Which is better for pet hair?

The Dreame Z30. It has 310 AW of suction, a built-in pet deshedding tool, and a motorized mini-brush. The Greenworks tops out near 170 AW and ships without a pet tool.

Which is better for car interiors?

The Greenworks 24V. It weighs 5.1 lbs, lists car interior as a top use case, and includes attachments for tight spaces. The Z30 is heavier and built around floor cleaning.

How long does each run on a charge?

The Greenworks runs up to 45 minutes and recharges in about 30 minutes. The Z30 runs up to 90 minutes in eco mode but takes about 4 hours to charge.

Is the Dreame Z30 worth the extra money?

If you have carpet or pets, yes. You get roughly double the suction and double the runtime. If you mostly clean hard floors and cars, the Greenworks covers it for less.

Can I buy a spare battery for either one?

The Greenworks uses a removable 4Ah 21700 pack, and its battery doubles as a power bank. Dreame does not appear to stock a replacement battery for the Z30, so plan on charging in place.

The Greenworks does not publish a noise figure. The Z30 is rated at 84 dB, which is loud enough to drown out conversation.

Greenworks 24V Stick Vacuum vs Dreame Z30 Cordless Stick Vacuum

Buy the Dreame Z30 if you have pets, mostly carpet, or a large home. Its 310 AW suction and 90-minute eco runtime beat the Greenworks on deep cleaning. Buy the Greenworks 24V if you want a light 5.1 lb stick for hard floors and car interiors, and you value a 30-minute charge and a battery that doubles as a USB-C power bank. The Greenworks was $129.99 at Walmart as of October 28, 2026; no current price was given for the Z30, so check its live price before deciding.
