Hi Venson,
I recently saw this through CR, very interesting. I'm thinking that the turbine (which as we know all dirt/debris goes through) is what is flying apart and possibly going through the plastic housing. We all know how fast those things turn, especially such a small nozzle like this one, and I certainly wouldn't want to be around if it decides to self-destruct during use!
Yet another side effect of inexpensive manufacturing, and the use of cheap plastics with questionable durability. Probably the reason turbo nozzles have become more common on low-priced cleaners. The only turbo nozzles I would use at this point would be the VacuFlo-made versions (both the large TurboCat and small RugRat), the Dyson turbine heads, and the Hoover TurboPower nozzle that is used on the Constellation. Certainly not anything included with a cheap Hoover, Dirt Devil, or Eureka. Even before this I had heard about the cheap turbo nozzles included with those cleaners breaking all the time.
Incidentally, one of the Dirt Devil vacuums that uses this particular tool is the Spinnergy. The turbo nozzle is mounted right on the front of the cleaner.
