Every time I mop the floor, so I guess that would be 2-3 times a week. I have a drawer under the stove that pulls out and the fridge is on rollers and the stove is electric so its really not a big deal to move things around. My mother, on the other hand, just dug a cat toy out from under her stove last weekend and her cat died 7 years ago!! Hehehe just tattled!
