Improved efficiency: Extended battery life and stable suction power reduce the need for mid cleaning charging, prevent interruptions, and save time during repetitive cleaning tasks. Multiple protections: The vacuum cleaner battery includes over charging, over temperature, and over discharging protections, making it safe and reliable to use. Extend service life: Aging batteries may exhibit voltage instability and short circuits that can indirectly damage core components such as motors and control boards. Fast charging: The vacuum cleaner battery supports fast charging technology, enabling a full charge in a short period and reducing waiting time. Optimized charging quickly replenishes power for convenient use. Use scenario: Regular home cleaning with pets or traffic areas where longer run time and stable suction help complete cleaning with fewer interruptions. Use scenario: Office or retail space maintenance that requires reliable daily performance with built in protections against overheating and over charging. Use scenario: Large homes or multi room cleaning where fast charging reduces downtime between rooms and keeps cleaning flow smooth.
