Simmonspaul0311, you are a genius. I was tired of having the brush get stuck in the middle of an open part of carpet without the brush actually being stuck.
I didn't use pliers, but rather a thin flat screwdriver to pop the parts apart. Lots of hair in there, it was crazy. I cleaned that out and now the Eufy is back to what it does best: finding new and interesting ways to get stuck.
The only problem is that the parts are now loose as they didn't have the original crimping any more and last night the Eufy was squeaking. A little white lithium grease will do, but I am afraid that will attract more hair.
This appears to be a part that needs to be routinely maintained yet was not built with maintenance in mind. I wonder if there is a redesigned part that will get around this problem. I will contact Eufy directly about that.
