How to Service a Dyson V8 or V7 Stick Vacuum: A Step-by-Step Guide

Why Service Your Dyson Stick Vacuum?

Customers typically bring their Dyson stick vacuums in for service when the machine starts “pulsing.” This issue is often caused by clogged filters, which reduce airflow and trigger the vacuum’s protective pulsing feature. The pulsing occurs because the air that flows through the vacuum cools the motor, and when airflow is restricted, the machine pulses to prevent the motor from overheating.

While many online resources suggest simply replacing the filter to solve the pulsing issue, this is only a partial solution. Over time, the cyclone inside the vacuum can also become coated with debris, further reducing airflow. Additionally, debris can accumulate inside the narrow areas of the vacuum head, leading to reduced performance. In this guide, we’ll cover a full-service approach to address these issues.

Step 1: Inspect and Disassemble the Vacuum

First, we need to inspect the vacuum and begin disassembly:

1. Remove the Canister: Start by emptying the canister and then detach it from the vacuum body using the clip located near the bottom. Once removed, check for any obstructions or debris inside the canister. If necessary, blow out any debris with compressed air.

2. Detach the Cyclone: Next, remove the cyclone from the motor housing by pressing the buttons on either side and sliding it up. The cyclone should now be separated from the motor housing.

3. Inspect the Cyclone: Take a look inside the cyclone for any buildup of debris. Often, you’ll find dust and other particles stuck inside, which can impede airflow. You can demonstrate this by tapping the cyclone gently to release some of the trapped dust.

4. Clean the Motor Housing: Inspect the motor housing for any fine dust that may have bypassed the cyclone. This dust can cause the motor to retain heat and run warmer, so it’s important to clean it out thoroughly.

Step 2: Clean the Components

With the major components disassembled, it’s time to clean them:

1. Blow Out the Cyclone and Motor Housing: Take both the cyclone and motor housing outside and use an air compressor to blow out any trapped debris. This step is crucial for maintaining proper airflow and preventing overheating.

2. Clean the Power Head: Regular maintenance of the power head is essential for optimal performance. Start by removing the brush roll using a large flathead screwdriver or a coin. Inspect the area around the brush roll for any buildup of hair or debris.

3. Remove Debris: Use a pick or a small brush to remove any debris from inside the power head. While this vacuum wasn’t too dirty, it’s common to find significant debris buildup, especially in machines that haven’t been serviced regularly.

4. Clean the Brush Roll: Once the brush roll is removed, clean it thoroughly. If there’s any hair wrapped around it, use a pair of scissors or a razor blade to cut it away. You can also use isopropyl alcohol to clean any remaining grease or dirt.

5. Lubricate the Brush Roll Bearing: If necessary, apply a small amount of grease around the brush roll bearing to prevent future lock-ups, especially if you have pets.

6. Clean the Exterior: Use denatured alcohol to remove any paint scuffs or marks on the vacuum’s exterior. Be aware that denatured alcohol can leave a white residue, so follow up with an all-purpose cleaner to remove any leftover film.

Step 3: Reassemble and Final Check

After cleaning all the components, it’s time to reassemble the vacuum:

1. Reattach the Cyclone and Canister: Snap the cyclone and canister back into place on the vacuum body.

2. Reinstall the Brush Roll: Put the brush roll back into the power head and ensure it spins freely.

3. Final Inspection: Give the vacuum one last inspection to ensure everything is in working order. If you have an air compressor, use it to blow out any remaining dust from the vacuum’s interior.

4. Test the Vacuum: Turn the vacuum on and check for any issues. If it’s still pulsing, consider replacing the filter, as it may be the cause of the problem.
