Bests & Worsts Reviews from Amazon

I'm very frustrated with Samsung service on this device. I bought two of them and had to send one in for service at about 6 months as it just stopped working. About 10 days past the 1 year warranty, the rollers on the bottom have worn out and they appear to be designed as a wear item that won't last more than a year with regular use. I spent an hour on the phone and was told I would need to mail it in as the rollers are not something I can replace. Then I was told I could contact Samsung Parts as I was days past the 1 year warranty. The rollers pop in and out and are a $1 wear item that Samsung pretty much make impossible to get. Literally a 2 second replacement. My vacuum can't be used now. Sending it in for service is completely ludicrous and would be very expensive. The people they have on the phones have no ability to help you or do much more than repeat a script over and over again. I then went to the samsungparts.com website to attempt to get the part. The site provides no diagram to assist in locating the part and almost all of the parts say photo coming and have no useful information. I did find the optionto buy a service manual that would let me know the roller part number but they want you to pay for that. I ended up ordering the shaft roller for this model based on the extremely limited information that is available and that the service department is unable or completely unwilling to even identity the part number. Two weeks later a bag of just shafts arrived when all I needed is the roller. I've emailed Samsung Parts and expect they will tell me to ship it back at my expense and do nothing to help. The shipping costs are absurd for a tiny little part that should cost about $1. So I have $2,000 in robot vacuums that I can't use because of a $1 wear part that Samsung and Samsung parts make incredibly difficult to get. I hate buying something that is suppose to be the best, stepping up to pay for it and feeling ripped off and treated poorly.
