If you assume all robot vacuums are basically the same with docks that just look bigger every year, the Dreame L40 Ultra Gen 2 is a bit of a rude awakening. This thing doesn’t just park itself; it scrubs, rinses, dries, empties, refills, and actively tries to reach into corners most bots literally circle around.
We’ve been testing it in two very different environments: a 1,900 sq ft apartment with mostly hardwood and a large rug, and a 2,400 sq ft house with a mix of low-pile carpet, tile, kids, and two shedding dogs. Across both, the L40 Ultra Gen 2 consistently behaves more like a cleaning system than a simple robot vacuum.
## Design, Dock, and Build
The L40 Ultra Gen 2 looks familiar if you’ve seen recent high-end Dreame or Roborock robots: a round robot with a raised LiDAR turret and a hefty all‑in‑one dock. What’s different is how much Dreame has packed into a dock at this price.
- Self-emptying dust bin
- Clean and dirty water tanks for mopping
- Mop pad washing with hot-air
