I bought this vacuum about 3 years ago. It works great. I never had any of the belt slippage that some are saying here. Only thing I have to do is occasionally clean the tubes where there is a loss of suction power (this may involve some dis-assembly or using a snake tool). I also need to replace the HEPA filter (never did it yet so got some life out of it). What turned me on the the vacuum was 2 things. 1st, Consumer Reports had it at a very high suction rating. 2nd, it was 1/3 the cost of other vacuums. I figure if it breaks after a few years, I would just buy another one and still be up in $$.
The design team for this vacuum cleaner should simply be fired. It has so many basic engineering flaws that prevent reliable long-term use. There is a "crook" in the plastic attachment coming out of the roller suction (and before the flexible hose) that catches pet hair and soon clogs the hose. Even when this crook is cleared the hose itself was so crammed with pet hair (maybe from the way the accordian hose is designed) that that also gets clogged (so badly in fact that we had to use a broom handle to ream out the hair after we detached the hose). Suction may initially test sufficiently but over time the suction on this vacuum cleaner seems to diminish even with maintenance of the parts. Bottom line: You should not have to disassemble and clean the hose parts after a few uses. If you have pets, especially, this vacuum cleaner is not for you.
The body of the vacuum is very clumsy, can't fit into small spaces, made of cheap plastic, the hose suction is terrible, and to clean it is a mess.
Strong suction.Easy to handle & no rewinding of the cord.
