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
- SV22 / V15 Detect
- What that covers
- Dyson vacuum; filter, battery, cleaner head and LCD fault behavior vary by model.
- Not applicable to this hardware
- This Dyson V15 Detect 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)
- A CORDLESS STICK vacuum with a click-in, replaceable battery. Runtime depends heavily on mode: Boost/MAX drains the battery in minutes by design, so 'short runtime on MAX' is normal — Eco mode runs far longer. A vacuum that pulses/stops is usually a blocked airway (bin, filter, wand) triggering the protection, or a battery too hot/cold.
- Laser + piezo dust detection
- The V15 projects a green laser on the floor to reveal fine dust and counts particles on its LCD screen. If the laser/counts seem wrong, that is a detection feature, separate from suction; the laser only works on hard floors at a low angle.
- Filter & airway
- One washable lifetime filter — wash it monthly and let it dry fully (24 hours) before refitting; a damp or clogged filter causes suction loss and pulsing. Clear the wand, bin inlet and cyclone of blockages for 'no suction'.

Exact questions
Questions that only have an answer for the Dyson V15 Detect 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.
My Dyson V15 keeps pulsing / stopping and starting.+
Pulsing is the V15 protecting itself, almost always from a blockage or a filter problem. Check the whole airway — empty the bin, wash the filter and let it dry a full 24 hours, and clear the wand, cleaner head and cyclone of hair and debris. A battery that is very hot or very cold also causes cut-outs; let it reach room temperature. On Boost/MAX the battery also simply runs down fast, which is normal, not a fault.
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.
