Some good mops for hardwood floors are the Libman Wonder Mop, Bona Motion Mop, Bona Curve Hardwood Floor Mop and the 18-inch Household Swivel Mop, which are all made of microfiber.
Microfiber mops are generally more preferred for hardwood floors because they require
less liquid and cleaning solution, which reduces the chances of ruining the wood.
The Bona Motion Mop comes equipped with a refillable cleaning solution container and a sonic motion feature that rapidly vibrates the head of the mop to increase its cleaning power. The sonic motion is controlled by a button on the head of the mop so that it can only be used when needed. The mop is powered by four AA batteries.
