Verdict

The Bosch Serie 4 Flexxo BCH3P255 is a versatile 2-in-1 cordless bagless vacuum cleaner featuring an integrated detachable handheld unit, a 25.2V Lithium-Ion battery, and a 0.4-liter dust capacity. Weighing 3.1 kg, this unit excels with an impressive maximum runtime of up to 55 minutes, two performance levels, a freestanding design, and uniquely onboard stored accessories like an extendable crevice tool and a 2-in-1 furniture brush. Main advantages include its highly maneuverable motorized AllFloor Power Brush, consistent suction courtesy of the RobustAir System, and exceptional convenience for floor-to-ceiling cleaning. However, notable drawbacks include a relatively long charging time of 4 to 5 hours, a small dustbin capacity that requires frequent emptying, a slightly plasticy build quality, and a non-replaceable battery.
