GET $100 OFF: Get up to $100 off Shark vacuums, air purifiers, and more during Walmart's Shark Days sales event.

That means you get a high-quality, highly-rated, super-powerful vacuum for less than $100. We know — we can't believe it either.

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,
