Big news for collectors - big yawn for the rest of the marke
I think that's partly because they were marketed so poorly, if at all. The new Constellation really had no presence in any of the big box stores. I think that if they would have gotten it into a big-box, especially Target -- it could have been much bigger and more successful. At $199, it was a pretty good value. Super long cord, metal construction, a TON of power, HEPA bags... and just so different. Granted, it does blow the dust around, and the turbo-nozzle is... well, a turbo nozzle. Nonetheless, I think for how different it was, it would have done well.
The celebrities are so much louder because of that tiny little motor, which spun so fast. They had considerably more airflow and a much larger bag capacity than the original Constellations. The hoses were a tad short on the BOL Models, and do go into the cleaner at a pretty low point -- but they weren't bad machines as far as cheap bottom of the line machines go.
