Very brief period of use. the company's original vacuum cleaner. Only a wired Samsung will do for comparison. Of course, this one is far more practical. No wires or large, mobile cases. The brushes are effective; they gather all the dust, and the vacuum picks it all up. Small, light, and quiet. movement independence. Everything is simple to vacuum, including the floor, walls, ceiling, furniture, cornices, and ventilation grilles. I suggest. Really cozy and thoughtfully designed.
