After reviewing all the cordless vacuum cleaners online, i decided to buy this Electrolux Ergorapido.  It is beautiful, powerful yet lightweight and the charge lasts nearly an hour.  It can transition easily from carpet to bare floors with no effort.  I love the hand-held portable feature for my furniture and car.  It is really two vacuum cleaners in one!  I am a senior with arthritis and the Ergorapido totally does the job with no heavy lifting, easy maneuverability and no cord to tangle and rewind.  This sweeper has changed a dreaded chore into an easy duty.  I am so pleased with this vacuum and have recommended it to everyone in my family.
