Dreame L20,L10 Ultra Water Filter

I have designed an adapter that allows a Filswa FW400 water filter to be used in the water tank of the Dreame L20 Ultra robot vacuum cleaner.
The filter ensures that the water is filtered before it is used for cleaning – this can reduce deposits in the tank and extend the device's lifespan.

The Filswa FW400 filter used is actually designed for coffee machines and replaces, among others:

• Siemens / Bosch EQ series (EQ3, EQ5, EQ6, EQ7, EQ9)
• De’Longhi ECAM, ETAM, EPAM, ESAM, BCO, EC series (replacement for DLSC002)
• compatible with Brita Intenza / TCZ7003 / TZ70003

This means the adapter can also be used for other projects where this filter type might fit.

Notes:

• The adapter is designed for 3D printing (e.g., from PETG or ABS, food-safe if possible).
• Please make sure to change the filter regularly (as recommended for coffee machines).
• Compatibility with water tanks other than the Dreame L20 Ultra has not been tested – minor adjustments to the model might be necessary.
• If you can successfully use the adapter in another tank, please leave a comment – I would be very interested!
• Also fits: Dreame L10 Ultra
• Compatible filters: Philips Aquafloow Filter
