Verdict

The Bosch Serie 4 Flexxo Gen2 BBH3K2801 is a 2-in-1 cordless stick vacuum featuring a 25.2V lithium-ion battery, an integrated handheld unit, and a 0.4-litre bagless dust container. Key advantages include a generous runtime of up to 55 minutes, convenient onboard accessory storage built directly into the handle, an LED-illuminated motorized floor nozzle, and a freestanding design that stores upright without a wall mount. However, major drawbacks include a lengthy 5-hour charge time, a relatively heavy weight of around 3 kg, and a small dustbin capacity that requires frequent emptying.
