How to choose
Multi-floor mapping matters most
A robot that cannot remember each floor must remap every time it moves upstairs. The LVKANGDA and the iMartine each store up to 5 floor maps, and the Lefant and MAMNV also create multi-floor maps. The LVKANGDA relocates when carried to a different floor, and the iMartine recognizes and switches between levels, so check the map count against the number of levels you clean.
Compare suction and runtime together
The iMartine has 18000 Pa, the LVKANGDA has 12000 Pa, the MAMNV has 11500 Pa and the Lefant has 6000 Pa. For runtime, the LVKANGDA and MAMNV each give 160 minutes and the Lefant gives 130 minutes. A higher Pa figure does not replace a long runtime on a large second floor.
Self-emptying and mopping upkeep
The iMartine base is bagless with a 1.3L dust cup, while the MAMNV base uses a 90-day capacity dust bag and the box includes 5 dust bags. The Lefant and LVKANGDA each use a 300ml water tank, and the MAMNV uses a 230ml water tank with a washable mop pad. Keep spare bags, filters and mop pads on hand so upkeep does not interrupt cleaning.
