You're not supposed to be able to replace your own cliff sensors. They're recessed into the bumper. If you're out of warranty and determined to replace them, there are forums online where that information is laid out in detail. You can probably Google them.

My roomba no longer works on my area rug, it starts backing up continuously once it encounters the rug.


Sorry to read about your problem, I hope this helps you out.

iRobot Roomba Vacuuming Robots and the iRobot Dirt Dog Workshop Robot are equipped with four infrared Cliff Sensors that prevent robots from falling off stairs or ledges. The Cliff Sensors are located along the inside of the bumper. If the Sensors become obstructed by dust or debris, the infrared signal is weakened. Regularly inspect and clean the Sensors. Use compressed air for best cleaning results.

I robot rumba- does not go forward, keeps backing up and turning


sounds like one of the cliff sensors has gone bad. I think your options are to send it in for repair or buy a replacement sensor and swap it in.

Roomba 560: it only spins in one place, then stops & doesn't dock either.


If there's no message its probably a sensor malfunctioning. It might be a cliff sensor, the bump switch, or wheel-drop (left, right, or caster). Try cleaning the sensors and vacuuming things out as a first step.

Runs but doesn't vacuum/****. Sidebrush works fine. Cleaned the roller brushes, and that seemed to confuse the robot and now it keeps going backward a few inches, turning, and then starts going backward...


sounds like a sensor problem. pull and clean the front black/white caster assembly and the revealed movement sensor and the 4 cliff sensors along the bottom of the front. Make sure the front caster wheel turns freely. You may have to remove the roller from the caster assemply and push the axle out and clean it.

ERROR MESSAGE


The "cliff sensors" are what help Roomba make sure that it doesn't tumble down stairs or over a cliff. You can see picture of their locations here:

You can try just blowing a bit of compressed air on the lenses of those sensor since they can malfunction if dust builds up on them. If the sensors have gone bad, you can find new ones at places like
www.roboticvacparts.com or at this link

ERROR MESSAGE


When Roomba says "Please Inspect and Clean Roomba's Cliff Sensors" it means that Roomba 500 series sees a constant cliff.This can happen if Roomba was started on an uneven surface or got stuckon an obstacle during the cleaning cycle. Extremely dark-colored floorsurfaces may also contribute to this error. If this error occurs on aneven, light-colored floor surface, Roomba’s Cliff Sensors could be dirty or obstructed.To troubleshoot this issue, please follow these steps:
  1. Check the Cliff Sensors for obstructions.
  2. Clean the Cliff Sensor windows using clean, dry cloth.
  3. Move Roomba and restart in a new location.

The location of the (4) optical sensors can be seen here:

Occasionally these sensors do go bad and that can be a hassle since iRobot doesn't like to sell replacements...they prefer you send the whole robot back to them. If you are handy and willing to replace yourself, you can purchase replacements from some reputable vendors like www.RoboticVacParts.com

Can not charge thr battery


bbaker58,
When you press the "clean" button after charging, does the Roomba give you any audible tones? Those tones are the key to understanding failures in the 400 series. See chart below to decode those tones
If you get no tones at all, then either (1) you're not getting power from the battery to the main circuit board or (2) the main circuit board is dead. You really have to open the unit up to figure out which it is. Circuit board replacement is a pretty involved procedure since it requires disassembly of almost the entire robot. If you are brave and want to try it, replacement PCAs are available from places like www.RoboticVacParts.com. They are my favorite shop because they sell parts tha iRobot refuses to sell to consumers and they're prices always beat what iRobot charges.
