## The top picks

- **Most people: a lower-priced cordless that handles pet hair:** Shark Cordless Pet Stick Vacuum (IY143H). Shark's lower-priced cordless stick: a self-cleaning brushroll for pet hair, FloorDetect to adjust brush speed, headlights, HEPA filtering and a handheld mode.
- **A lighter, simple Dyson for small homes, cars and stairs:** Dyson V8 Cordless Vacuum. Dyson's entry cordless: a Motorbar head with hair-removal vanes, two power modes, sealed whole-machine filtration and a 2-year warranty, at 5.6 lb.
- **A self-emptying cordless with long run time:** Shark PowerDetect Clean & Empty Cordless Stick Vacuum (IP3251). Shark's top cordless: an auto-empty dock that holds up to 45 days of dirt, a dual-brushroll head that picks up in both directions, a bendable wand and up to 70 minutes of run time.
- **A premium cordless with a dust-revealing light and a screen:** Dyson V15 Detect Cordless Vacuum. Dyson's detail-focused cordless: a laser-style light that reveals dust on hard floors, an LCD that counts particles and shows run time, auto power adjustment, a wall dock and a mini motorized tool.

Most people should get a Shark. The **[Shark Cordless Pet](https://twelvetabs.com/reviews/shark-vs-dyson/#pick-1)** gives you a self-cleaning brush and pet-hair pickup at the lower price. Get a Dyson if weight matters most, with the lighter **[Dyson V8](https://twelvetabs.com/reviews/shark-vs-dyson/#pick-2)**, or if you want a dust-revealing light and a screen, with the **[Dyson V15 Detect](https://twelvetabs.com/reviews/shark-vs-dyson/#pick-4)**.

Stepping up from there, the **[Shark PowerDetect](https://twelvetabs.com/reviews/shark-vs-dyson/#pick-3)** adds a self-emptying dock and a long run time, and it is the heavy one of the four. We compared two price tiers because "Shark vs Dyson" is really a question about price: at each tier, Shark lists more run time or more features for less, and Dyson lists the lighter, more precise machine.

## The short version

- **Pet hair and a tight budget?** A Shark. Its self-cleaning brushroll is built for hair that wraps around a brush.
- **Small home, stairs or the car?** The V8. At 5.6 lb it is the lightest of the four.
- **Hate emptying the bin?** The PowerDetect. Its dock empties the vacuum and holds up to 45 days of dirt.
- **Want to see the dust you are missing?** The V15 Detect. Its light shows dust on hard floors, and its screen counts particles.
- **Need the longest run time?** The PowerDetect, listed at up to 70 minutes in eco mode, then the V15 at up to 60.

## How to choose between them

Good Housekeeping's summary is that the two brands take different approaches: Shark leans on versatility and value, and Dyson on cyclone suction and smart sensors that detect and count dust.

- **Weight.** Dyson lists 5.6 lb for the V8 and 6.8 lb for the V15. Shark's two listings show no weight, and owners put the PowerDetect at about 8 lb. If you carry it up stairs, this matters.
- **Run time.** The entry Shark and the V8 are both listed at up to 40 minutes. The V15 is listed at up to 60 and the PowerDetect at up to 70, measured in eco mode. Owners of both brands say run time falls at higher power settings.
- **Emptying.** The Dysons eject dirt from the bin with a push. The PowerDetect empties itself into its dock. The entry Shark has a dust cup you empty by hand.
- **Brush head.** Shark uses self-cleaning or dual brushrolls, Dyson uses detangling vanes. Both claim to cut hair wrap.
- **Warranty.** Good Housekeeping says Dyson warranties its cordless vacuums for two years and Shark offers limited warranties from one to seven years, so check the one on the model you buy.

## Our picks in detail

### 1. Shark Cordless Pet (IY143H): best for most people

**Why it made the list**

- The self-cleaning brushroll is aimed at long hair and pet hair.
- FloorDetect adjusts brush speed to carpet or hard floor, and headlights show dust under furniture.
- It converts to a handheld and has HEPA filtering.
- It costs the least of the four.

**Drawbacks**

- Run time is up to 40 minutes.
- The listing shows no weight, and some owners of Shark's cordless line call them heavy.
- Owners say the dust cup is small and fills quickly.

