this Dyson is my second one, the first lasted 6 years and the only reason I got rid of it was that some of the plastic tubing was starting to rip. The first thing I noticed about this Dyson is it's much lighter than my old one and also quieter. Sometimes with the old one I felt like my arm would fall off after doing the whole house but this one really makes hoovering easier. The suction is still good and the quality of suction stays the same whether you have it on carpet or hard floor option. Am still not sure if its lighter weight will mean its made from not so good quality parts, but its doing a good job at the moment. It has an anti allergy filter which is great, we have a dog that my sister is allergic to and when we hoover before she comes round it prevents her from suffering as much.
