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

- Pack size: 1 pair (2 blocks)
