark. Hopefully others will find it as quiet, versatile and efficient as I have. It's so worth the money.
