Verdict

The Lefant LS1 is a compact robot vacuum measuring 32 x 32 x 9.4 cm, powered by a 4000mAh lithium iron phosphate battery that delivers a 3200Pa suction capacity and up to 150 minutes of runtime over a 200 square meter area. Its primary characteristics include precision LDS Lidar navigation, FreeMove 3.0 multi-sensor technology for 720-degree obstacle recognition, a 520ml dustbin, a double brush system with a floating silicon roller, and automatic carpet pressurization. Main pros include its highly efficient real-time 2D mapping with customizable no-go zones via app or voice control, a durable brushless motor operating at a quiet 60 decibels, and its slim body that easily navigates narrow furniture gaps. However, prominent cons include a tendency for the app's saved maps to occasionally reset and require a restart of the cleaning process, along with connectivity restricted solely to 2.4GHz Wi-Fi networks.

What customers like about LEFANT LS1?

  • Excellent LiDAR navigation that maps your home accurately and allows you to select specific rooms.
  • Very quiet operation, letting you speak or sleep undisturbed while it vacuums.
  • Thanks to its slim design (less than 10 cm tall), it easily fits under most furniture.
  • Strong suction power of 3500 Pa with rubber/silicone brushes that prevent floor scratches.
  • User-friendly app with advanced features, such as scheduling and manual control (joystick function).
  • Good battery life and automatically returns to the charging dock when low.

What customers dislike about LEFANT LS1?

  • Lacks a 'self-emptying' station, requiring you to manually empty the small dustbin regularly.
  • Less effective on high-pile carpets compared to pricier premium models.
  • The dustbin is relatively compact, which may be inconvenient in larger homes or with multiple pets.
  • Occasionally struggles to detect small dark obstacles or floor cables.
