    Dream L40 Ultra

    First robot vacuum I’ve purchased. I was very skeptical of robot vacuum and after tons of research and videos from YouTube I decided to go with the Dreame L40 Ultra. It has been the best investment my wife and I’ve ever made. It does everything we could ask for. We both despise vacuuming and mopping, so having this vacuum do it for us is worth every penny. I couldn’t recommend buying this vacuum enough just stopped thinking and buy it. You won’t regret the purchase. If it only last a year it’s worth the money.

    Love this robot!

    Although there is a bit of a learning curve and too few resources to go into depth about the product while you learn, I have to say my robot has functioned exceptionally well and after a few weeks I am very satisfied with my purchase and am really digging the extra help around the house! Thank you Dreame! I would recommend to Dreame that they make a lot more “how to” videos or guides for each setting in the app, for using it on multiple floors, for maintenance, etc.

    Game changer!

    This is my first advanced robot vacuum since the early days of robot vacuums (which I quite honestly never used due to the many issues early on). I’ve probably spent months scouring the internet for recommendations and opinions and finally found something that generally received great and balanced reviews in all the major categories and pain points for the average user.
    I have two young children and I mostly work from home. So my home operates as a full time hotel, restaurant, office, gym, theatre, daycare, library and kids playhouse. It starts off clean at 7 am and is a wreck by 7 pm.
    I’ve only had the Dreame L40 for 1 week but I could tell you now after 1 week of use that Dreame nailed it. My floors look like brand new and I barely lift a finger!
    Let’s start with the app. Great features and intuitive customizations to set it and forget it. The L40’s mapping is spot on and you can customize the mapping with objects, no-go zones etc.
    Next is the vacuum power. I have three (expensive) vacuums in my house. One corded and two cordless. The L40 has great suction power for a robot but I didn’t expect it to clean my rugs (high pile and low pile) better than my regular vacuums, but it does. The swing out arm reaches into places and works great.
    Mopping is awesome. My hardwood floors have never looked better and the swing out mop pads get into area I wouldn’t get with a mop.
    Plenty recognition and avoidance, it recognized 99% of objects it should stay away from but it did eat a crayon once I would’ve hoped it avoided.
    Self maintained! Can’t beat that ever, and the machine and dock look like a furniture piece next to my kitchen.
    Overall, I believe Dreame did an awesome job with this one it was worth the money.
