    Convenient, but not a corded vac.

    This vacuum surpassed my initial thoughts and is a great fit for my studio apartment. It's definitely not as powerful as the corded shark counterpart, but that was expected. 2x the batteries makes life easier and don't get this vacuum if you have a thick rug! Stick with corded.

    We couldn’t be happier with this vaccuum! We wondered if one battery would hold up for a full run through of the entire house and it totally does! No regrets in this purchase and we even already recommended it to so many of our friends.

    This is the best vacuum ever. This is the second one I have purchased. I love mine and bought this one for my grandmother and she raves about it and tells me everyday a new thing she has descovered it helps her with. Amazing purchase.

    This vacuum is easy to manuver and lays flay for vacuuming under furniture. If I had to criticize anything it would be that the top where the handle and controls are is a little heavy. It is easy to empty. I would buy it again.

    I have always wanted a vacuum that could be pushed or hold in your hand for smaller jobs and this does the trick. I really like it because it helps get all the dog hair durning the week so when I use the big vacuum I go through less bags!

    Another great product form Shark. I have a 3000sqft home with no carpet. It works great for this application. The two batteries are invaluable. Allows me to do the entire house! Also does the area rugs very well too!

    This vacuum is powerful and satisfyingly convenient to use! Get this model as it brings a back-up battery, and you’re going to need to change out batteries after ~20 minutes of cleaning. This vacuum is worth it though.

    Not only is this vacuum a space saver with its small size (which is also foldable), but not having to use a cord anymore cuts my vacuum time in half! Comes with 2 batteries that both hold ample charge.

    Needed a good hard flooring (wood) sweeper vac, and this is this best we have ever bought. Bonus: it's good on carpets, too. Dual batteries make my 2000 sq foot home a breeze to freshen up anytime.

    Easy to change the battery to continue cleaning. The working time with each load is not much in reality, but with the extra battery this is doubled. This should have a dock station to order the accessories.

    Lightweight vacuum with lots of suction

    I was impressed by the IONFlex DuoClean IF251. It comes packed with a lot of power in a relatively compact and portable form factor. The cordless vacuum unit itself is pretty light and has a decent canister size. The IONFlex 2x portion of the name refers to the two battery packs included with this unit, which is a big plus for a cordless device. The batteries can be charged directly from a power cord while in or out of the vacuum as well as in the included charging dock. The vacuum head comes with two brushes and LED head lights to help see whats on the floor ahead of you or under furniture. The vacuum head comes with two brushes, a soft roller on the front and a brush roll. The main wand attachment that connects the vacuum and brushes is flexible as well. It folds over so you can store the vacuum upright as well as to help bend it under low furniture. Out of the box, it comes with several attachments. There is a pet multi-tool with removable bristles that can be used for cleaning furniture and upholstery. There is also an anti-allergen dust brush and crevice tool with removable brush. Performance: I was able to test out this vacuum across a variety of surfaces. It performed well in each case. When switched into the carpet setting, the brush rolls spin faster, and you can feel the vacuum pull forward when moving it back and forth. The regular extended runtime setting does well at removing pet hair from carpets, but there is also a more powerful “Max Power” setting that increases the brush speed and suction for deep cleaning at the expense of battery life. If you need to reach under furniture, you can press the button on the wand that allows the wand to bend and stretch out flat. On non-carpeted floors or movable area rugs, you can switch the vacuum into the floor setting to slow the speed of the rollers. It did well at removing debris from the floor and under cabinet overhangs. On furniture and upholstery, the pet multi-tool attached directly to the vacuum did well at removing pet hair and crumbs. I also used the handheld vacuum and attachments to clean out my car. It did well at removing pet hair and cleaning the seats and carpets. The crevice tool was helpful in cleaning between seats and hard to reach areas. You will probably find that you need to empty the canister several times in the course of charge, as it is moderately sized to keep the device size and weight down. Fortunately doing so is as easy as pressing a button over a trash can to release a hinged door. If you have a dog like me, you may find you have to pull some pet hair out of the canister that wraps around the filter. Battery Life: I charged one of the batteries completely and ran the vacuum throughout my house. With a mixture of carpeted and hardwood areas on the regular setting, the battery lasted about 18 minutes. So, with 2 fully charged batteries, you can vacuum for over half an hour on normal settings without needing a charge. Depending on how frequently you vacuum and the size of your house, this may be sufficient for you. Care: This vacuum was built to be cleaned and maintained. You can remove the cover over the brush roll to get access and remove strings and hair. The soft roller on the front is removable for cleaning. On the vacuum itself, there are three filters that can be removed to be cleaned with water. You can also wipe out the plastic canister pretty easily. All in all, this vacuum is built to be cared for and kept for a long time.
