Awesome to hear!
I've noticed that there seems to be a bit of confusion going around about the CMS and ClearTrak so I'll try list them first.
-The flat back of the bin and tapering did not happen on the CMS. That design was introduced when the ClearTrak came out in 1991. I believe they did that to make it easier for people to remove the bin from the vacuum. The flat back was to help the bin from hitting the cord hook area.
- For the motor, CMS and ClearTraks never came with a 7 amp. It was always an 8 amp. I don't know where the whole talk about CMS' using 7 amp motors came from.
Now for the CMS-1000. The CMS-1000 seemed to have gone through three changes between 87'-88'.
-Early CMS-1000's were labeled as the 'CMS-1000A'. I've seen multiple CMS' including yours which had the 1000A name printed on the bottom label.
-There are two different versions of the 1000A. The early version (what you own) had the ring around the cyclone, a light grey colored power cord similar to the ClearTrak, a grey brush roll, the filter tray did not include a filter frame (which goes between the foam and sub-micron) and it used a circular reset button.
-I believe the later version was sort of the transition into the final version, or the 'CMS-1000'. The ring was removed, the power cord was changed to a dark grey color and the reset switch was changed to a smaller square one. It still used the same grey brush roll.
-Then we move on to the CMS-1000 (my machine), basically the same as the later 1000A but the grey brush roll was replaced with a black one and a filter frame was added.
So I think I have a rough date estimate for the 3 different changes.
-1987 to Early 88' (Early CMS-1000A version)
-Early 88' to Mid 88' (Later CMS-1000A version)
-Mid 88' to 1990 (Finalized CMS-1000 version)
The six photos down below are of the early/later CMS-1000A vacuums and the final CMS-1000. First two being early and middle two being late and last two being final.
