I had to return the first one but I am unsure if it was defective. It cleaned fine the first night then it would only turn on three seconds after that. I bought a brand new Dewalt battery and charge pack so I returned it for a new one. The new one works flawless and I wanted to give it another chance so had it replaced. I dont think my battery seated into it right after many tries. As i said though the new one works great..great suction perfect for the small room I live in to clean up the rug and laminated flooring. Glad I gave it a second shot it was worth it. Other vacuums are like 150 bucks and most are corded. This is a good deal and built by a dewalt sister company..thats why people buy it thinking its dewalt..basically it is just a cheaper version..and does what I need it to do without paying 150 for the vacuum and 75 for the battery and charger.Mind you this does NOT come with a battery as I failed to read it properly. I had to order the battery after the fact ,but It is still worth the money and works great. Just thought I would clarify that before peoplebought it. Yes i would buy it again..since I got the new one a month ago been using it to vaccuum the car..the couches and everything else does a better job than most full vaccuums ive had in my life lol :POne last verification. It has to use Dewalt batteries it says in the instructions. Dont have any other batteries to test that). So if you have one that’s 20 volt your set. As I said it is a sister company so only Dewalt batteries work (best of my understanding). [...]
