Same family, same core hardware, slightly different priorities. The X50 Ultra runs longer, covers more ground per charge, washes its mop pads at a hotter temperature, and sits lower to the floor for getting under furniture, so it suits big homes with lots of low-clearance obstacles. The L50 Ultra matches it on brushes, mopping system, navigation sensors and smart home support for less money, making it the easier pick for average-sized homes.
Put the spec sheets for these two Dreame models side by side and the differences almost disappear. Both use dual spinning mop pads, a dual rubber and bristle brush setup, LiDAR paired with a camera, and the same AI plus 3D structured light obstacle avoidance. Both empty their own dustbins, wash and dry their own mops, and answer to Alexa, Google, Siri, and Dreame's built-in voice assistant. So the real decision comes down to a handful of numbers: 500 Pa of suction, 20 minutes of runtime, a fraction of an inch of robot height, and the gap in price between them.

These two rate close together, with the L50 Ultra at 8.4 overall and the X50 Ultra at 8.2, so the choice comes down to what you care about most. The L50 Ultra pulls ahead on cleaning, 8.4 to 7.8, meaning it does a better job on everyday dirt and embedded debris. The X50 Ultra answers with a 9.1 navigation rating against 8.2, so it maps smarter and handles cluttered, multi-room homes with less fuss. Both land at 8.8 on features, and the L50 Ultra is the stronger buy for the money.
Battery and coverage are where the X50 Ultra puts real distance between them: 220 minutes of runtime and 2,208 square feet in a single pass, against 200 minutes and 2,002 square feet. That matters if your floor plan is large enough that a mid-clean recharge break becomes routine. Height is the other practical gap. At 3.5 inches, the X50 Ultra slides under sofas and bed frames that stop the 3.8-inch L50 Ultra. Suction runs 20,000 Pa versus 19,500 Pa, a difference you won't feel on the floor. Mop pad washing happens at 176 degrees on the X50 Ultra and 167 on the L50 Ultra, both hot enough to break down greasy residue. Everything else, brushes, mop design, sensors, dock automation, is shared.
Both use the same dual brush setup pairing rubber and bristle, which is what actually lifts debris off carpet, and suction sits at 20,000 Pa for the X50 Ultra against 19,500 Pa for the L50 Ultra. That 500 Pa gap is too small to notice in daily use, and the L50 Ultra's stronger 7.16 cleaning rating against 6.64 shows why Pa alone doesn't tell the story.
Both run dual spinning mop pads, the setup that actively scrubs floors with downward pressure rather than just dragging a damp cloth around. The X50 Ultra washes those pads at 176 degrees versus 167 degrees on the L50 Ultra, so it breaks down oily kitchen residue on the pads a bit more thoroughly between runs.
Pet hair handling is essentially identical here since both robots use the same dual rubber and bristle brush, and rubber is what keeps long hair from wrapping into a knot around the roller. The X50 Ultra's extra 500 Pa gives it a paper advantage on embedded hair in carpet pile.
This is a true tie on hardware: LiDAR for mapping, a camera for recognition, and AI combined with 3D structured light and an LED for spotting socks, cords, and pet accidents in the dark. In practice the X50 Ultra pulls ahead in real-world navigation performance, earning a 7.62 rating against 6.98.
Both docks empty the dustbin automatically and wash plus dry the mop pads, so weekly maintenance drops to refilling water and swapping the dust bag. The X50 Ultra's hotter 176 degree wash cycle is the only functional difference in the base.
The X50 Ultra runs 220 minutes and covers 2,208 square feet per charge, compared with 200 minutes and 2,002 square feet on the L50 Ultra. Both robots return to the dock and resume automatically, but the X50 Ultra finishes a large single-floor plan in fewer interruptions.
There's nothing to separate them here. Both support built-in voice commands plus Alexa, Google Assistant, and Apple, and both handle no-go zones, multi-level maps for multi-story homes, smart carpet cleaning that boosts suction when it detects rugs, and smart obstacle avoidance.

There's no wrong answer here. The L50 Ultra gives you nearly the same machine for less, and it rates higher on the cleaning that matters most. The X50 Ultra earns its premium in bigger homes with tight furniture clearances and layouts that demand sharper navigation.
