First time i have bought a battery powered vacuum and i am giving this review after 3 months of use. The vacuum is amazing. If you use it on max speed it will last 5 to 6 minutes, the medium speed lasts 20 minutes. Medium speed is the perfect speed for vacuuming the house or the car as it sucks dust and dirt very efficiently. I'm giving it a 4 star because it did not come with any accessories so i had to buy the combination tool and the extension crevice tool from the official samsung part supplier nz. Its a fantastic vacuum no doubt.\ Thanks
