Question about iRobot 5800 Scooba Vacuum
Hi, I did check the voltage measurements as shown on my attached picture. I did check the power supply into the Scooba is 22V as the manual said. Step 1: it shows the battery is low (3V). Step 2: it shows the Temp. senor line is 5 V and already pumps into the battey, +/- ve terminals are almost 0V (not activated yet) Step 3: it shows the Temp. senor line dropped to 2.5V (means with load). the +/- ve terminals has slightly higher voltage that the battery. I don't know the charging voltage pattern of Scooba. (Supposes 14.4 V?) Even the Power button Blinking Red, I have monitored it for 12 hours and found the voltage of the battery is keeping growing up 10.00 V as it is only 3V at the beginning. Any advises on battery or Scooba, which one has problem? Any suggestions appreciated Thank you very much
As for which one has the problem, I would say it has to be the battery. Rechargeable batteries of all types are known to have similar characteristics, one of which is discharging the batteries to maintain good rechargeablility. At least one person has demonstrated this for the Scooba battery in the roombareview.com forums when he brought a "dead" battery back to life. He allowed the battery to slowly and completely discharge using a 12-volt automobile bulb, followed by recharging the battery on the Scooba external charger. This procedure brought his "dead" battery back to a full charge! However, other forum members have reported that many have experienced problems with Scooba battery life, and that as a consequence of this iRobot will replace your battery if you call them and report a short-life battery problem. You can contact iRobot at (800) 727-9077 if you would like to report a battery problem and request a replacement.
