7S

Totally fine!  7S was the first for me 2 years ago and it made my life so much better. It's the best purchase I've done in my book.  Make sure to check where you can buy spare parts, new filters, etc. You'll need some in a while! 

Ja od kilku lat mam Robrocka S7 i mogę polecić. Wcześniej miałem Xiaomi, ale zmieniłem na Robrocka bo mop jednak robi robotę.

My tile is a thousand times worse than yours, and it misses some spots. I get it to do 2x where it changes directions between mops. I have an s7 mop, I feel like the circular mops might be better for odd surfaces like this. Manual mopping would always be better, but I just don’t want to spend that much time mopping. I got better things to do.

I have Roborock S7/S8, it's very reliable and worth the price. I've had it for 4 years now. Just need to keep the sensors clean and filters monthly.
