How: The size, how the handle folds, how the handheld vacuum is part of the main vacuum. Dislikes: Suction power, not as light as advertised. Vacuum with a handheld vacuum. I have owned 2 Dyson vacuum cleaners for many years. One in the house and one in our camper. When one of them died, I looked at many cordless vacuums looking for a replacement. Bissell has a great name so I went with this model but the suction power is just terrible! I use it every day and then do a deep cleaning with a regular vacuum once a month. It copes well with dust and hair, but does not always pull in fine sand, grass or pine needles. I tried using a handheld vacuum in the car. and I gave up, it was so bad. I do NOT recommend this product AT ALL!
