SAVE $200: As of July 12, the Dyson V12 Detect Slim cordless vacuum is still on sale for $449.99 at Walmart's Prime Day competition sale, the unimaginatively named Walmart Deals event.

For Prime Day, the price of the Dyson V8 Plus vacuum has been cut, hitting a new all-time low on Amazon. It is currently available for $299, down from its usual price of $469 which is a huge 36% off the original price. The popularity of the V8 shows no signs of slowing: over 30,000 units have been bought in the past month alone.

The Dyson V15 Detect Plus features a laser that will show you invisible dust particles. It's 24% off from Amazon's Prime Day for a discounted price of $570.
