Lefant M330 Pro vs Lefant M310 Ultra
Quick take: The Lefant M330 Pro costs $50 less; the Lefant M310 Ultra runs longer per charge (170 vs 150 min).
Which one to buy
Home size is the question to answer before spending $50 more on the Lefant M310 Ultra. Neither robot has a self-empty dock or mop washing, both map with LiDAR, store multiple floors and use PSD obstacle avoidance that works in the dark. The step up is runtime and a published suction figure: the M310 Ultra runs 170 minutes against the M330 Pro's 150 and is rated at 6000 Pa, while Lefant states no Pa number for the M330 Pro.
The M330 Pro has the more convenient carpet handling. It boosts suction on rugs by itself and steers around carpet when mopping. The M310 Ultra avoids carpet while the mop holder is on, and you remove the holder to get full suction on rugs. The M330 Pro also lists a 450 ml bin; Lefant gives no bin or tank size for the M310 Ultra.
Both are now discontinued with no direct successor, and Lefant's current robot is the M2S Pro at $180. Between these two, for apartments and average-size homes, the Lefant M330 Pro was the smarter buy. Twenty extra minutes of battery only matters if a single charge doesn't already finish your floor plan, and the M310 Ultra's four manual cleaning patterns are a niche extra. The $50 step up made sense for a large single level or mostly carpet and the stronger rated suction.
Lefant M330 Pro
Best for an apartment or average-size home; it does the same mapping job for $50 less and handles rugs automatically; now discontinued, like the M310 Ultra.
Lefant M310 Ultra
Go this way if your home is large enough to need the longer 170-minute runtime or you want a rated 6000 Pa for carpet; now discontinued, with Lefant's M2S Pro as its current alternative.

Lefant M330 Pro vs Lefant M310 Ultra: common questions
Does the Lefant M310 Ultra empty itself?▾
No. Like the M330 Pro, it returns to a basic charging base and you empty the bin by hand. Neither model washes or lifts its mop pad either.
Which Lefant handles rugs better, the M330 Pro or the M310 Ultra?▾
The M330 Pro is more hands-off, boosting suction on rugs automatically. The M310 Ultra reaches full suction on carpet only after you take off the mop holder, though it carries a published 6000 Pa rating.
