The NEW Shifter MAX 427 (18″) is a high-performance water-fed brush for glass and solar cleaning. Designed for commercial and residential use, it features durable polyester and nylon bristles that retain their shape even in hot water. The quad trim with four bristle lengths provides superior scrubbing, while the semi-radial lip ensures effective corner cleaning. The brush covers 50% more area than a standard 10-inch brush with less pressure, making it ideal for high pole work. Lightweight and easy to handle, with visible bristles and a Wiel-Loc socket for quick brush changes, the MAX 427 is perfect for solar panels and windows.
