It recharges itself when needed. We use ours three times a week and after two years it’s still charging/ holding a charge.
Sorry, there was a problem. Please try again later.I am not sure what battery it uses but I know that its charge is pretty decent, my apt is 900 sq. ft. and to vacuum the entirety of it it uses roughly 25% battery life. Then it docks and recharges itself.
