Our take on the Lefant M350 Max Robot Vacuum and Mop

The Lefant M350 Max is a robot vacuum and mop with a self-empty station that holds 2.2L dust bags, rated for up to 75 days of hands-free cleaning. It claims 10,000Pa suction, PSD obstacle avoidance and a grid-pattern cleaning routine, and its 11-inch round body is slim enough to slide under sofas and beds. It is controlled by app and Alexa, with scheduling, spot cleaning and no-go zones. Its price has been flat: $249.99 at Best Buy as of November 3, 2026, the only price seen since October 30, 2026, so there is no discount history to judge against.

Pros
  • Self-empty station with 2.2L bags cuts bin emptying to roughly every 75 days
  • High 10,000Pa suction rating for the price
  • Obstacle avoidance with no-go zones and stair detection
  • Slim body reaches under low furniture
  • App scheduling plus Alexa voice control
  • Works on hardwood, tile and carpet
Cons
  • Only one store lists it new, so price competition is limited
  • No price movement since tracking began, so no proven deal window
  • 1-year parts and 3-month labor warranty is short on labor
  • Mop function is basic; it is not a scrubbing or self-washing mop
  • Dust bags are a recurring consumable cost

Questions and answers

Is the Lefant M350 Max worth $249.99?
At $249.99 you get self-empty, strong claimed suction and app control, which is a lot for the money. The trade-offs are a basic mop and a short 3-month labor warranty.
How often do I have to empty it?
The 2.2L dust bag in the station is rated for up to 75 days of cleaning. Actual life depends on floor type, pet hair and how often it runs.
Does it really have 10,000Pa of suction?
That is Lefant's rated figure, and it is high for this class. Real pickup on carpet depends on the brush and how often you run it, so expect strong but not premium-brand performance.
Will it fit under my sofa?
The body is 11 inches across and described as low-profile, so it fits under many sofas and beds. Measure the gap under your furniture before buying, since exact height is not listed here.
What comes in the box?
Expect the robot, the self-empty station, a dust bag, a mop pad and a charging setup. Confirm the included accessory count on the Best Buy listing before ordering.
When is it cheapest?
It has held at $249.99 at Best Buy since at least October 30, 2026, with no lower price recorded. Watch for Black Friday and holiday sales, when robot vacuums usually see their deepest cuts.
Where is the Lefant M350 Max Robot Vacuum and Mop cheapest?
