• Battery type: Most robot vacuum cleaners use lithium-ion batteries because they have a higher energy density, shorter charging time, and longer cycle life compared to other types of batteries
• Battery life: The capacity of a lithium-ion battery is typically measured in milliampere-hours (mAh) or watt-hours (Wh). The higher the capacity, the longer the battery life
• Charging time: Lithium-ion batteries charge quickly, usually taking 2 to 4 hours to fully charge. Many robots have an auto-charging feature that automatically returns to the charging dock when the battery is low.
• Lifespan & Maintenance Lithium-ion batteries typically have a lifespan of 2 to 5 years, depending on the frequency of use and the number of charges/discharges. Cleaning the charging contacts regularly and avoiding over-discharge can prolong battery life.
