A few months ago I found one similar..model 2250 A on craigslist for $15. It's a cocoa brown color with the original beige print bag, but has the slide-type rugulator height adjuster. It belonged to the seller's mother and had sat for a while. The vibra-groomer I was filthy, dry rotted belt and just overall dirty. I fired it up and it purred like a kitten and could tell it would clean up and it did, beautifully. Up to that point, I didn't have one with that style hood and am glad to have found it. Once you get it cleaned up and service the brushroll, you'll love yours too. That motor has such a nice sound to it.
Does anyone know, did they ever make that hood style with the ESP motor?
