Robot Vacuum Error Codes: Match the Model and the Message

Start with the model, not the number

As a precaution, write down the exact model, the number, the spoken or app message and what the robot was doing when it stopped. Look that combination up in the manual or support page for the same model. A code table from another brand or product line can point to the wrong part, so do not apply it to your robot.

The robot troubleshooting hub routes symptoms to dedicated pages. Use the relevant guide for wheel errors, brush faults, sensor errors, dustbin errors, charging errors, stops during cleaning or docking failures. As a precaution, check which models each guide covers and use the linked manufacturer page for the exact code.

The same number can mean different faults

The sources cited in this guide show that a number carries a different meaning from one brand or model to the next.

• Error 1 means a blocked LiDAR turret or laser on the Roborock Q5+ and Roborock S7. On the eufy Clean X9 Pro, it means a stuck front bumper. For the Roomba 500 to 900, e, i, j and s series covered by iRobot’s charging chart, Charging Error 1 means the robot does not detect a battery.
• Error 2 is a stuck bumper on the Q5+ and S7 and a stuck wheel on the X9 Pro. For all Roomba and Braava models covered by iRobot’s Charging Error 2 article, Charging Error 2 identifies a battery that is not charging.
• Error 26 is a dirty wall sensor on the Q5+, but a low-battery alert indicating that scheduled cleaning failed on the X9 Pro.
• The wall sensor fault is Error 26 on the Q5+ and Error 15 on the S7. The fault is the same, but the number differs between two Roborock models.

As a precaution, only the table for your exact model decides which meaning applies to the robot in front of you.

What changes by model

The table compares selected codes and a Samsung LED alert, with the model or series and a link to the source.

Roborock Q5+ and S7

The Q5+ manual identifies Error 5 as a main-brush jam and Error 6 as a side-brush jam; see the brush guide. Error 9 reports a missing dustbin and instructs installing the dustbin and filter; see the dustbin guide. Error 13 identifies a charging error, while Error 23 identifies a failed return to the dock. The charging guide and docking guide cover those separate symptoms; use the Q5+ manual for its code-specific instruction.

The S7 manual gives the same meaning to Errors 1, 2, 5, 6, 9, 13 and 23 as the Q5+. Its wall sensor fault is Error 15 where the Q5+ uses Error 26. As a precaution, compare any Roborock number against the manual for the exact model rather than assume a match across the range.

iRobot Roomba and Braava

iRobot’s charging chart names the 500 to 900, e, i, j, s, 100/1000, 200/2000, Plus 400, Plus 500, Max 700 and m families. Its entries include Charging Error 1 and Charging Error 101; both concern battery detection. The 101–121 group contains selected entries whose messages refer to the Roomba Home App. As a precaution, keep the full reported number and match its entry to your model rather than treating these ranges as interchangeable. The charging guide covers the documented actions.

The Charging Error 2 article, titled for all Roomba and Braava models, says that a fault has been detected and the battery is not charging. It asks the owner to check the robot and dock for liquid damage and to confirm that an authentic iRobot lithium-ion battery is in use, because aftermarket batteries can cause unexplained charging errors. If the error keeps recurring with an iRobot battery, the article directs owners to iRobot Customer Care.

The Roomba i Series Error 36 article identifies bin-full sensors that were not cleared after emptying into the Clean Base. For this i Series code, use that article’s sensor, bin and evacuation-path checks. The dustbin guide routes other bin alerts by model; the sensor guide covers other sensor faults.

eufy Clean X9 Pro and RoboVac L70 Hybrid

The X9 Pro alerts page identifies Error 1 as a stuck front bumper and Error 2 as a stuck wheel; the wheel guide covers its wheel checks. On this model, Error 13 reports a tilted robot, Error 14 asks for the dustbin and filter to be reinstalled, Error 21 reports a failed return, and Error 23 reports an inability to find the starting point. Error 26 indicates that scheduled cleaning failed because the battery was low.

For persistent X9 Pro errors, the manufacturer’s recovery note describes basic restart or network-reset options before forced recovery. As a precaution, use that complete note before operating the Reset button. The page also links to eufy support for assistance.

The L70 Hybrid page covers Error 14 on the RoboVac L70 Hybrid. That error means the dust collector is not inserted. The page asks the owner to power off the robot, check that the filter is installed in the dust collector, insert the dust collector until a click is heard, then power on and run a cycle to confirm it completes without issues. The number matches the X9 Pro’s dustbin alert, but the wording and the step are specific to the L70 Hybrid.

Samsung Jet Bot Combo

The UK Jet Bot Combo troubleshooting page groups guidance by symptom and includes LED color. For a Jet Bot Combo that is not working or has stopped during cleaning with a red status LED, it directs the owner to place the vacuum on the Clean Station to charge. Use the stops-during-cleaning guide for its covered models and the Samsung page for Jet Bot Combo instructions.

Safety before you test again

As a precaution, stop the robot if it is hot, damaged or has been exposed to liquid, and follow the manufacturer’s safety guidance before any further test. As a precaution, use a reset, firmware update or battery replacement only when the documentation for your exact model and fault calls for it.

As a precaution, if a code returns after a maintenance step, contact the manufacturer’s support with the model, the code and the steps you already tried.

Frequently asked questions

Is Error 1 the same on every brand?

No. Error 1 identifies a blocked LiDAR turret or laser on the Roborock Q5+ and S7 and a stuck front bumper on the eufy Clean X9 Pro. For the Roomba 500 to 900, e, i, j and s series covered by iRobot’s chart, Charging Error 1 identifies a battery-detection problem.

Are dust-container alerts the same across eufy models?

No. Both the X9 Pro and the L70 Hybrid use Error 14 for the dust container. The X9 Pro asks for the dustbin and filter to be reinstalled, while the L70 Hybrid says the dust collector is not inserted and asks for it to be pushed in until it clicks.

Should I reset the robot before contacting support?

As a precaution, use the recovery instructions for your exact model and fault before choosing a reset. The eufy X9 Pro page describes conditional recovery options and links to support for assistance.
