Lefant M310 Ultra

At just 9.7cm tall, the M310 Ultra squeezes under low furniture while delivering 6000Pa suction. It uses laser LiDAR navigation to avoid obstacles and map complex layouts accurately. The 180-minute runtime covers most home sizes without a recharge cycle, and the compact all-in-one mopping dock fits easily beside a toilet or in a small closet.

If your home has furniture that sits close to the floor, this model earns its place. The thin profile reaches under sofas and bed frames that other robots can't access. It's a smart pick for smaller homes or apartments where storage space is premium and under-furniture cleaning is a priority.
