Find answers to the questions you may have:

How do I select between Daily and Ultimate Modes?

At what point does my L40 Ultra recharge automatically?

Your L40 Ultra vacuum automatically returns to its base station to recharge when the battery drops below 15%, ensuring it’s always ready for the next cleaning task.

How does the DreameTech L40 Ultra manage both vacuuming and mopping functions?

Your L40 Ultra is adept at transitioning between vacuuming and mopping functions without interruption. Equipped with a dual mop system, it effectively scrubs floors to eliminate dirt and stains. The mop's operation can be fine-tuned via the app, allowing you to adjust water flow settings to match the specific needs of various surfaces, ensuring that each area is cleaned appropriately.

Great!

I get my time back. The product has been great!

Very, very effective

The L40 is pretty close to perfect for our home. It does a good job on hard flooring and carpets, and the software is very usable, allowing you to map your home layout so you can specify where to clean.

We got our L40 to replace our new Roborock Qrevo Master, which we tried for a month. We exchanged for the L40 because the Roborock didn't clean up dog hair well, leaving clumps of hair on the carpets. The L40 vacuums the rugs much better, probably because it parks the mops while vacuuming). It also mops hard flooring as well as the Roborock. I also appreciate that it dispenses the mop soap into the clean water automatically.

However, the L40 is definitely slower to clean than the Roborock was. It might be because the L40 navigates strangely, pausing and spinning in place at random times and spots. I've also never had the L40 respond to my voice commands or even confirm it heard me. I haven't tried linking the L40 to our Amazon Echo, so can't speak to how that works. It also gets louder at seemingly random times.

What surprises me is how alike the Roborock and the L40 are, including their software. I know they have the same parent company, but what's the point of having two almost-identical devices competing with each other?

Awesome Vaccumm

This is a great robot vacuum and works like a charm. We have 3 kids that leave crumbs and dirt everywhere. This is the first time we have had consistently clean floors in a while .

Cat poop

I’m very disappointed with this. It ran over cat poop and smeared it everywhere. Besides having to clean the carpet, I had to thoroughly clean the vacuum which was hard to get everything in it. My carpet now needs a deep clean and I’m worried about it doing this again. I have the pet option on so it shouldn’t have done that. Customer service is terrible and doesn’t even reply.

Tried to return unopened vacuum, no response from customer service

I ordered an L40 right before the X50 released, decided to return it to wait for the X50. Send a request to return an unopened L40 more than a week ago and no one has gotten back to me about approving my return. I have heard people talking about Dreame’s poor customer service, this is confirming it for me. Will have to think about whether or not I still want to purchase the X50
