When I turn my Roomba on, it doesn't go forward anymore.

Joey111 you did not tell us how many times your Roomba beeped. It does sound like a stuck bumper. You can try this first

1. Move Roomba away from any obstructions.

2. Press the bumper to feel for inconsistencies.

3. Clean the bumper from underneath using canned air or q-tips.

Here's a video on how to do the repair:

My Roomba had the 9 beep code. I read these answers. I removed the bottom cover to take a look. Everything was covered in dust. Cleaned it very well. Replaced the cover. The Roomba ran normally. Don't know if it will continue working, but it is less work than getting out a soldering iron. Try this first.

my Roomba started circling today so I cleaned 4 eyes ( sensors on the bottom ) with alcohol. problem solved.

You can try iFixRobot who repairs the bumper sensors and the circle dance problem.

This is know as the "circle of death 9 beep error" or "circle death spiral" The cliff/bumper sensors have failed and need to be replaced. Otherwise, it will never work again. It will only go it circles. If you have a soldering iron and are not afraid of repairs, you can get the sensors for under $10 and replace the sensors.

Here is a youtube video to diagnoise and repair: https://www.youtube.com/watch?v=7lYBLLCY...

Here is a repair place that also sells repair kits: http://www.eesolutions.ca/

The sensors themselves are available on eBay and possibly other places. Just google "Roomba circle of death repair"

I did not repair mine. I gave it away to someone who is good at repairs and it is working very well.

Agree with the cleaning trial. I disassembled it and blew it out with compressed air. Also cleaned the sensor windows thoroughly, and it was in working order again.

my scooba 450 will not move. the clean light just keep on spinning but the unit will not move.

thank you
