If your Dyson Laser Slim Fluffy or Detect Slim floorboard head has become loose at the neck, is leaking air, or feels wobbly when you vacuum, the rubber tube neck joint is probably worn or damaged. The good news: you don’t need a whole new vacuum – you can replace just the rubber neck section.

In this guide, we’ll walk through how to safely disassemble the head, replace the rubber tube with a high-quality replacement part from VacRevive, and reassemble everything without damaging the cleaner head.

Which Dyson Models Does This Apply To?

This repair method applies to the slim fluffy heads used on:

• Dyson V12 Detect Slim
• Dyson V15 Detect
• Dyson Gen5 Detect
• Other compatible Laser Slim Fluffy / Detect Slim floor heads

The part we’re working on is the rubber tube neck joint where the metal tube/rod meets the head. Over time this joint can crack, harden, or lose its seal, causing:

• Loss of suction at the head
• Air leaks and whistling sounds
• Loose or wobbly neck connection
• Stress on the cleaner head and wand

Instead of replacing the whole head, you can swap this rubber tube section using our dedicated replacement part:

Tools and Parts You’ll Need

• Replacement rubber neck tube / head tube: Dyson V12 / V15 / Gen5 Laser Head Tube Replacement Part
• Small Phillips or precision screwdriver
• A flat plastic pry tool or spudger (to avoid marking the plastic)
• Clean cloth or towel to work on

Step 1 – Remove the Laser Slim Fluffy / Detect Slim Head

Start by detaching the cleaner head from the wand. Make sure the vacuum is switched off and ideally remove the battery from the main unit for safety.

1. Press the quick-release button and pull the head away from the wand.
2. Place the head upside down on a soft surface (like a towel) so it doesn’t get scratched.
3. Inspect the neck area – you’ll see the plastic collar, metal tube, and rubber section in between.

Step 2 – Open the Head Safely

In the video tutorial, we show exactly which screws to remove to open the neck assembly without cracking the casing.

• Use a small screwdriver to remove the visible screws around the neck area.
• Keep all screws in a small tray so you don’t lose them.
• Avoid forcing any plastic tabs – if something won’t move, check for a hidden screw first.

Once the screws are out, gently pry apart the plastic covers around the neck. Work slowly around the edges to avoid snapping clips.

Step 3 – Remove the Old Rubber Tube Neck Joint

With the plastic cover removed, you’ll now see the metal tube and the old rubber neck joint.

1. Carefully slide or peel the old rubber tube away from the metal and plastic ends.
2. Check for cracks, splits, or hardened rubber – this is usually the cause of air leaks.
3. Clean any dust or debris from the mating surfaces so the new rubber can seat properly.

If the surrounding plastic or head body is cracked rather than just the rubber, consider replacing the entire cleaner head instead:

Step 4 – Install the New High-Quality Rubber Replacement

Now it’s time to fit the new rubber neck tube from VacRevive.

1. Align the new rubber tube with the metal rod and plastic base so it sits in the same orientation as the original.
2. Slide the rubber over both ends, ensuring it seats firmly and evenly.
3. Check that there are no twists or gaps – a proper seal is critical for airflow and strength.

The replacement part is designed to match the original fitment on Dyson V12 / V15 / Gen5 laser heads:

Step 5 – Reassemble the Neck and Head

Once the new rubber tube is fitted, reassemble the plastic covers and screws in the reverse order.

1. Carefully clip the plastic housing back around the neck, making sure no wires or edges are pinched.
2. Reinstall all the screws, tightening them evenly (do not overtighten into plastic).
3. Check that the neck now feels firm, rotates smoothly, and has no excessive play.

Finally, click the head back onto the wand and give it a quick test on the floor. You should notice:

• No wobbling at the neck
• Improved suction at the head
• No air hissing from the joint

Other Maintenance Tips While You’re Here

While your Laser Slim Fluffy / Detect Slim head is off the machine, it’s a great time to check a few other components:

• Make sure the brush bar is free from hair and threads.
• Inspect the wands and seals for cracks or air leaks.
• Check your battery and filters if the runtime feels short or power is inconsistent.

When to Repair and When to Replace

Replacing the rubber neck joint is a cost-effective fix if the rest of your cleaner head is in good condition. However, if the housing is cracked, the neck is broken, or the head has suffered heavy impact, it may be better to replace the entire head or consider a refurbished set.
