I absolutely loved this vacuum until the roller brush melted and stopped working. I didn't even have this vacuum for 6 months. It picks up so much dirt and hair and it's incredibly light weight too! So easy to manage and use on the stairs which was my favorite. After a few months it started making a burning smell which started off faint. I'd clean it out making sure nothing was clogged and nothing ever was. Eventually the roller just completely melted and you can't use it without it making the loudest noise and the smell of burning plastic. Hopefully they put the brush back in stock so I can order the replacement part.
