For whatever reason, I've always considered cordless vacuum cleaners to be toys. How, exactly, can a vacuum that runs on batteries compete with one that is plugged into an electrical outlet, particularly when it comes to the task of cleaning carpets? Yet, the Dyson vacuum works without a hitch. To begin, the v15 has a superior level of suction power compared to other vacuum cleaners manufactured by Dyson as well as those manufactured by other companies. Second, the use of motorized nozzles is absolutely crucial. For instance, the carpet nozzle has bristles that are particularly stiff, and it spins very quickly, which practically rips the carpet up as it passes over it. He gets by with a bang despite the presence of two cats in the house.
