Sweep Deep engineers mission-specific underwater systems rather than simply assembling drones. Founded by Alicia Dunn, the business combines open-source flexibility with industry-grade Blue Robotics components for invasive-species control, marine-debris recovery, and critical infrastructure inspection. Its approach centres on custom tooling—from disc cutters and grappling hooks to urchin cullers and spear guns—engineering-first hulls machined from solid 6061-T6 alloy for hydrodynamic and structural performance, and an open architecture that keeps each ROV repairable, expandable, and ready for future missions.
Our Engineering Legacy
Sweep Deep has a proven history of tackling the ocean's toughest problems. These designs are tested in the field, from debris recovery to subsea inspection and environmental remediation.
Marine Debris Collection ROV
A retrieval platform featuring twin disc cutters and deployable grappling hooks for ghost nets, tyres, and heavy marine debris.
Ship Hull Anomaly Detection
A precision-machined ROV equipped with sonar and DVL, rated to 350 metres for critical infrastructure inspection.
Environmental Remediation (Urchin/Starfish)
Specialised ROVs with custom actuators for invasive-species control in reef and kelp environments.
The T500 Design
A streamlined, high-agility platform designed for efficient operation and payload capacity in challenging water conditions.

Engineering Spotlight
“The only weak link in the equation is the human... [Our systems] allow for tools to be changed in a matter of minutes, like a tractor changing from having a post-hole borer to a rotary hoe.”
