If you've got stone surfaces that need serious cleaning, this Gloria brush attachment is exactly what you need. The robust nylon brush roller is tough enough to handle different stone surfaces without damaging them. It works with Multi-Brush speed control systems, Multi-Brush li-on models, and Power Brush speed control units - super versatile if you already have one of these systems. At 10cm in diameter, it gives you good coverage and cleaning power for tiles, natural stone, grout lines, and other hard surfaces. The nylon bristles are aggressive enough to remove stuck-on dirt and grime but won't scratch or damage properly sealed stone surfaces. It's perfect for deep cleaning bathroom tiles, kitchen backsplashes, patio stones, or any area where regular cleaning doesn't cut it. If you're tired of scrubbing by hand or your current brushes just aren't getting the job done, this attachment turns your Multi-Brush system into a powerful stone cleaning machine. The build quality is solid - this isn't some flimsy accessory that'll fall apart after a few uses. Whether you're a cleaning professional or just someone who likes their stone surfaces properly clean, this brush delivers the cleaning power you need without the elbow grease. Your stone surfaces will thank you!
