What this page compares
A high-spec challenger with plenty of accessories meets the established premium benchmark for mixed floors.
This one comes down to peak suction claim and maximum runtime claim first, then to the limits of your own setup.
Day to day
How each one fits your routine
A box full of accessories needs a task-by-task check
The wider tool kit from Dreame helps only if its supplied attachments fit the sofa, stairs or car you plan to clean. If furniture comes first, find the small powered brush in the exact Z30 box and confirm the compact tool in the selected V15 bundle as well. Go with the attachment set you have confirmed is useful, and do not treat 310 versus 240 air watts as an upholstery result.
Where this comes from
Maximum suction is measured under a given operating condition, whereas lifting fur out of fabric also depends on tool contact and the material. Neither headline establishes a measured winner for your couch.
In the bin, V15 has more room for bulky fur
When bulky loose fur piles up far from a trash can, the selected V15 Detect's 0.77-liter bin offers more nominal onboard space than Z30's 0.6-liter bin. Dyson fits if emptying by hand less often during one session in a distant room is important. Dreame fits if the attachment kit is more useful to you and a mid-session empty is acceptable. Neither model turns that bin capacity into automatic disposal.
Where this comes from
The gap is 0.17 liter, or about 28 percent measured against Z30. Fur density and packing vary, so the calculation cannot predict how many rooms you can do or the exact interval between empties.

Spec by spec
Where they really differ
| Spec | Dreame Z30 | Dyson V15 Detect | In practice |
|---|---|---|---|
| Peak suction claim | 310 air watts | 240 air watts | Higher published output is useful only if your room, surface or workload calls for the extra headroom. It does not, by itself, prove better results. |
| Maximum runtime claim | Up to 90 minutes | Up to 60 minutes | It decides how much you can get done in one session before you have to recharge or swap batteries. |
| Accessory strategy | Large multi-tool kit | Tighter core tool set | Choose working parts that suit your material and your task. A component's name is no proof of a better result. |
| Bin capacity | 0.6 liter | 0.77 liter | It determines how frequently you have to refill, empty or begin a new batch. |
Trade-offs
What each pick costs you
With Dreame Z30
- Eco mode with a non-motorized tool is how the 90-minute claim is reached.
With Dyson V15 Detect
- Its small bagless bin means you still come into contact with dust when you empty it.
