Duct Cleaning Robot Accessories and Attachments: Complete Guide to Brushes, Cameras, and Tools (2026)

The Right Attachment Can Double Your Robot Capability

Your duct cleaning robot is a platform. The attachments and accessories you pair with it determine which jobs you can handle, how fast you can work, and how thoroughly you can clean. A $200 brush upgrade can cut cleaning time by 30% on certain duct types. A $500 camera upgrade can be the difference between winning and losing a hospital contract. This guide covers every accessory and attachment available for Gaolijie robots and when each one earns its keep.

Brush Types: The Most Important Accessory Decision

Camera Systems

• Standard Fixed 1080P: Forward-facing, fixed position. Adequate for routine HVAC cleaning inspection. Standard on K7S.
• Pan-Tilt-Zoom (PTZ) 1080P: Remote-controlled pan (360 degrees), tilt (90 degrees), and optical zoom. Enables detailed inspection of side walls, joints, and hard-to-see areas. Standard on CR360 Advanced and E200 Professional. Strongly recommended for any contractor doing NFPA 96 compliance work — fire marshals appreciate being able to see duct seams and welds clearly.
• Infrared/Thermal Camera Add-on: Detects temperature anomalies that indicate grease buildup (grease insulates differently than clean metal), air leaks at duct joints, or moisture intrusion. Specialized tool for high-end commercial and industrial inspection work.

Cables and Control Extensions

• Standard 15m cable: Sufficient for most restaurant kitchen exhaust systems and small commercial HVAC ducts.
• Extended 20m cable: Recommended for larger commercial kitchens and medium commercial HVAC systems. Standard on CR360 Professional and K7S Complete.
• Extended 30m cable: For large commercial kitchens, hotel exhaust risers, and industrial ducts. Standard on CR360 Advanced. Necessary when the access point is far from the cleaning zone.
• Custom cable lengths: Gaolijie can manufacture custom cable lengths for specific applications (high-rise exhaust risers, long industrial pipeline runs). Contact for pricing.

Sprayer Attachments for Robots

• Robot-mounted spray nozzle (D2 compatible): Attaches to the robot and connects to the D2 sprayer via secondary hose. Applies degreaser or sanitizer directly ahead of the rotating brush for simultaneous chemical + mechanical cleaning.
• Fog nozzle attachment: For sanitizing and disinfecting applications in healthcare and food processing ducts. Produces fine mist for complete surface coverage.

Recommended Starter Kit by Business Type

• HVAC-only contractor: K7S with nylon brush + medium steel brush + 20m cable. Total accessory investment: included with K7S Complete.
• Kitchen exhaust contractor: CR360 with stiff steel brush + PTZ camera + 30m cable + D2 sprayer with robot-mounted nozzle. Total accessory investment: approximately $1,200-1,800 beyond base robot.
• Full-service contractor (HVAC + kitchen exhaust): K7S Complete (nylon brush included) + CR360 Advanced (PTZ camera, 30m cable included) + extra stiff steel brush for CR360 + D2 sprayer system. Total accessory investment: approximately $2,000-3,000 beyond base robots.

Accessory Maintenance and Replacement

• Brushes: Replace when bristle length is reduced by 30% or when cleaning effectiveness noticeably decreases. Dull brushes increase cleaning time and motor load.
• Cables: Inspect before every job for cuts, kinks, or exposed conductors. A damaged cable in a greasy kitchen exhaust duct is a safety hazard.
• Cameras: Clean lens before every job with microfiber cloth. Fogged or greasy lens = poor documentation = failed inspection.
• Spare parts inventory: Keep at minimum one spare brush of each type you use, one spare cable, and one spare camera module. Downtime waiting for a replacement part costs more than the part itself.
