Save $300 on what our testing editors dubbed the best overall robot vacuum. The Roborock Qrevo S, which held up best in an extensive series of tests, is now 38% off on Amazon. I love my Roborock vacuum, especially considering it’s both powerful and versatile enough to deep clean and mop my apartment independently. But even if you like your traditional upright vacuum, you shouldn’t rule out a robot vacuum altogether. And if you do want to delve into the world of robot vacuum, we couldn’t recommend the Qrevo S any more, especially at this price.
