I had a Shark steam mop with the pads for years.  It finally quit on me.  I am so happy with this upgrade.  I cracked a rib just after I received it but just couldn't wait to try it.  I only finished one room but was so happy that it really propelled itself.  It was super easy to use and the dirt and grime that was picked up was amazing.  I can't wait to use it on the whole house
