Compatible with steam cleaner models SC1, SC2, SC3, SC4, and SC5. Let the attachment cool down before replacing it to avoid high steam weakening and damaging the plastic. The extended nozzle and curved nozzle enhance cleaning performance, making it easier to clean seams, corners, edges, and other hard-to-reach areas. High-strength bristles with the small round brush effectively clean greasy and dirty surfaces. Before installing the brush, ensure the nozzle is inserted into the lower bayonet and securely locked. When replacing the brush, ensure it is fully unlocked before removal to prevent damage to the plastic lock. Package includes: 2 nylon round brushes, 1 copper wire round brush, 1 black extended nozzle, 1 curved nozzle, 1 yellow nozzle, 1 copper wire cleaning brush, 1 nylon cleaning brush, and 2 black seals.
