This replacement steam cleaning brush (small round brush) is suitable for the Krcher SC1, SC2, SC3, SC4, SC5, SC7, and CTK10 steam cleaners. It fits perfectly into the interface, is easy to install, and can be easily replaced without tools for more efficient cleaning. The brush is designed with firm, high-density bristles to powerfully remove stubborn stains. It is particularly suitable for cleaning narrow spaces such as tile grout, faucets, oven doors, and hard-to-reach corners of stovetops. Thanks to the high temperature and pressure of the steam cleaner, it easily dissolves oil, limescale, and dust deposits, improving cleaning results and saving time and effort. The brush head material is durable and heat-resistant. Even with prolonged use, the cleaning efficiency is maintained. Whether it's grease in the kitchen, limescale in the bathroom, or dust on household items, this small round brush provides a deep clean and leaves the surface looking like new. It's recommended to replace the brush head regularly for optimal cleaning results, making your household chores easier and more thorough! The set includes four colors that can be differentiated based on the usage environment (such as kitchen, bathroom, and bedroom). Each color contains two brushes, for a total of eight brushes.
