Compare the same measurement before judging the difference
X40 Ultra lists up to 12,000 Pa suction; L40 Ultra lists up to 11,000 Pa. Both are manufacturer laboratory maxima with actual results varying. These values are not an independent carpet-pickup comparison.
The maximum station wash-water outlet is 158°F (70°C) for X40 Ultra and 149°F (65°C) for L40 Ultra, each measured at about 73.4°F (23°C) ambient. Actual temperature varies; neither figure describes constant hot water on the floor. Both stations hot-air-dry the mops.

Shared carpet tools do not remove the carpet condition
Both models offer mop removal and a stated mop-lift difference of 0.4 in (10.5 mm); the checked guidance recommends avoidance for pile over 3 mm. L40 Ultra lists additional carpet strategies including Suction Boost, but that boost is unavailable in Quiet mode.
L40 Ultra’s up-to-4 cm (1.57 in) MopExtend reach describes access into gaps, and its side-brush clearance of 0.39 in (10 mm) describes a different component. X40 Ultra also lists MopExtend edge and low-furniture reach, but this comparison does not assign that same distance to it.

Compare exact accessories rather than assuming everything swaps
The named X40 Ultra / L40 Ultra Accessory Cleaning Kit is Confirmed for both US models. The separate regular mop-pad listing remains Unknown for each because it names series rather than the exact models. TriCut is sold separately on both checked robot listings. These findings do not establish universal part interchangeability.
