Eufy RoboVac 11S: what works, what doesn't?
What works well
- Extremely flat: only 7.2 cm, fits under almost any sofa and bed
- Very quiet: 55 dB, quieter than a fridge, fine to have audible in the background
- BoostIQ automatic: detects carpet and dirty spots in 1.5 s
- Excellent value: a branded robot under €180
- 100 min battery life: enough for 80 to 100 m² in one run
- Robust build: typical of Anker, 5 to 7 years of life is usual
- Anti-drop sensors: reliably does not fall down stairs
Points of criticism
- No app, no Wi-Fi: can only be controlled by infrared remote
- No mapping: random pattern instead of systematic lanes, inefficient in large flats
- No mopping function: pure vacuum
- Filter not washable: filter change needed every 2 to 3 months (running costs)
- Weak on high pile: pushes instead of cleaning, long pet hair gets tangled

Build quality & everyday use
What carries the Eufy RoboVac 11S in everyday use: extremely flat (only 7.2 cm, fits under almost any sofa and bed) and very quiet (55 dB, quieter than a fridge, fine to have audible in the background). We have to be honest about the weaknesses: no app, no Wi-Fi. It can only be controlled by infrared remote.
If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.
