    This is our third cordless vacuum, the others being a Dyson V7 and Hoover bag less upright. Ours floors are tile and laminate with a couple area rugs and a few runners and throws so I won’t be judging this on deeper pile carpets. I noticed it’s heavier than the Dyson, but it also has more options and is closer to a regular upright in use. My wife really doesn’t care for the weight and said it’s a little heavy and bulky for her tastes, but would use it without much problem otherwise. It comes with two batteries and I like all the charging options this gives you, either by the charging dock or by plugging in the battery directly into the power cord either attached to the vacuum or not. It also came with plenty of attachments, dual mode furniture brush, crevice / brush attachment, long dusting brush. All of these are nice to have and no need to purchase any other attachments. The brush on this is different than what I’ve seen on other vacuums, it’s a brush and soft roller combination. I was worried about hair getting caught up in the front roller but noticed there’s a row of teeth that push into the roller to cut/clean things that would get wrapped around it. There’s an access door on the top of the power head that opens and you can easily remove the soft roller to wash and clean, only takes a few seconds to get it out, the brush roller looks to be permanently attached. The maintenance door also makes it extremely easy to clean and clear the power head. When using, this feels self-propelled, especially across carpet/throws, when in carpet mode, almost too much for my wife as pulling it backwards is a little bit of work, “good for me though :) “ . When in bare floor mode the pulling is barely noticeable, just enough to help. The headlight LEDs are a huge welcome, in this day of low power LEDs there’s no reason they aren’t included in all vacuums. Makes seeing the dirt you are going after so much easier, and just how dirty your floors are too :O . The center of the main shaft has a latch that you can press to bend the tube in half, this makes it so easy to get under our king sized bed. And with us having a dog that sheds a lot that’s an area that collects a lot of hair. I found myself using this quite often to get under chairs, coffee tables, desks easily. Converting it to a hand vac couldn’t be simpler, and it works extremely well at that with the crevice attachment installed. You can also plug the power head directly into the main unit without the tube attached “haven’t tried that yet”, but can see where that would work extremely well for cleaning carpeted stairs. I was able to get about 12 minutes of run time out of the battery, “it hasn’t been conditioned yet as instructions say to do” so that may increase. I used a combination of carpet and bare floor settings, plus high power “just long enough to see the difference”. So with two batteries I could probably get close to 30 minutes of run time easily, which is plenty to go over the floors in our 1800sqft house. The filters are extremely easy to get to and fortunately are all washable, which is a big plus. I would be nice if they all came with an extra set so you could wash one set and keep cleaning instead of waiting for them to dry out. I'll be ordering an extra set right away. The main complaints I have are, the power button and mode buttons are all right together, and I found myself accidentally hitting the power button when switching modes quite often. I’m sure I’ll get used to it but wish there was a different setup for that. The dust bin is a little on the small size but it’s easy to empty, and found myself having to empty it half way through cleaning the house. In all though this is a really good choice if you are looking for a cordless vac that has the power of an upright cordless. It works just as good as the other vacuums, maybe a little better at picking up fine dirt than the other two.

    When I first bought this it was wonderful but seems like it gets clogged more then my old vacuum though it does suck up more then my old one. Had to have a part replaced this after a bit and the customer service was great they even over nighted the part for free. It fixed that problem but still not sure if this vacuum is worth the price.

    No, I would not recommend this to a friend

    I was hesitant to purchase this since it was pricier than our $99 Shark, but it is worth the difference. The front pad and the overall upgrades really get the hardwoods and tile clean compared to the brush only model we had before. It's cheaper than the Dysons and does the trick, plus it has two batteries which is nice since they do tend to die over time.

    Best Handheld/Stick I have Used

    It doesn't matter if the handheld/stick is corded or cordless, this vac is the best of the ones I have used. The fact it is cordless is all the more impressive. The vac comes with two removable rechargeable batteries and a charging base. The batteries can be charged without the base. Battery life, since they are new batteries this is just the initial impressions, is fantastic. I have been able to go thru the house on a quick sweep (see what I did there?) using only one battery. I am pretty confident as the batteries wear in I will still have the juice to do a quick sweep of the entire house. There are two vac settings on the unit, one for extended battery and one for major suckage. You also have brush control, on and off. The vac pulls the head along so it almost feels self propelled. Weight is about perfectly balanced. Unlike some vacs that can not stand on their own without tipping, this one will stand upright and not tip easily. There is a flex point with button release that is handy for storage but doubles as easier access under tables and chairs. There are a handful of attachment brushes that should get you through any handheld cleaning you can think of. One attachment is perfect for cleaning ceiling fans. A nice addition to the normal brush/wand assortment. Once again, Shark has taken a bite out of the competition. Puns that suck are now over.

    Great little vacuum, easy to use, easy to set up, last long enough on one battery to do my small ranch style house, easy to clean the filters occasionally. If I had one gripe, wish the dirt container was a little bit bigger, but oh well, can’t have everything. Vacuum more often now than I ever have, so easy to just pick it up and go.
