Dirt dog failed test 10 and all higher tests

[newmom]

After I got so much help from this list on repairing my 400, I got up the courage to see if I could fix my old Dirt Dog. The Dirt Dog is still covered by Hammacher Schlemmer but I hate to return it because I liked it so well before it died. Anyway, when I got through diagnostics past the test 9, I was feeling pretty good. But then at test ten, it made a sickly toned noise and none of the tests past that seem to do much of anything at all.

When I try to use it , it moves a little as if it is in molasses, and attempts to circle and wall follow but just can't seem to do it. The front wheel does move freely and the wheel holder is clean. Manual rotation shows no change from the solid red light.

I imagine my advise will be to send it back, but having just learned how to use the diagnostic tests, I really wanted to try to see if it could be repaired first.

What do ya think?

[Fraggboy]

I'm sure you could repair it, once Ed, or someone else points you in the right direction. They can also give you a better idea if you should repair it, or exchange it.

[newmom]

A quick update, I am still learning. I just realized the DD doesn't have an impeller so that threw me off a bit on my tests. I guess it didn't fail that test. For some strange reason, my DD seems to be running a little better, but it still shows a solid red light during test 10 when I turn the front wheel with my hand. (not sure I am doing it right) Passes the brush test and during the spinning brush test, brush turns but slowly. When running the DD, the spinning brush turns at various speeds, from not turning at all, to a solid slower than normal turn. It will run for a few minutes (maybe longer but I don't push it) It has some normal pattern movement and some unusual pattern.

[mfortuna]

Is test 10 the front tach test? You may need to clean the wheel (it should have alternate white and black halves, it the white is too dirty it may cause an issue). You could try popping the wheel out and blowing some air up towards the sensor.

The brush could be slippage in the gearbox or between the brushes and gears. It could also be the motor is failing.

The parts from your other 400 could be used to fix the Dirt Dog BTW.

Lost me at SCI tests, This is all way over my head, but I am sure lots of other members understand what this means. I decided to return the Dirt Dog when I saw another one on Ebay that was almost new and cost the same as what I will get back from H and S. I guess it just made more sense. I still feel I learned a lot and if that DD hadn't been under warranty, I would have continuted with working on the front wheel problem. Thanks again for all the help, and I am going to keep the info Vic posted about the DD, because I don't give up easily and the time will come when it will be more meaningful to me.

I did just notice the remarks in slightly bolder print, which pertains to which tests don't apply to the DD, and now I am guessing that is the info you were thinking would be more helpful, and that is more helpful. You guys are GRREEEEEAAAATE

[vic7767]

Just save the SCI Dirt Dog text. It is just an ASCII story book of what the Built in Test program sees and reports either a PASS or FAIL of a particular test.

[mfortuna]

SCI is the serial command interface. There is a DIN connector just above the charging jack but is commonly refered to as the SCI jack. If you attach the proper cable between this connector and a PC you can display the test information. You can also do cool things like control the robot. In the case of running diags it has nothing to do with SCI but is just used to display test information. When the robot sits on the dock or has the charger plugged in, this port will display charging information.

[newmom]

So Cool. Where does one get a proper cable? Thanks for taking the time to explain this to those of us who don't have the background many of you have.

[vic7767]

You can go directly to the iRobot web page then select "robots for the home" then select "accessories" then select "Create" then choose either the USB cable or if you have an older computer you can choose the DB9 pin connector cable. Here's a direct URL to the USB cable: http://store.irobot.com/product/index.j ... age=family

[mfortuna]

If you want to go wireless you can do that do, for even more of a "geek" factor. If you decide you would like to try that let us know.

Can you tell me if this item available on Ebay is the same thing I need?

http://www.ebay.com/itm/Roomba-OSMO-Ser ... 2eb0704438

[vic7767]

No, that cable is for connecting a Scheduler remote to the Roomba to flash the firmware with the scheduler feature. It has no circuitry to allow communication between a terminal program on a PC and the serial interface in the Roomba.

[newmom]

Thanks for clarification.

[JEDi]

How can I setup my Dirt Dog for wireless?

[vic7767]

Your Dirt Dog has a built in interface (7-pin mini din) that is located just above the charger jack and is covered by a removable plastic cap. There is a device made for the Roomba called a Rootooth that provided a RF wireless interface. Using a PC or an Android app that has a bluetooth capability you can connect to the Roomba and send commands to it. Here is a URL to Amazon.com where you can read about and purchase the Rootooth.
