SUBLUE BN Pro Cordless Robotic Pool Cleaner

The SUBLUE BN Pro brings intelligent navigation and cordless convenience together in a premium robotic pool-cleaning system.

Before cleaning, its GeoGuru™ AI navigation system uses multiple sensors, including ultrasonic detection and infrared laser sensing, to map the pool and develop a planned cleaning route. This allows the robot to navigate complex pool shapes while reducing unnecessary repeated movement.

The BN Pro combines brushing, suction, and filtration to remove leaves, sand, hair, algae, rocks, and other debris. Its 4.5-liter top-loading filtration basket provides substantial debris capacity while making removal and emptying easier.

Key Features

GeoGuru™ AI Mapping & Navigation

The BN Pro maps the pool before beginning its cleaning route. Its GeoGuru™ navigation system combines data from seven types of sensors, ultrasonic detection, and infrared laser sensing to plan an optimized path.

SUBLUE states that this mapping-based approach can provide up to 3× the efficiency of traditional pool-cleaning robots. This is a manufacturer performance claim rather than a guaranteed result for every pool.

3-in-1 Cleaning System

The BN Pro combines three essential cleaning functions:

• Active brushing
  
• Powerful suction
  
• Dual-layer filtration
  

The dual front brushes are designed to loosen stubborn debris before the suction and filtration system captures it.

Powerful Suction

The BN Pro uses a 100W high-performance motor. SUBLUE's detailed product information lists an 18 m³/h filtration rate, equivalent to approximately 4,755 GPH, while the product's primary specification section lists 21 m³/h or 5,600 GPH.

For that reason, the two figures should be treated as separate manufacturer specifications rather than combined into a single performance claim.

Dual-Layer Filtration

The BN Pro uses a dual filtration system designed to capture larger debris as well as smaller particles.

SUBLUE states that the filtration system can capture particles as small as 70 microns. The primary product specifications identify dual 70 / 180 μm filtration.

Large 4.5-Liter Debris Basket

The 4.5-liter filtration basket provides substantial capacity for leaves, sand, hair, algae, rocks, and other pool debris.

The top-loading design makes it easier to remove the basket and dispose of collected debris without complicated disassembly.

Caterpillar Track Design

The BN Pro uses caterpillar-style tracks rather than conventional wheels. This provides increased traction and maneuverability across different pool surfaces and shapes.

SUBLUE states that the tracks can cross obstacles up to 3 cm (1.2 inches).

Floor, Wall & Waterline Cleaning

The BN Pro can clean the pool floor, walls, and waterline through its available cleaning modes.

It can also navigate slopes and common pool obstacles, helping it maintain movement across pools with more complex layouts.

Cordless Operation

The wireless design eliminates the need for a long cleaning cable. That means no cable tangles, limited cable length, or cable management during routine pool maintenance.

Smart App Control

The SUBLUE ROBOT app provides additional control and monitoring capabilities.

Depending on the selected operating mode, the app can provide:

• Remote control
  
• Real-time cleaning maps
  
• Cleaning progress
  
• Cleaning schedules
  
• Cleaning logs
  
• Notifications
  
• Water temperature information
  

The BN Pro can also be operated directly from its onboard control panel without relying on the app.

Automatic Waterline Docking

When cleaning is complete or the battery falls below 5%, the BN Pro automatically moves toward the poolside.

Its waterline docking function positions the cleaner at the waterline, making retrieval easier. SUBLUE also states that the unit can be commanded through the app to move to the waterline for retrieval.

Performance & Capability

The BN Pro is designed for residential pools up to 400 m², or approximately 4,305 square feet.

It is suitable for a variety of pool surfaces, including:

• Tile
  
• Vinyl-lined pools
  
• Fiberglass
  
• Gypsum-coated concrete
  

The robotic cleaner can operate in pools with regular or irregular shapes and is designed to navigate slopes and obstacles.

SUBLUE states that the BN Pro can collect debris including rocks up to 3 cm in diameter and 20 g in weight, as well as leaves up to 20 cm long. These are manufacturer specifications and may vary depending on pool conditions and debris type.

Cleaning Modes

The BN Pro provides five cleaning modes:

1. Smart Cleaning – Uses mapping navigation to clean the pool floor
   
2. Floor Cleaning – Cleans the pool bottom
   
3. Wall Cleaning – Cleans walls and waterline
   
4. All-Round Cleaning – Cleans floor, walls, and waterline
   
5. Remote Cleaning – Allows targeted operation through the app
   

These modes can be selected using the cleaner's control panel or through the SUBLUE ROBOT app.

Battery & Charging

The BN Pro uses a 28,600mAh / 10.95V lithium-ion battery.

SUBLUE rates the cleaner for up to 3 hours of operation in its detailed FAQ, while the current product overview specifies up to 180 minutes of runtime. Charging takes approximately 3.5 hours.

SUBLUE also states that the battery retains more than 80% of its initial capacity after 300 full charge and discharge cycles under normal use.

Saltwater Pool Compatibility

The BN Pro can be used in saltwater pools.

SUBLUE states that the robot uses rust- and corrosion-resistant plastic materials and has undergone saltwater-related testing.

For high-buoyancy environments such as pure seawater, SUBLUE specifies that an additional counterweight is required. The counterweight is an optional accessory and should not be represented as included unless your package specifically includes it.

Design & Construction

The BN Pro is designed around a cordless, track-driven platform with dual drive motors and a high-performance filtration motor.

Its design incorporates:

• Caterpillar tracks
  
• Dual front brushes
  
• 100W suction motor
  
• 4.5L filtration basket
  
• Dual-layer filtration
  
• Multiple navigation sensors
  
• Infrared sensing
  
• Ultrasonic sensing
  
• Automatic waterline docking
  
• Integrated control panel
  

The wireless design also simplifies storage by eliminating the need to manage a long pool-cleaning cable.

Ease of Use

The BN Pro is designed to minimize hands-on pool maintenance.

Place the cleaner in the pool, select the desired cleaning mode, and allow the robot to perform its cleaning cycle. The app provides additional control and monitoring, while the onboard controls allow basic operation without the app.

When the cleaning cycle is complete, the automatic waterline docking feature helps position the robot for convenient retrieval.
