Roomba Discovery wiggles back and forth and turns over and over
My 8 month old Roomba Discovery has just started moving forward and "wiggling" back and forth in the middle of the room when you turn it on, goes about 2 feet, then turns and wiggles back to where it started 2' away. Wheels are cleared of hair, etc, blew it out with compressed air for dust on sensors, etc. It still responds to the bumber, turns 45 degrees or so then starts wiggling again. Any ideas?
Re: Roomba Discovery wiggles back and forth and turns...
No matter your model Roomba, this occurs when Roomba has gone "crazy." Its brain is no longer working properly and you can usually tell this when you've cleaned the dickens out of it a few times and the behavior is still the same. There's only one possible user fix and that is to take out the battery, hold down the power button for 20-30 seconds then reinsert the battery.
If that doesn't do the trick, IRobot might send you something called an Ozmo which you put in the data port to rewrite Roomba's brain. Unfortunately this requires it to be under warranty unless you get lucky. Good luck, all!
Re: Roomba Discovery wiggles back and forth and turns...
In the Roomba service manual it says that this is the result of a wheel drop switch problem - it may have failed (replace), worked loose (fix with hot-melt glue) or be dirty (clean with alcohol and blow dry). However I got the same symptoms on my Roomba Sage and the problem was that only one side of the brush guard had clicked back into place after I had cleaned the brush and roller. The other side projected down just enough to trigger the wheel drop switch. An easy fix, which makes a nice change!

TYhe iRobot Roomba has different model designations. Here is a webpage with a list of what the beeps mean in the 400 series. I am thinking that is what you have. 3 beeps means the dirt cup is dirty, filters are dirty, or debris in collecting and it needs to be cleaned.

Hope this helps. If it does, I would appreciate a vote. Thanks,
If your Roomba goes "uh-oh", beep-beep-beep, that's a 3-beep error code, indicating that your vacuum motor is stalled. Remove the grill from the outside (back) of the dustbin and make sure that the impeller (looks like a fan) turns easily and is not clogged with dirt. Then try to run the robot with the bin ON but the grill OFF. You should be able to tell whether the vacuum impeller is spinning. If not, you'll need a new bin. You can confirm wth customer support by calling 1-877-855-8593.
cor2an, That sounds like a classic battery failure in the Roomba discovery series. There are sensors inside the battery pack that go bad too. Either way...it's not very practical to repair the battery....the best shot you have would be to order a replacement battery. You just pop the old one out and then put the new one in.
They are available from iRobot for $69 at this link: http://store.irobot.com/product/index.jsp?productId=2799714&cp=2804606.3358509&ab=CMS_AccSuper_Roomba400_102308&parentPage=family
There are sources of less expensive (about $35) Genuine iRobot quality batteries also.

Mine used to buck and spin and then stop. Don't know if this will work, but it did for me. Before turning my Roomba on, I hold it on the floor and move it back and forth a few times so that the wheels spin. This seems to break up the initial resistance in the wheels and it solved my problem. Good luck.
I had the same kind of problem with my model 400 today...after starting it and having it go in a circle for 30 seconds or so it would finally run into something and then back up a few inches, turn, then go forward a few inches, then back up a few inches, turn, then go forward a few inches, etc., etc.. I tried cleaning off the four pairs of sensors under the bumper and blowing out various things underneath (by mouth since I didn't have any canned compressed air). It didn't really help. It then occurred to me that I had a leaf blower! I put the Roomba upside down on the grass, put the leaf blower on high, and blew at it from all directions and up close. More dust came out than I thought would. It has been running normally now for the last 45 minutes.
I had the same back-up, turn, move forward a couple inches, backup-up, etc. problem. Try cleaning/cutting the hair, etc. out from around the brushes, as well as around the ends of the brushes. Also, try a Q-tip to clean out the four pair of sensors (on my Roomba there are four pairs of little lenses under the bottom of the bumper) that (apparently) can cause the Roomba to think it is going over a cliff so it backs up. I didn't have a can of compressed air, so I turned it over on the grass and went after it with a leaf blower..up close. Lots of dust came out and it has worked fine since.
