Introduction

This guide will help you replace the lower hose on a Shark NV 752 vacuum cleaner. The steps outlined are also applicable to other Shark models like the NV 750 and similar designs.

 

Step 1: Prepare for Disassembly

  1. Identify the Hose: Locate the cracked or damaged lower hose on the vacuum’s power head.
  2. Gather Tools: You will need a Phillips head screwdriver and a T20 security bit to remove the screws.

Step 2: Remove the Base Plate

  1. Unscrew the Base Plate:

    • Front Screws: There are two shorter screws with regular-sized heads and one short screw with a smaller head in the center.
    • Center Screws: Remove the screw holding down the clear cover in the middle. This screw has a small head as well.
    • Security Bit: Use the T20 security bit to remove the special screw in the center.
  2. Total Screws: Ensure all 11 fasteners are removed. This includes:

    • 2 short screws on either side of the brush roller with regular heads.
    • 2 small screws with smaller heads in the front.
    • 1 T20 security screw in the center.

Step 3: Access and Remove the Damaged Hose

  1. Expose the Hose: Carefully lift the base plate off, exposing the hose and internal components.

    • Wires: Be cautious with the wires; avoid moving them more than necessary to prevent rerouting issues later.
  2. Cut the Wire Inside the Hose:

    • Use wire cutters to cut the wire inside the damaged hose.
    • Remove the Hose: The hose may come out easily or require some effort. If the plastic part of the hose remains stuck, use needle-nose pliers to extract it.

Step 4: Prepare the New Hose

  1. Clean the Hose Connection Points:

    • Spray isopropyl alcohol on the connection points to clean them.
    • Focus on cleaning the ends of the hose that will be glued, but it doesn’t have to be perfect.
  2. Select the Right Adhesive:

    • Avoid Super Glue: Use an adhesive that maintains flexibility. Super glue and similar products that dry rigid are not suitable.
    • Apply Adhesive: Apply the adhesive to the ends of the new hose.

Step 5: Install the New Hose

  1. Insert the New Hose:

    • Screw one end of the new hose into the connection point.
    • Apply adhesive to the other end and screw it into place.
  2. Reposition the Hose and Wires:

    • Ensure the hose sits correctly inside the power head.
    • Align the peg at the bottom and position the exhaust port correctly.
    • Reroute the wires through their original channels.

Step 6: Reassemble the Power Head

  1. Snap the Top On:

    • After the hose and wires are in place, snap the top cover back onto the power head.
  2. Replace the Screws:

    • Reinsert the screws in their original positions:
      • 2 skinny Phillips screws in the front.
      • 1 T20 security screw in the center.
      • The remaining screws around the perimeter.

Step 7: Test the Repair

  1. Check for Proper Assembly: Ensure all screws are tightened and the hose is securely in place.
  2. Power On: Plug in the vacuum and test to make sure the hose replacement was successful and the vacuum is functioning properly.

Conclusion

This guide should help you successfully replace the lower hose on your Shark NV 752 vacuum cleaner. Proper replacement can extend the life of your vacuum and keep it out of the landfill.

Reminder: Avoid using rigid adhesives and take care not to disturb the wiring during the repair process.
