Keelcrab ONE 2023 is the first of the new generation of underwater robots entirely designed and manufactured in Italy (100% made in italy) to carry out robotic inspection and maintenance activities on the boat’s living structure by suctioning and removing the first layers of vegetation thanks also to its fixed horizontal brush.

Suggested for pleasure boats up to 45 feet, Keelcrab One-2023 vacuum&inspection R.O.V. is the entry-level robot of the keelcrab range that allows you to become familiar but in the same time without precluding the possibility of a series of consequent up-selling optionals and technical accessories as it’s born with entirely technically predispositions from factory for self-installation.

Therobot’s movement is ensured by natural rubber or P.V.A. brushes driven by tracks that allow easy manoeuvring in all directions, on any surface and making the drone adept at overcoming obstacles. The high-resolution underwater camera allows the robot to be manoeuvred by means of a wired remote control, displaying the video stream on a 7-inch display, tablet or phone (optional) in high resolution.

In terms of cleaning capability, the robot is equipped with nylon insulated counter-rotating central brushes (of variable length and diameter) that are easily interchangeable according to abrasion requirements. These A.N.C.P. certified brushes, with proper set-up i.e. following the instructions in our instruction manuals, do not remove antifouling paints but rather extend their effect over time.
Numerous tests have shown that the constant removal of the first layer of vegetation (3/5 mm) causes a drastic extension of the life of the antifouling (which returns to direct contact with the water), which translates into the impossibility of the formation of “dog teeth” (barnacles) in the medium term, reduced fuel consumption (and related emissions) and maintenance of top sailing performance (thanks to less friction of the hull on the water).
The robot  is also equipped with a keelcrab bag filtering system (optional) with a nylon filter bag with variable micrometry for the recovery of waste material, algae or vegetation, resulting from the cleaning operation.


The product warranty certificate is valid for 24 months (excluding consumables) or 500 hours of use.

Frequently asked questions

The keelcrab drone is designed to have a cleaning capability classifiable as a”routine maintenance” of your hull respecting the surfaces, chemicals and technical elements on the living work. Since there is no scale (benchmark) with regard to the ability to abrade and remove dirt that has taken root to a boat hull, we start with the mechanical concept that the drone exerts 3.5 kg of thrust (when fully submerged) toward the hull surface and moves in counter-rotation (counter-rotation effect) a cylindrical inset brush body made of nylon (of 2 different weights) or corrugated stainless steel. Micrometric tests (pre and post robot passage) in a simulated environment (including with wastewater analysis) and practical feedback led us to obtain certification from A.N.C.C.P and to demonstrate that: complying with the starting condition of “perfectly clean boat” and “painted” with new antifouling, a hull is “still on target” (still workable i.e., cleanable by the keelcrab drone) even after a period of 6 to 8 months of complete stationing in port waters.

In the case of paints that are even partially water-soluble (self-sanding) if navigation was not possible, in order to avoid micrometer reduction of antifouling when using the drone, use is constrained to the removal of the central brush body, leaving the dual tasks of keeping the machine in adherence and sucking up silt algae or vegetation to the suction capacity alone. The proportion between suction capacity in kg and robot feed rate, demonstrates how using keelcrab without its brush body simulates slow sailing (less than 3 knots) by stimulating the paint’s natural chemical self-cleaning process.

All consumable and non-consumable items (thus covered or not covered by warranty) are designed with the logic of “do by yourself” allowing maximum freedom and autonomy over drone assistance. Assembly and disassembly operations of individual marinized components are therefore executable by anyone and without the use of special technical equipment. In all cases, replacement or intervention operations are supported by dedicated video tutorials and you will be able to find them: in the restricted area of our website, by sending a w.up to +39 327 029 5197 with a request to open a service ticket or a specific request for the consumable component you intend to replace or by sending an email to ufficiotecnico@keelcrab.com with the subject line “video tutorial for technical assistance” specifying the consumable technical component you intend to replace. One of our assigned technicians will follow up with you for quick troubleshooting.

The entire Keelcrab line is entirely designed and manufactured in Italy (100% made in italy) in our production facility in the province of Como, and the average delivery time is about 2 weeks from order.

  • 12-meter boat: 1 hour
  • 16-meter boat: 1 hour and 30 minutes
  • 18-meter boat: 2 hours
All consumables are:
  • Replaceable in total autonomy
  • Available h48 directly from us
  • Durations vary from a minimum of 50 hours to a maximum of 500 hours of use.
There are no other variable costs of maintaining your device in efficiency over the years.

Abundant rinsing with fresh water after each use and sheltering in a dry, sheltered place.

Keelcrab is maintained in perfect adherence to the hull thanks to a major suction effect generated by a powerful marinized pump motor by removing and sucking up algae or vegetation that typically builds up on the live work of boats during periods of dwellings in closed waters. The keelcrab drone is capable of cleaning (once quickly mastered in piloting operations) up to the95/97% of the surface area of a displacement hull of a sailboat that exhibits characteristics of shapes and geometries classifiable as “standard” in the 10/24 meter range and 85/87% of a planing or semi-planing hull of a motorboat that exhibits characteristics of shapes and geometries classifiable as “standard”In the range 10/ 24 meters.
