1pc spliced climbing pad step bar kit for sweeping robots — smooth, durable threshold ramp that helps your robot cross doorways and small elevation changes without getting stuck. Why you need this Prevents your robot from stalling on door thresholds, rugs, or floor transitions by providing a gentle fullangle slope and rounded edges that guide wheels up and over obstacles. Reduces interruptions to cleaning cycles and protects brushes, sensors, and drive motors from repeated impacts at thresholds. Works on multiple floor types—tile, wood, and carpet—so one accessory improves performance across your whole home. Key benefits and features Functional design: Fullangle slope and rounded edges allow smooth, predictable wheel contact so cleaners can climb up to 2 cm obstacles reliably. Durable material: Made from longlasting silica gel that resists wear and deformation, maintaining stable performance over time and across different floor surfaces. Modular and adjustable: Spliced, modular pieces enable quick width adjustment to match different doorways or passages. Tool installation: Installs easily without tools and locks in place to stay secure while your robot operates. Broad compatibility: Compatible with general models of sweeping robots for easy integration without modelspecific modifications. Performance highlights Supports obstacle heights up to 2 cm to reduce instances of getting stuck. Stable traction on tile, wood, and carpet due to silica gel surface. Keeps its shape and function after repeated use and robot crossings. Practical use scenarios Between rooms with different floor heights: Install the step bar at door thresholds so your robot crosses from tile to carpet without stopping. Over area rug edges or small carpet transitions: Place the ramp where rugs tend to lift so the robot can climb on and off smoothly. At sliding door tracks or raised treads: Use the modular bar to bridge shallow tracks and prevent the robot from catching on the edge. What's included and installation 1pc spliced climbing pad step bar kit that can be assembled or shortened to fit the required width. No tools required for installation; simply adjust the spliced segments, position the ramp at the threshold, and the pieces hold securely during operation. Material and compatibility summary Material: Longlasting silica gel, wearresistant and deformationresistant. Compatible with: General models of sweeping robots. Obstacle capacity: Enables navigation over obstacles up to 2 cm . Floors: Designed for tile, wood, and carpet. This step bar is a practical, durable accessory to improve your robot's mobility, reduce cleaning interruptions, and protect its components at thresholds and floor transitions.
