Fantastic! Easy on hardwood, great on carpet, easy to clean but not for tight spaces or off the floor.

I want to give it a 4.5 so rather than a 4 I'll give it a 5.  I am comparing this to my Hoover windtunnel and this is amazing.  Very light, easy to maneuver and it sucks...in the good way.

This thing is light and maneuverable.  It has two speeds (for the brush roll) which makes it easy to pick up the kitty litter.  The Hoover, on hard floors if you have the brush on (only one speed) it would propel the kitty litter and toss it around.  Imagine sand blasting but with kitty litter.  If you turned the brush off, it didn't always pick up the sticky litter.  However, the shark does.  Put it on low and it works. I mainly use the high for carpets only.

Also, I believe the shark sucks more evenly across the roll rather than the Hoover that has a suction nozzle on one side. It has two brush rolls, a soft for hard floors and a regular bristle stiffness.  You can use the regular only and you will be fine but if you want to take care and avoid scratching laminate, vinyl and especially hardwood floors then you should use the soft one.  Yes changing brush rolls requires extra work switching back and forth but worth protecting the more "sensitive" floors.  At least switching rolls is a piece of cake but can't actually specify the type of cake at this point.

On the topic of changing brush rolls, the fact that they come off means no more putting the Hoover upside down taking a sharp knife and cutting the long hair that get tangled on the roll.  With the shark just pop it out and pull/slide them off.  Love that!!!  As for suction more than happy. The machine tends to want to run like a self propelling lawn mower which makes moving forward a breeze but makes pulling it backwards slightly more difficult but still easier than my Hoover.

The reason for the minus 0.5 star is that because the whole motor, dust can and so forth are located on the bottom it does does not have the detachable hose with attachment to get into those tight spaces like regular vacuums do.  Also you cannot clean upholsetry or anything off the floor.  This is clearly meant for JUST THE FLOOR.  However, Shark in their commercials make this self evident.  That is where I use my shop vac. I will say that I was expecting this problem so I am not at all dissapointed.  This means that this vacuum cannot completely replace all your other vacuums simply because it cannot get into spaces narrower than the width of the machine.  one last thing is that the dust pan is smaller which means emptying in more frequently.  Understandable since it is more compact.  Again to be expected so not dissapointed.  Lastly, the Hoover has fancy Heppa filters and so forth.  The Shark has simple felt and foam filters but they do the job adequately in my opinion...just something you should know if you are super allergic or something.  However it seems plausible that you can buy similar filters cut them into shape to fit into the Shark.  There is a beauty in the simplicity of the filters.  They are just filters without special holding brackets meaning that you have to buy the "special" filters.  I feel that you can make your own.

So, I love it and I highly highly recommend it but you still need something for tight spaces or anything not on the floor.

I love this vacuum.  It is so lightweight and has powerful suction.  I have about 900 square feet of hardwood flooring and am able to vacuum it all and still have a charge left in the battery. Easy to remove and clean canister.  The only reason I did not give it 5 stars is it does tip over easily.  Seems like it could be designed to be better balanced.  Otherwise, really, really like it.

I have not had it long, but I like the fact that it's not hard to push, like the upright ones are. This kind of vacuum is easier on your back. It's great on hardwood floors and powerful enough for a quick vacuum on the carpet. Maybe not as powerful as my upright for the carpet areas though. I have both. Easy to clean. Only negative -  the long handle part with the beater bar does not stand alone. You need to lean it up on something or lay it down. They need to figure out how to fix that. This is larger than I thought and you need room to store it. There are many attachments. I have not used them yet.

Lightweight, easy to use and so much better than a mop and bucket! My hardwood floors have never been cleaner !

Never owned a stick vac, just the regular full-sized typical types. Needed something to avoid sweeping constantly w/my new wood floors so chose the Hoover Flair.

I like it!

This vac is LIGHTWEIGHT (to me), EASY TO MANAGE, SWIVEL HEAD makes it easy to go under dining chairs and stools, etc, GREAT SUCTION picks up everything nearby! Great for crumbs kind of thing (but doesn't necessarily handle dust layer over whole floor particularly, which requires a dust mop in addition to a vac).

