This item was purchased for use with Shark Steam mop. Excellent fit! Made for unit. Nice thing I learned is you are able to use both sides of the head without touching the pad while cleaning. You actually have 2 pads in 1. The steam unit is manufactured in such a way that you need only "flip" the head & the clean mop side flips down to allow continued cleaning. You need not worry about change until your mopping is completed, The second nice thing is these pads are completely reusable. Just wash them & you are good to go. The pads are very soft & absorbent. No need to worry about scratching quality wood floors or tile. Vinyl comes up shining beautifully. Used on my vinyl mudroom flooring & needed to area spray (w/cleaner) at 1 small spot. Remainder of the mopping was handled with the steam only. Parcal (wood tiles) flooring was beautiful after mop was used on area. That particular area had cat litter powder coating the floor & no matter what type of mop I used it only streaked. The softness of these mop pads almost buffed the wood while absorbing the powder & normal "walking" dirt, etc. If you purchase a Shark steam cleaner w/ the square type head these mop pads are what you want. I would suggest buying a box (contains 2 double sided) mops at the same time. Soft, thick, absorbent, you cannot get much better than that. Except for the perfect fit. I've never purchased a mop that did not give me problems when attempting to purchase new mop pads that would fit correctly. Strongly recommended. Buy the steamer--don't forget a box of these mop pads!
