The Dreame L40s Pro Ultra is currently considered one of the best value-for-money packages among robot vacuums in 2025. Can it compete with the much more expensive Ecovacs Deebot X9 Pro Omni?
Dreame L40s Pro Ultra vs. ECOVACS DEEBOT X9 PRO Omni: Who vacuums and mops better?
In 2024, robot vacuums are at an impressively high technical level. I tested both the Dreame L40s Pro Ultra and the ECOVACS DEEBOT X9 PRO Omni for several weeks in everyday use, focusing on suction performance, mopping performance, navigation, and operation. Both models are flagships of their brands, but there are relevant differences in detail. In this article, I'll show you which device is worthwhile for which household and where the strengths and weaknesses lie.
How do the two robot vacuums differ at a glance?
Both models offer impressive equipment, but they set different priorities. The Dreame L40s Pro Ultra brings more power when vacuuming, scores with a versatile cleaning station and particularly strong corner cleaning. The ECOVACS DEEBOT X9 PRO Omni, on the other hand, appears more compact, offers greater battery capacity and convinces with its mopping technology on large surfaces.

How do these differences affect cleaning in everyday life?
In my practice, the Dreame L40s Pro Ultra shows itself as a real powerhouse: Stubborn dirt and pet hair disappear reliably, especially in corners and on carpets. The higher suction power is noticeable on thick carpets. The cleaning station offers more comfort because larger tanks for fresh and waste water rarely need to be changed. Anyone with many corners, edges and winding rooms benefits from the better navigation and corner cleaning.
In contrast, the ECOVACS DEEBOT X9 PRO Omni scores points on large, open surfaces. Thanks to the larger battery and lower consumption, it is suitable for larger apartments without having to recharge in between. The mopping performance on surfaces is very decent – however, it struggles with heavily soiled edges. In addition, the noise level is a plus in everyday life, for example when you let the robot run while you work or make phone calls.
My practical tip: Anyone with many pets or small children will appreciate the stronger corner cleaning and suction power of the Dreame. For sensitive ears or large surfaces, ECOVACS scores points.
For whom is which model the better choice?
- Dreame L40s Pro Ultra: Ideal for households with many carpets, pets and winding rooms. Also for regular, stubborn dirt and when comfort through a large cleaning station is important.
- ECOVACS DEEBOT X9 PRO Omni: Recommended for large, open apartments when quiet operation and long battery life are in the foreground – and corner cleaning is not a top priority.
In terms of price, the Dreame is more attractive, the ECOVACS offers a bit more battery life and is quieter. Personally, I clearly tend toward the Dreame for families and pet owners, toward the ECOVACS for minimally furnished apartments with lots of space.
