We purchased this machine to spot clean when our puppy has accidents during potty training...our toddler is also a little messy and need to spot clean. We have fully charged the machine numerous times. Every time we charge and then use, we have to recharge for a quick 30 sec cleaning. The battery does not hold a charge. We plug it in and see the 3 lights turn on unplug and use. If i turn it off to move to another spot, I have to plug it in and see the 3 lights again unplug and use. The machine is not even a year old.
