Compatible For Mi 1s 1st — Replacement Laser Head Key benefits Restores accurate navigation and mapping for Mi 1s 1st robot vacuums by replacing worn or damaged laser heads. Easy swapin replacement: designed for straightforward removal of the old laser head and installation of the unit. Reliable performance matched to vacuum cleaner operation to maintain stable room scanning and obstacle detection. speed scanning capability: scans the room at a speed of 5 x 360 degrees/second to collect distance information for mapping and path planning. What it does Replaces the laser distance sensor (LDS) assembly used by the Mi 1s 1st to measure distances and build room maps. Ensures the vacuum can continue to detect obstacles and navigate efficiently without misalignment or mapping errors. Compatibility and fit Compatible For Mi 1s 1st (designed to match the original form and function for this model). Intended as a direct replacement for the Mi 1s 1st laser head; verify model designation before . Performance and reliability Provides stable scanning performance consistent with the vacuum cleaner's mapping system. Restores the vacuum's ability to obtain accurate distance information at the specified scan rate. Typical use scenarios a damaged or nonfunctioning laser head after a collision or wear to restore navigation and mapping. Routine maintenance to renew sensing performance and extend the usable life of a Mi 1s 1st vacuum. or refurbish Mi 1s 1st units in home service or small shops to units to factorylike navigation behavior. Simple buying checklist Confirm your vacuum model is Mi 1s 1st. If your robot shows mapping errors, frequent collisions, or failure to create correct room maps, replacing the laser head is a practical first step. Notes This item is the replacement laser head assembly for Mi 1s 1st and is intended to match the original function and scan specifications. Installation may require basic disassembly; consult instructions or a technician if needed.
