3-TANK SEPARATION SYSTEM: PURE WATER FOR PURE FLOORS--We've all faced that grim moment: watching your mop water dirtier than your floor. That's not cleaning it's just moving dirt from one spot to another. Our mop bucket with wringer changes everything with separate chambers for clean water, dirty water, and the washing zone. This means every time you rinse, you're using truly clean water. 2000MAH AUTO PUMP: ENDLESS FLOW, PERFECT SOAK -- Say goodbye to the feeble trickle of manual pumps, which leave your mop half-dry. Our flat mop and bucket system doesn't just wet your floor mop; it drenches your mop in a uniform deluge that reaches every fiber.
