Title: Dissatisfaction with battery life Review: My husband purchased the Vac'N'Mop as a tool to minimize the amount of time that I spend cleaning kitchen and bathroom floors. At first the product seemed to be the answer to my cleaning needs. I charged the product as indicated for 24 hours before the first use and used the product without complaint. The product sat for a few days before the next use and when I attempted to use the vacuum, the battery died shortly after turning it on. I re-charged the battery and attempted to use the product again, only to find that within minutes the battery was dead again. I called customer service and was informed that the battery life is 9-13 minutes. Well I don't know about you, but 9-13 minutes is not enough time for me to vacuum the kitchen floors much less mop them. I will be returning the product and going back to the tried and true method of sweeping and them mopping until I find a product that will meet my requirements. Answer:
A:
output: No
