What this part does Replaces the Roomba chargingdetection sensor assembly used to find and dock with the charging base. Interfaces and mounting holes match Roomba 500–900 series units and specific models including 760, 761, 770, so installation aligns with original fit. Key benefits — why you need it Restores reliable docking and charging when the original sensor is damaged or malfunctioning. Improves charging accuracy by quickly detecting base signals, reducing missed docks and interrupted cleaning cycles. Maintains performance in everyday home environments by resisting common sources of interference. How it solves common problems Replaces worn or broken sensors to stop wandering or repeated search cycles when returning to the charger. sensitivity infrared detection helps the robot find the base sooner, shortening recovery time and preserving battery life. Antiinterference circuitry reduces false signals caused by dust and ambient light so the robot docks more consistently. Important attributes Function: sensitivity infrared sensor assembly for chargingbase detection and guidance. Compatibility: Designed for Roomba 500–900 series; direct fit for models such as 760, 761, 770. Sensor interfaces and mounting holes align with original parts. Material and durability: Insulated, moistureresistant housing with sealed internal components to withstand daily dust exposure and minor impacts. Performance: Rapid signal recognition and stable transmission through builtin antiinterference circuitry to ensure accurate charging positioning. Practical use scenarios a cracked or nonresponsive sensor after a bump or fall so your Roomba can reliably to the dock. Install as part of routine maintenance in homes with pets or heavy dust to reduce docking errors caused by debris or stray light. Equip workshop or refurbishment units to restore factorylevel charging performance during or resale. Short installation note Interfaces and mounting points match original Roomba parts for straightforward replacement; follow your model's service instructions for safe installation. This sensor assembly restores accurate charging detection and consistent docking behavior for compatible Roomba models while offering durable protection against everyday dust and minor impacts.
