The orange brush, while fitting properly into the vacuum, does not do the job. The vacuum suddenly does not suck up dirt like it used to. Also, compared to the original brush, it is clearly of inferior quality. The rest seems okay.

The orange brush that goes underneath doesn't work for the vacuum, it doesn't rotate freely because it doesn't attach correctly, it presents a resistance compared to the original, resulting in damaging the socket... a vacuum is going to be thrown away...
