When I was getting my DC07's yesterday, the chap selling them asked me if I knew what these numbers mean.
I said what numbers? He then showed me. On the back of each DC07 Cyclone, by the output hole is a number moulded into the plastic. We found a 1, 2 and 3.
Anyone know the difference? Going by the machines they came off 1 was early, then 2 had the solid colour base but I imagine the mod to remove the bits of plastic ontop of the cyclones then 3 had the clear base, so the later ones.
