We have lived in our house for over a year now and I have never deep cleaned our entry way.
I've never scrubbed the tiles and front door and lord knows they needed it. I really should have done that.
Because this winter has been so horrible our entry has finally gotten a makeover. The front door wasn't insulated around the frame, it wasn't set quite square and since I like lots of light we decided it was time to get a new door which spurred the mini makeover. It just needed to be freshened up.
