Dude, I just got a Rumba (mine is actually a shark irobot but it's the same as the Rumba) and this thing is awesome. I blazed up some bud from my last crop (Starfighter X Long Bottom Leaf from GLG) and I have been facinated by watching this thing go. I can't believe I have been using a regular vacuum for so long. Technology is pretty badass when used properly. Anyone else have one of these?
