It lives!
Success! Thank you vacman1961 for suggesting the Princess 48, that got me further. I found a replacement brushroll on Amazon for $50, I wasn’t finding much luck elsewhere. But today I found one for $20 on CompleteVAC, so whatever. At least the one I ordered fits and works, that’s what matters.
And thank you tylerhawkins84, I’ll definitely try that on the replaced brushroll, I know it has more life left. I’ll keep it as a backup for one of my other Royal power nozzles. Maybe I can replace the end caps, I see those all over the place. Especially since I lost one of the washers on disassembly!
Now it’s almost complete, the last piece I need is the bumper for the power nozzle. I’m looking up bumpers for the Princess 48, but that seems to be scarce as well. Anyone have any tips on where to source a bumper that would fit?
