Front loading or top loading washing machine?

Why do you need to clean under it?
I have no clue how to respond to this. Lol. I like things clean I suppose? Also ours is in connecting passage between bedrooms and kitchen/bath. It's an open type space which is cleaned regularly. And when you have a old open like house, you know big arse windows open almost the whole day, well, you get dust.
My machine is in the bathroom and there is nothing under there. Other than some dust which you don't get much of in a bathroom anyway.
Bathroom imo is one of the most practical places for a WM. Unfortunately I don't want to replace it as it will involve some plubming and sh!te.

Rats and other things like cockroach don't bother me that much. I mean I am obsessed with these things. So a rat enters our house (happened two days ago ironically), and it exists dead the next day. A typical hygiene obsessive here but no matter what lizards I cannot control.
