I don't like wasting time on a bad review, but in this case I have to. I've only had the device for 6 months with light to moderate use and it has stopped working. I understand this is a budget device and I certainly didn't expect it to move mountains, but I did expect it to perform better and not be as troublesome since owning it. I had to take it apart at least once a month to figure out why it wasn't picking up. In only one case was it a clogged hose. I am not aware of any other controls. After I disassembled and reassembled it, it worked again. I've searched the entire block of each and used the recommended packages to find nothing. So each guess is just as good as the other. I've listed the pros and cons below. You may have better luck, but for me I'm just disappointed. anger as value
