Top 20 iRobot 4150 Roomba Vacuum Questions & Answers

What seemed to be the problem?

You will need to clean out the debris found in the gear box. Example here: http://www.imayne.co.uk/device/irobot-mod/

You will need to remove the gears cover from the cleaning head module and remove all debris found inside.

Seems like a bad battery. The Roomba detects that there is a battery present so the battery must be at fault.

Try removing brushes, cleaning thoroughly removing yellow tips if there is any and removing hairs, re install brushes and turn manually about 20 turns and re try

It should take about 6 hrs to charge. I had the same problem and reset the charging circuit. 1) Charge it until the green light comes on. 2) Unplug and pull battery out. 3) hold down the power on button 15-30 seconds. 4.) Put the battery back in, plug in the charger (direct - not through the dock) and charge for 72 hrs. Then, run at Max clean until the "I'm dead" tune plays.

Hi, try setting the Roomba on the floor, powering it up, pressing down hard on the front, just above the front wheel, and hitting "clean" or "spot." My Roomba had the same problem, and this seems to do the trick for it. I think it has something to do with the Roomba thinking the front wheel is extended (which would indicate a cliff) even though it's really not.

If this doesn't work, you might try pressing down over whichever wheel doesn't turn when you turn the Roomba on.

Take care

EHH sound:------- Cliff sensors are dirty or need repair.Try cleaning the sensors and check.If still the same problem then the sensors needs to be rechecked and its connections has to be replaced. You can try this options:-- 1) Pick up your robot and turn it over*. 2) Check for any debris that might be caught underneath the front bumper, around the cliff sensors. 3) Wipe the sensors with a lint-free cloth or use compressed air to clean them out. --------- Doesn't beep at all:-- A wheel is stuck or is not touching the ground:--- 1)Lift the robot and place it down again.

2)Press the Clean button to restart the cycle. ----------- Turn Roomba over and remove any debris on the under side when you hear the sound "Ehh." Check for debris in the Cliff Sensors. Inspect the front bumper and remove any debris caught between the bumper and the rest of the vacuum.
If still the "ehh" sound then the sensor needs to be replaced. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Yes, a common issue with the cleaning head module, chm. You will need to diassemble the Roomba and remove all debris from the CHM. Also take a look in its gear box.

I had the identical problem. I cleaned the brush but the problem persisted. I then put in a new brush that was provided in the box and the problem vanished. I have since used the cleaning tool on the old brush and will try and reinstall it to see if my cleaning worked. In any case a new brush will do the job.

Press each cycle button and see if it starts up. I don't know if this is new and you just got it, but if so, you may need to remove any straps and retainers blocking the brushes etc.

It may need a longer charging period to bring the battery up to full charge. If you have a voltmeter, measure the battery voltage while it is being charged--it should read several volts above the rated battery voltage. If nearly equal, the charge unit may need repair or replacement. Good luck!

If your Roomba's speaker isn't working, you need a new Roomba regardless. Give a call to customer support (877-855-8593) and they'll help you out.

If you have a 400 series Roomba, try removing the battery, then holding down the power button for ten seconds, then recharging the unit before you run it again.

If you have a 500 series Roomba, don't take out the battery-- just press and hold the "spot" and "dock" buttons for about fifteen seconds. The Roomba will play a tune, and you can then charge it and try running it again later.

may need to clean inside.the wheels pick up trash and deposit it on and near motors.also try to take ends of roller brushes off and clean hair ect.

you need to do a wheel motor check. to put your roomba in diagnostic mode follow the link below http://swiftracer.com/index.php?myPage=RoombaDiagnosticMode.php

If you have the 4XX series or 4XXX series then your issues are coming from the sensor in the wheels. You will need to clean them PROPERLY.
