Purpose and benefit Keeps the vacuum head close to the floor for better suction: an elastic telescopic wheel mechanism automatically adjusts height to match floor flatness, maintaining close contact between the vacuum port and the surface for improved cleaning performance. Improves traction and durability: wheel surfaces are made from rubber or silicone to increase friction on smooth floors (tiles, wood) and resist wear for a longer service life. Ensures reliable movement under load: wheels are built to support the full weight of the robot vacuum, including dust bins and batteries, maintaining stable driving without deformation or damage. Enables agile navigation: front universal wheels rotate 360 degrees while the unit is rearwheel drive, allowing the vacuum to maneuver through narrow spaces and around obstacles. Key features (function, material, performance) Elastic telescopic function: automatically adapts wheel height to uneven floors so the main body stays level and the suction port remains effective. Antislip surface: rubber and silicone wheel treads increase grip on smooth surfaces to reduce slipping and improve directional control. Wearresistant construction: materials and manufacturing extend wheel life and reduce the need for frequent replacement. Strong loadbearing design: engineered to support the vacuum's full payload (dust box, battery, chassis) while preserving shape and drive stability. Universal front wheels: 360degree rotation for flexible turning and easy passage under furniture and around corners. Lowprofile design: keeps the chassis close to the floor for consistent suction while still allowing movement across threshold and carpet edges. Why you need it Better cleaning results: height adjustment keeps the suction port sealed against the floor where it counts, improving pickup of dust and debris. Safer movement on different floors: enhanced traction reduces slips and erratic driving on tiles and wooden floors. Longer service life: wearresistant materials mean fewer maintenance interventions and lower longterm cost. Reliable operation under load: supports batteries and dust boxes without sagging or compromised mobility. Practical applications / scenarios 1. Cleaning under low furniture: the lowprofile, 360degree front wheels and telescopic adjustment let the vacuum slide under sofas, beds, and cabinets while maintaining suction. 2. Smooth floor cleaning: on tile and hardwood, rubber/silicone treads prevent slipping during fast turns and keep the vacuum on course for consistent coverage. 3. Busy homes with heavy dust boxes: strong loadbearing wheels maintain stable movement when the dust bin is full or larger batteries are installed, avoiding deformation or drive failure. Compatibility and care notes Designed for robot vacuum systems with telescopic or universal wheel assemblies and rearwheel drive configurations. Clean wheel treads regularly to maintain traction and inspect for wear; when significant wear affects floor contact or mobility. This wheel design prioritizes consistent suction, traction on smooth floors, durable materials, and flexible navigation to improve overall vacuum performance and reliability.
