I use this Crosswave steamer to clean tile and engineered wood. I vacuum an area, then depress the steam button to go over it again with the "steam mop" feature. The max fill clean water tank cleaned 750sq ft as it advertises...but I did have to stop and empty the dirty water tank halfway through, and add more clean water and solution. So there is no, clean 325sqft or 750sq ft.... It does 300sqft at a time. There are no written or picture instructions in the box... but I found plenty of videos online for review. You still should drymop at least to pick up spills on the floor. This mop is not height adjustable. And it will not act like a wetvac and pick up, say, spilled food. You do need to move slowly to clean floors. However, still faster and easier than sweeping, vacuuming and THEN mopping!
