I probably average once a week for all rooms.
We have 3 dogs and although we live on a quiet cul de sac there is a busy road and farms behind us. Causes quite a dusty house.
I also wipe doors down (white gloss) weekly.
We bought our house as a do-er upper (bought thinking it was unliveable and had to be done immediately) but then life got in the way. The grubbiness was awful so now the house is fully redecorated I am a little OTT.
I feel like people do it less than me cause we’re inherently messy qbut not sure.
