Whistle Mop is the self-cleaning mop system that rinses and refreshes itself as you go, so you always mop with clean water and a clean mop. The secret is the Dual Tank System that keeps clean and dirty water separate, while the Self-Cleaning Bucket rinses and removes hair and debris, so the mop comes out clean as a whistle. Simply lock the mop into the bucket and pump the handle to activate the spin-clean action, then spin dry to remove excess water. The dual-edged mop head hugs baseboards for a complete clean, and the reusable Microfibre Pad cleans all kinds of hard surfaces and messes.
