This universal crevice nozzle supports dual compatible diameters of 32mm and 35mm, matching most mainstream household vacuum cleaners as multi-scene gap cleaning accessories. Ultra-thin flat tip design penetrates tight gaps including window sliding tracks, sofa slits, cabinet seams and appliance edges inaccessible to regular round brush heads. Smooth inner pipeline minimizes airflow loss, maintaining consistent powerful suction to suck up embedded fine dust, crumbs and lint hidden in narrow crevices. High-strength integrated plastic molding resists scratches and deformation from repeated friction with hard furniture edges for long-term daily cleaning use. Two-size conversion interface fits vacuum hoses of different calibers without extra adapters, allowing quick plug-and-play installation for efficient targeted deep cleaning. Set includes 3 vacuum brush nozzle attachments with adapter fittings. Comes with 32mm and 35mm adapters to fit different hose sizes. Brush nozzles help remove dust and debris from various surfaces. Designed as replacement attachments for cordless or canister vacuums. Quick to switch between nozzles for different cleaning tasks.
