Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
We have included this partly on price and partly because it demonstrates the whole problem with this category in a single listing.
Retailers advertise the same machine as 190 Air Watts and 27,000 Pascals and 90 minutes of runtime. Those first two are dimensionally different quantities describing different things, and quoting both simultaneously is not a specification — it is a choice to present whichever number looks largest to whichever buyer is reading.
Air Watts measure airflow times suction at a point in the airpath. Pascals measure sealed static pressure with zero airflow — a state a working vacuum never occupies, because a vacuum that is not moving air is not cleaning. They cannot be converted into one another, and a machine quoting both is telling you it knows its audience does not know the difference.
The 90-minute runtime claim is the third element, and like every headline figure in this category it will be an eco-mode number. No boost-mode figure is published.
At €187.65 it is genuinely the cheapest option here, and Dreame builds competent machines. But we found no independent European test result for it, no verified filtration class, no noise figure and no battery capacity.
If your budget is fixed near €190, this is the honest position: you are buying on price with almost no verified information. The LG CordZero at €260–289 costs roughly €80 more and comes with a published boost figure, a stated HEPA layer count, a noise measurement and an independent test score. That €80 buys knowledge as much as hardware.

Component scores
Where the score
comes from.
Four components, equal weight, each on a 0–10 scale and each resting on a named source. The overall score is their mean — the full procedure is in the methodology.
What we liked
- €187.65 — the cheapest machine in this ranking
- Dreame builds competent hardware at aggressive prices
- 90-minute maximum runtime claimed
- Widely available across European retailers
Worth knowing
- Marketed as both 190 AW and 27 000 Pa — two incompatible units for the same machine
- No boost-mode runtime published
- No independent European test result found
- No verified filtration class
- No noise figure or battery capacity published
- Pascals describe sealed pressure at zero airflow and tell you nothing about cleaning

FAQ
Frequently asked questions
Is 27,000 Pa a lot?
It is not a meaningful figure at all for comparing vacuum cleaners. Pascals measure sealed static pressure with zero airflow — you block the inlet completely and measure the pressure difference. A vacuum in that state is picking up nothing. Cleaning depends on airflow, which Pascals do not measure. Any listing leading with a Pa figure is choosing a number that sounds large rather than one that describes performance.
Should I spend €80 more on the LG instead?
Probably. For that €80 you get a published boost runtime, a stated 5-layer HEPA filtration, a measured noise figure, a removable battery and an independent test score of around 1.6. The Dreame gives you a price and two mutually incompatible suction claims. In a category with no regulatory floor at all, verifiable information is worth paying for.
