Cordless vacuums have improved significantly in recent years and many models are now capable of providing equivalent levels of cleaning performance to corded vacuums.
Some cordless vacuum models even have the suction power of an average corded upright vacuum.
However, whether a cordless vacuum is as good as a corded vacuum largely depends on your specific cleaning needs and preferences.
Corded vacuums don't have the same runtime limitations as cordless vacuums, as they can operate for as long as you need them as long as they are plugged in.
On the other hand, cordless vacuums are much more convenient to use, as they don't require a power outlet and can be easily moved around your home. They are also generally lighter and more maneuverable than corded vacuums, which can make them easier to use in tight spaces or on stairs.
Ultimately, the choice between a corded or cordless vacuum depends on your specific needs and preferences.
