I’ve been using the Dreame L40 Ultra for a few months now, and overall, it’s been a fantastic addition to my cleaning routine. With pets at home, hair and dirt pile up quickly, but this vacuum manages to keep things spotless. I love how quiet it is—even the charging station operates softly. The customization options through the app are impressive, allowing me to schedule and adjust cleanings exactly as I need. Plus, the built-in camera is a fun bonus; I didn’t expect to use it much, but it’s handy for checking in on my cat!

That said, it’s not without its quirks. The AI and navigation software feel a bit unfinished at times; for instance, it sometimes struggles to go under low furniture or leaves streaks on the base after a run. The water container also could be easier to handle—filling it requires a steady hand! Despite these minor issues, I’m overall very happy with this vacuum, and it’s made keeping my home clean much easier.

The Dreame X40 Ultra is a solid upgrade, especially for those familiar with models like the Roborock S7 Ultra MaxV. It excels at mopping and navigating around obstacles, while the large water tanks and sewage connection add convenience. However, the automatic stain cleaning feature underdelivers, as it fails to scrub tough spots as expected. Additionally, the vacuum sometimes scatters small debris rather than picking it up. Despite these flaws, it remains a reliable flagship option for those seeking strong mopping performance and smart navigation. Overall, it’s a good choice, but expectations for a "flagship" experience could be higher.
