Question about iRobot Roomba 4210 Bagless Robotic Vacuum

2 Answers

Roomba 415 bumps into something 3 time, stops

After it stops it peeps eh oh 2 times. If I'm quick enough and move the roomba it continues until it hits the next wall and stops again I cleaned it, blow all the dust out with blow-dryer and hit the front couple of times also. Nothing seems to work. Now it just goes back and forth in a "seeking way" 3 times and turns around and does it again. Hope you can help me, this is my 3rd roomba, I love them (when they work but all 3 have not survived more then a year). Txs

Same problem. Cleaning the cliff detector with Q-tips and wipe it clean (after all, what's the point of vacuum cleaner if it cannot handle dust???), even tape the cliff detector with while paper to see if it helps, hit the front and side 20 times, still nothing works. It either goes backward, or spins until it runs out of battery, or just can't go. - nothing works. I got a second Roomba and just hope that it last more than a year!

Good morning...My brand new Roomba 440 after being charged all night will run on its own for a while...but it bumps into walls or chairs and changes direction as it should, but then it stops in the middle...


Rather than try to repair it or look into it, call the dealer or take it back to him as you will invalidate your warranty if you do anything to the unit, and that is not worth it. Let the dealer worry about it.

I starts and tehn stops and beeps three times. I can start it aain and it will run but then it does the same thing'


Hi,

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.

Here is the webpage: http://uksupport.irobot.com/app/answers/detail/a_id/1047/kw/iRobot%20Roomba%20Discovery%20SE%20Bagless%20Robotic%204200%20series%20Vacuum%20beeps%203%20times/related/1

Hope this helps. If it does, I would appreciate a vote. Thanks,

My roomba spins and moves back and after 2-3 minutes stops and makes the uh oh sound followed by 10-12 beeps I cant say Im sure how many. Some days before stopped cleaning and told me to remove and clean...


Your bump sensors are malfunctioning. I had the same problem.. The best thing to do is order a repair kit. I ordered mine from EESolutions.ca and it worked great. I'd recommend it.

Yes, this is known issue and if your bumper moves freely, you might be facing a sensor fault caused by poor quality of components.
Here is a guide to fix it

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.

Roomba Says
What It Means
What You Should Do

Play sound The battery is low and needs recharging
• Connect the robot to the charger or Home Base® and recharge the battery. “Ehh”

• Pick up your robot and turn it over.*
• Check for any debris that might be caught underneath the front bumper, around the Cliff Sensors.
• Wipe the Sensors with a lint-free cloth or use compressed air to clean them out.

• Lift the robot and place it down again.
• Press the Clean button to restart the cycle. “Uh-oh” plus 1 beep

The robot's main brushes are stalled
• Pick up your robot, turn it over* and remove the wire guard.
• Look for something blocking the brushes; you may need to remove and reinstall the brushes to remove the obstruction. “Uh-oh” plus 2 beeps
The robot's Side Brush is stalled
• Pick up your robot and turn it over*
• Check to see if something is wrapped around the Side Brush.
• Remove the Side Brush with a screw driver and check for string or hair wrapped under it.
• Replace the Side Brush, place Roomba in the center of the room and press Clean to resume cleaning. “Uh-oh” plus 3 beeps

The robot's vacuum is stalled

Play sound
The robot's Drive Wheels are stalled
• Your robot may be stuck, or something may be caught in a wheel.
• If it's stuck, place it in the center of the room and press Clean. It should resume cleaning.
• If it is not stuck, lift the robot, turn it over* and look for something caught in the wheels. Test the wheels by pushing them in and out and making sure they rotate freely. Place robot in the center of the room, press Clean, and it should resume cleaning.
If this continues to happen every time you clean, you may need a software upgrade. Contact iRobot Customer Support.
“Uh-oh” plus 5 beeps
The robot's Cliff Sensors are obstructed

• This failure requires you to contact iRobot Customer Support. Click here to send us an email. “Uh-oh” plus 10 beeps

The robot's bumper is not registering obstacles
• If the robot travels for a long distance without bumping into anything (which would be unusual), it might think it’s stuck and can’t move; press Clean again and it should resume cleaning.

It could be the power button itself. If you have a Roomba remote, try using that to power on the robot.

IRobot Roomba Discovery not moving across room.


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.
