I was with my girls looking for a Christmas present for Mom. My 6 yr old walked around the corner of the aisle we were in and started screaming for me...
"DAAAAAADDDD!!!!!! We HAVE to get this for Mom, it's the BEST!!!!"
It was a Shark steam mop. Turns out, she was addicted to the infomercial and watched it all the time, LOL.
So, we bought a Shark steam mop.
Go back a few months and we had an area rug in the middle of the hardwood floor in the living room. My wife had used double sided carpet tape a long time ago. She bought a new rug and it was smaller than the old one, so she pulled up the old rug and tape and adhesive residue was stuck all over the floor. Nothing we tried would get the residue off the hardwood. We tried everything from many floor and kitchen cleaners to GooGone and even WD40. Nothing would take it off.
Now fast forward back to Christmas. The steam mop was opened and I handed it to my 6 year old daughter and said, "It was your idea to buy this, you get to try it first."
She rubbed it around where the adhesive was stuck to the floor and everything came up with such ease. She got rid of all the adhesive no problem.
As others have said, the floors never felt so clean. We bought one for my mother for her birthday. She used a swiffer all the time, so she tested the steam mop. She used her swiffer to clean the kitchen floor just like she always does (she has major OCD on cleaning, so she really cleans when she does.) After the swiffer and the floor dried, she tried out the steam mop. The cloth of the steam mop was filthy after using it directly after the swiffer.
Yes they really work and really clean the floors.
