I've had my Koh products for awhile now and love them. The cleaning clothes are amazing, no fluff left behind they do my whole house. I always wash them separately to anything else. I love the koh mop and the mop pads, i switch them regularly throughout the house as i mop. Our tiles are not smooth but have a slight texture to them and the mop is great on them. I have also used this mop on a smooth tile and it does a great job on them. As with any mop and I've used a few, if you need to clean the grout you need to do this on your hands n knees with the grout brush, not the one attached to the mop though. I also wash the mop pads separately. There is no excess water on the floor after I've mopped as there is with the bucket and old mop head style. Compared to several bucket fills in the old style mops i usually only use 1.5 fills of the water bottle. I have had to replace the bottle whuch only cost $10. Love their grout cleaner brush i have 1 in each shower.
