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.
