Rinse the four ports on the underside of the tank with warm water, particularly the round opening that covers your Scooba's vacuum port and the curved one that matches the filter. Odds are, there's a clog in there and your Scooba knows it. Rinse the two oval ports as well, as thoroughly as you can.

Also, try priming the pump with water. The iRobot website shows how to do this under the Scooba troubleshooting section.

Then run the unit with water and vinegar (in place of the Clorox Cleaning Solution) if possible.

Scooba won't turn on


It sounds like you've got a finicky power button. Not a lot that can be done about that, but you may want to try getting your hands on the old-style Roomba remote, the black one. The power button from that will power on a Scooba, though you can't start a cleaning cycle that way. This might allow you to bypass the Scooba's power button altogether.

I cant open my scooba


If you haven't used the scooba before or if it has been a long time, the pump may need to be primed.  Go to irobot and do a search for how to do this.  I also had difficulty opening my scooba.  Press down with the palm of your hand on the back silver plate as you push down on the silver release handle.  This worked for me.

Scooba in diagnostic mode


This is a common issue :)
his morning, I turned on my Scooba and it started beeping a scale of tones and blinking all its lights in sequence. After an hour or so of resetting, cleaning, disassembling, researching, and scratching my head, I stumbled across the solution on Roomba Review. But, for me at least, it was even easier than all of that. I don't have any of my own pictures for this procedure, but it's pretty straight forward.
  • Remove the battery and power.
  • Remove the two screws holding the bumper shell in place and remove it.
  • Carefully peel up the sticker with the control buttons on it. This sticker is actually the control panel. There is a data cable attached to it just below the "Clean" button. Be careful not to break it!
  • Clean the surface under the sticker with some isopropyl alcohol. (I didn't actually have to do this, but I'm sure it doesn't hurt.)
  • Gently replace the "sticker" (i.e. control panel) and make sure it's completely flat.
  • Check to see if it works again. If not, repeat.
  • Replace the bumper shell and screws....
thnx.

Scooba not picking up dirt


I have had the same problem for six months and finally found the solution.

The problem is that the air duct into the dirty water tank was blocked. The air flows up the black removeable hose, into the dirty water tank and out through the filter. With the air duct into the dirty water tank blocked, no dirt gets anywhere near the filter.

The black removeable hose is the hose in the base of Scooba that the instructions tell the user to clean after each use. Despite cleaning this hose after each use, plenty of cat hair and other dirt passed by the hose and got lodged above it on the tank side of the incoming air duct.

The air duct into the dirty water tank is formed out of the blue plastic the tank is made from. You can find it by looking to see where the black removeable hose lines up with the tank when it is placed on Scooba. It is the same diameter is a the removeable black hose so you can't miss it.

Getting the gunk out is tricky because there is a bend in the duct. I fished most of it out with my fingers and then poked a bendable plastic spoon handle to get further down the duct. I then flushed water down it and shook the tank to get more out. After cleaning, water dripped into the air vent would come out the dirty water tank drain hole with little resistance.

After cleaning the air intake duct I ran my Scooba and got dirt in the filter for the first time in months.

Stuck on check tank indicator


If your Scooba's Green Check Tank light is coming on immediately on startup, please try the following steps:

1. Remove and reseat Scooba's battery, ensuring that you hear it click into place.
2. Remove and reseat the brush head
3. Remove and reseat the vacuum port and filter. When replacing the filter, be sure to press firmly into the hole. There is a magnet on the filter that must connect with the magnet on the Scooba.
4. Fill Scooba’s Clean Tank with approximately 1 cup of cold water, shake vigorously, and empty it to remove any debris in the tank.
5. Empty the Dirty Tank, refill with water, and slosh it around to pick up any sediment. Empty the Dirty Tank again.
6. Refill Scooba’s Clean Tank with water, adding a pinch or two of table salt. Run the Scooba. If the issue persists, please follow the steps below:

With the tank removed, press the Power button and then the Clean button.

If the robot tries to start a cleaning cycle, power off the robot and repeat, pressing the Power button first and then the Clean button. If the pump makes a “whirring” or squirting sound and the robot does not start a cleaning cycle (Check Tank indicator will light), this indicates that the pump is working. Replace the tank and try starting a new cleaning cycle with the tank on.

If Scooba does begin a cleaning cycle the second time you press the Power and then the Clean button with the tank removed, the pump valve could be blocked with debris. Using a turkey baster, straw or sports bottle, force water through Scooba’s solution valve. Confirm that the baster, straw or sports bottle fits snugly over Scooba’s solution valve, push water through the system at least three times, and then try re-starting Scooba.

Below is a link to a diagram of these steps for visual reference:

Scooba 5800 Power button Red Blinking


You probably have the manual, but here's the link to the Scooba 5800 manual anyway - just in case this would be useful to you: --> http://www.irobot.com/images/homesupport/5800_Scooba_Manual.pdf You could use a voltmeter to check the battery, but only a few months use shouldn't be enough to wear it out. If you don't have a load-tester to verify the battery's load-capacity, then you can check the voltage drop. (Assuming you can get it to contact the Scooba's circuits.) To do this, just check the battery voltage, apply a load by inserting it in the machine and turning it on, then check the battery voltage again. An excessive drop in voltage may indicate the battery needs replacing. However, the red blinking light is Scooba's indicator that it doesn't detect the battery at all. The first thing to do in this case is to clean the electrical contacts on the battery and in the Scooba. Use a damp cloth and a bit of toothpaste to rub the contacts clean on the battery and in the machine. (Toothpaste has mild abrasives in it and will clean the electric contacts without damaging them.) Make sure that both the battery and the Scooba are clean and dry before re-inserting the battery. Also, if the electric contacts in the machine are flexible matal tabs then verify that the tabs are standing up high enough to make good contact with the battery contacts. Hopefully the battery just needs it's contacts cleaned for your unit to work, but test the battery if you are sure that they are clean and seated properly to the contacts in the machine. If the battery appears to be failing, then contact www.irobot.com to cheack and see if they are still covered under your machine's warranty. Hope this helps! :)
