The Verdict
I do have to say, this is a cleaning machine. I have used a DC07 and a DC14 in the past, and this one does seem to outclean them for sure. I have a dog that sheds however, which I think is a bad thing with any bagless. When used in a home with no pet hair and little dirt, the problems that I experience with any bagless cleaner would be non-existent. I used the DC17 to vacuum my wall-to-wall plush carpet, and while it did a good job, when emptying the canister, some of the hair did not want to let go, sticking around the fins of the dirt cup. I ended up pulling the final bits of hair from the fins. I would view this as a high maintenance machine as I would want to wash the dirt container after each use, and would definitely want to wash my hands after emptying. I'll probably keep it just to have one in my collection, but would not be a favorite to use as a daily driver. I'll stick to bagged machines for my use. I have a newish Hoover WT bagged upright which cleans very well and doesn't seem to lose suction as the bag fills. I use the allergen filtration Y bags in it, and am very happy with it. Of course from time to time, I do pull out one of my vintage Hoover, Eurekas, Kirbys, etc. just for the nostalgia and vacuuming with a well made metal based vintage vacuum.
