NIKRO 862117 Robotic Duct System — Inspect and Air-Wash From One VehicleThe NIKRO 862117 puts a motorized robotic vehicle inside large ductwork to inspect and air-wash in one pass. A camera with variable-intensity lighting feeds the SD recorder while air-whip and blast nozzles knock debris loose off the duct walls. Air-duct cleaning contractors use it in commercial trunk lines that are too large to clean by hand from the registers.NIKRO 862117 Robotic Vehicle and Air-Wash Tooling Motorized robotic vehicle — drives the camera and cleaning heads down a commercial trunk line so you don't work blind from the register Variable-intensity lighting with LED lamp — set brightness to match galvanized or lined duct so the recorded image stays readable Air sweeping broom plus 3-whip nozzle and single air whip — agitate settled dust off the duct walls as the vehicle moves Forward air-blast nozzle — push loosened debris ahead toward the collection point Onboard SD recorder and microphone — capture video and voice notes to document the run for the customer Cord reel and foam-lined carrying case — manage the cable on the job and protect the vehicle and nozzles in transit 862117 Applications and EnvironmentsCommercial air-duct cleaning contractors use the 862117 in large rectangular and round trunk lines in offices, schools, and healthcare and institutional buildings where the ducts are too big to reach by hand. The robotic vehicle carries the camera and air-wash nozzles the length of the run so one operator can inspect and clean from a single access point. Optional coating spray and brushing systems are available to add sealant application or mechanical brushing to the same platform. The SD recorder and microphone let crews document duct condition for building owners and compliance records.
