This 20 inch microfiber pad is built for the Unger Excella floor cleaning system. The microfiber surface lifts and traps dirt, dust, and debris for a streak-free result on hardwood, tile, and linoleum. It can be used wet or dry, and its durable construction holds up to repeated use so it needs replacing less often than lower-grade pads. The larger 20 inch size covers more floor per pass, helping crews clean bigger areas faster.
