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.

Pros

  • Quiet operation, even in charging
  • Excellent pet hair and dirt cleaning
  • Highly customizable app settings
  • Seamless integration with smart home.
  • Built-in camera for pet monitoring.
  • High-tech features meet daily needs.

Cons

  • Software needs improvement.
  • Bumps into some furniture.
  • Water container design is tricky.
