The total battery life of these vacuum cleaners will depend on the time for which you have charged them. This means that if you have single charged them, then this means that the robot will work for around 2 – 3 hours without stopping, and this is because of what kind of battery they have installed inside of it and then if you have charged the machine fully then it will work anywhere from 6 – 7 hours nonstop without stopping or without even needing to be charged, and it has a smart system which means that if the battery of the system is low, it will give a message to the owner and then they have to decide whether to stop the operation and send the robot back to their charging station or their charging pod or else order it to keep on working until the whole battery drains out. Another thing is that you don’t have to worry about charging them from time to time and that too physically because they have a smart charging station or pod that comes with it, and also it will automatically go there and get charged to be used.
