Best praise vs top criticism for Roborock S4
Best Praise
+2 pts“We had a roborock s4 that died was really solid, got a shark and found out how much better its roller was at not becoming a tangled mess. I was surprised at how little it got tangled despite the amount of cat hair it was picking up. The sharks software is unfortunately unusable and the vacuum is so quiet when it complains that I have to guess what's wrong. ”

+3 pts“My only faulty robot vacuum was a Roborock S6 which had constant bumper stuck/'error 2'. It rarely completed a run without restarting the run several times. When I looked into it there were so many people with the same issue. The worst part was that it was a common issue on the S4,S5,S6,S7 - four generations released without solving the issue. They eventually fixed it, but I wouldn't want another Roborock after seeing how they swept that issue under the rug and continued to release new models with the same problem. With that being said all models from all brands can have issues. Some are genuine issues and some are misunderstandings. The main thing is to buy from a store with a good return policy”
