Powerful performance for real world cleaning: The lithium ion battery provides higher voltage and current, giving the vacuum cleaner and sweeping robot stronger suction and better climbing ability to handle complex environments. Longer runtime per charge: A single charge cleans a larger area, reducing the need to to the charging dock midclean, saving time and improving overall efficiency. Plugandplay compatibility: Custom designed for specific models, precisely matched to the vacuum interface for easy installation, allowing users to the battery themselves. Safe and intelligent operation: Builtin Battery Management System (BMS) offers protection against overcharge, overdischarge, overcurrent, short circuit, and temperature risks for safe, reliable performance. Practical use scenarios: Openplan homes: A single charge covers a wide living area, enabling thorough cleaning without frequent interruptions. Pet households: Extended run time efficiently tackles hair and debris across rooms with minimal recharging. Multisurface layouts: Reliable performance on transitions and uneven surfaces, reducing the need for docking on every change of floor.
