The weakness of pool robots until now has been that they "can only clean the bottom." But the Beatbot AquaSense X is different. It's equipped with the industry's first "ballast tank system," which takes air in and out as needed, surfacing and diving just like a submarine.
First, it floats to the surface and propels itself forward with a powerful propeller, sucking up floating leaves and insects in "Skimmer Mode." Once the surface is clean, it automatically dives and switches to "Cleaning Mode," scraping away the slime from the floor and walls. There's no longer any need for a human to walk around the pool with a net. Top and bottom — it's all handled by this single device.

Random navigation that only "turns after bumping into a wall" is a waste of battery and time. The AquaSense X is equipped with over 20 sensors and a quad-core CPU, accurately mapping the shape of the pool underwater.
Using optimized "N-shaped" or "S-shaped" routes, it cleans efficiently as if filling in every inch. Obstacle avoidance has also been improved, so it won't get stuck on steps or drains. The app screen displays the cleaning path in real time, making it easy to see at a glance which areas have been cleaned. It's as smart as a Roomba that's gone underwater.

It doesn't just suck up debris. The back of this robot can be loaded with a cartridge of water clarifier. While cleaning, it evenly disperses the clarifier into the water at the appropriate timing.
This causes the fine cloudiness and dirt that filters can't catch to clump together, making the water as clear as crystal. The robot takes over part of the tedious chemical management for you. It's the world's only device that handles "cleaning" and "water quality management" at the same time.

After cleaning is finished, hauling a heavy robot up from the bottom is hard labor. The AquaSense X automatically surfaces and waits at the wall's edge when cleaning is complete or its battery runs low (Surface Parking).
After that, all you need to do is gently pull it in with a hook and lift it out. No straining your back, no plunging your hands into cold water. Since it's cordless, there's zero stress from untangling cables. Just place it on the charging dock, and it's ready for its next mission.

The price is around 350,000 yen (about $2,200). It's extremely expensive, but considering the cost of hiring a pool cleaning service and the labor of working under the blazing summer sun, it's well worth the investment.
The Beatbot AquaSense X frees the "luxury" of owning a pool from the "drudgery" of maintenance. All you need to do is dive into the clean water. Leave everything else to this clever submarine.
