Understanding and Fixing the iRobot Roomba 980 Suction Power Drop

Suction power is the heart of any robotic vacuum, turning a simple sweep into a deep clean. If you notice that your iRobot Roomba 980 is no longer picking up crumbs, dust, or pet hair as it used to, you’re likely experiencing a suction power drop. While the device is engineered for long‑lasting performance, a variety of factors can reduce its effectiveness. Below is a comprehensive guide that explains why suction can falter, how to diagnose the problem, and step‑by‑step instructions for restoring full power.


Why Suction Power Might Decline

There are several common causes that can reduce the Roomba’s vacuuming strength:

  • Clogged Filters – When the filters become saturated, airflow is restricted.
  • Full or Dirty Bin – A bin that’s nearly full or blocked by debris limits the vacuum’s intake.
  • Matted Bristles – Bristles wrapped in hair or fibers create resistance.
  • Faulty Brushroll or Motor – Wear or damage to the brushroll or motor can reduce suction.
  • Software or Firmware Glitch – An update may reset or alter suction settings.
  • Power Supply Issues – The device may be receiving less power than required.

Diagnosing the exact source requires a systematic approach. By following the steps below, you can identify the root of the problem and fix it efficiently.


Quick Checklist Before You Dive In

  • Verify that the Roomba is on the correct cleaning mode (Standard, Max, or Boost).
  • Ensure the device is fully charged; low battery can affect suction.
  • Confirm that the charging contacts are clean and free of debris.
  • Look for visible blockages on the brushes or in the suction channel.

If the checklist doesn’t reveal the issue, proceed to a more detailed investigation.


Step‑by‑Step Guide to Restoring Suction Power

1. Power Off and Inspect

First, turn off the Roomba and let it cool. This protects your hands from the motor and prevents accidental startup during the cleaning process.

  1. Remove the Bin – Slide the bin out of its housing. Inspect the inside for tangled debris or compacted crumbs.

  2. Empty the Bin – Use a flat tool or your hand (with gloves) to gently remove all waste. A full bin will significantly reduce suction.

  3. Check the Brushroll – Lift the brushroll and look for hair, string, or foreign objects wrapped around it. If you find anything, carefully cut or trim the excess.

  4. Clean the Brushroll Housing – Use a small brush or a damp cloth to wipe away any buildup that might restrict the brushroll’s movement.

2. Clean or Replace Filters

The Roomba 980 uses a combination of a primary filter and a foam filter. Over time, these filters collect dust and can become clogged.

  • Primary Filter – Located in the suction channel, this filter is usually a replaceable cartridge. Pull it gently out, rinse it under running water, let it dry completely, and reinsert it. If the cartridge shows visible wear or cannot be cleaned, replace it with a new one.
  • Foam Filter – The foam filter sits near the dustbin and is meant to catch finer particles. Remove it, press it lightly to release trapped dust, and replace it if it looks brittle or discolored.

3. Inspect the Suction Channel

A partially blocked suction channel can severely limit airflow.

  1. Remove the Dustbin Cover – Once the bin is empty, take off the cover.
  2. Look for Debris – Use a flashlight if needed. Pull out any small objects that might be lodged inside.
  3. Clean the Channel – Use a long, thin brush or a vacuum to remove any dust accumulation.

4. Examine the Brushroll and Motor

The brushroll is powered by the motor, and any mechanical issues can lead to decreased suction.

  • Brushroll Rotation – Spin the brushroll manually. If it feels stiff or doesn’t rotate freely, it might be jammed.
  • Motor Inspection – Look for unusual vibrations or noises when the Roomba is in operation. If the motor feels weak or is making grinding sounds, it may need servicing.

If you suspect motor failure, contact iRobot support or a qualified repair technician. Do not attempt to disassemble the motor yourself.

5. Reset the Robot

Sometimes software glitches cause a temporary loss of suction. Resetting the Roomba can clear these issues.

  1. Power Off – Ensure the device is completely shut down.
  2. Press and Hold the CLEAN Button – Hold the button for 10 seconds until the lights flash. This triggers a full reset.
  3. Restart – Power on the device and run a quick test on a small area to gauge suction.

6. Update Firmware

Keeping the Roomba’s firmware up to date ensures it runs optimally.

  • Connect the Roomba to the iRobot HOME app.
  • Navigate to the “Device” section.
  • Check for updates and install any available firmware.

Updates often include performance improvements, including suction optimization.

7. Test After Each Step

After completing each major step, test the Roomba’s suction on a test patch. Mark a small square (e.g., 1 × 1 meter) and observe how well the device picks up a layer of dry flour or dust. Record the difference between before and after each adjustment. This will help you confirm whether the issue has been resolved.


Advanced Tips for Long‑Term Suction Health

  • Schedule Regular Maintenance – Set a reminder every two weeks to clean the filters, brushroll, and bin. Consistent care prevents major blockages.
  • Use Appropriate Filters – If you have pets, consider using high‑filtration HEPA filters designed for pet hair. These capture more fine particles.
  • Keep the Vacuum Clean – Dust the exterior of the Roomba frequently. While the interior is usually sealed, a clean exterior helps maintain airflow.
  • Avoid Overloading the Bin – If the Roomba is used frequently, empty the bin after every few sessions to keep suction consistent.
  • Check Charging Contacts – Dirty contacts can affect power delivery. Wipe them gently with a dry cloth.

Common Questions Answered

Question Quick Answer
Why is my Roomba no longer picking up pet hair? Hair tends to wrap around the brushroll, blocking airflow. Remove the hair regularly.
Can I use any filter? It’s best to use filters specified by iRobot. Using a different brand may affect suction or damage the device.
What if my suction still feels weak after cleaning? The motor may be failing. Contact iRobot support for repair options.
Does charging the Roomba more often help suction? A fully charged battery provides stable power, which can improve suction performance.
How often should I replace the foam filter? Replace it every six months, or sooner if it becomes visibly dirty.

When Professional Help Is Needed

If after following all these steps your Roomba 980 still exhibits a suction power drop, it may be time to seek professional assistance:

  • Motor Replacement – A faulty motor can’t be repaired with simple cleaning.
  • Suction Channel Repair – Severe blockages or damage to the channel may require technical expertise.

If you’ve already cleaned the filter and brush, the next suspect is the internal belt that drives the side brush. Over‑time it elongates and slips, causing pressure loss. Replace it with the OEM part number 980‑B‑03; cheap clones often stretch faster.

yeah right, like anyone can afford OEM belts. Most of us just live with the weaker performance.
SO

Wheel issues affect navigation, not suction. Give the treads a quick wipe, they get greasy.
JA

The suction drop is always the battery – just charge it longer and it’ll be fine.
RA
Rashan 3 months ago
nah, battery only reduces runtime, not suction pressure. The motor still spins at full speed until the voltage really sags.
LI
Livia 3 months ago
i think you got it wrong, i read somewhere that a weak battery can cause the fan to spin slower.
MI

The motor’s torque curve is sensitive to the filter’s pressure drop. If you replace the foam with a higher‑efficiency one, you actually reduce suction because the fan works harder. Stick to the OEM part or a known compatible aftermarket.

Honestly, if you keep buying replacement parts you’ll spend more than a new robot in a year. Just upgrade to a Roomba i7.
SO
Sofia 3 months ago
Upgrading is an option, but most people just want to fix what they have. The i7 also has a filter that needs replacement, so you’re not escaping the maintenance entirely.
