Roborock Error 5 — Main brush jammed

Severity: Warning — The robot stops cleaning until the main brush turns freely again. S5S6S7S8
Last verified: 2026-10-05 Tools: a torch, and the brush cleaning tool if your model's manual uses one Time: ~10 min Difficulty: easy

DIRECT ANSWER

Error 5 means the robot's main brush cannot turn. Roborock lists three places to check: hair or thread on the roller, both ends of the brush, and the two slots inside the robot where the brush sits.

What to check, in order

1

Hair or thread wrapped around the roller

Long hair, pet fur and thread can wind into tight bands along the roller. Clear these first. A roller that looks clean afterwards can still be held at the points below.

2

Hair packed at the brush ends

Hair can work past the roller into the bearing area and hold the brush while the middle looks clean. How you reach the ends depends on the model, so use the model notes.

3

Debris in an installation slot

The brush ends sit in two slots inside the robot. A loose thread or small object there can stop a brush that is itself clean.

4

Brush or cover not refitted correctly

An end that isn't seated, a cap that isn't locked or cover clips that don't hold can keep the brush from turning properly. The manuals end brush maintenance by securing these parts, so check them before you look anywhere else.

5

Damaged brush or a fault you can't reach

Cut bristles, a cracked end or a bent roller may mean the brush needs replacing. If everything is clean, seated and undamaged and Error 5 still comes back, you can't pin down the cause at home. Roborock directs that case to support.

HOW TO FIX IT

SAFETY · READ THIS FIRST

Switch the robot off before you handle the brush. If your manual shows a cleaning tool for cutting hair, keep your fingers clear of its edge. Don't force a roller that won't turn by hand.

Switch off and confirm the alert

Power the robot off before handling it. Check that the App or voice prompt says Error 5 or main brush. If the alert names a maintenance brush, that is a different code with its own checks, covered in the branches below.

Remove the brush and clear the roller

Turn the robot over, release the cover clips and lift the brush out. Pull off wrapped hair and thread. Only use a cutting tool if your model's manual shows one for this job. On models with two brushes, clean both.

Clean both ends the way your manual shows

Roborock asks you to check both ends of the brush as well as the roller. Depending on the model, you twist the end cap to unlock it, pull it out, or only clean the bearing area. Don't force off a part that your manual doesn't show as removable.

Look inside both installation slots

With the brush out, shine a torch into the two slots where the brush ends sit. Remove any hair, thread or debris you can reach without pushing tools deeper into the robot.

Refit and inspect before testing

Lock the end caps if your model has them, set both ends into their slots and close the cover until the clips hold. Look for cut bristles, a cracked end or a bent roller. Cleaning won't fix that kind of damage, so plan on a replacement brush for your exact model.

Run a short test, then decide

Start a short clean. Roborock's Error 5 article suggests testing with Carpet mode on. Only do this if your App has an option with that exact name. If the same error comes back after you've cleaned the ends and slots and refitted the brush, contact Roborock support.

IF IT STILL FAILS

IF
Error 5 returns soon after you cleaned only the visible roller
→ Go back to the parts you skipped. Clean both ends using your model's method and check both installation slots before you test again. Source: Roborock Support: What should I do when error 5 occurs?
IF
The brush is clean, seated and turns by hand, but Error 5 persists
→ Contact Roborock support. Give them the model, the exact alert and a short video of a test run. Roborock's Error 5 steps don't include a factory reset, and a clean brush on its own doesn't tell you which internal part is responsible. Source: Roborock Support: What should I do when error 5 occurs?
IF
The alert names the maintenance brush on an S7 MaxV Ultra, S7 Max Ultra or S8 Pro Ultra
→ That is Error 42, which refers to a brush inside the dock. If the brush stopped on the left, check for something jamming it. If it stopped on the right, the dock filter may be blocked or fitted wrongly. Contact support if the error continues. Source: Roborock Support: Error 42, maintenance brush jammed (S7 MaxV Ultra, S7 Max Ultra, S8 Pro Ultra)
IF
Carpet Boost also switches on over hard floors
→ Roborock connects that symptom with something tangled in the brush. Clean the brush, check that it turns freely and retest. Taken alone, this symptom doesn't tell you anything about the motor. Source: Roborock Support: Carpet Boost activated on hard floors
IF
The brush is cut, cracked or bent after cleaning
→ Replace it with a brush made for your exact model. For an S7 MaxV, Roborock's US store lists a matching brush, shown in the parts card. That listing doesn't name the base S7, so check other models with Roborock first. Source: Roborock US store: S7 Main Brush listing (lists S7 MaxV)

