Roborock S4 - almost useless on carpets. Please help!

Just replaced my Eufy G30 by Roborock S4 because of greater suction and sophisticated mapping. Did this even against advice from some reviews, online and on YouTube, that S4 behaves erratically even on low to medium pile carpets. I thought it may have been solved by firmware or in latest production runs. My living room, kitchen, bathrooms and corridors are all hardwood and tiles, but bedrooms are wall to wall carpeted with the usual low pile. S4 totally excelled on everything but the carpets, going fast in neat rows, taking with aplomb on obstacles and complex topography and so on. Never once stopped, got caught up in something or confused!

I was soooo happy. But then it reached the first carpeted bedroom, the one that more primitive and cheaper Eufy had no problem with, and total nightmare ensued. Instead of going about its business in neat rows S4 started to behave like it totally lost its mind - randomly stopping, rotating on the same spot as though there's an invisible obstacle, and then reversing back and continuously zigzagging back and forth. And worse - no less than a dozen times it would pause just for no apparent reason with an error that there's an obstacle or it got caught in something. But there would be nothing around, NADA! Just pushing Resume button in the Roborock App or on the device itself will be enough to make it going like nothing happened... only to get stuck again few minutes later. As a result it took 2x the time and battery to clean and map the bedroom that is 3x smaller than the hardwood living room.

Roborock Support, what's wrong with my S4? Is there a fix? I love the design, price, functionality and how it cleaned the non-carpeted portion of my house, but it's useless to me on carpets! What is solution here?

Thanks,

Alec

PS. I use Roborock app on Android. S4 firmware version is 01.03.58

  • Below is the reply from Roborock support on the Messenger Chat after they asked me to post a photo of my typical cheap and thin US apartment carpet: "We are afraid robot S4 could not cope with this kind of carpet well." So beware!

    @Klopus:

    By the way, unscrewing the side brush totally fixed the problem! Now S4 runs on a carpet like a champ. But what am I missing?

  • SAME! I just got mine today and have the same height of carpet and this thing looks like it's crazy! It's spinning around in circles almost like one side isn't being powered. For $400 and all the stellar reviews I expected more... I'll try the side brush trick, and if that doesn't help, back it goes!

  • Hello,

    Sorry for the trouble caused here.


    Could you send us a problematic cleanup map for reference?


    Also, please send us some pictures of the carpet you use.


    Try to uninstall the water tank and ensure that there is nothing stuck in the wheels.


    May I know where you purchased the S4?
