Chosen Solution
It starts working perfectly but after around 3 or 4 minutes the suction becomes weak and it shuts off with a motor overheat indicator. The motor part feels hot, the battery is fine though and doesn’t feel warm at all. I’ve checked the suction path for debris and there’s nothing in there, I can see right the way through all of the pipes, the filters are freshly washed and dried as well.
If your Shark vacuum is no longer picking up dust and debris, see the Shark ION Robot R75 Is Not Collecting Debris problem page for possible causes and solutions.
