A Sequel That Goes Backward
The original Dreame L40 Ultra was a solid machine. It earned a fair recommendation in its testing window because it did the basics well at a reasonable price. The Gen 2 was anticipated as the kind of incremental refresh that builds on that foundation — better cleaning, smarter sensors, the usual cadence of a competent brand's sequel product.
What Dreame actually shipped is a robot that strips out premium features without improving the core cleaning. The camera is gone. The solution tank is gone. The dock dirt detect sensor is gone. The mopping — the category most buyers care about at this price tier — actually got weaker because the new pad system doesn't push down with enough pressure to scrub, it wipes.
What's in the Box and First Setup
Setup runs about 15 minutes. The Dreame app handles Wi-Fi pairing (2.4 GHz only, standard for the category) and the first mapping pass automatically. The Dreame ecosystem is mature — that part is genuinely easy.
What's in the box: the robot, the Ace Clean Dry Board dock, a starter dust bag, mop pads, the side brush, and the charging cable. What's NOT in the box that should be at this tier: the solution tank (sold separately) and the TriCut brush (sold separately).
Cleaning Performance: What It Actually Picks Up
Hard Floor & Tile Performance
On hardwood and tile, the 25,000 Pa suction is real — debris pickup is strong, suction is the one ad claim that consistently passes. Where it falls apart is the mop. The Dreame L40 Ultra Gen 2's pads do not push down with enough pressure to actually scrub the floor. They wipe it.
Carpet and Pet Hair
On paper, 25,000 Pa should translate to elite carpet performance. In real-world testing it doesn't — the score reflects "just so-so" results across 90+ days. The TriCut brush upgrade helps the hair number but is an extra purchase.
Mopping Performance
It just doesn't mop very well. Newer robots are starting to put downward pressure. The Mova P10 Pro Ultra Gen 2 does a better job of mopping because it pushes down on the mop pads, which I don't think this one does. At this price tier, mopping is expected to be a competitive category.
Edge and Corner Cleaning
The extending side brush does work — corner reach was one of two Ad vs Reality passes. If you're prioritizing corner cleaning specifically and don't care much about mop pressure, this would be the silver lining. For most buyers, the mop pressure problem outweighs the corner reach win.
Obstacle Avoidance
The Dreame L40 Ultra Gen 2 gets stuck a lot during testing, particularly around chair legs. The camera-free design means no AI obstacle detection, just LiDAR — which works for big stuff but struggles with cords, pet bowls, kid toys, and low-profile clutter.
The Side-by-Side That Decided the Verdict
I ran the Dreame L40 Ultra Gen 2 head-to-head against two other robots in his testing pool: the original Mova P10 Pro Ultra and the new Mova P10 Pro Ultra Gen 2. The result was unambiguous. Both Mova models outperformed the Dreame in nearly every category, especially mopping. The Mova P10 Pro Ultra Gen 2's 12-Newton downward pad pressure and 212°F PTC hot water pad wash genuinely scrub the floor. The Dreame L40 Ultra Gen 2's pads just glide across the surface.
This is the test that locks the verdict. At similar price points, buyers shopping the L40 Ultra Gen 2 can pick a directly comparable Mova model that cleans materially better. There is no remaining argument for the Dreame L40 Ultra Gen 2 in the testing pool.
The Mova App Experience
The app is functional and not flashy, which is what I want. You get scheduling, room-by-room cleaning selection, no-go zones, suction and water level controls, and a live map view. It's not as polished as the Roborock app — fewer animations, slightly less obvious where some settings live — but everything I needed was there within a tap or two.
Wi-Fi pairing was clean. Voice control through Alexa works. Notifications come through reliably when the bin needs emptying or a cycle finishes. No complaints worth flagging.
What I'd Change About the Dreame L40 Ultra Gen 2
- Add downward pad pressure. The single change that flips the verdict from Skip It to a possible Approval.
- Put the camera back. The Gen 2 stripped it out for no apparent reason.
- Include the solution tank. At this price tier, asking buyers to pay extra for it is awkward.
- Restore the dock dirt detect sensor. Another original Dreame L40 Ultra feature dropped.
None of these are unfixable. A Gen 3 with downward pressure, the camera back, and the solution tank included would be a completely different conversation.
Where the Dreame Lineup Still Earns a Buy
Same parent company, same price tier, materially different cleaning. The Mova Gen 2 has 12N downward pad pressure and 212°F hot water pad washing — both designed to actually scrub the floor. The Dreame just wipes. Buy the Mova.
Dreame L40 Ultra Gen 2 vs the Competition
Mova P10 Pro vs Mova V50
The Mova V50 is the step-up sibling. You get better obstacle avoidance, quieter operation, and a slightly more refined app experience. If you're spending more time at home and the noise matters, or if your home has a lot of obstacle clutter, the V50 earns the upgrade. For most homes, the Mova P10 Pro hits the sweet spot.
Dreame L40 Ultra Gen 2 vs Dreame L40s Ultra
Step up if you want to stay in the Dreame ecosystem. The Dreame L40s Ultra is the right L40-series buy — better reach, more modern dock features, real mopping performance. A small price step that delivers a noticeably better robot.
Dreame L40 Ultra Gen 2 vs original Dreame L40 Ultra
The original had the camera, the solution tank, and the dock dirt detect sensor — features the Gen 2 stripped out. The original Dreame L40 Ultra had its own reliability problems (mop pad reinstall) but the feature set was meaningfully better. Neither is the right buy today; both lose to the Mova P10 Pro Ultra.
