Keep your BN PRO planted in saltwater. This snap‑on counterweight offsets the extra buoyancy saltwater adds, so the robot maintains solid floor/wall contact and lets GeoGuru™ AI map and clean with its full 3× efficiency advantage.

Why it matters

• Restores proper traction in denser saltwater, preventing the unit from “floating” and losing brush/suction effectiveness.
• Preserves precise GeoGuru™ routing (S‑path planning) for complete, no‑redo coverage.
• Fast, tool‑free attach/detach for seasonal or mixed‑water use.
• Low‑profile design—doesn’t block filter access or charging.
• Designed exclusively for the SUBLUE BN PRO.

Install in 3 steps

1. Power off and dry the BN PRO.
2. Align the block with the designated mount and snap it in place.
3. Do a quick float test; add/remove blocks if needed for steady floor contact.
