Scooba doesn't put watter. Pump not working?

try here > http://uksupport.irobot.com/app/ask you can email them with your question.

I had this problem and got the solution form i Robot customer service:
1. Put the Scooba on a solid surface
2. Press on the back of the tank on the IRobot logo
3. At the same time push down on the front switch

Good luck, it works for me.

Do you leave the battery on charge long enough? Try 4-hours up to overnight. If so, then the battery is probably at the end of it's useful life. Getting a new battery depends on cost versus life expectancy of the robot and whether it does the job you want it to do.

Does it put down clean water onto the floor? If so, rinse the four ports on the underside of the tank really thoroughly. You might have a clog; it's not difficult to dislodge it if you use enough warm water. Also make sure that the squeegees on the cleaning head cartridge (which holds the brush) are straight and in good condition.

If it doesn't put down water at all, try the tank rinse anyway, as it can help with that issue, too.

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.

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.

Press down on the silver tank saddle at the back of the robot. While putting pressure on the saddle, tap the release handle quickly, right at the edge. That should cause the tank to pop up.

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.

did you try priming the pump?

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.
