This complete kit gives you everything you need to clean your hardwood floors the right way. Includes 2 machine-washable Microfibre covers, is extra thick, durable and absorbent. Swivel design and low-profile head for those hard-to-reach areas. Cleans faster than a sponge or string mop, with no wringing and no bucket required. Better for your floors because of the small amount of liquid used. Too much liquid will cause damage to your hardwood floors. Use it with the 32 oz. WOODWISE Ready-to-Use Spray Cleaner which is included, and the job is all but done. When the mop cover becomes dirty, simply change the cover or rinse it out. Cleans all surface-coated floors except wax-based finishes. Even with proper maintenance, eventually your floor may become dull or worn looking. Contact a qualified hardwood flooring professional—it may be time for a top coat or refinishing.
