Shark Rocket Corded ZS351 Vacuum with Zero-M REVIEW

So jumping into the pros I really like the Zero M brushroll which is a newly designed system that is supposed to greatly reduce the amount of pet hair tangles on the brush. These little protursions on the top of the housing actively remove any tangles over time. We tried to get pet hair tangled in the brush with our tests and the feature does seem to work well, and many reviews I have seen tend to agree.

Its also really good at carpet cleaning, it picked up all the debris in the tests from fine debris to pet hair and even extra large debris with few issues. It did struggle a little with the froot loops but it was able to pick them up too.

And with the carpet deep clean test, where we rub sand into a thick medium pile carpet and weigh the dust bin before and after it scored a perfect 100% which is not as common as you might think, especially with stick vacuums. It also did good with the thick carpet in this test not bogging down like some vacuums tend to do.

On hard floors it was mostly a pro, it picked up heavy debris like sand perfectly which is somewhat rare, it does have a nice airflow seal on the bottom which Shark has been implementing a lot lately which helps with this. It picked up pet hair very nicely and it did fairly well with large debris to a point. Like most non duoclean Sharks the upper limit was particularly large cheerios and certainly anything larger at least on hard floors.

It was fairly versatile as you can use it as a handheld with the included upholstery tool or crevice tool, its very adept at getting into hard to reach places with is slim design and very smooth swivel. It has two power options, one for hard floors and one where it spins the brush faster for carpets and thick rugs, though the actual power output does not change when you change modes.

We might as well talk about the power now even though its not necessarily a pro.
We measured the airflow at both the base and at the cleaner head and found that it had 45 cfm and 40 cfm respectively, and its suction was measured at about 49 inches of water lift.

The airflow numbers are about on par with a high end cordless vacuum like the Dyson V8 or the Shark Ion P50, though its suction is a bit lower than average in that case, but I do expect more from a corded vacuums like the Rocket is, as compared to its corded counterparts it would be considered below average. That being said because of its mechanics and the aforementioned seal, it does perform like a more powerful vacuum getting a slightly above average score on the crevice pickup test for example.
