For those of you looking at purchasing a new vacuum take a look at the new Shark Rotary vacuum its a great bit of kit, a bit plasticy as they tend to be now days but for performance its very good and has a fantastic power brush attachment for upholstery which is far and away the best I have seen you can also detach the motor and carry it over your shoulder to do stairs curtains etc.
The Shark Vacuum consistently comes out on top in the U.S. and at £210 or there abouts its pretty good value.I bought one last week as we have a new grandson and I want the carpets as dust free as possible. I used our old hoover on the carpet first and then went over it with the Shark and it was shocking how much extra it took from the pile.
The really neat thing about is its completely sealed so for allergies its fantastic as on its own the HEPPA filter can not do the job properly of holding in all allergens, we don't do much carpet cleaning now days but if we were I would definitely use this vacuum from now on all jobs.
just read that again and it looks like an advertisement, its not
