Though Prime Day 2025 doesn't officially start until July 8, Amazon has already dropped the prices on a ton of self-emptying robot vacuums. Whether you're not trying to spend more than $200 or $300 or you're eyeing an auto-empty dock that also washes and dries a mopping robot vacuum's mopping pads, there's a deal for you in this list.

Right now my favorite hybrid Shark PowerDetect 2-in-1 Robot Vacuum and Mop is down to just $649 from $999 on Amazon. Meanwhile, the iRobot Roomba Plus 405 is now $399, down from $799. That’s an incredible 50% discount — saving you some serious cash.

Alternatively, there's the Hoover Robot Vacuum Cleaner for £199 down from £249 direct from Hoover, a powerful bit of kit that is suitable for both carpets and hard floors, has powerful suction and even returns to the base to recharge when the battery runs low all by itself.
