Sleeves or covers refer to the scrubbing agents attached to a T-Bar. The sleeve is essential for removing stubborn dirt or stains. Sleeves are made of synthetic materials or durable microfibers that can lift off dirt. Scrubbing power depends on the sleeve but can mild, hybrid or aggressive. WCR carries a wide selection of sleeves including Maykker, Ettore, Moerman, Pulex, Sörbo and Unger. Most sleeves can withstand many washings due to the durable material. The hooks or loops used to wrap around the edges of the T-Bar hold it in place. Sizes for sleeves depend on brand but range from 6 inch to 22 inch in single or two-tone colors.