I DO like the option to turn on the brush for the area rug I have under the dining table.

Dust cup is really easy to dislodge and clean. I take it outside (when possible) & use an old toothbrush to brush off old dust, hair, and debris.

I'm babying this so it lasts a good long time. I'm watching for scratches on the floor; so far (about a month of using often) it's fantastic. (I do notice that there's two thin strips of rubber under the head -not part of the brush but on the base-  that's starting to wear already. If this causes scratches in the long run I will be MAD but not sure it will! I also would note that the head/bottom is mostly made of a hard plastic, so if you're hard on your vac and it roughs up that plastic, you might cause scratching! (that's why I'm using this very cautiously and not carelessly ramming it into cabinets or furniture or...anything).

Also DO like that it can stand on its own and doesn't fall (unless I don't make sure it's straight up...then it's really my own fault).

The cord is fine for my purposes as it reaches everywhere I need it to. Any longer and there's that much more to wind up. (The cord holder DOES swivel sideways for easy access to full cord).

Love the red color : )

Only thing I WISH I had was a handheld dustbuster attachment but not sure anything like that is available for electric models. (I'm leery of the cordless models as I do NOT want to spend money on a vac that the battery burns out!)

Overall I think you'll really like this vacuum! I do!

Hope this helps.

It's powerful, versatile, quiet, easy to use and maneuver. It takes a little more muscle to move the head on carpet, but it gets it really clean. It's perfect for our home because we have lots of hardwood floors covered with area rugs and kilims. I can't imagine using it on thick, padded carpet-it would be a bear to move around. For our purpose-hardwood, tile and area rugs-plus 2 dogs, 2 cats and teenagers, it works great.
The bags are a bit small and kind of pricey, which is the only reason I rate it 4 instead of 5 stars. However, they keep a lot of dust out of the air when changing them or vacuuming.

I have tried the first of these amazing rugs a few months ago, they are just fantastic, easy to clean and they stay put where you want them,Now I have an entire collection, and I vaccum them with my Dyson. I have 3 dogs and these rugs just trap all the stuff I do not want on my floors, so it is easy to clean. Great product!

I bought this a bit on impulse at my local department store.  It was on sale (I paid $270) and I was really impressed with how lightweight it was.  Our living room,kitchen, family room, dining room, entry, and guest bath are all hard surface floors.  I have 2 dogs that don't shed much (short-haired dachshunds) but they and my husband track in a lot of dirt and fir needles.  I had been using a Hoover Flair for quick pickups, but it was quite a bit heavier and really hurt my shoulders.  Here's my pros and cons:

Pros:
1) super quiet, my husband loves this
2) very lightweight, much easier on my shoulders than the Flair
3) the dust cup is super easy to empty
4)  the battery is very easy to remove and (although it is pricey) there are replacements readily available on the Dyson website.  This means that if you don't like the wall hanging unit or want to store it in a closet without an outlet you can easily do so and charge the battery elsewhere; if you need longer cleaning time you can have a spare battery; and you're not going to have to landfill the unit in a couple of years when the battery won't charge anymore
5) The suction is good; I'm amazed at how much dirt it picks up
6) I have not yet run the battery all the way down.  Again I am just using it for quick pickups, but over a fairly large area

Cons
1) the lack of an on/off switch.  This is just absurd and an absolute no-go for me due to pain in my hand and wrist (and I bought it in the first place because of pain issues).  I almost returned it because of this, but my husband loved the quiet so much he practically begged me to keep it.  So I sewed a strap with velcro that I can tighten or loosen to turn it on or off.  But really it's silly that I should have to do that.
2) Cost, a lot of money for a vacuum that is somewhat limited in its scope.
3) Don't think it does too well on carpet.  I've only used it a bit on area rugs but it doesn't move as smoothly.  Might not be the unit for you if you have a lot of carpet, but this isn't an issue for me as I bought it for the hard floor areas.

For me the pros far outweigh, I'm really enjoying the super quick, easy cleanups.  A keeper for me.

