Duct Cleaning Robot Technical Specifications: The Engineers Complete Comparison Guide

Beyond the Sales Brochure: What Engineers Actually Need to Know

When you are evaluating a capital equipment purchase in the $3,000 to $15,000 range, marketing claims are not enough. You need torque curves, motor specifications, camera resolution data, and material certifications. This guide provides the technical depth that engineers and technical procurement teams require to make an informed decision.

Motor and Drive System

Why It Matters: The motor determines whether your robot can push through heavy grease buildup, climb vertical sections, and maintain consistent brush speed under load. An underpowered motor means slower cleaning, incomplete results, and more passes per section.

Key Specifications to Compare:

• Motor type: DC brushed (lower cost, higher maintenance) vs. DC brushless (higher efficiency, longer life, quieter)
• Rated torque: Measured in Nm. Higher torque equals better heavy-load performance. Gaolijie E200 delivers 2.5x the torque of standard models.
• Speed control: Variable speed (0 to max RPM) vs. fixed speed. Variable speed lets operators match brush speed to contaminant type.
• Duty cycle: Continuous vs. intermittent. Continuous-duty motors can run all day on a job site.
• IP rating: Ingress protection. IP54 minimum for wet duct environments. IP65 for washdown applications.

Camera and Inspection System

Why It Matters: The camera is your eyes inside the duct. Without quality imaging, you cannot verify cleaning completeness, document results for clients, or diagnose problems before they become emergencies.

Key Specifications:

• Resolution: Minimum 720p HD. 1080p Full HD is standard on all Gaolijie models.
• Sensor type: CMOS (most common, good low-light) vs. CCD (better dynamic range, higher cost)
• Field of view: Wider FOV (120 plus degrees) captures more of the duct interior in a single frame. Narrower FOV (60 to 90 degrees) provides more detail at distance.
• Illumination: Integrated LED lighting. Look for adjustable brightness to handle both dark ducts and reflective metal surfaces.
• Pan/Tilt: Fixed forward vs. motorized pan/tilt. Pan/tilt cameras let operators inspect side branches and joints without repositioning the robot.

Brush System

Brush Types:

• Nylon bristle (standard): General-purpose. Effective on dry dust and light grease. Gentle on duct surfaces.
• Steel wire (heavy-duty): Aggressive cleaning for heavy buildup, rust, and scale. Use only on steel ducts.
• Abrasive nylon (medium): Silicon carbide-impregnated nylon for moderate buildup without the aggressiveness of steel.
• Spiral brush (round ducts): 360-degree contact. Standard on all Gaolijie round-duct models.
• Flat brush (rectangular ducts): K5-specific. Wider coverage for flat surfaces.

Control System

• Wired remote (included): Reliable, zero latency, no interference issues. Range limited by cable length (20 to 30m).
• Wireless Wi-Fi (optional): Greater mobility. Tablet/phone interface. Potential for signal loss in metal ductwork.
• Joystick control: Proportional joystick for smooth speed adjustment. Standard on all models.
• Emergency stop: Physical E-stop button. Non-negotiable for safety.
