Dyson Dyson Gen5detect Absolute

The best specification in this ranking, attached to the worst reported test result.

On paper it is formidable: 280 Air Watts from a motor spinning to 135,000 rpm, HEPA filtration sealing 99.99% of particles down to 0.1 µm across pre- and post-motor stages, a removable single-click 10-cell battery, and a tool set covering a Slim Fluffy head with laser dust detection, a Digital Motorbar and a hair-removal tool. It weighs 3.5 kg.

Stiftung Warentest reportedly graded it "Mangelhaft" — deficient — in issue 02/2024, at a €900 test price. In durability testing, the plastic housing melted at the battery contacts on two units.

We are reporting that carefully, because it matters and because our sourcing is second-hand. The finding reaches us through Notebookcheck's summary of the test, not from test.de directly. Verify it against test.de before treating it as settled. But it is a specific, physical, reproducible failure mode described in a named issue of a named publication, not a vague complaint — and it concerns heat at a lithium battery's contacts, which is not a trivial category of fault.

Dyson publishes 70 minutes maximum, in eco mode on hard floors. No boost figure, no bin capacity, no noise level and no battery watt-hour figure appear on the product page.

At €692.53 street against €899 RRP, and against a €580 V15 Detect from the same manufacturer with a similar feature set, the case for this specific model is hard to make until that Stiftung Warentest result is either confirmed or refuted.
