✔ Fits 200–750mm Ducts ✔ 5 Cleaning Modes ✔ No Dust Spreading
Our pipe cleaning robot is designed with a modular structure and multi-functional cleaning system, allowing users to easily switch different cleaning modes according to pipe conditions and cleaning requirements. It is ideal for ventilation ducts.
1. Dual Side Brush Mode (with lifting function)
Equipped with two powerful side brushes, the robot can effectively clean large areas of pipe walls. The lifting swing arm allows the brushes to adjust their angle, ensuring thorough cleaning even in uneven or complex pipe structures.
2. Single Brush Mode (with lifting function)
The large brush head provides stronger cleaning force and wider coverage, ideal for removing heavy grease, stubborn dirt, or thick deposits inside pipelines.
3. Small Brush Mode (compact structure)
This configuration uses a single brush head, making the robot more flexible and suitable for narrow pipelines or precise cleaning tasks.
4. Dual Bottom Brushes
Two additional brushes at the bottom help clean sediments and residues at the base of the pipe, achieving 360° full-coverage cleaning.
5. Inspection Mode
The robot can also operate in inspection mode, equipped with a high-definition camera to monitor pipeline conditions in real time, making it suitable for inspection and maintenance work.

1. Will the robot cause scratches or damage to the inner walls of the pipes?
This robot uses nylon material brush, which is soft and will not cause scratches or damage.
2. Will dust or pollution be generated during the cleaning process? How is it handled?
The professional robot is equipped with a negative pressure dust collection system, which can suck dust and debris into the dust collection box while cleaning, preventing dust from spreading outside the pipes.
3. Which types of central air conditioning ducts are suitable for cleaning with the robot?
The robot is suitable for 200 to 750mm central air conditioning ventilation duct systems, such as supply/return air ducts in commercial buildings (shopping malls, hotels, office buildings), hospitals, schools, factories, and other central air conditioning systems.
4. So this link includes Q38 robot, control box and vacuum suction machine?
This link only includes robot and control box. You should purchase vacuum suction machine separately.
5. How can we inspect the cleaning process?
This robot is equipped with 3 HD cameras. You can inspect the process through the screen of control box.
6. Does the Q38 need a vacuum machine to work?
Yes. The Q38 brushes dust loose and the debris must be extracted with a vacuum
machine. The W40 is recommended and can collect both dry dust and oil-based residue.
7. What are the 5 cleaning modes of the Q38?
1) Dual side brush mode with lifting function for large wall areas,
2) Single large brush mode for heavy dirt and thick deposits,
3) Small brush mode for narrow or precise cleaning,
4) Dual bottom brushes for sediment at the duct base,
5) Inspection mode for real-time duct monitoring.
Q8. Can the Q38 clean ducts with bends and obstacles?
Yes. The robot has anti-slip rubber tracks and obstacle-crossing ability. The lifting swing arm keeps the brushes in contact with the duct wall in uneven sections.
Q9. How much does the Q38 cost?
The Q38 is quoted per configuration (brush set, cable length, W40 vacuum).
