Verdict

The Bosch Cosyy'y ProFamily BGLS4A444 is a corded, bagged cylinder vacuum cleaner equipped with a 700-watt motor, a 4.0-liter dust bag capacity, and a 10-meter operating radius. Its main characteristics include an UltraAllergy hygienic filter that traps 99.99% of fine allergens and a unique ToyGuard attachment to prevent small parts from entering the dust bag. Key pros include an exceptionally quiet operating noise of 69 dB(A) thanks to the SilenceSound System, manual power adjustment with the ComfortRegulator, and consistent suction performance via the PowerProtect system even as the bag fills. On the downside, the unit can feel slightly bulky or heavy at 5.8 kg, its plastic exterior is prone to surface scratching, and some users note that its high suction power can occasionally lift lightweight rugs, making it harder to maneuver.
