Which should you buy?
The X40 Ultra is the clear pick on raw spec strength, leading by 24.1 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the X40 Ultra if you care most about suction and battery life. The biggest gaps in its favor are suction, battery life, water tank, among others.
The Robot Vacuum Pro similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable mopping, lidar, self-empty base, so those specs don't separate the two — focus on the differences below.
