Great Deal

Dyson's most powerful cordless stick vacuum, now $839.99 after an 18% drop from $1029.35. HEPA filtration, 280AW suction, and a Fluffy Optic head that lights up dust you can't see. Built for whole-home cleaning on carpet and hard floors.

What we like

280AW suction, Dyson's most powerful cordless
Whole-machine HEPA traps 99.99% down to 0.1 microns
Up to 70 minutes of run time in Eco mode
Fluffy Optic head lights up invisible hard-floor dust

Watch out for

34.47 lbs shipping weight makes it heavy overhead in handheld mode
Boost mode drains the battery in minutes

Tip: Run it in Auto mode for the longest runtime and the particle-count screen accuracy; Boost is best saved for spot messes.

Our Take

Best for: Pet owners and allergy sufferers who need HEPA filtration on both carpet and hard floors.

The Gen5detect sits at the top of Dyson's cordless lineup, and it earns the spot. The Hyperdymium motor pushes 280 air watts, roughly double what the V8 produces, so carpets that used to need two passes give up debris in one. 1 microns, which matters if allergies or pets are part of the household. The two cleaner heads cover the full floor. The Fluffy Optic head angles a green light across hard floors and exposes dust that is otherwise invisible, and the Digital Motorbar head has de-tangling vanes that comb long hair and pet hair off the brush bar as it spins. The particle counter on the LCD screen grows and shrinks in real time, so you can see when an area is actually clean instead of guessing. At the end of a run it shows a summary of what you picked up. The tradeoffs are real but predictable. Boost mode empties the battery fast, and with the wand attached for overhead work the whole assembly gets heavy. Auto mode is where the runtime and the smart suction ramping live, and that is how most people will actually use it. 68. For a flagship cordless with HEPA and a 2-year warranty, that is a solid entry point.

Price Analysis

At $839.99 the Gen5detect is down 18% from its $1029.35 list price, saving you $189.36. That is below the 90-day average of $957.79 and well under the 180-day average of $903.68, so this is the cheapest this vacuum has been in the past six months. Buyers who have been waiting on a flagship Dyson drop have a good window here.

Common Questions

How long does the Dyson Gen5detect battery last?

Up to 70 minutes in Eco mode, around 40 minutes in Auto mode with the motorized head running, and about 10 minutes in Boost. Runtime shifts with floor type, debris level, and which attachment is on the wand.

Does the Gen5detect work on carpets and hard floors?

Both. The Digital Motorbar head deep cleans carpet and de-tangles hair, while the Fluffy Optic head handles hard floors and lights up fine dust with an angled beam.

What does the HEPA filtration on the Gen5detect actually trap?

The sealed whole-machine system captures 99.99% of particles down to 0.1 microns in Boost mode, including viruses like Influenza A. Every other mode holds at least 99.97%, so nothing you vacuum up goes back into the air.
