Verdict

The Cecotec Conga Immortal ExtremeSuction 11.1V Hand is a lightweight, cordless handheld vacuum cleaner featuring ForceSonic technology with a maximum power of 75W and a suction capacity of up to 5.5 kPa. Utilizing bagless cyclonic technology and a Wet & Dry system, it efficiently handles both solids and liquids, storing them in a large 500 ml easy-empty tank while an anti-allergic system with a high-efficiency filter traps dust and mites. Powered by a 2200 mAh lithium-ion battery, its main pros include its versatile dual-cleaning capability, a comfortable ergonomic design weighing just 1.1 kg, quiet operation at 62 dB, and an unrestricted cordless range for home or car use. However, its primary cons are a relatively short runtime of up to 20 minutes and a lengthy battery recharge time of 4.5 hours.
