Brush Strip Set — replacement brush strips engineered for reliable, targeted cleaning. Reliable bristle design: dense, resilient bristles hold up to regular use and maintain consistent scrubbing performance so you can depend on them job after job. Penetrates grout and tight joints: bristles are shaped to reach deep into grout lines and narrow gaps, lifting embedded dirt and stains without excessive force. Extranarrow, elongated profile: the slim, long strip increases reach and coverage in confined areas, letting you clean faster and with better contact on narrow surfaces. Easy to swap out: strips install and remove quickly so your cleaning tool stays effective — worn strips in seconds instead of replacing the whole tool.
