I was having problems with the wheel on my robot vacuum and didn't want to pay to send it somewhere for repairs. I found some YouTube videos of people just replacing the wheel assembly so I decided to give it a try. It's a lot cheaper than sending it in for repairs. I bought both sides and it's been working ever since.
