INSPECTo-DDuct Inspection & Cleaning Robot
The challenge
Narrow, dark and hard to reach, so ducts get neglected.
Dust, mould, heights and tight spaces.
Dirt and mould grow where no one looks.
Opening ceilings is slow and disruptive.

How it works

The robot enters through an existing maintenance hatch, with no need to open ceilings.
A tether reel feeds the robot along the duct between the intake fan and air filter.
The operator drives it from a handheld display and wireless controller, inspecting and cleaning as it goes.
Recorded footage and findings are shared so you can plan follow-up maintenance.
Modular design
Swap between the cleaning and inspection modules on the same INSPECTo-D base.

Low-profile tracked chassis with camera arm, lights and quick-mount points.

Rotary brush for removing dust and debris from duct walls.

Pan-tilt dome camera for detailed visual inspection.
System
Every kit is configured to your ducts. A typical setup includes:
Dimensions and performance figures are available on request.
FAQ
INSPECTo-D is designed for narrow spaces such as air ducts. Share your duct dimensions and layout, and we will confirm the right configuration.
Yes. The same base takes a cleaning module with a rotary brush and an inspection module with a pan-tilt dome camera, so one robot covers the whole job.
Through an existing maintenance hatch. A tether reel feeds the robot in, and the operator drives it from outside with a handheld wireless controller.
Yes. Footage from the inspection camera is recorded, and findings can be compiled into an inspection report for your maintenance records.
Yes. A2tech is based in Johor, Malaysia, and provides operator training and local support for our robots.
