Found this online..........Bamboo floors, like other wood floors, are averse to excessive water and moisture. You should bear this in mind when cleaning such a floor. For daily cleaning use either a dry flat microfiber mop or a dry dust mop. If you must use a vacuum cleaner you will need the attachment to be soft at the bottom so that the floor is not scratched. Notice that these techniques have omitted the use of water.
In the event that foods or liquids have been spilled, clean the floor using a slightly dampened soft cloth. Bamboo flooring shouldn’t be cleaned with any polishes, waxes, oil soaps or solvent cleaners, despite the amount of dirt. There are floor cleaners designated especially for bamboo floors that you can buy
