I love the new Bona Premium Spray Mop for hardwood floors.  The previous spray mop I tried to use did not work properly.  The sprayer would only work a couple of sprays and then I would have to unattach and reattach the bottle.  It became too much work to use.  The new Bona Premium model works great.  No problem with the sprayer.  The mop is light weight and glides beautifully over the floors.  The way it is attached allows it to swing around in every direction which makes it easy for corners and to get under furniture.  So much easier to use than previous spray mop.  I highly recommend this product to anyone with hardwood floors.
