The Blue Devil King Fin B3516KFBU is a dual-action power brush engineered to deliver up to 10 times the scrubbing force of a standard pool wall brush, cutting cleaning time and effort in half. The performance comes from the King Fin's patented fin design, which generates a hydrodynamic suction effect that keeps the brush head pressed firmly against pool walls and floors during both the forward and backward stroke, delivering equal scrubbing force in both directions without the user needing to apply extra downward pressure. This one-of-a-kind dual-action design makes wall brushing possible with a single hand, significantly reducing fatigue during longer cleaning sessions. White nylon bristles provide effective scrubbing power that is firm enough to dislodge algae and buildup yet gentle enough for below-ground vinyl and fiberglass pool surfaces. The B3516KFBU arrives pre-assembled and is compatible with standard pool poles, making it a notable upgrade from traditional flat pool brushes.
- Up to 10x the Scrubbing Force: The King Fin's patented fin mechanism generates a hydrodynamic suction effect that holds the brush head firmly against pool surfaces during use, delivering up to 10 times the cleaning force of a conventional wall brush with significantly less physical effort from the operator throughout the cleaning session.
- Dual-Action Forward and Backward Stroke: Unlike standard brushes that scrub effectively only on the push stroke, the King Fin delivers equal scrubbing force on both the forward and backward stroke, effectively doubling the cleaning productivity of every pass across pool walls and floors during routine maintenance work.
- One-Handed Wall Brushing: The fin's wall-hugging suction eliminates the constant downward pressure required with traditional brushes, allowing the operator to control and maneuver the brush head with a single hand, an important advantage for pool service professionals and homeowners working on larger pools or longer brushing sessions.
- White Nylon Bristles for Vinyl and Fiberglass: Durable white nylon bristles deliver strong, effective scrubbing against algae, scale, and waterline buildup while remaining gentle enough for use on below-ground vinyl liner and fiberglass pool surfaces, where stiffer steel-bristled brushes would risk causing damage to the finish.
- Pre-Assembled and Pole-Ready: The B3516KFBU arrives pre-assembled and ready to use straight out of the packaging, and the standard attachment connects directly to any common 1-1/4-inch pool pole, with no tools or additional adapters required for immediate installation and use during the next scheduled cleaning.
