Magnetic Boundary Replacement Strip for Robot Vacuums Function Replaces the magnetic strip of the vacuum cleaner to restore or establish a virtual wall boundary and nogo zones. Compatibility Designed for robot vacuums that use magnetic boundary strips for virtual walls; suitable for models that rely on standard magnetic strip systems. Size Available in standard widths used by common magnetic boundary setups; exact dimensions vary by model. Material Magnetic strip material chosen for durability and reliable boundary detection during operation. Performance Delivers consistent magnetic cues for accurate boundary recognition, helping prevent unintended boundary crossing and enabling flexible room configuration. Use scenarios 1) Block off a pet area or spaces with cords by placing the strip along doorways or thresholds to keep the vacuum out. 2) Create a boundary around delicate rugs, plants, or electronics to protect them during cleaning. 3) worn or damaged boundary strips when reconfiguring a room after moving or changing layouts.
