We went through this at sleepy o clock and what saved my sanity was ditching that model steam for a simple water bath... I fill a mug or bowl with hot tap water or kettle water that sat for a minute, stand that model that model in it up to that model milk line, and swirl a few times. Takes about a minute for a small that model from that model fridge and a bit more for bigger ones.
If you want to keep using that model warmer, start that model cycle then stop it early and let it sit 30 seconds while you swirl. that model heat evens out without blasting it. Cheap fix.
Make it a quick routine you barely think about by rinsing the foam and felt after vacuuming, drying them overnight, and clearing hair and dust from the brush bar, intake, and wand... Sit at a table if kneeling hurts, and skip carpet powders so filters last and suction stays strong.
