Hull cleaning can be fun, easy, and just as important as above the waterline! Keel Crab is a remote, human controlled underwater brush that sticks with vacuum suction to boat hulls (and swimming pools) to gently sweep and remove algae and loose vegetation. It is ideal for regular cleaning of a boat, avoiding the need for lifting the boat, and also reduces the need for heavy scraping of the hull. Regular use of Keel Crab will extend the effect of any anti-fouling paints also!
Typically a hull might take 1-hour to clean with the Keel Crab and so the machine is a great purchase for a group of boat owners, marina to lease out, and club.
A full range of spares is available, service and support to ensure your investment serves you for many years.

Upgrades on the 2020 version
Speed and Power
- Better performance: engine enhanced with 500 extra revolutions and water flow rate increased to up to 50 square metres per hour.
- Greater cleaning efficiency: the counter-rotation speed of the central brush is faster than the drone’s forward speed.
- Drone’s forward speed: 1 meter in 3.5 seconds.
- Cleaning capacity: 1 meter in 12 seconds.
Ease of maintenance
- All the fabulous features and capabilities of the previous version plus improved camera adjustment, brush exchange, cleaning process and waterline.
- The drone can be disassembled in all its components in order to facilitate the best safety and efficiency in routine maintenance operations for cleaning the propellers, replacing the brushes, wall-grips or natural rubbers, and also the engine in case of need.
About the Company
In 2009, Aeffe s.r.l. obtained the first European patent for a robotic device for cleaning boat hulls. Since then they have won awards, certifications, and investment support. Keelcrab is therefore in fact much more than a product, it is a worldwide network created by revolutionaries who have built their lives around their passion for the sea and for navigation, making it a job.
Aeffe s.r.l. stems from a strong business spirit and passion for underwater robotic technology. Its beating heart is its team, which boasts technicians highly skilled in a wide range of fields: from electronics to mechanical design, from computer science to underwater technology. Having reached technical and commercial success with the KeelCrab underwater drones (European patent), today the company finds its core competency in underwater mecha-tronics.
Highly specialised in cutting-edge design and construction techniques, our strength lies in constant technologic and eco-friendly research and development, understanding of markets, products tailored to the needs of our customers, customer feedback in the product improvement process, and speed.
Underwater mechatronics: our real value
Our mission is providing eco-friendly, efficient and cost-effective solutions, in order to solve the maintenance and fouling problems for hull boat, pool and aquarium tank. We promote a worldwide network of professional services that use our technology and help us spreading a new paradigm in nautical and underwater maintenance.
Over time we have implemented and promoted solutions capable of reducing costs of time and resources not only for boat maintenance but also for in-ground pools and aquariums. Today the Aeffe s.r.l. philosophy is to open up to the development and consolidation of a network made of professionals in the marine and underwater sector who, through their activity based on the KeelCrab technology.
