Ive heard many Rainbow experts, salesman, owners, and repair techs say that the D2 "Chrome Dome" (74-79) was/is the best of all, easiest to use, and easiest to repair. Seems like a repair tech told me once that the D2 has more fans/turbines than the others, so therefore more air flow? Im assuming as long as they are in A1 condition, and perfectly clean seperator, this is true.
I would think that with a new Vibra Groomer brush roll, new belt, fans and "spider" in A1 condition, clean hoses and clean seperator, a D2 is still an excellent vacuum cleaner.
Just dont use it to vacuum up fireplace ash, talcum powder, or any substance that is impervious to the wetting action of water. It will all go right out the exhaust of the Rainbow.
A neighbor of mine has a D2 that she bought new in around 1977-78 from a DTD salesman, and is still going strong.
She said she has had motor repair and cleaned out a few times over the yrs, new hose, did replace the water pan once, brush roll and belt on the PN, and always cleans her seperator with a tooth brush after every few uses,,but other than that, her D2 is still going strong to this day.
She says the secret is to NOT clean too long with any one filling of water.
She says she stops every 20 min or so of use and dumps and refills the water pan,even if the water is NOT that dirty,,and always has. So, evidently if you take care of a Rainbow, and know how to use it correctly, it will last!,,at least a D2 sure will.
