Dreame X40 Ultra Robot Vacuum
I ordered the device in November. Something is wrong with the sensor. So, I requested an exchange. It took them a month to give me a shipping label for the return shipment. Even till now (March), I haven't gotten the exchange device that I requested. Even though I called customer service several times to resolve the issue, all they can do is creating tickets, sending to the advanced team, and not resolving the issue.The whole process has been taking place more than three months now. Really disappointing.
I absolutely love my Dreame X40 Ultra! With two cats and a dog, keeping up with pet hair, muddy paw prints, and everyday messes can feel like a full-time job — but this robot vacuum and mop handles it all effortlessly. It navigates my house like a pro, smoothly transitioning from carpet to tile to hardwood without missing a beat.
The X40 Ultra has an incredible ability to detect carpeted areas and automatically adjust, skipping the mop when needed and giving my carpets a thorough vacuum. The mopping function is equally impressive, leaving my tile and hardwood floors spotless and streak-free.
I’m amazed at how well it maps out the space and learns the layout, so every room gets the attention it deserves. The app makes it super easy to customize cleaning schedules and even target specific rooms or zones. It’s also surprisingly quiet, which is a huge plus with pets around.
If you’re looking for a smart, reliable, and incredibly effective cleaning solution for a multi-surface home — especially with pets — the Dreame X40 Ultra is worth every penny. Highly recommend!
We love ours! Two border collies make for lots of hair and muddy paw prints. This thing is a huge help. Our mop portion stopped letting water out so we sent it in and they fixed it super fast and got it back to us! Great customer service!
Really great at cleaning whilst also avoiding obstacles. Great customization as well. Minus 1 star for some awkward English translations, but it's all understandable
