Dyson V15 Detect vs Shark PowerDetect Speed

The Dyson V15 Detect ($850) shows you the dust: a green laser lights up the floor and a piezo sensor counts particles on its screen. The Shark PowerDetect Speed Cordless Vacuum (IA1241) ($430) skips the laser for automatic dirt, floor and direction sensing, a self-cleaning brushroll and a HEPA filter, and Shark backs it with a 5-year limited warranty. That's $420 less.

Where each one wins

Dyson V15 Detect is better for

  • Tech Advisor says the green laser reveals dust you can't normally see, and the piezo sensor shows a live dust count on the screen.
  • The battery clicks out in seconds, so a spare can be swapped in mid-clean (Tech Advisor).
  • Bigger bin (0.76 L vs 0.5 qt), shorter charge (4.5 vs 6 hours) and slightly lighter (6.8 vs 7.1 lb).

Shark PowerDetect Speed is better for

  • Shark lists a 5-year limited warranty, versus 2 years for the V15.
  • HEPA filter, plus Shark's TurboPro Detect self-cleaning brushroll.
  • Shark rates it up to 60 minutes, the same headline as the V15, though only in Eco mode with a non-motorized tool.

What you give up with the cheaper one

The 60-minute runtime is in Eco mode with a non-motorized tool.

Which should you buy?

Dyson V15 Detect: You want to see fine dust with the laser, track what you pick up on the screen, and keep a spare battery for big homes.

Shark PowerDetect Speed: You want automatic dirt sensing, a HEPA filter and a longer warranty, and don't need the laser or a swappable battery.

Quick answers

Is the Shark PowerDetect Speed as good as the Dyson V15?

They take different routes. The V15 adds a green laser and a particle counter, a click-in battery and a 0.76 L bin. The Shark has automatic dirt, floor and direction sensing, a HEPA filter, a self-cleaning brushroll and a 5-year limited warranty, for $420 less.

Which lasts longer on a charge?

Both are rated up to 60 minutes. Shark's figure is for Eco mode with a non-motorized tool, and Tech Advisor got about 20 minutes from the V15 vacuuming carpet in Auto mode, so expect much less than 60 minutes on carpet from either.

Does the Dyson V15 or the Shark have a longer warranty?

The Shark. Shark lists a 5-year limited warranty for the PowerDetect Speed, and the Dyson V15 Detect comes with a 2-year parts and labor warranty.

How we pick the swaps

Real products, labeled by type

Every swap is a product sold in the US that does the main job of the original. Close match is another brand with similar features, Same brand, cheaper is an older, smaller or renewed model from the same maker, and Budget pick is the cheapest thing that still does the job. On each page, Closest match is the close match nearest the original in price, and Lowest price is the cheapest swap. We compare published specs, retailer listings and reviews; we don't test products ourselves.

The trade-off is always shown

A cheaper product is cheaper for a reason. Each swap says what you give up, like weaker noise cancelling, a smaller screen or a shorter warranty, so you can decide if the savings are worth it.

Prices are checked, not guessed

Prices are typical US prices from retailer listings and price trackers, last checked October 2026. They are not live Amazon prices, which change often. When a price couldn't be confirmed, the page says “Check price on Amazon” instead of showing a number.

How the site is paid

Amazon buttons are affiliate links: Cheaper Swap earns a small commission if you buy, at no extra cost to you. Commissions don't decide what is listed. Google AdSense may also show ads on the site.
