Best Battery Life
The Electrolux UltraPower Studio is unique in that it has a replaceable battery. It also has a long run-time of 21 minutes and works great on bare floors.
The replaceable battery costs as much (or more) than the vacuum itself to replace.
Performance: The Electrolux UltraPower Studio tested exceptionally well on bare floors, corners, and pet hair. However, for medium-pile carpet, its not the best product on our list.
Battery Life: This is where this lightweight vacuum shines. With a run-time of about 21 minutes, it keeps its charge longer than most.
Price: This cordless vacuum is one of the pricier models on our list, but still considered a top contender because of its great features.
