Reviews last updated: July 2026 · How we calculate this

What customers like about Cecotec Conga 8490 Ultimate

  • High 7000 Pa suction power that performs well on carpets and deep corners
  • Effective laser navigation that creates accurate home maps and supports restricted zones
  • Interchangeable silicone central brush that successfully prevents pet hair tangles
  • Long battery runtime of up to 170 minutes suitable for large homes
  • Convenient 4-in-1 multi-functionality that sweeps, vacuums, mops, and scrubs simultaneously
  • Self-emptying base capability which allows hands-free dustbin maintenance for days
  • Highly functional and simple smartphone application with broad customization options

What customers don't like about Cecotec Conga 8490 Ultimate

  • Mopping/scrubbing performance is basic and can occasionally leave water streaks on floors
  • Physical hardware cannot fit under very low furniture due to the raised laser turret design
  • App pairing or initial Wi-Fi configuration can be occasionally finicky for less technical users

Verdict

The Cecotec Conga 8490 Ultimate is a 4-in-1 robot vacuum that sweeps, vacuums, mops, and scrubs, utilizing advanced LiDAR laser navigation to map and plan customized multi-floor routes via its App 3.0 or voice control. Its core strengths lie in an ultra-high suction power of 7000 Pa, a specialized anti-tangle silicone central brush for pet hair, a scrubbing mopping system, and a 3200 mAh battery providing up to 170 minutes of runtime to cover up to 170 m², alongside a 2.5-liter self-emptying base for hands-free convenience. However, its downsides include a 100 mm height that may prevent it from fitting under very low-clearance furniture, the reliance on a single side brush, and restricted Wi-Fi compatibility limited strictly to 2.4 GHz networks.
