The $599 V11 is Dyson's latest and greatest stick vac. It's also the most expensive machine in our test group. That said, this flagship model delivered best-in-class performance to match its steep price. On hardwood surfaces, the V11 literally wiped the floor clean. The vacuum demonstrated near-flawless pickup of both sand and black rice test samples (99.6 and 100%, respectively). 

Pet owners will also appreciate the V11's prowess at eliminating pet hair. During anecdotal tests, the vacuum completely removed hair fibers from mid-pile and low-pile carpets. Pet hair pickup across hardwood flooring went almost as well. The only detractors were a stray clump the vacuum missed at the top of our test area. That and a few strands ended up wrapped around the V11's brush roll. 

I certainly like how easy the V11's dustbin is to empty. Just aim the vacuum into the trash, and push a release tab to open the bin's lid. To close it, pull the tab in the opposite direction. Other models we tested were a nightmare in this regard. The Hoover BladeMax gave us the most trouble. Hair and dust typically became trapped deep inside its dustbin. I found its bin tricky to open too. Worse, it isn't always clear that the bin is securely attached.    

Dyson also bundles numerous attachments in the box. Among them are tools for cleaning crevices, dusting and pulling ground-in dirt from carpeting. All this makes the Dyson V11 the clear choice for the best cordless vacuum money can buy. Read more about the Dyson V11.

The second-best performer in our group of cordless vacuums was the $279 Shark Rocket Pet Pro Cordless. It came very close to cleaning floors as well as the Dyson V11, but costs hundreds less. The Rocket removed just as much sand from both midpile carpets and hardwood surfaces. In fact the only area where the Shark trailed the V11 was over low-pile carpeting. There, the machine pulled away an overage of 67.6% of our test sand. By contrast, the Dyson V11 removed a greater amount of sand from our low-pile carpeting (78.4% on average).

The Rocket didn't have trouble handling pet hair either. On both low-pile carpeting and hardwood, the vacuum wiped away all traces of animal dander. Results were favorable across midpile carpet, too. Only a small tuft of hair remained after the vacuum passed over the thicker, more challenging surface.

Design is another of the Rocket Pet Pro's strengths. Its dustbin is almost as easy to empty as the Dyson V11. The container typically remains clear of dirt and debris as well, not stuck inside even after emptying. I also appreciate how the Rocket Pet Pro's wand attachment can stand upright on its own (disconnected from the main vacuum unit). So, if you seek a solid midrange cordless upright stick vac, Shark's Rocket Pro is an outstanding option.

If you'd like to own a Dyson but would rather not spend top dollar, consider the $449 Dyson V8 Absolute. This step-down model is a few years old, yet still performs like a champ. On our floor-cleaning tests, the V8 came in a respectable third. In our test group, only the Dyson V11 and Shark Rocket Pet Pro scoured floors better than the V8.

On hardwood, the vacuum managed to pickup an average of 98% of the sand we dropped. For low-pile carpets, that average fell to 68.3%. The average slipped further across midpile carpets, though remained at a respectable 52%.

Pet hair didn't faze the V8 much either. It pulled hair away from midpile and low-pile carpets completely. It did fail to remove a small amount of dander on hardwood. Additionally, some fibers became wrapped around the vacuum's brushroll. 

And similar to the V11 Torque Drive, the V8 Absolute comes with a generous assortment of add-ons. That includes gadgets for dusting, reaching into tight crevices, and grabbing ground-in dirt. So for those who'd like to own a Dyson brand stick vac a little less cash, the V8 Absolute is worth a look.      Read more about the Dyson V8.

Moosoo isn't exactly a household name. Nevertheless, the $98 Moosoo M X6 cordless vacuum packs a respectable punch, considering its low price. Despite costing much less than competing vacuums, the M X6 was the fourth-best performer in our test group of eight models.

The stick vac picked up 99% (on average) of our test sand from hardwood. On low-pile carpeting, that figure sank to 41.3%. The M X6 fared better across thicker midpile carpet though, earning a higher sand pickup average of 52.2%.

Black rice, our large particle test soil, was a breeze for the Moosoo vacuum. It managed pickup averages above 90% on hardwood, low-pile and midpile carpet (95.4, 96.8 and 94%, respectively).

Don't buy the Moosoo M X6, though, if you're a pet owner. At least some visible dander remained after vacuuming, no matter the test surface. The brushroll tends to wrap strands of hair around itself as well.

If you want cordless vacuuming on a tight budget, however, consider the Moosoo M X6. It just might fit the bill, and for much less cash.
