MCPE-177549 implies that you can brush armadillos in Bedrock Edition.
Please attach a video showing the difference in behaviours.
I have also moved this report over to MCPE as it concerns behaviour in Java that is not present in Bedrock, meaning it's a Bedrock parity issue. Please make sure the platform and affects version/s are correct.
