Sorry Luna,..not a long time bun owner, but, have been cleaning up after various critters,. oh,, at least 20, 25 yrs now 
My bun,.. lol,.. hes quite a bit different, then any other animal I have owned,.. I vacuum every other day, my house, and, that includes his x pen,..hes mostly free roam, other then night time, or, when I am away from home, so.. he has PLENTY of options, to remove himself, while I clean, but,.. he is so freaking nosey, he insists on supervising me, while I clean his area lol… the vacuum doesn’t bother him in the slightest either,.. cant even keep track of how may times I have suctioned his ears up, matter of fact
– he doesn’t flinch, a bit lol.
I used to try to give him a ” busy box cube” with treats inside, but, found out,.. he didn’t care… he wants to see what was happening to his house way more, so,.. ah well,..I just deal with him, underfoot, while I clean up his messes 
I change where his bowls are, and his hidey hut, but, wen it comes to his litterbox, no, I NEVER change that location, for, what I assume, are obvious reasons
