The short version
- 01Take the bin right out and put it back until it clicks positively into place.
- 02Check the filter is actually installed, since the robot will not run without it.
- 03Reseat the filter the correct way round and push it fully home.
- 04Wipe the metal contacts on the bin and the matching contacts inside the robot.
- 05Dry the bin and filter completely if either has been washed recently.
- 06Contact iRobot if the bin seats correctly with a dry filter and the error persists.
Raw message
Error one four (1-4). Re-install Roomba’s bin, then press CLEAN to restart. Reinstall the bin, then press Clean
Likely causes
- A bin that is not fully seated, so the robot does not register it.
- A missing filter, which the i Series chart calls out specifically.
- A filter fitted the wrong way round or not pushed fully home.
- Dirty or damaged bin contacts on the bin or in the robot.
- A failed bin detect switch, which iRobot names as a thing to check.
- Moisture in the bin after a wash that has not fully dried.
What the robot is checking for
On the 600 series the message is “Error one four (1-4). Re-install Roomba's bin, then press CLEAN to restart,” and the cause is that Roomba is not detecting an installed bin. The i Series message is “Reinstall the bin, then press Clean,” and its cause entry is more informative: bin not present in robot, ensure filter is installed in bin, check bin detect switch.
Those three clauses are effectively a checklist, and only the first is obvious. The bin can be physically present and correctly seated and the robot will still report this error if the filter is missing — the filter is part of what the robot is checking for, not an accessory.
The third clause matters too. There is a physical bin detect switch, which means this error can be a mechanical fault rather than a mistake you have made, and it is worth knowing that before taking the bin in and out twenty times.
Reseating the bin and the filter
Take the bin fully out rather than pressing on it in place, then slide it back until it clicks positively home. A bin that is nearly seated looks identical to one that is seated, and the click is the only reliable confirmation.
Then check the filter, because this is where the error most often hides. Confirm one is fitted at all, that it is the right way round, and that it is pushed fully into its slot rather than sitting slightly proud. A filter that is not fully home holds the bin a millimetre out of position and defeats the detection.
If either has been washed, make sure both are completely dry. iRobot's filters are not intended to be washed, and a damp bin or filter causes problems beyond this error — so if in doubt, leave it out to dry for a day before fitting it.
Contacts, and the switch
The 600 series chart directs you to the bin and bin contacts for this error. Those are the small metal contacts on the bin and their counterparts inside the robot, and they get dusty in a device whose whole job is collecting dust. Wiping both sets with a dry cloth is a thirty-second check that occasionally resolves the whole thing.
If the bin clicks in, the filter is present and dry, and the contacts are clean, the remaining candidate is the bin detect switch that iRobot names. That is a hardware fault rather than a maintenance issue and it is not something to fix at the kitchen table.
At that point, contact iRobot Customer Care. Their published advice for faster service is to have the robot charged and with you, its serial number ready, and proof of purchase from an authorised retailer if you are claiming under warranty.
