Dreame Z30 vs Dreame R20
Quick take: The Dreame R20 costs $120 less.
Which one to buy
The extra $120 for the Z30 buys one thing above all: carpet. Both Dreame sticks share a 0.6 L bin, a 90-minute Eco rating, dirt sensors that boost power on their own, dust-revealing lights and a 2-year warranty. The Z30, at $300, is rated at 310 AW against the R20's 190 AW, and that gap shows up exactly where the R20 struggles.
R20 owners say plainly that it leaves a meaningful amount of hair behind on medium-pile carpet and thick rugs, and reviewers warn carpeted pet homes away from it. Z30 owners and testers report the opposite: short- and medium-pile carpet results that edged out a Dyson flagship in head-to-head use, and a pet deshedding tool in the box. Long-pile carpet still needs the Z30's Turbo mode, which drains the battery fast, and owners say it won't deep-clean a large home on one charge at high power. Its battery is removable, though, so a spare solves that.
On hard floors the R20 is hard to beat for $180. Owners report finishing whole houses on one charge in auto mode, praise its soft roller on pet hair, and like that it's lighter, 3.75 lbs against 4.9. Its complaints are a whiny motor, an over-sensitive trigger with no true low mode, a bin that needs a shake to empty, and a roughly four-hour recharge. Owners of both note Dreame's thinner US parts and service network.
Buy the R20 for a mostly hard-floor home and keep the $120.
