Verdict

The Bosch Serie 4 Flexxo BBH3ALL28 is a bagless, 2-in-1 cordless upright and detachable handheld vacuum cleaner powered by a 25.2V lithium-ion battery. It features a motorized AllFloor brush bar with integrated LED lighting, two power speed settings, a 0.4-litre easy-empty dust container, and an onboard accessory storage design holding an extendable crevice nozzle and a 2-in-1 furniture brush with an upholstery nozzle. Key advantages include a lightweight 3 kg freestanding body, a long runtime of up to 55 minutes, and a RobustAir system that ensures constant suction performance even as the bin fills up. However, notable drawbacks include a relatively small 0.4L bin capacity that requires frequent emptying, a long 5-hour charging time, and a loud 82 dB operational noise level.
