• Battery type: Most robot vaumers use lithium-ion batteries because they have higher energy density, short charging time, and long cycle life than other types
• Range: The capacity of a lithium-ion battery is usually measured in milliampere-hours (mAh) or watt-hours (Wh). Higher capacity means longer working hours, and common robot vacuums have a battery life of between 60 and 120 minutes.
• Charging time: Lithium-ion batteries charge quickly, in general, it takes 2 to 4 hours to fully charge. Many robots have an automatic recharge function, which will automatically return to the charging dock when the battery is low
• Lifetime & Maintenance Lithium-ion batteries typically have a lifespan of 2 to 5 years, depending on the frequency of use and charge-discharge cycles. Regular cleaning of the charging contact points, as well as avoiding over-discharge, can extend battery life
