I Researched cordless stick vacuum cleaners and decided on this one after reading reviews. I don't know if my expectations were too high or what but I was not thrilled when I pulled it out of the box; very cheap plastic, and after letting it charge for 12 hours i ended up I charging it for another night hoping that I just didn't have it charged up high enough. It goes at best seven minutes on a full charge and the last three minutes of it are so weak it doesn't even pick up a Pine needle from my fake Christmas tree. I realize that it's not going to be a strong as an electric model and it's more of a light duty sweeper but my $15 Walmart special Bissell 3 in 1 is much stronger. I also have a continuous red flashing light on the charger that I can't find any reason for in the generic manual that comes with it. It has been plugged in and charging for three days now and still flashes even after checking the connection and wiping them off and re- plugging it in. This may just be a defective model , I hope so ,but I'm going to be returning it and exchanging it for a plug in vacuum. My suggestion is if you're not looking for a cordless light duty sweeper buy a sweeper with the roller that moves manually as you push and save some money. I'm so disappointed :(
