Third-party reviews

Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What customers like about eufy 11S

  • Extremely quiet operation, allowing for conversation or TV watching while cleaning
  • Very slim profile (2.85 inches) allows it to clean under low furniture and beds
  • Strong suction power, especially on hard floors and low-pile carpets
  • Affordable price point, offering great value for money
  • Long battery life (up to 100 minutes) and automatic self-charging
  • Large, easy-to-empty dustbin

What customers don't like about eufy 11S

  • Random, 'bouncing' navigation pattern can be inefficient and miss spots
  • Lacks smart features such as Wi-Fi app connectivity, mapping, or voice control
  • Frequently gets stuck on cords, tassels, or thin rugs, requiring supervision
  • Struggles with hair tangling around the brushroll, requiring frequent manual maintenance
  • No boundary markers included, requiring physical barriers to keep it out of certain areas

Verdict

The eufy RoboVac 11S is a budget-friendly robotic vacuum featuring an ultra-slim 2.85-inch profile, a 0.6-litre dustbin, and a maximum suction power of 1300Pa. Main pros include its quiet 55dB operation, a 100-minute runtime per charge on its 2600mAh lithium-ion battery, a triple-filter system, and BoostIQ technology that automatically increases suction when transitioning from hard floors to low-pile carpets. However, significant cons include its reliance on inefficient, random bounce navigation instead of laser mapping, its lack of Wi-Fi or smartphone app compatibility, a 6-hour recharge time, and its inability to handle high-pile carpets.
