Excellent vacuum with great suction for a cordless vac. I have a Shark Rotator corded as my regular vacuum and it is a cleaning beast. It can suck a bowling ball through a garden hose. I was not expecting a cordless vac to have as much suction as a corded model, but this one does not disappoint. Having just returned a Tineco cordless vacuum for lack of suction and overheating issues, I really appreciated this one. The suction is good, the Duo Clean rollers grab every speck of dirt (except by the edges) and does a great job on everyday pick ups, which is what I bought it for. I don't understand the bad reviews over battery life. I have vacuumed my entire 1200 sq ft apartment with battery life to spare. I have birds and they are VERY messy. I vacuum up bird food the size of dry dog and cat food 3 times a day and have yet to need to do a second pass to pick any of it up. Not to mention copious amounts of bird dust and feather down. The dust cup has adequate capacity and is easy to clean. This Ion Flex is perfect for daily pick ups and was exactly what I was looking for. I love the flex wand that slides under furniture and cages and it folds nicely for storage. I was considering a Dyson V8 Animal but did not like the permanent battery because all Lithium ion Batteries have a lifespan and I would hate to get rid of a $500 vacuum cleaner when it needs a new battery when I can just buy a replacement battery in a couple of years. I purchased this model with 2 batteries, but one does the job on my tile floors and low - medium pile carpets. I love the brush roller cleaning garage with the slot for cutting hair off the roller. What a joy! Rarely have I been so impressed by a vacuum cleaner and both my Sharks exceeded my expectations. I love that the attachments fit both my shark vacuums interchangeably. I wasn't expecting that. Had I known, I would have gotten the cheaper model without attachments. Although this one comes with the allergy duster tool I didn't have. Live and learn. I vacuum 3 times per day and have yet to run the battery down completely. It doesn't have the suction of my large corded vac, but I save the big guns (the Rotator) for the big weekend clean. The cord is a huge pain in the butt so this fits my daily cleaning needs perfectly. And no, I am NOT a clean freak. I just walk barefoot all the time and hate having my feet impaled by bird food and splintered shards from chewed up wood toys. I will report back on this vacuum if I run into any issues down the line. So far I have only used for a week (21 times) and couldn't be happier about this purchase. It cleans like a champ!
+++UPDATE++++
After a month of using this vacuum 3 times per day. I love it more and more. I haven't used my corded vac in over 2 weeks.
4 Month Update!
I would marry this thing! Best purchase EVER!

Pet owners beware
This vacuum is strong and very effective. It does great work. In fact, I now cringe to think how poorly our old vacuum was working and, thus, how dirty the rugs were. I have now had it for about 2 months. I would look into returning it but we are beyond the 30 days. What will I do? Buy a Miele and use this one for the quick jobs. Now for the issues:The rating is a 3 primarily because we have a golden retriever and it is not optimal for longer fur animals though I think it would be fine for short hair dogs. The fur has gotten trapped in the small wheels that are adjacent to the silver roller with the orange bristles and has jammed them. This happened after one of the first times we used it. See photo. We had to pry the fur out of them since there appears to be no way to remove this fixed roller for access. Consequently, we are unable to completely clean it. The fur has also matted in the narrow space between the 2 rollers. So what have I learned? This vacuum requires LOTS of cleaning and I now vacuum 3 times a week so the vacuum does not have to deal with too much fur and because the house needs it! Our house is 1600 sq ft. We have 2 rugs: both low pile and hardwood or tile everywhere else. I empty the bin 3 times and clean the rollers at the same time. The second empty comes after the dining room rug and the entry hall runner as these are the fur catchers. I find this high maintenance. I also happen to have long hair and it gets wrapped around the silver roller and I use a scissors to cut through it to ensure this roller is cleaned thoroughly of hair and fur each time I empty the bin. The roller does have 2 grooves that I use to guide the scissors, so thanks for that. The other filters get cleaned once a week. Bottom line, it is a pain in the kazoo to clean.So, many of you may think I did not think this purchase through. Well, maybe not, but I do not recall anyone mentioning the amount of cleaning the vacuum would require. Cordless and the 2 batteries were very appealing. Again, the vacuum is good. It is just really high maintenance if you have a pet with long fur.Two other negatives for me:1. The vacuum is heavy in my hand. My hand and wrist are done by the time I complete the job. I am used to a wand and canister.2. The accessories are cheesy.
