Who Should Buy Which Model?
It looks to us like Dreame has a little something for everybody, with the X40 being by far the most advanced model, albeit also the most expensive. Letโs find out who each of these Dreame robot vacuums is ideal for.
Dreame X40 Ultra
The Dreame X40 Ultra is by far the most advanced model in this lineup, taking the advanced features of the X30 to the next level. For those who are looking for the highest functionality and the most hands-free experience, the Dreame X40 Ultra is the model we recommend.

Dreame X30 Ultra
If youโre looking for a good balance between price and performance, the Dreame X30 might be right for you. It hits the mid-point between the X40 and L20 in regards to obstacle avoidance and suction power, but more notably, the X30 introduced many of the innovative features now found in the more recent, and pricier, X40. This means you can get a high-tech robot vacuum at a more affordable cost.
Surprisingly however, in our evaluations, the X30 Ultra didnโt perform as well in some areas as the L20, so be sure to check out that review to see which performance metrics are important to you.

Dreame L20 Ultra
For those looking for a reliable option, the Dreame L20 Ultra has demonstrated excellent performance in our studio tests. With a high-functioning dock for managing debris, water and washing its mop pads, many users have been happy that they have added the L20 to their cleaning arsenal.
That said, it is missing some of the more recent and advanced features that the later versions, the X30 and X40, have, like OmniDirt Detection and RoboSwing, along with a higher suction levels. Itโs a great option for those looking for a combination of affordability and functionality.
