The most striking difference between the Lefant M210 and the MONSGA MS1 MAX lies in their navigation capabilities and overall cleaning efficiency. The Lefant M210 employs 'random' navigation, meaning it cleans by bumping around, potentially missing spots or repeating others. This translates to longer cleaning times and less thorough coverage, especially in complex layouts. In contrast, the MONSGA MS1 MAX utilizes advanced LiDAR navigation, enabling it to precisely map the home, plan efficient cleaning paths, and cover areas systematically. This results in quicker, more comprehensive cleaning and the ability to set no-go zones or select specific rooms for cleaning, offering a significant upgrade in daily convenience and floor cleanliness.

Another critical distinction is suction power and maintenance convenience. The MONSGA MS1 MAX boasts an impressive 6000Pa suction power, capable of tackling deeply embedded dirt and pet hair effectively on both hard floors and carpets. While the Lefant M210 is marketed for 'strong suction' and pet hair, it lacks a quantifiable suction power specification, making it difficult to compare directly, but it is unlikely to match the MONSGA's extreme capability. Furthermore, the MONSGA's 3.5L self-emptying station is a game-changer, eliminating the need for manual dustbin emptying for up to 60 days. The Lefant, on the other hand, requires regular manual emptying, a less convenient task that demands more user interaction.

The MONSGA expands its utility with an integrated mopping function, allowing it to vacuum and mop simultaneously, making it a true 2-in-1 solution for hard floors. However, a notable trade-off is the absence of an automatic mop lift for carpeted areas, requiring manual removal of the mop pad to prevent wetting carpets. It also features carpet detection and a longer 180-minute runtime, suitable for covering larger areas up to 2000 sq ft. The Lefant, while lacking mopping and carpet detection, possesses one distinct advantage: its ultra-slim 2.99-inch height. This design allows it to navigate under very low furniture where taller robots, including the MONSGA (which is implicitly taller with its LiDAR turret and mopping tank), cannot reach. This makes the Lefant suitable for specific niches, but overall, the MONSGA offers a more comprehensive and advanced cleaning package for a similar price point.
