You can't switch on spot cleaning while cleaning is in progress. During cleaning, the "Spot" button becomes the "Base" button; pressing it causes the VR300 to return to the base station. Before you can activate spot cleaning mode, you have to cancel the current cleaning program. Afterwards, press "Spot" followed by the green Start button to switch on spot cleaning mode.
Why does my VR300 go back to the base station when I just pressed the Spot Cleaning button?
