I purchased online when delivered was left at the front of my garage/house, good thing I was home because I'm sure someone would have taken it, since large box left in clear vision of the street! Unpacked and first thing figured out I was missing part with bolt and locknut. I was able to get myself to continue with the assembly process. As others have stated the instructions for assembly are not helpful at all! Hope you have some mechanical knowledge to assemble because you will need it. Then after assembly I went to use it, well I did not check to see if what was factory pre-assemble was all tight. Be sure to do that because in my case one of the brushes ended up in the hopper because they were are loose. Had to stop re-assemble that and make sure everything was tight that was pre-assembled.
