Here's the thing about mopping - it pushes dirt around. Some of it settles back into the grout lines, and over time that buildup gets darker and harder to ignore. Regular cleaning keeps the surface looking okay, but it doesn't get to what's actually stuck in there.
We were out in Sunnyvale working on a kitchen tile floor that had hit that point. The tile itself is a nice travertine-look ceramic, light in color, which means any discoloration in the grout stands out pretty clearly. Good-looking floor with grout that just wasn't keeping up.
We use a rotary tile cleaning tool that works with hot water extraction. The spinning head scrubs the surface and grout lines at the same time, and the extraction pulls the dirty water back out instead of leaving it to dry back into the floor. It's a completely different process than mopping, and you can see the difference in the result.
The floor came out noticeably brighter and the grout lines cleaned up well. That's the thing with professional tile and grout cleaning - it's not just about aesthetics. Grout is porous, and when it stays grimy, it holds onto bacteria and buildup that regular mopping won't touch. Getting a deep clean done periodically keeps the floor in better shape over the long run.
If your tile floors have started looking dull or your grout lines have gone dark, it's probably not the tile itself. It's just buildup that needs the right equipment to pull out.
