Best robot vacuum deal: Eureka E20 Plus is at its all-time low

SAVE $140: The Eureka E20 Plus robot vacuum and mop is $349.97 at Amazon (22% off) — plus, take an extra $40 off with a coupon through Aug. 9.

If your cleaning needs a bit more automation, Amazon has a huge robot vacuum deal live right now.

As of Aug. 7, the Eureka E20 Plus robot vacuum and mop is on sale at Amazon for $349.97 — a solid 22% off its typical $449.99 price. In fact, according to price tracker camelcamelcamel, that's the lowest price ever recorded. And as a bonus, there’s an additional $40 off if you check the limited-time coupon box, valid through Aug. 9. That brings the price down to just $309.97, a total saving of $140.

As far as the specs from Eureka go, this robot doesn’t mess around — standing out amongst the other robot vacuums out there. It packs a powerful 8000Pa suction system that dives deep into both carpets and hard floors, lifting pet hair, dust, and debris with ease. Its auto-lifting mop knows to raise itself 10mm when crossing over carpets, meaning no accidental soggy rugs.

The self-emptying, bagless base is another major win for fans of high-quality vacuums. It can store up to 45 days of dirt, so you can skip the constant bin emptying (and skip buying expensive replacement bags as well).

The E20 Plus also features DuoDetect AI 3D Obstacle Avoidance with dual LiDAR sensors, which helps it gracefully dodge cables, shoes, or pet bowls — even in the dark. What’s more, if you’ve ever battled a hair-clogged roller, the anti-hair-tangling V-shaped brush is a pet owner's dream, reducing wrap by up to 14%.

Control is as modern as it gets, with full app support, voice commands, and smart navigation that just works.

If you’re ready to spend less time cleaning and more time doing literally anything else, this deal delivers high-end features without the high-end price. Just don’t wait, because that extra $40 coupon is gone after Aug. 9.
