The Eufy 11S Max robot vacuum is on sale for $140 as part of an early Prime Day sale. That's half off, as the typical cost is $280 for this particular model. This is extremely close to a record-low price.

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.

Some people simply don’t like having to vacuum their homes. Cleaning your space doesn’t have to feel like such a chore, especially when there are robot vacuums that can do a much better job of frequently cleaning your space.
