Lefant U180: what works, what doesn't?
What works well
- Genuine 2-in-1 function: vacuums and mops at the same time in one pass
- Very low height of 7.5 cm: goes under sofas, beds and low furniture
- Auto-boost to 3,200 Pa: automatically more power when it detects carpet
- 150 min runtime: enough for about 140 m² in one go
- 3-level water amount: by app, for wood/tiles/stone
- Alexa + Google + app: smart home integration included
- Very low entry price: budget hybrid in the 2-in-1 segment
Points of criticism
- No persistent map: random pattern / short-term mapping, no room memory
- No auto-resume: has to be restarted manually after recharging
- Passive mopping: damp cloth, no vibration, removes only light dust
- Small 160 ml water tank: enough for 60 to 80 m², refilling needed in larger flats
- Noise level 65 dB: at the upper end of the budget class

Build quality & everyday use
What carries the Lefant U180 in everyday use: Genuine 2-in-1 function (vacuums and mops at the same time in one pass) and Very low height of 7.5 cm (goes under sofas, beds and low furniture). We have to be honest about the weaknesses: no persistent map, a random pattern / short-term mapping, with no room memory.
