I've had mine for about 4 years now and it's fine. Perhaps you weren't emptying the tank often enough, which is when it fills about half way for whatever reason. Otherwise, no idea, sorry.

Having said that, I was expecting wonders from it when I first got it, but the suction isn't as amazing as I thought it would be. I suspect it's just very good suction considering it's bagless. I'm tempted to switch to a Miele as well when my Dyson dies...which it seems to be taking its sweet time doing. But I suspect I will miss not having to pay for cyclical costs (i.e. bags).
