Roomba Error 30 — Vacuum motor problem

Severity: Warning — robot pauses the job; bin and filter need care ijs
Last verified: 2026-07-05 Tools: none Time: ~10 min Difficulty: easy

DIRECT ANSWER

Error 30 is the i, j and s series cousin of Error 8: vacuum motor struggling or filter clogged. Same drill — full bin and filter care. Still firing afterwards? Go straight to the motor check.

COMMON CAUSES · RANKED

1

Dirt-packed bin and filter MOST COMMON

Fine debris builds up until the motor can't move air through the system.

2

Moisture in the bin UNCOMMON

Running the robot with a still-damp bin after washing strains the vacuum motor.

3

Vacuum motor wearing out RARE

An error 30 that shrugs off clean parts means the motor itself is failing.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Empty the bin

Press the bin release on the back of the robot and empty it completely.

Clean or replace the filter

Remove the filter and tap it against a trash can. Filters never touch water; replace one past two months.

Rinse and dry the bin

With the filter out, rinse the bin by hand with warm water. It must be bone dry before reinstalling.

Contact support if it persists

A clean system that still throws error 30 points at the vacuum motor.
