Sublue (深之蓝), a domestic manufacturer of remote operated vehicle (ROV), today launched its first-ever swimming pool robotic cleaner BlueNexus.
The Tianjin-based firm introduced BlueNexus, which it said is a cordless swimming pool robot, a huge departure from most peers in the market.
BlueNexus, which is equipped with all-in-one ultrasonic and infrared laser ranging sensors, can move around in an underwater environment on the back of its self-developed WSLAM (water simultaneous localization and mapping) algorithms.
As the underwater drone-like device navigates the pool along a zigzag path, it maps the surroundings in real time before it plans an optimal cleaning route.
Minimal risk of collision
The sensors can project sonar signals 20 times per second and identify objects as far as 20m away, with a level of precision down to millimeter.
BlueNexus comes with 12 sensors of seven types. With multi-sensor coordination, it detects pool walls, steps and other obstacles, minimizing the risk of collision and causing damage to the pool and itself.

“Our robot is able to clean 98% of a 25-sqm pool’s surface, compared to a coverage of up to 93% for its top-tier competitors’ in a pool of the same size,” said Wei Jiancang, founder and CEO of Sublue.
Besides, it takes 20 minutes for BlueNexus to clean a pool this large, about two-thirds less than its rivals, he added.
With an all-wheel drive system, the device can defy gravity and scale walls, removing dirt sticking to usually hard-to-reach corners and edges.
Controlled via a mobile app, BlueNexus is deployed with the press of a few buttons. Users can add more features to it with OTA updates.
Its built-in 28,500 mA/h lithium-ion battery is able to keep the robot running for 210 minutes. A single charge, which lasts three hours and a half, can power the device for a week.
A global race to the bottom … of the pool
Sublue said this gadget has hit the US crowd-funding site Kickstarter for pre-order.
Worldwide, the United States has the largest number of swimming pools, estimated at 10 million. Nearly one in 31 Americans owns a pool, compared to one out of 21 in France and one out of 10 in Australia.
In 2021, global pool cleaning robots reached a market size of 10 billion yuan, with a penetration of only 19%, said Wei, the CEO, citing unspecified sources.
With its entry into the pool cleaner segment, Sublue will find itself up against opponents like Winny Pool Cleaner (望圆科技), Aiper (元鼎智能), Degrii (众清科技) and others.
