Unfortunately, the roller on mine arrived non-functional. The handheld part of the vacuum was really nice and has a very strong suction. It was easy to assemble with the included instructions, but once I got it together to use as a stick vacuum, the roller on the bottom would not turn. I tried to troubleshoot and was unable to resolve the issue. Still planning to keep the handheld part as it was a strong little vacuum, but I wish the rest had worked properly.
