Review title is They wear out quickly and you'll be buying two a year. [SEP] My review is for this vacuum cleaning a house that has Michigan sand that keeps being brought in from the dogs and even the human shoes. The carpet is a tight knurled dark pattern, and also a couple of area rugs that are low pile, and a wood floor. Eventually the vacuum started making noise after a week. Little tiny noises here and there that reminds you of a bearing that starts making noise on your car's serpentine belt pulley system. I'm a mechanic, so when I heard that noise I instantly knew it was a bearing in the spindle. Or time to get louder and louder and I had to replace it and I bought it Factory Direct. And then that was great and quiet for about a week, and then a few noises and trips here and there of the bearing. Obviously these bearings suck and they're letting dust inside of them or something. No other vacuum we've ever had in the last 25 years in this house has had a problem with the bearings going out on the spindles. And look how many reviews there are. Plenty of high reviews for people that are just glad to have a roller that made their $250 vacuum like brand new again instead of having to go and she'll of a couple hundred dollars more for another vacuum. But the sad truth of it, is that it is a low-quality part even though it is Factory Direct. This is the real deal. No second-hand plastic injection mold factory making knockoffs. It is the real deal. And the real deal just sucks. But I'm going to continue buying two of them a year because this vacuum is so awesome.
