Duct Cleaning Equipment Buyer's Guide: Robots, Vacuums & Accessories

Equipment Categories

Professional duct cleaning requires three core equipment categories:

1. Inspection equipment — Cameras, borescopes, robot-mounted cameras
2. Cleaning equipment — Robots, brush systems, pressure washers, sprayers
3. Collection equipment — HEPA vacuums, negative air machines, dust collectors

HEPA Collection Systems

Why HEPA is Non-Negotiable

Standard shop vacuums exhaust fine particles back into the air. HEPA filtration (99.97% at 0.3 microns) is required for:

• NADCA-compliant HVAC cleaning
• Healthcare facility work
• LEED-certified building maintenance
• Post-construction cleanup

Key Specifications

Specification	Entry Level	Professional
Airflow (CFM)	1,000-1,500	2,000-4,000+
HEPA efficiency	99.97%	99.99%
Filter stages	2 (pre + HEPA)	3+ (pre + HEPA + carbon)
Noise level	75-85 dB	65-75 dB
Price (factory-direct)	$1,500-$2,000	$2,500-$4,000

Sprayer & Pressure Washer Systems

Chemical Sprayers (for Degreasing)

• Electric airless: Fine mist, consistent coverage
• Compressed air: Lower cost, higher maintenance
• Foamers: Extended contact time for heavy grease
• Price: $500-$1,200

Hot Water Pressure Washers

• Temperature: 80-95°C recommended for kitchen grease
• Pressure: 1,500-2,500 PSI (higher can damage ducts)
• Flow rate: 10-15 L/min
• Price: $1,500-$2,500 factory-direct

Keys to Smart Purchasing

1. Buy factory-direct — Eliminate distributor margin (save 30-50%)
2. Prioritize camera quality — 1080P HD video is a revenue tool, not a cost
3. Check warranty terms — 1-year comprehensive minimum, parts availability within 48 hours
4. Verify pre-shipment testing — Each unit should have documented burn-in testing
5. Assess training support — Video training + optional live remote sessions
