    Great for quick jobs around the house. Better than the Dyson at a lower price point. Battery life is solid, and it includes a second battery!

    Love the fact that you can keep an extra battery charged up. Like others like it, it cannot stand on its own, but it folds down then stands on its own

    Great lightweight vacuum. Works very well on both hardwood and carpeted floors, as well as upholstery. Easy to switch from floors to carpeting.

    Purchased this for my daughter to use for picking up dog hair. Battery life wasn’t an issue but we were glad to get two batteries.

    What this isnt is a replacement for your regular vac for some people. I wanted to get that out of the way. I have several pets and like to have a quick clean nightly and this is excellent for that. After getting the vac i quickly and easily put the unit together and within 10 minutes i was up and running. It lightweight, picks up well and the canister holds a decent amount. It comes with two batteries so you will always have a charged vac.Also it fold in half for easy storage. The controls on the handle are also great, its a touch button to choose from wood floors and other low areas to thicker carpet. You can also control the speed/suction of the vac. It also bends to make getting under furniture a breeze. Im really impressed with this and its a great addition to my home. Makes keeping my place fresh and clean a lot easier

    Always on the hunt for doing things better yet easier and faster, the opportunity to try out the Shark - IONFlex DuoClean IF251 was a welcome experience. Wait. I'm naturally lazy when it comes to housework and want cleaning to go quickly easily and efficiently. This thing better work! There, that's more like it. In all seriousness, this is a very capable and compact vacuum cleaner; being cordless is a definite plus. In Rug Mode the cleaner basically propels itself forward [I literally had to hold it back] and, due to the pivoting arm, is easy to steer. The low profile makes it a snap to get under furniture that has a low clearance and the swinging arm allows easy access under furniture with a taller clearance height. My cleaning cycles have never outlasted a battery charge; having 2 batteries guarantees I'll rarely if ever have to quit vacuuming while a battery recharges. The only downsides are that the dust bin is small and the cleaning width is roughly 8 inches making for more required passes to clean a given area more than with a wider vacuum. The small dirt bin means frequent emptying and the brushes and filters must be maintained more often than my full-sized vac [although main brush has a crevice that makes it easy to cut wrapped up hair fibers for removal]. Shark designers did a good job of making the brushes, bin and filters very easy to access and replace. Whether on carpet, rug or bare flooring, a single pass picked up any material [pet hair, food crumbs, dirt tracked in from outside, etc. in its path. Speaking of which, the headlight is bright and focused and lights the cleaning path handily. For storage, the top section folds forward to make a compact unit that is easy to put out of the way. I find Shark products to be well thought out and built. No exception here; this vac does a great job [the included attachments are helpful] and a great value.
