shark steam mop- not impressed, other suggestions?

[abseptember17]

We have about 1500 sq feet of terra cotta tile in our house.  It is not level/smooth and has wide grout lines.  I tried the shark steam mop.  It was ok but I think it looked just as good when I used the Swiffer wet mop.  I've never used a steam mop before so I'm not sure what's normal but the tile really wasn't wet at all.  Is that how steam mops are supposed to work?  Any other suggestions for cleaning this tile?  Thanks!
