Love the Omni-glide as so light and easy to use.  I was so impressed I bought my three children one each and all gave the thumbs up.  One did not work but Dyson exchanged the next day so would always buy Dyson as excellent company.  Have bought many of the Dyson hoovers from the ball to the small ball which is excellent and most of the handhelds but think the Omni-glide for hard floors is a brilliant invention.  Battery lasts for several large rooms - I have used also on stairs which works really well due to the swivel head.  I cannot recommend enough for hard floors.
