Query: Eureka - too much work!

After reading all the reviews I could find I bought this vacuum at Walmart last year. It has turned into a family joke because it is such a nightmare to use. It is unbelievably heavy and cumbersome. My carpets are two years old and even with vacuuming weekly I have to clean the filters every couple of weeks. It often cuts off after a few minutes of vacuuming from (?)overheating despite cleaning every filter on the thing - which is messy and a pain in the neck. I've had it in for service twice but each time they tell me "nothing is wrong". What is wrong is that I purchased the wrong vacuum. Steer clear- there are better vacuums on the market that weigh less, do a better job. I'm ashamed to give mine away to some other poor soul.
