We have laminate floors throughout our house.  I use to use a dust mop twice a day, then have to get out the little dust buster to collect what the mop swept up.  Now, I run the Eureka Quick Up Cordless 96JZ throughout the main floor (about 1,500 sq. ft.), flipping on the rotating brush when I get to an area rug.  Using the rotating brush, it does draw a bit more on the battery, but I can still make it all over the main floor on one battery.
