Roborock S7 MaxV Plus refuses to enter area within open-plan spaceSohail06/16/2023 17:37 375 3 0

I recently purchased a Roborock S7 MaxV Plus to clean a large (400 square meter) open-plan carpetted hall with very few obstacles (only the occasional pillar). The vacuum works perfectly, except that it refuses to enter the black circle below:

Any ideas?

Note that it treats the edge of the circle as a wall, despite there being no obstacle there - it's just the same carpet. I've tried:

• initial quick-map
• full clean (with invisible walls to force it near the circle, as you can see above)
• spot clean
• pin and go
• zone clean (with a zone around the circle)

During any of these, the vacuum not only refuses to enter, but it actually get confused near the edge, and starts swirling around.

I've even manually remote controlled it to force it to enter the circle, but it starts going backwards (despite me pressing the forward arrow) when it gets to the edge. Once, I managed to get inside the circle, but the roborock then got so confused, I couldn't get it out again because it thought it was stuck from all sides.

I can get the lidar to manually map most of the inside of the circle, using pin-and-go and remote control to get it to travel around the edge, but look inwards. But that doesn't help it to enter.

There is nothing stuck to the vacuum to cause this, and it works flawlessly in the rest of the hall.

On further research, I assumed it was a magnetic problem BUT,

* I tested the magetism inside and outside the circle, and it was no different (about 50uT)

* I read that the S7 models don't even have this problem, since they don't have the magnetic sensor
