Dreame Z30 vs Shark Stratos Cordless
Quick take: The Dreame Z30 runs longer per charge (90 vs 60 min).
Which one to buy
Four pounds and three years of warranty separate these $300 sticks. The Dreame Z30 weighs 4.9 lbs and owners call it comfortable to wave around. The Shark Stratos weighs 8.9 lbs, and owners coming from lighter sticks notice it right away on stairs and above-floor work. In return, the Shark carries a 5-year warranty against the Dreame's 2 years, from a brand with a deeper US service network.
Both are carpet-capable, which is unusual at this price. Stratos owners rave about the DuoClean PowerFins HairPro head: multi-pet households say it keeps up on carpet without hair wrap, and switchers from older cordless Dysons say it pulls debris those left behind. Z30 owners and testers report short- and medium-pile carpet results that edged out a Dyson flagship, and its 310 AW rating is the headline. Shark doesn't publish a suction figure, so the two can't be compared on paper.
Battery is the weak spot on both, in different ways. The Z30's 90-minute rating is an Eco figure, and Turbo for long-pile carpet drains it fast. Stratos owners call runtime the number one complaint: auto-boost on carpet can cut real use to 15 to 30 minutes, and a known quirk can leave it stuck in high power. Both batteries are removable, so a spare fixes either. Stratos owners also mention a small bin that puffs dust, no battery percentage readout, and clogs at the bending wand joint, though they like that the wand reaches under couches and the vacuum stands on its own.
For heavy carpet, pets and a long warranty, buy the Stratos. For a lighter stick that handles mixed floors well, buy the Z30.

Dreame Z30 vs Shark Stratos Cordless: common questions
Which is better on carpet, the Dreame Z30 or the Shark Stratos?▾
Both do well. Stratos owners call its PowerFins head the reason they bought it, especially in multi-pet homes. Z30 testing found short- and medium-pile results that edged out a Dyson flagship, though long pile needs its battery-hungry Turbo mode.
Is the Shark Stratos too heavy?▾
It's 8.9 lbs against the Z30's 4.9 lbs. Stratos owners say floor cleaning feels fine because the weight rides on the head, but stairs and handheld work are noticeably more tiring.
How long do the batteries really last?▾
Less than the ratings on both. Stratos owners report 15 to 30 minutes with auto-boost on carpet, and Z30 owners say Turbo drains it quickly. Both batteries are removable, so a spare is the standard fix for larger homes.
