It has been 4 weeks now and my experience is amazing with this. I can clean my house twice with minimum speed and the dirt picking ability is just awesome. It is also good for cleaning car interior. This needs to be done on high speed so the number of minutes for which the machine can run will reduce. Also I am getting a charging time of 45 mins until battery goes full. I definitely recommend this product. It seems Samsung is also nailing the cordless vacuum as well and beating the competition with a good product at half the price.
