Device selected for its low noise announced: the engine noise is actually highly attenuated; however, the suction of air by the brush remains noisy but acceptable manner. Sufficient power (1800 W): very effective for vacuuming floors, carpets, including dog hair. Handy, not too heavy, very long power cable. The only reservation concerns the price of the bags (microfiber), expensive. Not tried generic brands. Very affordable price from Amazon. Fast delivery.
