Pros: Great Suction
Cons: THE WORST Belt design--don't buy!
I bought the Eureka Boss Smartvac 4870 one week ago. This was purchased based on Consumer Report's rating. I have used it 3 times since purchase. While I was initially very impressed with it's suction, that soon faded as I used it today. I noticed a burning smell while vacuuming a low pile carpet and then noticed that the beater brush was not rotating. Took a look underneath and sure enough the belt was broken. Many people have stated that the belts on this vacuum are worthless...I'd say a week of use is pretty worthless!! Replaced the belt and the brush still won't turn. Open things back up and notice that the spring that switches from floor to carpet has popped out of it's channel. Can't get it back in without total disassembly. The only saving grace is that it was bought at Costco which has a very good return policy....So back it goes! Very poor design of the belt system and also the handle release switch.
