Tayyab, the fact that it has a broken bin flap and a worn out clutch and brushroll in a relatively short lifespan (lets not forget the Blitz It was one of the last DC14's) says more about the cleaner than any of your praise.
Just to put in perspective, we had 1 cleaner in daily use in a house with 4 kids, 4 cats and 2 adults for 17 years with flawless performance. The only repair it ever had, was a belt replacement. That particular cleaner is still running and is now part of my collection.
My Grandma has 2 dogs. She vacuums daily, sometimes twice. She had 1 cleaner from 1986 - 1997. Despite it being rather battered by the time it was replaced and suffering with broken height adjustment, handle release and broken top cord hook, it still worked after 11 years of twice daily use AND cleaned 2 cars fairly regularly. Since then, she has had 5 Dysons (DC01 standard, DC04 Silver Lime, DC07 Animal, DC15 Animal and a DC27 Animal). None have lasted longer than a few years.
After all that, I think I'll stick with the Sebo.
