Advantage of lithium ion battery for ground clean machine Cycle life more than 3000 cycles, long service life, and do not need change battery during the entire service life of floor cleaning machine. Flexible charge is available, such as charge during change water or rest. Don't worry about forgetting to charge or running out of battery.Maintenance free, Don't worry about charging during long time of storage. The price of the lithium ion battery is more competitive in the entire service life of the Floor cleaning machine.
