Our Verdict
Dreame L40 Ultra
Dreame X50 Ultra
The Dreame X50 Ultra is an upgrade over the Dreame L40 Ultra. The X50's cleaning performance is slightly improved over the L40's, but the X50's obstacle avoidance is quite a bit better. The X50's excellent low height clearance and threshold clearance represent huge leaps forward for Dreame over the L40 Ultra.
