I've had a Roborock S7 for the last 6 months and have absolutely loved it. Unfortunately, I've recently been hit with the dreaded Error 4 cliff sensor notification. I tried taping over the sensors (after reading some advice here) but that didn't see to do anything.
I then went on ebay and ordered some cliff sensor covers. These arrived today and were extremely difficult to fit. I used a hair dryer to help the plastic expand on the covers and managed to get them sorted. Unfortunately it doesn't seem to have made any difference what so ever.
I bought the vacuum on ebay and have contacted the seller (as Xiaomi sent me an email basically saying that they wouldn't help). I'm waiting for a response but I really doubt that they will help me.
So does anyone know anywhere in the UK (I'm based in London) where I can get the Roborock repaired? Two of the sensors look like they have managed to get water inside of them and I think it may be an issue that I can't fix. I've tried some google searches but can't really find anything promising.
Cheers for your help!
