This is my second purchase of this product. I purchased it again after the first one died hoping they improved upon their battery. But that is not the case.The sweeper works wonderful...the first several months. I haven't found anything comparable to picking up dog hair on hardwood floors yet. Unfortunately, the battery only lasts about a year. You might get about 60 seconds of swiffing from one 18 hour charge. I have a small house...steps, LR and DR and the charge runs out by the time I get down the steps and start the LR.DO NOT WASTE YOUR MONEY~! This is an expensive product that will only last a year. I hope someone can recommend a better product for us pet owners with hardwood floors.
