Used product for less than 60 days and it's dead
Ordered this vacuum on January 31. I was vacuuming an area rug and it stopped working on March 31. 60 days of product use and already a break down leaves me less than impressed.

powerful but heavy!
I bought this about a year and some ago. This thing is powerful and quality however, the one major con is how heavy it is. I don't have very good wrists, so I am giving this away. Also terrible with stairs. When you want to use this as a "stick" vac, beware that it is bulky and you will have to deal with holding and moving the canister with you almost every step of the ...

Overheats in 10 minutes
This machine is a great design but I can't recommend it. Every time I use it, it overheats after just one room. I have to wait for it to cool down before I can continue. It's going to take 2 hours to fully vacuum at this rate. I love these products. They are usually thoughtfully designed. This one has to go back.

Hi there,

We’re unhappy to hear that this vacuum hasn’t met your expectations, especially since you’ve trusted our Shark and Ninja products in the past. We understand how difficult it can be to use a vacuum that feels hard to maneuver and the way the vacuum reacts to certain rugs and flooring. Your feedback about the strong suction, button placement, and the experience on thin washable rugs is incredibly valuable. This isn’t the ease and convenience we want for our customers, and we’d really like the opportunity to look into this further for you.

Pops Breakers
I bought this about a month ago and the suction is great; However, it pops breakers all over the house. I can only use it in a couple of areas. I previously had a Shark vacuum that was not a Powerdetect and never had any issues. The first troubleshooting item is about this problem, so it’s obviously an issue.
