Amazon Prime Day typically brings great discounts on all sorts of electronics, but it’s a good idea to go for the expensive gear first. We consider robot vacuums to be in that category because, while there are solid affordable models available today,

Prime Day is nearly as good of a time to buy a robot vacuum on sale as Black Friday. It's the first big sale event of the year for many 2025 robot vacuums that just came out in the spring after being announced at CES — most of them were far too fresh to go on sale for Amazon's Big Spring Sale in March.

Robot vacuums are incredibly useful, but tend to be expensive. Fortunately, I found some deep discounts leading up to Prime Day, coming up July 8-11 this year.
