they wear out quickly and you will 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 cars serpentine belt pulley system i am 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 are letting dust inside of them or something no other vacuum we have ever had in the last 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 vacuum like brand new again instead of having to go and she will 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 am going to continue buying two of them a year because this vacuum is so awesome
