Step 6

  • Remove the rubber end cap indicated by the red circle.
  • This step is not needed for a replacement. However, it is important for maintenance. Hair will build up in this area over time, and will cause error messages to pop up, as well as stopping the R75 from cleaning and moving.
  • Inspect this component at least every six months. This time may be less if you have animals.

What is the motor part that is being replaced?

I have a different question.

My ion 75 will clean for three minutes, and then it returns to dock. I have cleaned everything underneath but have not unscrewed anything. Popped the wheels and brushes and used Qtip on the side sensors. I charged directly from the wall (bypassing the charger) and had the same result….. three minutes cleaning and returns to dock.

Am I being premature to suspect a battery replacement is needed? This detailed article of yours has me wondering.

My ion RV870 series just stopped working flashes blue max. I have checked all components and cleaned. It has a good charge. I see no dysfunction what so ever. How do I get it working again?? I’m out of ideas because everything seems to be functional and clean.