No surprise here. This is the greatest vacuum I have owned. Excellent suction. I can't believe how dirty the floors were...and we vacuum weekly.  but our old vacuum didn't have great suction and was cumbersome to use and cumbersome with attachments. It's lightweight (for a full size vacuum), incredibly easy to maneuver and the long built-in extension easily cleans one long flight of stairs while the base remains at the bottom. No fussing with attachments. Absolutely love it. My husband even liked it so much that after we put it together, he vacuumed the whole downstairs. Win!

This vacuum is great for wood floors!  It's very nimble as the head of the vacuum is on a swivel - so it's great for getting under and around things.  It's also very, very light.  Works great on our area rugs and wood floors and seems to pick up all of our dog hair very well.  We love this vacuum and think it's a steal!

This is a fantastic vacuum cleaner. It initially feels heavy but it is so easy to use, due to the "swivel-ness". It makes vacuuming so fast and effortless. We have 3 cats and every time I vacuum, even if the rug doesn't look dirty, it picks up a full canister of dirt and cat hair. We did have an initial problem getting the bottom to bend for use - there is no button to push, you really need to almost slam the bottom on the floor to get it to bend for use, but once we figured that out it is a great cleaner.

Definitely work well on carpet. A little too slippery for hardwood.

I love this vacuum. It is small but mighty - easy to store, does a great job on my hardwood floors. The parts fit together very well and do not fall off in the middle of vacuuming. This is the best vacuum for wood floors I've ever owned.

Used it on hardwood flooring and it works fantastic. Very light, durable construction and very easy to use. The only slight downside is the attachment may be a little difficult to remove, so I would probably not use them and just use the large head. The bags are sturdy and filtration is really great. Highly recommend it.

Fabulous. Light and easy to use and maneuver. Does a great job of cleaning our wooden floors - but make sure you vacuum first!

Great vaccum! Really good suction and moves easily from carpet to hardwood. I love that the battery charger is small and separate from the vaccum. I can stick it in a closet and don't have to leave it out near an outlet.

I have hardwood floors, and three cats. Before we got this, it was impossible - even with sweeping every day or so - to get control of the little tumbleweeds of cat hair and dust everywhere. Now, I turn loose this little gem every other day, and the floors stay so much cleaner.

The botvac is bright, but can still get stuck in some situations. Typically, chairs or small tables with legs just a little wider than the botvac can cause it to bump around a lot until it finally gets exactly the right angle needed to escape. If you have very fragile or expensive furniture, keep this in mind. Also if you have sofas, beds, or dressers with floor rugs that extend right to the edge of them, sometimes the botvac can get under the item, but won't be able to get back out. Moving the rug slightly can avoid this usually. (it is very gentle otherwise, on furniture that it can "see" well with it's sensor, it's uncanny how well it navigates and gets right up to every edge far more gently than I can even by hand)

I've got a large, rather oddly laid out first floor, consisting of six rooms, and a lot of odd angles. Impressively, the botvac always finds it's way around. It usually goes back for a charge about halfway through cleaning, and picks up right near where it left off.

There is one pleasant consequence to having one of these items: It encourages you to keep clutter off floors - wires, loose clothing, etc. - allowing a much more complete cleaning and just a nicer-looking home. Win/win, IMO. (we do have a laundry room, which I know is always going to be cluttered, so we have the magnetic tape at the doorway to tell "bender" to leave that room alone. Works fine).

I had been having really bad allergy symptoms for a long time, and they are much less troublesome since turning "bender" loose on the house a few times a week. It is shocking how much dust, hair, random bits of lint, and similar this thing gets. All of that was just sitting around and making all of us feel miserable a lot of the time before.

I would be skeptical of the cleaning ability of one of these on carpeting, but on both hardwood and tile flooring, it does a terrific job getting rid of amazing amounts of dirt. I'm very pleased with the results.

Why didn't I give it five stars? Mostly the high cost. It's a fair value for the price, but not a spectacular value. Other units are worth a look, and you may be able to find one that has 90% of the features for 60% of the cost.
