Well it looks gorgeous and they're top rated in cleaning
Brush roll and edge groomers wouldn't be bad price wise. Would be cool to find an older Genuine Hoover manufactured brush roll over the newer CWP ones.
I wouldn't worry much about rug guards being broken on the baseplate as long as the main plate is in good shape and not cracked.
I've never worked on a Windtunnel Self Propelled but I'm wondering if the release could be fixed by replacing the handle release pedal? Chance are plastic is wearing somewhere and it's not catching right.
I researched part numbers on Hesco Inc. Then I got prices from Discountcleaningproducts.com, a trusted vendor that I've used a lot:
--- Agitator: 48414069: $11.84
--- Edge Groomer known to Hoover schematic as Litter Picker:
39511004: $2.20 for one x2= $4.40
--- Cord 46383331: $14.41
--- Handle Release Pedal: 38434023 (models post 2001): $1.80
Total: $32.45 + shipping guestimate $6 = approx. $38.45
In my opinion that's not bad for an excellent performing cleaner like a Windtunnel Self Propelled in such a gorgeous shade of blue too! Hopefully the self Propelled actuator arm works properly and hasn't been affected by the handle release issue.
The tool door is what looks like part number: 37257250 which is no longer available I didn't search eBay for it. I can't verify it fully either without your exact Hoovers model number. I posted a link to one on Amazon that claims it's used. There is a vacuum shop in upstate NY that would have it used/ maybe new.
I guess it's your call based on the information you received so far!!
Keep us posted on what we else we can do for you!!
