Product Notes
TECHTONGDA Commercial Duct Cleaning Equipment suit Dia. 100-800mm Wipe Cleaner

This machine is a serious investment for facilities with air duct systems. It combines a flexible rotating brush with a high-efficiency vacuum, so it can loosen and collect debris in a single pass. The adjustable 0-1000 RPM gives you control over different duct sizes, and the 2MP camera with 11-inch monitor provides real-time visibility of the interior. It is designed for a single operator, which reduces labor overhead. At USD 5,500.68, the price tag is the most obvious limitation, but this is a purpose-built system for repeated commercial use. It runs on 110V power and comes with a 6-month warranty.
Zep 50-lb Floor Hard Floor Sweeping Compound Dust Control Industrial Cleaner

This is a straightforward dust management tool for hard floors. Spread it across cement, concrete, unfinished wood, or marble, and it holds down dust as you sweep. The non-toxic, residue-free formula leaves no slippery coating, and the 50-pound container means you will not run out quickly. It requires no electricity or equipment setup, so any crew member can use it. The limitation is that it only addresses floor surfaces; it will not help with duct interiors. Also, this compound carries no certifications or listings, which could matter if your facility needs documented compliance.
Final Choice by Use Case
Choose the TECHTONGDA if your priority is cleaning HVAC ducts between 100 and 800mm and you need a machine that can do the job with a single operator. Choose the Zep sweeping compound if you are looking for a simple way to keep dust under control during routine floor sweeping. Match the tool to the surface, and you will get reliable results.
