    All filters and the squeegee have been cleaned, the dirty water tank has been half filled with hot water vinegar solution and shaken thoroughly. No seals appear to be out of place.

    I suspect this unit, which I bought used may have sat unused for a while - could some valves be stuck due to this?

    I have checked all of your suggestions and none of them seems to apply. DO you have any other suggestions?

Turn the tank over. It's transparent on the underside, and there are two oval-shaped openings that stick out more than an inch, located toward the middle. On the far right and far left sides, next to each oval opening, there is another opening. (These are oddly shaped-- one round, one large and curved like Roomba's filter.) Rinse all four of these openings really thoroughly with warm water. The water should go in one opening and come out one of the others. (This should happen when you put water in every one of the four ports.) Do not be surprised if you get clots of dirt out of there. This is generally what keeps Scooba from being able to pick up water. Then, if this works for you, make the tank rinse part of your regular cleaning routine and it shouldn't happen again.

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Hi,

There are only a few things that can cause the condition you describe. First would be to verify that the vacuum/blower motor is running. You can test this by placing your hand on the floor opposite the side where the charger is connected and see if you feel air movement. If no air is felt, there's your problem. Second, there is a valve located in the dirty tank that if blocked will prevent water pick-up. To resolve and clear this condition will require several processes to occur at once. Fill the dirty tank half way with hot water, add Scooba cup of vinegar. Close the stopper and shake the "Good Grief" out of the tank. This action is necessary and may have to be repeated several times to clear the flapper valve in the dirty tank. Third, there may be a poor seal between the tank and the Scooba base. Verify that both the left and right sides of the tank are close to the base and equal in distance. If the right side is farther away from the tank (larger gap) then water pick up will be poor. Some Scooba owners resort to using duct tape to hold down the tank. Fourth, verify that the thin rubber pieces on the bottom of the tank are not deformed and properly seated in the grooves.

Also, make sure that you should clean the Vacuum. Sometimes, they might be clogged with junk.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    It is possible that your robots vacuum is defective and therefore, not
    picking up the dirty water. Do you still hear that high pitched sound
    when your robot cleans? Do you feel air exhausting from the side of the
    tank?



    If you hear the vacuum and can feel the air, it is also possible that
    your robot tank is dirty and needs a good cleaning. You may want to
    have your tank soak in hot water and/or shake any debris out of it.



    If you flip the robots tank over, you have the holes for the Scooba
    filter port and vacuum port. You may want to insert hot water on one
    side of the tank (the filter hole) and come out of the other (the
    vacuum port hole).



    If you are not technically inclined, you may also consider our Scooba diagnostic and repair service.

    Let me know, if needed further assistance.

    Hope i helped you.

    Thanks for using ' Fixya ' and have a nice day!!

Hi .

Check the filter and check that the dust bin is well seated in place. Empty the dust bin.

If the motor is not working at all , then the motor is faulty. Motor fault is usually causing a three beeps fault code.

Check the filter holder and the blue rubber part in the dust bin. If this parts are worn, then the scooba may have lost sucking power.
In that case the solution is disassembling the unit , cleaning it , and replacing worn parts.

Flush out the solution valve with water (aka "prime the pump"). Use water, not just air, because water will clear any obstructions that may be in the lines. Also, rinse your tank through the four ports on the *underside*-- one round, two oval, one large and curved, all four in a row. Rinse them really thoroughly with warm water, then refill the tank and try the Scooba again. If it doesn't work, call us: 1-877-855-8593.

Scooba problem


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.
