Verdict

The Bosch BBH3ALL23 Flexxo Gen 2 is a 21.6-watt cordless 2-in-1 stick and handheld vacuum cleaner featuring a 23Vmax Lithium-Ion battery, a 0.4-litre bagless dust container, and an LED-illuminated AllFloor brush bar. Its main characteristics include an upright freestanding design, a RobustAir system for consistent performance as the bin fills, and integrated storage in the handle for its included XL crevice and furniture nozzles. Key advantages are its lightweight 3.0 kg frame, excellent maneuverability under furniture, a washable filter, and an impressive runtime of up to 50 minutes on its lower speed setting. However, notable drawbacks include a relatively loud 82 dB noise level, a lengthy 5-hour full recharge time, and a small dust capacity that requires frequent emptying.
