Let me say I usually do the cleaning of floors. We have a moderate sized 3 bed semi which has ceramic tiled floors throughout the downstairs and two dogs!
I Hoover and sweep the floors every day and will spot clean. Or use a floor wipe where the dc have split a drink etc. Then 3/4 times a week I will mop as well.
I use one bucket of water with cleaner for the hallway and lounge, another for the dining room and study and another for the kitchen and utility.
Dh has the day off today and so while I took the dc to school he made a start on the floors. I came home and he was just finishing the dining room and about to start the kitchen. He didn't change the water. I asked as casually as I could when he changed the water and he said he didn't need to one bucket was enough for the downstairs and he'd change it to do the bathroom and loos upstairs
I'm now at work thinking I need to do the floors again when I get in as kitchen at the very least won't be very clean. It's been wet and muddy here so the water won't have been very clean for the kitchen floor.
