Verdict

The Cecotec Conga ThunderBrush 820 is a 3-in-1 cordless vacuum cleaner featuring vertical, broom, and handheld capabilities powered by a 29.6 V lithium-ion battery and 130 W motor. Main characteristics include a bagless design with cyclonic technology, a high-efficiency HEPA cartridge filter, a 0.7-litre dust capacity, and an integrated motorized central brush. Notable pros are its ergonomic 360-degree balanced design for high surfaces, a relatively long runtime of up to 65 minutes on Eco mode, and an operating noise level capped at 78 dB. However, major cons include a substantial weight of 3.84 kg that can cause hand fatigue, a standard 4-to-5-hour recharge cycle, and reduced runtime on Turbo mode.
