Our kitchen floor is perpetually dirty. Our kitchen is at the back of the house with a door to the back "garden" and alley. We don't have an entrance hall at either end of the house (traditional Victorian terrace). We use the back door to go in and out with the pram so lots of dirt gets tracked in on the wheels plus muddy boots. We have a 9 month old so meal times are frequent and messy. I sweep food up constantly but it really seems like it needs a mop 3x a day and I barely manage once a week.
It's never seemed clean since we moved in 18 months ago and it drives me crazy. DS1 will be on the move soon and I'd like it to be cleaner if he's crawling all over it.
I used to have a steam mop but didn't really rate it.... maybe if they came in cordless???
