I haven't noticed anything so far. However, we could not use the installation set 1 to 1. We then found a solution with the washing machine (inlet & outlet), but only with one plumbing :) Not that anything is leaking. Otherwise we are very satisfied.

We've had it for about 5 months and the water is very chalky. So far no problems have been recognised.

I have been using the Dreame X50 for 3 months and so far we have had no problems with limescale, although we have installed a descaling system in the house, not least because of the Dreame X50.
