The first charge took as noted 24 hours, but the recharge didn't work even after being plugged in for 40 hours. Tub cleaning was marginal at best. The only good thing was I didn't have to get on my knees to get the marginal results. I will try to take it back to Bed Bath & Beyond, but since I didn't keep the receipt, I suspect I will have little luck. I'm not going to fool around with buying a new battery.
Bottom Line: No, I would not recommend this to a friend
