Question about Bosch Hausgeräte BCS71HYG4

The main difference between the Bosch Unlimited 7 ProHygienic Aqua BKS71HYG1 and the Bosch BCS71HYG4 lies in the design and features. The BKS71HYG1 is a bagless combination vacuum cleaner with integrated suction and mopping function, three suction levels (Eco, Auto, Turbo) and an articulated suction tube for greater flexibility. It weighs over 5 kg and has a noise level of 82 dB. The dust container holds 0.3 litres and the water container 0.25 litres. The battery runs for up to 40 minutes, but only on the lowest suction setting.

The BCS71HYG4 is a lighter stick hoover (approx. 2.9 kg) with battery operation, also suitable for dry and wet cleaning, with a running time of 40 minutes and a noise level of 82 dB. Details on suction levels or mopping function are not explicitly mentioned, it is designed more as a classic stick hoover.

To summarise:

- BKS71HYG1: Combination vacuum cleaner with suction and wiping function, 3 suction levels, articulated tube, approx. 5 kg, 0.3 l dust container, 0.25 l water container, 82 dB, up to 40 min. running time (Eco)
- BCS71HYG4: lightweight stick hoover, approx. 2.9 kg, 40 min. running time, 82 dB, for dry and wet cleaning, no information on suction levels or wiping function

The BKS71HYG1 is therefore more extensively equipped and heavier, while the BCS71HYG4 is lighter and simpler in terms of features.
