Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: SV23 / Gen5detect
What that covers: Dyson vacuum; filter, battery, cleaner head and LCD fault behavior vary by model.
Not applicable to this hardware: This Dyson Gen5detect cordless vacuum does not have the hardware for: robot vacuum will not return to or charge on the dock; robot vacuum gets lost, stuck or misses rooms. Those symptoms have no page here for this model rather than a page that guesses.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — cordless stick (battery): Dyson's top CORDLESS STICK with a click-in battery. Runtime is mode-dependent — the highest power mode drains fast by design. Pulsing/stopping is usually a blocked airway or a battery too hot/cold.
Laser + HEPA: Green laser dust detection and particle counting on the LCD, plus a fully-sealed HEPA system. The laser is a hard-floor detection feature separate from suction.
Filter & airway: Washable filter — wash monthly, dry 24 hours before refitting. Clear the wand, bin inlet and cyclone for suction loss.

Exact questions

Questions that only have an answer for the Dyson Gen5detect cordless vacuum

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

How long should my Dyson Gen5detect battery last per charge?+

It depends entirely on the mode and cleaner head — the highest-power mode gives only a handful of minutes by design, while Eco mode runs much longer, and a motorised floor head draws more than a non-powered tool. So a short runtime on max power is expected, not a fault. If runtime has dropped a lot across all modes over time, the click-in battery has aged and can be replaced.

Structured depth, not empty permutations

Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.

Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
