Shark Stratos Vacuum Lineup: Upright, Corded Stick, and Cordless Compared

Introduction

The Shark Stratos line launched in late 2022 as a new family of vacuums from Shark. Every model in the range shares a few core traits: strong suction, self-cleaning brush rolls, and specialized tools designed to move pet hair. This lineup includes three flagship versions: the upright, the corded stick, and the cordless stick.

All three vacuums delivered excellent performance across a series of objective, data-driven tests measuring cleaning performance and overall usability. The testing process covered 12 different tests on three types of floors with four different types of debris. Each vacuum ran over the debris on max suction with a single forward and single backward pass.

Cleaning Performance

Cleaning performance across the board was fantastic, with each vacuum scoring over 95 percent for overall debris removal. The Shark Stratos upright outperformed the other two vacuums, but the difference was negligible. All three models did a great job of removing small and large particulates.

The Shark Stratos corded stick did a fantastic job, especially on high-pile carpets, where it removed 99 percent of all debris. It struggled a bit with rice and cereal on hard floors, but these issues can be avoided by making more passes.

The Stratos upright removed 98.3 percent to 99.5 percent of all debris depending on the type of floor. Unlike most vacuums, it did not struggle with cereal and other large particulates. There were some issues cleaning up sugar on high-pile carpets, but everything else went perfectly.

The Stratos cordless is supposed to have the highest suction power of any Shark cordless vacuum, and testing confirmed it did a great job. It performed slightly better than the Shark Stratos corded stick, but it struggled with kitty litter and sugar on high-pile carpets. However, it still removed 100 percent of the rice and cereal spilled on the carpet.

Hair and Pet Hair Handling

To test long hair performance, one gram of long hair was placed on hardwood floor and each vacuum was run over it on the max suction power. The brush roll and the floor were then checked for any remaining strands of hair.

Both the upright and cordless had zero issues with long hair. All of it was removed from the floor and none of it tangled. The corded version was tested with an older version of the long hair test, so exact measurements are not available, but a small amount of hair tangled around the brush roll. It was minimal and easy to remove, but still the worst performer of the three models.

The pet hair test put the Stratos vacuums against 1.0 grams of pet hair on high-pile carpet. The vacuums were run on their max suction setting and the floor was checked after the test for any remaining hair. All three vacuums had no issues with pet hair, completely removing it from the carpet fibers.

The vacuums were also tested for how well they are sealed. A smoke machine was aimed directly at each vacuum, shooting small bursts of smoke into the device while it was running. All three vacuums were completely sealed, not releasing any smoke. Their ability to fully contain smoke indicates that they are also able to fully contain the smallest dust particulates.

Power, Runtime, and Noise

To measure wind speed, an anemometer was placed against the opening of the tube connecting to the vacuum. Each vacuum was run on each mode and the miles per hour of inward suction was measured. Surprisingly, the cordless stick had the highest wind speed on the highest suction setting at 19.5 miles per hour. The upright and corded stick had lower wind speeds, but despite this, still had strong cleaning performances across the board.

Both the Shark Stratos upright and Stratos corded stick must be plugged into an electrical outlet for power, offering endless runtime. The Stratos cordless, on the other hand, can run for over 60 minutes at a time. The cordless was tested in two power modes to see how long the battery would last.

The Eco mode uses the least power, allowing the vacuum to run for approximately 80 minutes. On boost mode, the vacuum has the highest suction and was able to run for 14 minutes. The vacuum also has the Clean Sense IQ mode, which is an auto mode, so runtime varies depending on floor type and how dirty the floors are.

Noise levels for the three devices fell in the 65 to 76 decibel range, with the cordless stick vacuum being the loudest at 75.8 decibels. Noise levels were tested using a sound meter from about three feet away from the device. While the cordless was the loudest, it wasn’t by much. All the vacuums are going to be loud while running, with the stick vacuums being slightly quieter on their Eco modes.

Usability and Maintenance

As far as usability goes, all three vacuums, including the corded versions, are super easy to set up. The primary maintenance tasks include keeping the brush roll clean, washing the filters at least once a month, and emptying the dust bin as needed. The odor-neutralizing cartridges should be replaced twice a year or as needed.

While they are all part of the Stratos line, there are some notable differences between each version. The stick variants can be used in handheld mode, while the upright cannot. That said, the upright’s dust bin can be removed from the device and used more like a canister vacuum. All three versions of the vacuum include headlights for visibility.

The corded stick lacks the multi-flex wand that the upright and cordless versions have. Dust bin capacity also favors the upright, having 1.48 quarts of space available. In comparison, the sticks are about half that size, with the corded having 0.79 quarts and the cordless at 0.72 quarts.

The three vacuums have similar accessories with very similar cleaning heads. The only exception is the Shark Stratos upright with the TruePet upgrade, which includes eight different tools with some cool extras. The Stratos upright has the most attachments that come with the base model of the vacuum, and the TruePet upgrade adds even more.

Which Shark Stratos Is Right for You?

The corded Stratos stick is a great recommendation for people who want the convenience and size of a lighter weight stick model but don’t have to deal with the battery. The corded stick removed 96 percent of all debris and 99 percent on carpets. In addition, if you have pets, the corded stick is a great choice. It removed all of the pet hair on the floor with just two passes. Its brush roll can remove the hair stuck in carpets and upholstery, making it easier to keep your house clean during the shedding season.

The Shark Stratos upright can be a good choice if you want a large dust bin. The dust bin on this vacuum can hold up to 1.48 quarts of debris. Therefore, the Stratos upright is recommended for people living in bigger homes or those who just have a lot of cleaning to do. Additionally, it has superior cleaning performance. The upright removed 98.9 percent of debris in testing, plus 100 percent of all pet hair. Moreover, it did a great job on all three floor types. Lastly, it has a large selection of accessories. It includes a larger number of tools than the other two models. The TruePet upgrade version comes with three cleaning heads, a crevice tool, an upholstery tool, and a flexible one.

The Shark Stratos cordless is amazing if you want the best usability and most convenience. In addition, it’s incredibly lightweight at just 8.9 pounds, and the flex wand allows for compact storage. Its cleaning performance was just as good as the Stratos corded stick, removing 96.6 percent of all debris by type.

Conclusion

At the end of the day, all three of these Stratos models are incredibly high-performance cleaning machines. Ultimately, it is really hard to go wrong with any of them. The right choice comes down to your priorities: the corded stick for lightweight convenience without battery concerns, the upright for larger homes and maximum dust bin capacity, and the cordless for the best usability and portability.
