Hoover Windtunnel Bagless Self Propelled U6616-900 Upright Vacuum

This is my Hoover Bagless Twin Chamber upright vacuum (from 2005), model U5752-900, that I bought from a local seller from Offer Up in my area. Since I got 2 non-self propelled Windtunnel Bagless uprights (   • Hoover Windtunnel Bagless Twin Chamber U57...  ) (   • Hoover Windtunnel Bagless U5786-900 Annive...  ), I wanted to know what the self propelled version was like so that's why I wanted this. What makes this different from the non-self propelled variants is not only the obvious self propelled transmission that was added on this, but this also comes an extra feature that allows the brush roll to shut off to safely clean bare floors (if you do it with this vacuum, I recommend turning off the self propelled transmission since it can do burnouts on bare floors). This does come with an on board hose mounted on the side of the machine that is controlled by a mechanical valve down on the head of the vacuum that diverts the suction from either the vacuum head or the hose, all goes through the head when you're cleaning, but when the vacuum is upright, the valve is closed off at the head and all the suction will go through the hose. It features a 12 amp motor with clean air design, and features the twin chamber bagless dirt bin which consists of a filter on one side and a empty section on the other so when the dirt gets pulled in, all of the heavy particles will stay in the empty section of the dust bin, and some particles will get trapped on the filter screen before entering the large pre motor HEPA filter which traps most of the more fine dust particles. The suction is pretty good (not the best in tool mode compared to its bagged counterpart, but respectable), and the airflow is surprisingly amazing for a bagless vacuum (however, I think the non-self propelled version is better), and the agitation is fantastic. My only complaint about this machine is that the twin chamber system is a pain to clean out, especially that large HEPA pre-filter. Overall, I absolutely love this vacuum and is certainly better than anything Hoover makes today.
