Ridgid 18 volt cordless vacuum - it's great!
I hesitated for weeks before buying this thing, it's a bit spendy at $170 (without battery or charger), but I'm glad I finally pulled the trigger. I had a job where I had to use a vacuum up on a ladder and the plug-in vacuums just weren't working out so I finally had a strong incentive to go ahead and buy it.
It's light weight and seems to be as powerful as Ridgid's plug-in model. Without a cord to drag around it is just so damn handy and easy to use it is our go-to vacuum anymore. It uses the same 18 volt battery as my Ridgid drills, which is super handy. Battery lasts about 20 minutes.
The biggest problem is MrsWD has commandeered it for the house and I never know where it is.
