How to Use This Comparison

  1. Identify your primary application (kitchen exhaust, HVAC, or industrial) — this narrows to 1-2 models immediately
  2. Check your typical duct sizes — the duct diameter range dictates which robots fit your jobs
  3. Assess your volume — high daily volume (5+ jobs/day) favors the K9 for HVAC or CR360 for kitchen exhaust
  4. Consider what documentation your clients require — all Gaolijie robots include HD recording, but ensure you confirm camera resolution and DVR format with your clients' requirements
  5. Bundle supporting equipment — a robot without a HEPA dust collector (for HVAC) or spray system (for kitchen exhaust) is an incomplete solution
