Cordless gifts for "olders"

There are so many wonderful house cleaning helps that I am discovering.  The newest is the great steam floor mop by Shark.  It sanitizes with no soap,and no puddles on the floor that you have to wait to dry.  I'm in!  Of the conveniences that I have, I wish some of them were cordless because it is easy to get your feet tangled up in the cord as you are working.  If you are considering a "cleaning" gift for an older person, you might want to consider cordless if it is available.  It has to be recharged, but moves with you without your being tethered and tangled.  Just a thought!
