Dyson V15 Detect
$850
Search on Amazon ↗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.

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.
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.
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.
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.
As an Amazon Associate I earn from qualifying purchases. It never costs you more.
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.
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 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.
