I bought this a month ago and run it on the 4.0 batteries. My dog was shedding all over the truck and the car, so I figured it made sense to go with this unit for the small jobs I needed it for (sawdust and dog fur). I went in with appropriate expectations because it is a cordless unit, and am very happy with it. Beats the snot out of standard homeowner solutions for cordless cleanup. Run time is enough to clean out the pickup. Pros: portable, stackable, fairly lightweight. Cons: short hose, only the crevice tool is really useful. I would suspect you could get one of the air turbine brush heads for a standard vacuum and modify it for use on the Milwaukee, which might make tasks like pet fur cleanup easier.
