Of course, the cordless is modest. The cordless is a relatively new invention that came up to make cleaning flexible and less tiring. The stress of getting wires entangled while cleaning and the need to change the socket will be forgotten. While the powerful suction of the cordless may be low, companies are continually improving to ensure they do the same work as the corded. If you have heavy cleaning duties or want to use a vacuum for commercial purposes, get a corded vacuum with a long power cord for extended reachability.
