20 Most Recent iRobot 5900 Scooba Robotic Wet/Dry Vacuum Questions & Answers

I calledthe company and they told me to forcefully flush warm water repeatedly through the valve that is just  above  the brush release button the the mechanical part  of the scooba.  It may take 20 or 30 flushes (I used a turkey baster, iRobot suggested a children's nasal syringe) and "Scooby" is  running great.

Clean off contacts. If this doesn't help and the machine is over 1 year long, it probably needs a new battery pack.

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

In order to troubleshoot, couple of things to check would be:
1. Do you have the charger terminal, or do you have the charger that you have to take out the battery and charge. Because I have found that the base terminal charger works better than the battery charger that needs the battery to be removed to charge. If you have the terminal charger and the power light is green when it is in the charger I would start from the terminal
2. Nicd and Lion batteries have this tendency. They work great for a year, and then slowly die off. When new, the device must be charged for 14hr nonstop, and then every 2-3 months run dead, and recharged again 14hrs nonstop. This is done so the CPU knows what empty battery and what full is. It does this by measuring the amount of current flowing thru a very precise resistance. If you do hit and miss charge cycles or leave it charging too long, it either develops a false memory of the above two conditions, or gets HOT and the electrolyte paste dries out. Fix is to wear it out, charge 14hrs, wear it out again and repeat 3-4x. Then recharge and use. If that doesn't fix it, the batteries are too dried and need to be replaced.
  1. It does sound like you might need a new battery, but the issue could also be the power button. I suggest giving us a call at customer services so that we can more accurately determine what the problem might be and how we can most efficiently help you to solve it.

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.

Remove all three wheels and make sure they're clean. Tap the bumper with your hand, and maybe blow out behind it with compressed air. If the problem continues, call us-- it's in the wheel motors, most likely. 1-877-855-8593.

Make sure that the filter is dry and properly installed. Usually that's what causes the "check brush" light.

iRobot 5900... | Answered on Sep 02, 2009

Prime Scooba's pump with water and rinse the four ports on the underside of the tank very, very thoroughly with warm water. That should take care of it.

Your speaker went out. It could be totally isolated. You're not going to be able to determine what's wrong with your Scooba if something does happen, though, because without those beep codes, there's no way for the robot to communicate with you.

If you're under warranty, call support at 1-877-855-8593 and let them know your speaker went out.

iRobot 5900... | Answered on Jul 07, 2009

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.
