Robotic grooming is a proactive maintenance service designed to prevent heavy growth. If your boat has been sitting for a year and has significant "hard growth" (barnacles), we recommend an initial haul-out to reset the hull. Once clean, Hull Guardian keeps it that way permanently.

No. Our robot is specifically engineered for the high-precision grooming of large hull surfaces. Due to the intricate geometry of propellers, shafts, and water intakes, these areas cannot be safely cleaned by the robot. However, we use our high-definition 4K cameras to perform a detailed visual inspection of these components during every session.

Our robot uses a high-powered vacuum suction system (A.V.S.). This creates a physical bond with the hull without the need for magnets, which can interfere with onboard electronics or compasses. It is safe for all hull materials, including GRP, Aluminum, Steel, and Carbon Fiber.

We use specialized neutral-buoyancy soft nylon brushes. These are specifically designed to "groom" the slime layer off the hull without applying excessive pressure. Because the brushes are counter-rotating and balanced, they remove the fouling while leaving your expensive antifoul coating perfectly intact.

Yes. Because we use soft-touch brushes and vacuum suction rather than aggressive scrubbing, our system is ideal for high-performance racing hulls and vinyl-wrapped vessels that require a much gentler touch than a scraper.

Every Hull Guardian service includes a 4K LED Diagnostic Report. Our robot is equipped with high-definition underwater cameras and powerful LED lighting. We provide you with a digital video of your hull, propellers, and anodes after every clean, giving you a "below the waterline" view of your vessel's health.

Every vessel is different, however, most grooms can be completed in 90 minutes. Because we are a robotic service, we are significantly faster than manual cleaning.

The robot is fitted with a 50-micron nylon filter. As the brushes lift the fouling, the vacuum system pulls that material into the filter bags. This captures the foul before it can be released back into the marina.

Traditional cleaning releases biocide-heavy paint dust and biological debris into the water column. By using a vacuum-capture system, we significantly reduce the environmental impact, keeping our marinas cleaner and our ecosystems healthier.

Hull grooming is about prevention. If a hull goes too long without grooming, "hard growth" (like barnacles or tubeworms) can begin to form. Our robot is designed for "Level 1 & 2" fouling (slime and grass). If hard growth occurs, a manual reset (haul-out or diver) may be required before we can resume your high-performance subscription.

Yes. As part of our 4K video report, we do a visual sweep of your anodes, intakes and prop. If they are looking low, we’ll alert you in your report so you can action these accordingly.
