Shark NV771 on Amazon:
https://www.amazon.com/DuoClean-Cleaning-Lift-Away-Anti-Allergy-NV771/dp/B07BFJHZFP/ref=as_li_ss_tl?ie=UTF8&qid=1539205932&sr=8-1&keywords=nv771&linkCode=ll1&tag=cewhitebooks-20&linkId=ce2554abbe965768e5da4d8571c71b6f&language=en_US
So the Nv771 is a “Speed” which is a term Shark uses that means it is a lightweight vacuum and that its brush path width is slightly smaller meaning it can get into places the bigger floor nozzles cant.

I have preferred Shark’s Speed series over the larger vacuums for a while since I value lightweight vacuums and precise maneuverability.

So as I mentioned this is the cheapest upright with Duoclean I have seen, the previous cheapest was the NV200 series which I reviewed and could not recommend because it was made of really cheap materials, and wasn’t even all that inexpensive for what you got.

But with the Nv771 it has a really high build quality, in fact it looks like it was based on the old Rotator lift away series, but with DuoClean.

So Im sure my subscribers are pretty tired of me extolling the virtues of Duoclean technology but lets go through it one more time.

So Duoclean floor nozzles have a soft roller up front which makes it literally unparalleled for hard floor performance. Picking up everything it touches from pet hair to extra large debris, its ironically also amazing for super fine debris, basically dusting the floors as it picks stuff up.

But the standard brush roll behind the soft roller is there to agitate carpets as well, and so Duoclean vacuums have the same great performance on carpet with pet hair and debris of all sizes, but it also can deep clean carpets really well.

On the Nv771 you just flip a switch on the housing to change from hard floors to carpets which changes the speed of the brushroll so transitions are very easy.

All that to say that Duoclean vacuums are by far our favorite type of vacuum and they are what we use in our cleaning business.

Some of the other features include bright LED lights on the floorhead which are more usefull than you might think.

The wand is one of the easiest to remove and use in the business, It also has the Lift away feature meaning you can detach the canister for a super lightweight way to use the attachments. Keep in mind this is not a powered lift away meaning you cannot attach the wand directly to the floorhead like you can with the more high end Shark powered lift aways. This limitation is, as I can tell, the main thing you sacrifice by getting the less expensive Nv771 as opposed to the Powered Lift Away Speed Nv800 series. .

That being said the main reason I use the Powered lift away feature, like with my Apex is because it reduces the weight, but with the NV771 Speed, it only weighs 13 lbs anyway which is ultra light so it really isn’t even necessary.

Like most Shark uprights the Lift Away Speed is a sealed System with HEPA filtration, as we saw in out 5 micron fog test, which is pretty rare for a vacuum in this price range.

We measured its suction at about 77 inches, and its airflow at 74 cfm at the hose and 58 cfm at the cleaner head, which is amazing for a vacuum in this price range, for context compare that to the Dyson Ball Animal 2 or the Miele U1 which are far more expensive vacuums.

Shark also has an amazing seal on the floor nozzle, as seen by picking up all the debris in one half of one pass which is an extremely rare feat.

Like most Sharks the dust bin has an open layout which is easy to keep clean to preserve its power over a long period of time, its easy to empty, and bigger than other speeds I have seen.

As far as attachments, it comes with a crevice tool slash dusting brush, and an upholstery tool slash dusting brush.

The only real cons are that I wish the hose was on a swivel at the base to keep from twisting, but since it picks up everything anyway I don’t actually use it that much.

I also wish it came with a few more attachment options but I assume that is one way they are keeping the cost down with this model so I can live with it.

So I think this is the first budget Duoclean upright from Shark that I can fully endorse I love the Duoclean technology, and the sealed system, it has a lot of power and its got a much better build quality that previous budget vacuums.

    My Dyson was actually picking up fibers from my oriental rug. How does this one treat rugs. Is there an ideal cfm or brush configuration for getting a good clean without damaging? Thanks!

    Thank you for this! I've been searching the internet to figure out what vacuum to buy. I'm between this one and the Apex, although the lower price point of this one is appealing. I have cats and they shed like crazy. I want something that will be able to stand up against that. We have hardwood as well. The cat hair is mostly short. Do you have an opinion between the two?

    Hi. We have 2 dogs with long and short hair lengths. My daughter and I also have long hair. Would you recommend this vacuum with our hair types ha ha!? We also have hardwood floors and chiseled tile in our kitchen. Thanks.

    Could you please Test Bosch Unlimited Cordless vacuum cleaner BBS1… or BCS1… they are basically the same as far as I know the only difference are the accessories.

    I wish the non powered lift away models could still attach to the floor nozzle. I like being able to put the floor head on the hose to get under tables and couches (i have the original navigator lift away, and i hate it, but that feature is very convenient)

    Wow, that is cheap! I agree about the benefit of the narrower cleaning path and light weight. My favorite vacuum (besides my V8) is a Tacony Supralight. It’s less than 10 pounds, has a narrow cleaning path and kicks a§§ in cleaning ability. I had the fancy Tacony with dual fans and it was too big and clumsy. So hats off to your new fav!
