What customers like about LEFANT N1R

  • Ultra-slim design fits beneath furniture, beds and sofas.
  • Excellent battery life of up to 165 minutes.
  • A brushless direct suction inlet prevents tangles and works effectively on hair and fur.
  • Smart app is easy to configure and supports app and voice-assistant control.
  • FreeMove anti-collision sensors reduce mechanical impacts.

What customers don't like about LEFANT N1R

  • Random navigation does not map the room or follow a planned route.
  • Limited sensors can lead to frequent sticking, according to some users.
  • Limited suction is unsuitable for heavy dirt or thick carpets.
  • The housing material scratches easily.

Verdict

The Lefant N1R is a compact robot vacuum measuring 28x28x7.9 cm and featuring an elegant AG-etched frosted tempered glass top cover. It delivers a powerful 4500Pa of suction across 4 adjustable speeds and utilizes a brushless suction port design specifically engineered to prevent pet hair tangling. Main advantages include a large 560ml dustbin that holds up to 10 days of debris, seamless under-furniture navigation due to its slim profile, and full compatibility with smart apps and voice assistants. However, potential drawbacks include occasional Wi-Fi connectivity stability issues and diminished navigation accuracy on darker flooring surfaces or intricate room layouts.
