I love my vis nav robot. It does much better on carpet than my shark powerdetect. Either one will most likely perform better on carpet than most of the competitors. I would keep whatever one you prefer. I would expect overall the vis nav to be better and receive more updates over the heurist due to its age. The only gripe I have with the vis nav is it doesn’t like floor vents! More on reddit.com

Finally , someone’s down a tear down of this machine. Well done. I have one that started doing donuts as the left track moves around to freely. Can you suggest a fix please. More on reddit.com

This seems quite easy to do. At least it's not glued like it's on the V8. More on reddit.com

I mean, because it's from Dyson you'd figure that it has lots of significant improvement over are the robot vacuum cleaners... But it kinda doesn't. If anything I would even argue that because of its height it's Limited in a lot of ways (furniture and such). I definitely considered it, but I ended up going with a roborock S5 max. Basically because I think it might have had a higher runtime. Don't remember how well the suction was when comparing the two, but it was pretty similar i think. Yeah the roborock doesn't suck for the full width of the machine like the Dyson, but honestly it picks up what I throw it at it. Haven't had a problem on this department. I also think the app might have been a lot more advanced than the Dyson app. the s5 max can also mop the floor. Although I will admit, depending on your floor type it might leave a bit of dried water lines behind. We have three different types of tiles in my building, and on one of them the lines are very noticeable but on the others it's fine. and honestly one of the major differences is the fact that the roborock S5 Max users lidar instead of camera based navigation. Which means that it doesn't need to use an LED to light up the room if the lights are off. More on reddit.com
