Am I wrong!?

So my husband let his mom borrow the floor cleaner we have, I was the one to clean the inside of the cleaner and the filter, also clean the carpets, so I know for a fact it was clean, this was before I got pregnant, now we are going to use it again this time my husband to clean the carpet again since we have a month for the baby to be born, and I asked him to make sure to make his mom clean the machine and filter before she gives it to us since I we gave it to her clean and it’s gross to use it all dirty especially since she has cats, and my husband doesn’t want to ask her and it makes me so upset but I said fine you clean it then I’m not going to do it being this far along and it’s not my mess to clean, and he wanted to wash it in our tub and then got upset when I told him to clean it at his moms since I just cleaned the tub and also know for a fact he will just use the machine without watching it and it’s not a professional machine and it’s small so it gets dirty and gross if not cleaned, am I wrong? I mean I feel he should make his family clean it since they used it
