Condensation inside SPRK+
Moisture inside SPRK+ can be noticeable for a short time during the second half of the charging cycle, or sometimes during heavy use. The heat inside the robot combined with a cold outside environment results in water droplets condensing as a result of natural humidity trapped inside. The condensation disappears once the temperature inside approaches the temperature outside of the robot.
Condensation inside of SPRK+ poses no safety or failure issue, nor has it affected the performance of the robot during our extensive testing. Wheel slippage may occur in extreme cases when moisture inside collects and the wheels hit it just right.