WHEN TO STOP

STOP HERE

Stop and contact Roborock support in two cases: the brush still won't turn by hand after you've cleaned the roller, ends and slots, or Error 5 keeps coming back after a correct refit. Don't pry the brush out, push tools into the brush housing or open the robot to reach the drive. Have the exact model, the alert text and a short video ready.

FIELD NOTES

WHAT THE OFFICIAL DOCS LEAVE OUT — AND WHAT OWNERS REPORT

Roborock's Error 5 article is short. Its most useful part is the list of places to check: the brush, the two installation slots and both ends of the brush. If you only clean the roller, the ends and slots go unchecked, and they are the next things to look at when the alert comes back. A result after one clean and refit tells you where to look next, but it can't prove where the jam was. If the error stops after you work on the ends, keep the ends in your routine. If it stops only after you refit the cover properly, pay attention to seating next time.

The ends are where models differ. The original S5 manual describes cleaning the bearings and doesn't show removable caps. The S5 Max, S6 MaxV, S7 and S7 MaxV manuals use end caps that rotate to unlock. The S8 and S8 Pro Ultra have two brushes with caps that pull out. Use your own model's method rather than forcing a part that won't move.

A brush that isn't turning isn't always faulty. On the S8 Pro Ultra, Mop Only mode lifts the brush and stops it. A maintenance brush alert on the S7 MaxV Ultra, S7 Max Ultra or S8 Pro Ultra comes from the dock. It is Error 42 and has its own checks.

Error 5 appears in the error tables of the S6 MaxV, S7 and S7 MaxV manuals. For the S5, S5 Max, S8 and S8 Pro Ultra, this page relies on their brush maintenance sections. It has no model-specific steps for the base S6, Q5 or Q7, so on those robots follow the alert wording and your own manual. The Carpet mode retest only applies if your App has that option; other carpet settings may behave differently.

A clean brush that still triggers the error doesn't prove the motor has failed, and a factory reset isn't part of Roborock's Error 5 steps. If the error persists after a careful clean and refit, contact support.

FAQ · REAL QUESTIONS

What does Roborock error 5 mean?

The main brush under the robot can't turn. Roborock asks you to check for hair or thread on the roller, both ends of the brush and the two slots it sits in. Clean them, refit the brush and cover, then run a short test.

Why does my Roborock keep saying main brush jammed when the brush is clean?

A roller can look clean and still be held by hair at the ends, debris in an installation slot, or a brush or cover that didn't seat on refit. Check each with your model's manual. If all are clear and Error 5 persists, contact Roborock support.

How do I reset a Roborock after error 5?

Roborock's Error 5 guidance doesn't call for a factory reset. Clear the brush, ends and slots, refit everything and retest. If the same error returns, contact Roborock support rather than restoring factory settings.

Is error 42 the same as error 5 on a Roborock?

No. Error 5 refers to the main brush under the robot. Error 42 refers to the maintenance brush in the dock on the S7 MaxV Ultra, S7 Max Ultra and S8 Pro Ultra. If it stopped on the left, check for a jam; if it stopped on the right, check the dock filter.

How do I clear a jammed main brush on a Roborock S8?

Check the alert wording in the App first. The S8 has two main brushes. Its manual has you remove the bearings, pull out the brush caps, clean the ends and refit. Clean both brushes, then retest.
