Our Microfiber Mop Recharging Buckets are constructed for wetting Microfiber Mop Pads prior to use. These buckets are standard size and will fit on most maid carts. They will hold up to 6 gallons of cleaning solution or approximately 20 cleaning pads depending on the type of pad being treated. Lids seal tightly and these buckets are available in Gray or Red colors for color coding systems.
