Lefant vs iMartine Key Specs
Cleaning capabilities
The iMartine BR151 offers a 2-in-1 vacuum and mop combo, featuring a 200ml dustbin and a 230ml water tank with two-level water control. This allows simultaneous mopping and vacuuming on hard floors. In contrast, the Lefant M210 is a vacuum-only unit. It lacks any mopping hardware, focusing solely on picking up dust, crumbs, and pet hair. If you need to mop hard surfaces after vacuuming, the iMartine handles both tasks in one pass. The Lefant requires a separate mopping solution or device for wet cleaning, making the iMartine the more versatile choice for mixed floor types.
Runtime and battery
Battery life is a key factor for larger homes. The Lefant M210 boasts up to 120 minutes of runtime, though this figure is measured in low suction mode. It uses lithium iron phosphate batteries for longevity. The iMartine BR151 provides up to 100 minutes of runtime, which varies depending on the selected cleaning mode and suction strength. Both units automatically return to their charging docks when the battery is low. The Lefant offers a longer potential cleaning session, which is beneficial if you have a large area to cover without interruption. The iMartine still provides ample time for most standard apartment or house cleaning cycles.
Size and clearance
Both robots are designed to fit under furniture, but their dimensions differ slightly. The Lefant M210 has an 11-inch diameter and a height of 2.8 inches. The iMartine BR151 is slightly wider at 11.8 inches in both width and length, with a height of 2.87 inches. The Lefant is also lighter, weighing 4.85 pounds compared to the iMartine’s 7.69 pounds. While both are slim, the Lefant’s smaller footprint may allow it to slide into tighter spaces under low-clearance sofas or beds more easily. The iMartine is still compact but slightly bulkier overall.
Navigation and sensors
Obstacle avoidance helps prevent the robot from getting stuck. The Lefant M210 features upgraded FreeMove Technology 3.0 with 6D built-in anti-collision infrared sensors. These help detect probable stuck areas and adjust the cleaning path automatically. The iMartine BR151 uses infrared sensors combined with mechanical obstacle detection. It also has a 15mm climbing ability and can handle slopes under 15 degrees. The Lefant’s specific mention of 6D sensors suggests a more detailed mapping of its immediate surroundings. The iMartine adds mechanical detection, which may help with physical barriers. Both rely on infrared technology for basic navigation.
Cleaning modes
You can choose from different cleaning patterns based on your needs. The Lefant M210 offers six clean modes: zigzag, random, spot, edge, scheduled, and manual control. It allows you to switch modes and power levels via the app. The iMartine BR151 provides four modes: Auto, Spot, Edge, and Zig-zag. Both support scheduled cleaning and app control. The Lefant includes random and manual modes in addition to the standard patterns, giving you more flexibility in how the robot covers the floor. The iMartine focuses on the most common patterns. If you prefer a wider variety of cleaning strategies, the Lefant provides more options.
Which robot vacuum fits your home
You have hard floors and want mopping
The iMartine BR151 includes a 230ml water tank with two-level control. It vacuums and mops simultaneously. This 2-in-1 design handles sticky messes on tile or hardwood. You get efficient whole-home cleaning in one pass. The Lefant M210 lacks mopping capabilities. If you need wet cleaning, the iMartine is the practical choice for your floor types.
You need long runtime on low suction
The Lefant M210 offers up to 120 minutes of runtime. This measurement is in low suction mode. It uses a lithium iron phosphate battery for longevity. The iMartine BR151 runs for 100 minutes. If you have a larger area to cover, the Lefant provides extra time. You can schedule it to clean while you are away without worrying about battery life.
You have pets and worry about hair
The Lefant M210 features a unique brushless suction port. This design prevents pet hair from tangling. It works well with families that have pets. The strong digital motor pulls dirt and hair into the dustbin easily. The iMartine BR151 does not specify a hair-tangle-free design. If pet hair is your main concern, the Lefant structure helps maintain consistent performance.
