KT 928 Compact Flexible Air Duct Sweeper Robot Cleaner System

Meet the KT 928 compact flexible air duct sweeper robot-a lightweight yet powerful solution engineered for fast, thorough cleaning of residential and commercial ventilation shafts. Driven by a high-torque 500 W brushless motor, the unit's omnidirectional rotary brush spins at user-selectable speeds from 200 to 1 200 RPM, adapting instantly to light dust or stubborn, baked-on debris. The 360° swivel head maintains constant surface contact, ensuring maximum agitation and a deeper clean in fewer passes.

A flexible, steel-reinforced drive cable-encased in a heat-resistant polymer sheath-glides smoothly through bends, vertical rises, and narrow plenums up to 20 m from the entry point. Ergonomic, tool-free quick couplers let technicians extend or retract the shaft on site, while the compact 12 kg chassis fits easily through standard access panels and tight crawl spaces.
