I've
had the cordless pink Dyson DC16 Root 6 Vacuum
for a little while and everyone in my family loves it, including the kids.  We have two hand vacuum's and 9 times out of 10, the Dyson is the vacuum we use.  This hand vacuum has uses Root Cyclone technology and has great suction, about twice the suction of other hand vacuums and it recharges about 3 times faster. and tools to make cleaning easier in tight spaces, as well as on hardwood floors.  
The Lithium ion battery lasts for 6 minutes or so giving amply time to clean small messes hand vacuum's are intended for.  The battery charger can be wall mounted and the vacuum features a low-battery indicator which is awesome for me because my 9 year old forgets to put the vacuum on the charger and I can tell how much battery is left.  
The DC16 is a bagless hand held vacuum cleaner and has a 1-touch cup-emptying system which I LOVE!  The 1-touch emptying system is great for those of us who make our kids vacuum their own small messes because they can easily empty the vacuum themselves.  Image that!

You can buy the pink Dyson DC16 Root 6 Vacuum

$10 of each hand vac purchase to The Breast Cancer Research Foundation
for a total donation of $1.4 million
