Uses rotating blades to pick up large particles and flicks them into a dirt bin. At the same time, the attached Swiffer Sweeper dry cloth traps dirt, dust and hair that brooms can leave behind. This innovative combination cleans up big and small messes in a single swipe. Uses the same dry cloths as the Swiffer Sweeper. It's lightweight compact and has an ergonomic handle. The rotating blades and dirt bin are easily removed for cleaning and just as easy to reattach. No batteries or power is required so it's just as quick to use as a broom, but it'll give you a much better clean. For refills refer to Model No 31821 (SKU 615891) and 31822 (SKU 615908).
