Opinions Needed, STAT

I don't handle it well when things don't work properly, and my vacuum has not been working properly (at least, not 100% of the time) for the last many months.  And, just now while trying to vacuum and getting more and more p*ssed off and ready to take my anger out on the dogs or smash into a coffee table or chair with the stupid machine and accidentally break something I treasure, I decided to come here to vent!

So, I'd like to know what vacuum YOU have and why you like it (or don't)!  My two requirements in a new one are a lighted dirt detector (once you have one, you can never go back) and a bag-less system.  I've always had a vacuum with replaceable / disposable bags, but getting a bag-less one that you empty yourself and re-use time and time again only seems to make sense.  Besides, I'll be able to see how fast it fills up . . . which is, I suspect, one of the problems with my current vacuum.  It seems that the bags fill up WAY too fast, but I refuse to change it out within only a month or so from the last change!

Please, HELP!  I will order up a new one the instant you all help me make the best decision!


Note:  this is an upright vacuum for the rugs / carpets that I need.  I use a ShopVac for the hard floor areas.
