KT-976 Central Air Conditioning Main Duct Cleaning Robot: Simultaneous Brushing and Vacuuming,

When considering the purchase of a robot for central air conditioning main duct cleaning, the key factors are not simply whether the robot can enter the duct. More practical considerations include: can it clean the duct ceiling? Can it vacuum simultaneously after brushing? Can the duct interior be observed in real time? Can the equipment be operated remotely? And can the cleaning process be documented with video?

Addressing these actual operational requirements, Anhui Kuaitong Pipeline Cleaning Technology Co., Ltd. has developed the KT-976 Central Air Conditioning Main Duct Cleaning Robot.

The KT-976 integrates robotic locomotion, liftable mechanical brushing, dual-direction (top and bottom) simultaneous vacuuming, 1080P front and rear cameras, LED lighting, remote control, a host computer system, and video recording into a single unit. It is primarily designed for cleaning central air conditioning main ducts with heights ranging from approximately 250–800 mm.

1. Which Customers Is the KT-976 Suitable For?

The KT-976 is intended for the following customer groups:

Central Air Conditioning Cleaning Service Companies
For professional duct cleaning companies, equipment must meet requirements for continuous operation, ease of use, and project documentation. The KT-976 handles brushing, vacuuming, video inspection, and recording, making it suitable for professional duct cleaning projects.

Property Management Companies
Central air conditioning systems in large commercial buildings, office towers, and hotels require regular maintenance. The robot can enter the main duct through access ports and be operated from outside the duct.

Commercial Complexes
Shopping malls have large-area main ducts with long routes, making manual cleaning labor-intensive. The 15 m working range extends coverage from a single access point.

Hospitals, Schools, and Public Buildings
For projects that require controlled working environments and minimize personnel entry into ducts, remote robotic cleaning offers significant value.

Industrial Facilities and Mines
Ventilation ducts in industrial environments may accumulate heavy dust over time. Mechanical brushing combined with simultaneous vacuuming improves cleaning efficiency.

2. What Problems Does the KT-976 Address in Traditional Duct Cleaning?

Duct ceiling too high to reach
The KT-976 features a liftable large cleaning brush that can be adjusted to match duct height.

Dust scatters after brushing
The equipment performs brushing and vacuuming simultaneously. After the brush loosens dust, the upper and lower vacuum ports collect it promptly.

Too dark inside the duct to see cleaning results
The robot is equipped with 1080P front and rear high-definition cameras and 4 high-brightness LED lights. Operators can view the interior through a 10.1-inch display.

Personnel access to ducts is inconvenient
After the robot enters the duct, it can be remotely controlled from outside.

Limited cleaning reach from a single access point
The KT-976 comes with a 15 m working hose, extending coverage from each access opening.

3. Core Configuration and Functions of the KT-976

1. Mechanical Brushing + Simultaneous Vacuuming
The KT-976 features an integrated brushing and vacuuming design. The cleaning brush rotates at high speed to detach dust from the duct walls, while the vacuum system simultaneously collects the loosened debris. Compared with separate brushing followed by vacuuming, this reduces work steps.

2. Liftable Large Cleaning Brush
The front large cleaning brush can move up and down. The equipment is suitable for main ducts with heights of approximately 250–800 mm, allowing brush position adjustment based on actual duct height. A nylon strip brush is also provided at the bottom for floor cleaning.

3. 1080P Front and Rear Dual Cameras
Two high-definition cameras at the front and rear respectively assist in observing the environment ahead and behind the robot. Operators can view in real time:

Dust accumulation inside the duct

Robot position

Obstacles ahead

Areas already cleaned

The cleaning process

This enhances operational visibility.

4. 10.1-Inch High-Definition Display
The equipment is equipped with a 10.1-inch HD LCD display. Operators can view the robot's interior work from outside the duct without frequent entry for inspection.

5. 4 High-Brightness LED Lights
Ducts typically have no natural light. Four high-brightness LED lights work with the HD camera system to provide illumination during robot operation.

6. Remote Control
After the robot enters the duct, operators can control travel, brushing, and brush lift functions from outside the duct. This is especially important for large ducts, long runs, and scenarios where personnel access is difficult.

7. Self-Developed Host Computer System
The KT-976 features a host control system that integrates equipment control, video display, and project documentation. For professional cleaning companies, this can be further used for process management and project record retention.

8. 15 m Long Working Range
The equipment comes with a 15 m working hose. After entering through the access port, the robot can continue deeper into the duct, reducing the need for frequent equipment repositioning.

9. Maximum 45° Climbing
The KT-976 has a maximum climbing angle of 45°, with non-slip wheels and a drive system that adapts to ducts with slopes or localized obstacles.

10. 24V Low-Voltage Power Supply
The robot operating end uses 24V low-voltage power, with operators controlling it remotely from outside the duct. This design reduces the need for personnel to enter the duct interior.

4. KT-976 Main Technical Specifications

Parameters based on KT-976 product documentation.

5. Key Considerations When Purchasing the KT-976

When selecting a central air conditioning duct cleaning robot, the following indicators should be carefully evaluated:

① Duct height compatibility
The KT-976 is suitable for main ducts with heights of approximately 250–800 mm.

② Ceiling cleaning capability
For higher ducts, equipment with a liftable brush mechanism should be prioritized.

③ Simultaneous vacuuming requirement
If the project demands strict dust control, integrated brushing and vacuuming equipment should be chosen.

④ Video documentation for acceptance
If the cleaning project requires presenting before-and-after results to clients, 1080P video recording capability is more practical.

⑤ Long-range operation requirement
For long ducts in large shopping malls, office buildings, and industrial facilities, a 15 m working range reduces frequent repositioning.

⑥ Sloped ducts
If the project involves sloped ducts, the robot's climbing and traversing ability should be considered.

6. Applicable Industries for the KT-976

The KT-976 can be used in:
