In one specific comparison, RTINGS’ 2026 tests favor the Dyson V15 Detect over the Shark PowerDetect Cordless IP1251 overall, while finding similar battery life. That result is useful for shoppers considering those two US-market models, not a verdict on every vacuum either brand makes.
What the V15 Detect vs. PowerDetect comparison shows
RTINGS’ comparison lists test updates of September 22, 2026 for the Dyson V15 Detect and August 4, 2026 for the Shark PowerDetect Cordless IP1251. Its overall assessment favors the V15 Detect, citing stronger debris pickup across a wider variety of surfaces, lighter construction, a larger dustbin, and faster recharge. Battery life was similar in its tests. These are findings from RTINGS’ testing of this pair; they do not predict the result in every home or establish that Dyson is always better than Shark.

RTINGS reports surface-specific pickup results, so a single overall verdict can conceal what matters most to you. Check the comparison’s individual results for your flooring and the kind of debris you need to clean rather than treating an overall score as a substitute for your own priorities.

Choose by the cleaning job, not the logo
Carpet and mixed floors
Match pickup results to your home’s surfaces, especially if you have carpet as well as hard flooring. Floorhead design and how a vacuum performs on each surface can matter more than a brand-level reputation. RTINGS’ comparison separates its results by surface; the models do not perform identically across those measures.
#1 Best Overall
- HYPERVELOCITY SUCTION: Provides incredible suction power and cleaning performance for everyday messes.
- FLOORDETECT TECHNOLOGY: Detects floor type and automatically adjusts brushroll speed for maximized performance on all surfaces – no switching of nozzles required.
- NO HAIR WRAP: Self-cleaning brushroll for powerful pet hair pickup with no hair wrap.
- UP TO 50 MINUTES RUNTIME*: For whole-home, deep cleaning. *Measured at the handvac in standard mode.
- HEPA FILTRATION & ANTI-ALLERGEN COMPLETE SEAL: Captures & traps over 99.97% of dust & allergens*, keeping them out of the air you breathe. *Based on ASTM F1977 of particles .3 microns and larger. Allergens refer to non-living matter.
Pets and hair
Look for both pet-hair pickup evidence and the exact floorhead included with the model you are buying. Shark’s official catalog describes its PowerPro Pet cordless model as having a self-cleaning PowerFins nozzle and FloorDetect automatic brushroll adjustment. Those are claims about that specific listed model, not all Shark cordless vacuums, and they are not a substitute for independent pickup results. Check Shark’s cordless catalog for the current model description and configuration.
Weight and overhead cleaning
If you regularly clean stairs, furniture, or above-floor areas, consider how the vacuum feels in your hand as well as its total weight. RTINGS found the V15 Detect lighter by both measures in its comparison with the IP1251. A lighter machine may be easier to maneuver, but handle balance and the tools supplied still affect comfort.
Rank #2
- STICK VACUUM FOR CARPET AND FLOOR: With the Shark Cordless Anti-Allergen Pet Power Vacuum, cleaning feels simpler than ever. Powered by a rechargeable battery, this vacuum delivers up to 50 minutes of runtime* covers spring pet shedding and everyday messes at home.

- SHARK: Our engineers innovate high-performance technology to solve the problems you know, and even the ones you don't. From air purifiers to cordless vacuums and steam mops, Shark powers a better clean for your home.
Runtime and charging
For the tested V15 Detect and IP1251 pair, RTINGS reports similar battery life and a faster recharge for the Dyson. Separately, Shark advertises up to 50 minutes of runtime for its PowerPro Pet model; this is a manufacturer-stated maximum for that model, not a measured runtime for the IP1251 or a guarantee of runtime in every setting. Dyson’s catalog also includes model-specific specifications, so compare the exact vacuum’s stated runtime and charging time rather than transferring a figure across a product line.

Dyson’s official cordless catalog says: “Dyson’s fully-sealed HEPA filtration traps microscopic particles and allergens – and expels cleaner air.” This is Dyson’s manufacturer statement, not an independent comparison result, and the stated specification should be checked against the exact model and configuration. Do not assume every Dyson or Shark cordless vacuum uses the same filtration system. Review Dyson’s cordless catalog and confirm the details on the product listing for your market.

Compare the exact bundle and ownership terms
Model names alone may not identify what you will receive. Before deciding, compare like-for-like listings in the same country and check which tools, floorheads, dock or emptying station are included. Prices, availability, and packages change, and the evidence here does not establish a current fair-price comparison for the V15 Detect and IP1251.
Quick Recap
Best Value

- PERFECT FOR PET HAIR: The PowerFins self-cleaning brushroll delivers powerful pet hair pickup across carpets and hard floors and helps prevent hair wrap, while the exclusive Motorized Hand Tool tackles embedded pet hair on stairs, upholstery, and furniture
- Warranty: Read the warranty terms for the exact model and your region. Dyson’s V16 Piston Animal product page, for example, lists a two-year limited warranty for that product; it is not evidence of the warranty for the V15 Detect or a direct comparison with Shark. See Dyson’s V16 Piston Animal product page.
- Replacement parts: Verify filter and battery compatibility by exact model number before buying. RTINGS lists filter identifiers 970013-02 and HEPA filter 970013-03 for the V15 Detect, and XPRMFIP1000 and HEPA filter XPMHIP1000 for the IP1251. These identifiers are a starting point, not confirmation of current fit or availability; check with the manufacturer. RTINGS reports that both comparison models have swappable, user-serviceable batteries.
- Local configuration: Confirm the SKU, included accessories, warranty, and product availability in your country. The RTINGS comparison is US-market oriented, so its model names and findings may not map to every regional package.
A practical decision rule
- Identify your highest-priority task. Decide whether carpet pickup, pet hair, mixed floors, lighter handling, filtration, or ease of maintenance matters most.
- Compare exact models on that task. Use model-level test results where available, and distinguish independent findings from manufacturer specifications.
- Check the delivered configuration. Match included tools and floorhead, warranty, replacement-part compatibility, and current local price—not just the headline model name.
- Use the brand comparison as context, not a shortcut. RTINGS also maintains a broader Dyson vs. Shark brand guide, but your final choice should still reflect the particular models and bundle available to you.
