Anyone have a floor tile robot cleaner

[Taishan]

Hi all,
We have recently had all our downstairs floors tiles in white/grey veined tiles.
These are the very big 3 foot square ones.
Looks beautiful when clean.
Keeping it clean is a pain.
We want to buy a tile robot cleaner, the ones that carry a few liters of water, and run out and mop the floors.
No carpets downstairs, the carpet by the fire is gone now, really is just tiles .

Yes I have a Braava Jet and he’s lovely. His tank is only about 500mL at a guess but it’s enough for a large ground floor. Has a tendency to jam himself under the sofa occasionally but it’s all part of the charm.

I've got a braava jet too they are great.
