Question about iRobot 5900 Scooba Robotic Wet/Dry Vacuum

4 Answers

My scooba is not picking up all the water.

Shouldn't the floor be left dry.  i just got this not too long ago, but i understood that it would dry also.  could it be that the squeegee thing isn't attached quite right or that it needs replaced.  it wasn't brand new when i got it.

    My rather new Scooba started leaving water and dirt on the floor. I ordered and installed the brush/filter/squeegee replacement kit and it improved somewhat. Now, it's just pushing the dirt around and picking up some dirty water but leaving the floor quite wet. The small mesh filter comes out completely clean and dry, leading me to believe some vacuum mechanism may not be operating. When doing a thourough cleaning and shaking of the tank today, I found much debris and hair stuck above the outlet inside the dirty tank.

    Help. My love of my Scooba is turning to frustration. The entire house is tiled.

    The entire tank of water is left on the floor after the cleaner is finished running. Since I need to mop up the water with many towels, it really isn't saving me time in the cleaning process. Plus I now need to wash all of those towels when I'm done.

    I love my Scooba when it works right.

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 Scoobe 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. hope this helps

    I havent used my scooba in over a year due to this. Out of a last ditch effort I looked it up the problem here to see if anyone else had this issue...... and shaking it really worked! I think I am going to make this a part of my routine when I clean it. Thank you so much!

I saw somewhere a solution about Scooba not picking up dirty water. I saw the user recommended cleaning Scooba orifices with a little thing called TurboSnake which is cheap. I used it and omg, I removed a lot of gunk from inside. It was clogging the system for sure.
I noticed now my Scooba gets really dirty water in the dirty tank!!!
Whoever posted that suggestion, thank you so much

After running for a normal cleaning cycle only about 1/3 of the water from the clean water tank has been moved to the dirty water tank.

this is by design. not all the water from the clean water tank will end up in the dirty tank, some is left on the floor, some evaporates.

My Scooba floor cleaner "check tank" light stays on even after it's refilled and everything cleaned but still will not work. It just keeps beeping at me when I try to start it. How do I reset it or get...

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.

Scooba says check tank and won't move.

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.

IRobot 5800 Scooba Vacuum dirt not going into the fliter basket

You can try rinsing the tank very thoroughly with warm water. Be very sure that you rinse the four ports on the underside of the tank (one round, two oval, one curved like Scooba's filter) very thoroughly, because all the dirt and dirty water moves through those openings and can clog things up.

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.
