This will save you much time and effort.
And you can also remove the wand, and insert the handle directly into the motorized cleaner head to clean carpeted stairs or other carpeted surface.

DuoClean Technology
Unlike traditional vacuum brushroll design, these vacuums equipped with two working rollers, one bristle brushroll and an additional soft roller, in the cleaner head, both of the rollers spin when cleaning hard floors and carpet. Shark claims that the soft roller help clean stuck on dust, small and large particles. It seems that the soft roller does do a good job on hard floor cleaning based on many users reviews.

Cord Length
Both have a 30-foot power cord.

Other things you may want to know before buying:
No Suction Control
There is no suction adjuster that allows you to reduce suction when cleaning curtains, area rugs, or delicate things.

No Pile Height Adjustment & No Brushroll On/Off Setting
There is no control to elevate or lower the rollers to fit different piles of carpet.
The only thing you can control is the surface setting. They have 3 settings to choose from:
Thick Carpet/Area Rug, Carpet & Low Pile, Hard Floor.
When cleaning hard floors, the rollers continue to rotate, the only difference between the 3 floor settings is the speed of the rollers. If you want to buy a Shark vacuum that allows you to turn off the brushroll, you can take a look at the Shark Rotator Powered Lift-Away NV750 series.
