Get This Deal

For just $399.99, below its 90-day average of $424.96. The M3 typically sits higher, so this is a solid window to grab one if you have been watching the price. The 30-day average sits at $318.70, while the 180-day average is $737.90, putting current pricing well inside a reasonable buy zone.

What You're Getting

The Lefant M3 combines a 12,000Pa suction motor with a self-emptying dock that holds an 8-week dustbin and 2.5L water tank. The station auto-washes mops at 113 degrees F and cools them dry to prevent warping. A built-in detergent dispenser keeps things fresh without manual refills.

Other specs worth knowing:

• Freemove Tech 3.0 obstacle avoidance navigates around furniture, cords, and shoes
• LiDAR laser mapping scans 360 degrees for accurate multi-floor maps (stores up to 3 floors)
• V-shaped dual-comb brush cuts and collects hair to prevent tangles
• 9mm mop lifting protects carpets -- switches between mop lift, turbo carpet, and vac+mop modes
• Slim 4-inch profile fits under low-clearance furniture

Who This Is For

Best for pet owners and busy households who want a vacuum that empties itself, washes its own mops, and doesn't get tangled in hair. The auto-refilling water tank and detergent dispenser mean you can go weeks without touching the station.

Skip this if you already own a capable robot vac with a self-cleaning dock -- the upgrade is worth it only if you need the mop washing and carpet detection features.

Final Verdict

The self-cleaning station and 12,000Pa suction make the $399.99 price easy to justify for anyone tired of emptying bins and hand-washing mop pads. Grab it if you want a hands-off cleaning setup that actually handles pet hair and carpets.
