Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It has no dock and a 0.76L bin. You empty it by hand every few rooms. The Shark PowerDetect empties itself into a 2L base that holds 45 days of debris and costs $261 less — with this pick you are paying for cleaning power, not convenience.

Traps — this verdict avoids
Why the Dyson Gen5detect is right for you
It avoids every trap below — and for anyone, no price cap, it is the pick because it delivers:
The runtime on the box is Eco mode
Battery claims are measured in Eco with a non-motorized tool. With the brushroll running on Auto you get 40-60% of the number: the Gen5detect's 70 minutes is about 40 on Auto and 15 on Boost, and the Tineco A90S's 105 minutes is measured with the crevice tool, not the main brush.
Tier no longer predicts price
Mid-2026 reset this category. The Dyson Gen5detect fell to ~$661 — below the V15 Detect Plus at ~$790 — while the Tineco Pure ONE S70 climbed from ~$399 to ~$569. Prices swing 20-40% during sales events, so re-check any figure more than a few weeks old.
The battery is the real running cost
Filters are washable but need replacing roughly annually, and the lithium-ion pack is the largest recurring cost on any cordless. Use the manufacturer's own: CPSC has warned consumers to stop using third-party packs sold as Dyson-compatible after fires, and in July 2026 recalled about 3,660 Rowenta cordless vacuums over fire and burn hazards. None of the picks here is under recall as of 2026-08-06.
