This vacuum cleaner is perfect if you can be there when it works. However, don't plan to run it while you're busy or away from home. He insists on going to places where he gets stuck and drains his battery without doing anything. You can literally point it at the other side of the house and it will head straight for the area under the sofa where it gets stuck or the wires where it likes to get tangled. So 4/5. Good suction, good battery but brainless. I will definitely keep it until it wears out; then I will buy a smarter model.
