Question: How does it perform on hardwood floors?
Document: It's great on our hardwood floors, too! It really does have a ton of suction!
Oh, it does a fantastic job on hardwood floors as well and did come with nice attachments.
Recommend this for anyone who has pets, especially golden retrievers like us! Does a fabulous job on both carpets and hardwood floors.
Arrived quickly and is working great. For being a recon unit, it appears brand new. Assembly was easy. Great for both carpet and hardwood floors.
No problems. It pulled dirt out of my carpet that the vacuum it replaced missed. I can also clean my hardwood floors with ease. One of my best purchases in the last year.
I'm a guy...and this was just what I needed. Picks up everything from molecules to mastadons--and adjustable to every surface from hardwood floors to deep pile carpets. I was a bit nervous about a reconditioned item, but they check everything and it's better than new!
I am very conflicted on this product, it works very well on the carpeted areas of my home but most of my home has hardwood floors and this vacuume is designed for carpet and bare floors it is scratching the hell out of my bare hardwood floors and obviously I cannot tolerate this, what a shame too because aside from that major problem it's an awesome machine.
We have several furry kids so wanted a vacuum that would last. I have had this for a couple of years now and it still works like new. I love all the attachments. We had our previous Dyson for 5 years and my children sucked up water with it and I had to replace it after that. I have carpet and hardwood floors in my house and it works great for both!
This product is NOT good for hardwood OR hard surface. This product SCRATCHED our BRAND NEW floors. They will require refinishing and replacement of tiles. DO NOT BUY THIS IF YOU INTEND TO USE IT ON HARD SURFACES. Also, it is NOT good on thick pile carpet. It will NOT move. Very very disappointed and disgruntled.
This is my 3rd Dyson. I have a white lab and the vacuum works great at picking up dog hair both on hardwood surfaces and carpet.
Answer: Just like with most vacuums, it  kicks the dirt back at our feet.  Vacuum bare foot and you'll feel the particles hitting your feet.  I have found that the only vacuum that doesn't do this is my canister vac and that's because it has a hard floor setting.
