KT-925 Remote Control HVAC Duct Cleaning Robot With Camera And LED

The KT-925 brings battlefield-grade navigation to everyday duct maintenance. Measuring only 310 mm long and 200 mm high, this 9 kg crawler slips through 160 mm access ports that older robots can't breach. Once inside, dual high-torque tracks drive the chassis across corrugated metal, flexible liners, and even damp fiberglass without slipping, while the 360° Z-axis turret spins a nylon or wire brush at a user-defined 0–1 400 rpm.

A 1080p micro-camera paired with six white LEDs beams a live feed to a handheld remote operating up to 1 km away, letting technicians pinpoint grease pockets and mold colonies without crawling through confined spaces. The same remote toggles between manual steering for tight corners and an auto-pilot mode that follows pre-mapped routes, reducing operator fatigue on long commercial runs.

An integrated ozone generator delivers 300 mg/h bursts to sanitize surfaces after debris is loosened, cutting odor-causing bacteria without secondary chemical fogging. When the cycle ends, the robot reverses itself to the access point, automatically retracting its cable onto an onboard spool to prevent tangles. Built-in temperature sensors pause operation if airflow exceeds 60 °C, protecting both electronics and duct integrity. By combining compact size, remote precision, and on-board disinfection, the KT-925 helps facility managers complete inspections and cleanings in a single visit, slashing downtime and labor costs while meeting increasingly strict indoor-air-quality regulations.
