Dyson V15 Detect vs Shark PowerDetect

Specifications at a glance

The Dyson listing gives more hard numbers than the Shark one. Where Shark's listing is silent, check Shark's own product page for the exact model code, as PowerDetect bundles differ.

Detect sensors: what each one does

Dyson's piezo sensor sits in the airflow and sizes and counts dust particles as they pass. When it detects more, it raises suction, and the LCD screen shows what has been picked up. This gives you feedback on when an area is clean. In Auto mode, DLS technology in the High Torque head monitors brush bar resistance 360 times a second and adapts power to the floor.

Shark spreads its sensing across four features. DirtDetect raises suction when it senses dirt. FloorDetect senses carpet or hard floor and changes brush-roll speed. EdgeDetect doubles suction at edges and corners against skirting boards. DirectionDetect keeps suction high when you pull the vacuum back towards you, which the listing notes is a weak point on many cordless vacuums. Shark does not list a screen readout, so you get the automatic adjustment without the counts.

Anti-tangle heads and hair

Both machines are sold as pet versions. The Dyson V15 Detect Animal comes with a High Torque head with a de-tangling comb that clears hair from the brush bar, plus a Hair screw tool whose conical brush bar spirals hair off and into the bin. That tool is useful on stairs, sofas and pet beds.

The Shark PowerDetect uses Anti Hair Wrap Plus, a chevron-pattern brush-roll with internal combs that remove hair as you clean. Neither design is guaranteed to stay perfectly clear with very long hair, so check the brush every few weeks. Our anti-hair wrap explainer covers how these heads work.

Emptying the bin and storage

The Dyson V15 Detect Animal has a 0.76 L bin, one of the larger bins on a stick. Dyson's V15 uses a point-and-shoot style emptying action where you push a lever to release debris into a bin, so hold it inside the bin bag to limit dust. It is stored on a wall dock, so plan a spot near a socket.

Shark's PowerDetect listing does not give a bin size. Some PowerDetect versions in Shark's range are sold with a self-emptying base, while others are stick only, so check the model code. The Flexology wand bends to reach under furniture and lets the vacuum fold over for compact freestanding storage. If you want the dock to do the emptying, see our guide to the best cordless vacuums with a self-emptying dock.

Runtime and batteries

Dyson lists up to 60 minutes for the V15 Detect Animal. Like every maker, Dyson measures its maximum in the lowest power setting, usually with a non-motorised tool, so the motorised head on boost will run for much less. The V15 is widely documented as having a click-in battery you can swap for a spare.

Shark's PowerDetect listing does not state a runtime, so check Shark's product page for your exact model. Many Shark cordless models use a removable battery that can charge off the vacuum. To estimate whether one charge covers your home, enter the eco and boost figures into our runtime planner.

Note:Charge with the maker's charger or an approved replacement. Stop using any battery that is swollen, damaged or smells of burning, and recycle old packs at a battery recycling point, never in household waste.

Which flagship should you buy

Both are premium machines, so the right choice comes down to the features you will use every week. Our best cordless vacuum cleaners guide covers both alongside other strong options.

1. 1

   If you want to see proof of what is being picked up, choose the Dyson V15 Detect for its particle sensor and LCD screen.

2. 2

   If edges, skirting boards and pulling backwards matter most, choose the Shark PowerDetect for EdgeDetect and DirectionDetect.

3. 3

   If you have no wall space for a dock, the Shark's folding Flexology wand and freestanding storage are easier.

4. 4

   If you clean a larger home in one go, compare stated runtimes and bin sizes, where the Dyson listing gives clearer figures.

5. 5

   If you want the dock to empty the bin, check which PowerDetect bundle includes a self-emptying base.

Frequently asked questions

Does the Shark PowerDetect have a screen like the Dyson V15? The Shark PowerDetect Cordless Pet listing does not mention a screen. It adjusts suction and brush speed automatically using its sensors. The Dyson V15 Detect has an LCD that shows particle counts as you clean.

Which is better for pet hair, Dyson V15 or Shark PowerDetect? Both have anti-tangle heads designed to stop hair wrapping round the brush. The Dyson Animal bundle adds a Hair screw tool for furniture and stairs. The Shark adds edge suction and a bendable wand for under furniture. Either is a reasonable choice for a pet home.

Is the Dyson V15 heavier than the Shark PowerDetect? The Dyson V15 Detect Animal is listed at 3 kg. The Shark PowerDetect listing does not state a weight, so check Shark's product page and compare in-use weights measured the same way.

Does the Shark PowerDetect empty itself? Some PowerDetect models in Shark's range come with a self-emptying base and some do not. Check the exact model code and what is in the box before you buy.
