The Shark PowerDetect Cordless Stick Vacuum sells for $429.99, or $499.99 if you go for the version with the auto-empty base. At time of publish it's only available in the US, but an EU and UK release is due before the end of 2024. I've requested pricing info, but based on US figures, it might be around £325 / £375.

The new Shark Cordless PowerDetect Clean & Empty Vacuum has an MSRP of $499, which is comparable to the brand’s other high-end cordless models like the Shark Stratos Cordless Vacuum. This new model is available through the Shark website and is also $499 on Amazon .

Summary: The Detect Pro cordless stick vacuum is smarter, with more advanced detection and auto-adjustment capabilities. The Stratos has more outright suction, and is a little heavier. You can opt to add an auto-empty dock to the Detect Pro.

Overall, the PowerDetect will be the better of the two for most people, just because it's more powerful. However, it is more expensive than the Detect Pro cordless (although not massively) and a bit heavier, too. That's the short version; read on for a more in-depth look all the differences between the Shark PowerDetect vs Detect Pro vacuums.

If this sounds familiar, a robot vacuum can save you time and energy, and thanks to Walmart's Shark Days event, you can grab one for much less. As of Oct. 3, the Shark Detect Pro self-emptying robot vacuum is just $480 at Walmart,
