The AIPER Scuba V3 is a revolutionary cordless robotic pool cleaner that leverages artificial intelligence to transform pool maintenance. It is designed for homeowners who want a truly hands-off experience, from scheduling to retrieval. The robot uses a single front-facing AI camera to detect over 20 types of debris and navigate directly to them, cleaning up to 10 times faster than traditional pool cleaners.
Standout features include the Cognitive AI Navium Mode, which creates autonomous weekly cleaning plans based on pool size, weather, and cleaning history. Once activated, the robot runs without any user intervention, keeping your pool consistently clean and swim-ready. The automatic return to the waterline after cleaning, coupled with real-time app notifications, eliminates the need to enter the pool or use tools for retrieval.
Design and build quality are impressive. The Scuba V3 weighs only 8.2 kilograms, making it easy to lift and transport. The wireless charging dock requires no installation and safely charges the robot without plugs or drying. The MicroMesh Multi Layer Filtration System captures both large debris (180 micron) and ultra fine particles (3 micron), ensuring crystal clear water. Additionally, the device is TUV certified for data privacy, processing all visual information on the device without storage or uploads.
Drawbacks include a higher price point that may not suit all budgets. The reliance on the AI and app means that connectivity issues could disrupt the automated scheduling.

Buying Guide
Pool Size Compatibility and Navigation
Large pools demand cleaners that can cover length and width efficiently. The Dolphin Nautilus CC Plus is rated for pools up to 40 feet in length, using smart navigation to avoid missing spots. The AIPER Scuba V3 relies on its AI Patrol system with a front facing camera that identifies debris and navigates directly to it. Both handle rectangles, L shapes, and freeforms well. Check your pool dimensions to see which design matches your layout best.
For more details on pool size requirements, see our large pool cleaners category page.
Cleaning Power and Surface Versatility
Wall climbing, scrubbing, and fine debris filtration set apart serious cleaners. The Dolphin model features an active scrubbing brush that climbs walls and scrubs tile lines gently but firmly. Its top load filter basket catches debris and is easy to empty. The AIPER Scuba V3 uses a MicroMesh multi layer filtration system with a 180 micron layer plus an ultra fine 3 micron layer that traps sand and invisible contaminants. It also climbs walls and cleans the waterline effectively. If you have plaster, fiberglass, or vinyl, both are safe choices.
Ease of Use and Maintenance
No one wants a complicated setup. The Dolphin Nautilus CC Plus offers plug and play simplicity: just plug in, drop in the pool, and power on. It cleans for two hours then shuts off. The AIPER Scuba V3 takes cordless freedom further with a wireless charging dock and automatic return to the waterline after cleaning. You get app notifications when it is done. Both require minimal manual intervention, but the AIPER’s cordless design may appeal more if you dislike managing a cable.
