I used to lug around a heavy Hoover and battle changing the bag every time it got full. Then I discovered the Shark Navigator Lift-Away! It was lightweight and compact. I now store my Shark vacuum cleaner in my tiny little broom closet. Because it is an upright vacuum, I save alot of space. And it comes with a see through canister that I can easily detach to empty out as necessary. It also comes with several attachments and a brush so I can get to high places, dark places, corners and anything in between. The cord is also long enough so I dont have to worry about plugging and replugging it into a new socket.The vacuum hums quietly but has excellent suction power even on my old carpeting. For $165, this purchase was a great investment.