**Skip it if** you want a screen, a dust light or the lightest vacuum.

### 2. Dyson V8: best lightweight Dyson

**Why it made the list**

- At 5.6 lb it is the lightest of the four, and it converts to a handheld for cars and stairs.
- The Motorbar head has vanes that clear hair, and the bin ejects dirt in one push.
- It has two power modes and whole-machine filtration, and a two-year warranty.

**Drawbacks**

- Up to 40 minutes, and some owners say they get far less at full power.
- A few owners find the handle awkward for large hands or sore on the wrist.
- It has no dust light, no screen and a small bin.

**Skip it if** you have a large home or lots of carpet.

### 3. Shark PowerDetect Clean & Empty (IP3251): best self-emptying cordless

**Why it made the list**

- The dock empties the vacuum for you and holds up to 45 days of dirt.
- It lists up to 70 minutes in eco mode and a bendable wand that folds for storage.
- It detects dirt and carpet and boosts power on its own.

**Drawbacks**

- Owners put it at about 8 lb with the motor at the handle, which tires some wrists.
- One owner got about 10 minutes at full power, and another says the head locks by accident.
- Filters need frequent cleaning, and the dock can clog with hair.

**Skip it if** you carry your vacuum upstairs or want something light.

### 4. Dyson V15 Detect: best premium Dyson

**Why it made the list**

- Its dust light shows dirt on hard floors, and its screen shows particles, power mode and run time.
- It has up to 60 minutes of run time, an automatic power mode, a wall dock and a mini motorized tool.
- It has a two-year warranty.

**Drawbacks**

- It costs the most of the four.
- Owners say emptying can leave dirt stuck in the bin, and a few report a sticky attachment or a power button that failed.
- At 6.8 lb it is heavier than the V8.

**Skip it if** you do not need the light and screen.

## What owners complain about

- **On Shark:** short and uneven battery at full power, weight, small dust cups, slow charging, and brittle plastic around the power button on one listing. Several of these come from owners of Shark's wider cordless line, since its Cordless Pet listing shares its reviews with older models.
- **On Dyson:** short battery at full power, awkward handles, messy bin emptying, and a few quality complaints, such as a failed button and a missing tool. Amazon's summary calls the V8's value mixed.
- **On both:** reviews on every model are divided on battery, so match the run time to your floor space.

## What we left out, and why

We read four listings, two per brand, and 35 reviews.

- **Robot, corded and wet-dry vacuums.** Different products.
- **Dyson V10, V12 and V16, and Shark Vertex and Stratus lines.** We compared one lower and one higher tier per brand, so the nearest of these sit between our picks.
- **Hair dryers and stylers.** The same two brands, a different question.
- **Used and renewed vacuums.** We compared only each page's new buy-box offer.

## Questions people ask

### Is Shark or Dyson better?

Neither wins everywhere. At the lower tier, a Shark gives you a self-cleaning brush and a long run time for less. Dyson wins on weight and on detail features like the dust light and screen.

### Is a Dyson worth the extra money?

If you want the lighter body or the dust light and screen, yes. If you want simple, strong pet-hair pickup, a Shark is enough.

### Which brand has the longer warranty?

According to Good Housekeeping, Dyson covers cordless vacuums for two years, and Shark's limited warranties run from one to seven years depending on the model.

### How did TwelveTabs choose between them?

We read the Amazon listings for two Shark and two Dyson cordless sticks, their spec sections, Amazon's review summaries and the lower-star reviews we could see, plus Good Housekeeping's comparison. We put the facts side by side and checked each against its listing.

## How we researched

On October 13, 2026 we read the Amazon listing pages for two Shark and two Dyson cordless stick vacuums at two price tiers, including each page's spec sections, Dyson's own range chart, Amazon's review summaries and the lower-star reviews we could see. We also read Good Housekeeping's Shark vs Dyson article and checked Google's top results for this question. AI wrote this guide from that research.

Shark's listing pages did not show weight or suction ratings, and the Shark Cordless Pet listing's reviews cover Shark's wider cordless line, so we treated its complaints as brand-level. Sizes, colors and kits change the price.
