Dreame x40 is currently the best vacuum out there.

It has the most tested software, more so than the l40. 6400mah battery, 4.0l water bin, tricut brush that increases pickup, quieter than most robots, better price than any other. Really good mopping, auto cleans mop pads every x sqft.

Good obstacle avoidance. Good carpet performance.

Eufy s1 pro is a close second if mopping is what you’re looking for. However if you are looking for a robot that will last you time without wanting another (happens to all of us) for me the dreame x40 ultra scratched that itch.

Sorry if you disagree, but I’ve had 4 robovacs and I am a software engineer. This is the most amazing piece of tech I have ever seen.
