The Shark® Slim Professional Steam Pocket® mop has intelligent steam control™ which produces a continuous flow of steam. The Shark® Professional Slim Pocket™ Mop uses electronic variable steam control™ to offer separate heat settings for light or heavy-duty scrubbing. Steam is created electronically, so there’s no pumping, and the flow of steam is kept consistent, allowing for easier, more even cleaning. The double-sided steam pocket produces steam on both sides of the head, circulating steam better so your floors dry almost instantly. And you can clean twice the floor area – just flip over the head.
