The E-Cloth Deep Clean Mop Head Variety Pack includes two mop heads and two dust heads that attach to our Deep Clean Mop to strip grease, grime, dirt, and over 99% of bacteria from all types of hard flooring. Wood, tile, or laminate, they clean and protect your investment - using just water. There's no need to add chemical cleaners - or worry about crawling kiddos and curious pets. The thick pads go to work with masses of precision-engineered microfibers, activated by water's cleaning power. Quick-grip hook-and-loop fasteners makes the mop heads easy to attach and remove. To refresh, just toss in the laundry. Because unlike single-use, throw-away refills, our reusable mop heads are made to last - and guaranteed to perform for 100 washes or 1 year. So much simpler, swifter, and savvier, it's hard not to share the news.
