But do they really clean?
"Yes, they really do," says Carolyn Forte with the Good Housekeeping Research Institute.
"We found in our tests that they remove sticky stains. They remove oily stains. So if you are not thrilled with the regular mop and bucket and you want a little bit more thorough cleaning, we found that they really do a good job."
But, Forte says, if you use a steam mop, you've got to be careful.
"You want to make sure that you use the proper steam for the proper floor type. Too much steam could damage floors, so you don't want to do that. And again, leaving it too long in one area could cause damage. So always follow the manufacturers instructions."
Good Housekeeping's top performer, the $179 Oreck Steam-It, has a large water tank, adjustable steam and different attachments.
At $70, the Bissell Steam Mop Deluxe was the bargain pick. It works especially well on ceramic tile
