Detailed Differences

1. Capacity and Efficiency

Series 6 models generally offer a higher maximum load capacity (up to 10kg) and better energy efficiency (typically Class A), compared to Series 4 (up to 9kg, some models Class C).

2. Smart Technology

Series 6 offers Home Connect, allowing you to control and monitor your washing machine via a smartphone app. This is not available in Series 4 models.

3. Stain Removal

The Anti-Stain function, which automatically adjusts settings to tackle common stains, is available on Series 6 but not on Series 4.

4. Auto Detergent Dosing

Some Series 6 models feature i-DOS, Bosch’s automatic detergent dosing system, for optimal detergent use and convenience. Series 4 does not have this feature.

5. Noise and Drum Size

Series 6 machines are generally quieter during spin cycles and have a slightly larger drum volume, making them better suited for larger households or those sensitive to noise.

6. Program Variety

Both series offer a wide range of programs, including quick wash and steam functions, but Series 6 typically includes more advanced or specialised cycles (20 programs vs. 16–20 in Series 4).

7. Price

Series 6 models tend to be priced higher due to the additional features, improved efficiency, and smart connectivity.

Summary

  • Choose Series 4 if you want a reliable, efficient washing machine with essential features, steam function, and good performance at a lower price point.
  • Choose Series 6 if you want more advanced stain removal, smart home connectivity, auto detergent dosing, quieter operation, and higher efficiency, and are willing to pay a bit more for these enhancements.

Both series share core Bosch technologies like EcoSilence Drive, ActiveWater Plus, and SpeedPerfect, ensuring high-quality washing performance across the range.
