im going crazy help requested

@kindle77615 the motor in your image, is that the one you need or one of the ones that does not fit. Your motor number is XCR380SH21140 which shows something like this.

That would mean that he same motor was used with a different plastic "transmission" which is of course entirely possible. If you can (and if there is) post an image of the model number tag (shield) which should be on your Ecovacs casing somewhere, with your question as well.

Not sure if it is possible but take a look at your "transmission" and see if the motor could be removed and subsequently be replaced with one from those that doesn't fit right. Currently it does not look like there is a brush motor for the X8Pro available anywhere. Most likely since it is still pretty new and considered the Flagship. I wonder if Ecovacs is hanging on to those motors for now.
