Amazon Prime Day 2025 will start at 12:01 p.m. PDT on July 8 and run through 11:59 p.m. PDT on July 11. That said, there are already some early deals worth browsing if you want to get a head start on shopping.

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.
