Verdict

The Bosch BGS21X320 Serie 4 is a corded, bagless cylinder vacuum cleaner powered by a 550W motor backed by a 10-year motor guarantee, engineered to deliver constant high performance through Power AirCycle Technology and precise electronic power regulation. Featuring a 2.0-liter dust container, an operational radius of 10 meters with automatic cord rewind, and a double filtration system with a washable HEPA hygienic filter, it effectively maintains clean exhaust air with a operating noise level of 78 dB. Its main pros include an efficient EasyClean System for effortless dust box maintenance, compact hose storage that fits easily into standard cupboards, and a relatively lightweight build at 4.7 kg (cleaner only). On the downside, some users note that the combined crevice and upholstery accessory tool offers less separate versatility than traditional detached attachments, and its 78 dB noise level can be considered a bit loud by some compared to dedicated silent models.
