R7070 return to base limits

So my r7070 has not been able to find its base to charge.  I moved the base to center of house not in corner...... still not finding it.  Well it turns out that on page 13 of the manual it says the base must be within 16.4 feet lineally.  This means if your home is more than 34 feet long your bot may not find its way back.
