My Cordless Blower Vac is losing power

Overview

If your Cordless Blower Vac is losing suction or blowing performance, the most common causes are a low or weakening battery and airflow restrictions caused by blockages in the tube or collection system.

This guide explains how to check the battery, identify airflow restrictions, and safely clear any blockages to restore normal performance.

Step-by-Step Guide

Step 1: Check the Battery Charge

• Ensure the battery is fully charged before use
• If performance drops during use, remove and fully recharge the battery
• Confirm the battery is correctly inserted and locked into place
• A loose or partially fitted battery can cause intermittent power loss

Step 2: Check for Blockages

Inspect the following areas carefully:

• Suction tube for leaves, dust, or debris
• Blower outlet for airflow restriction
• Collection bag (if fitted) for clogging or overfilling

Remove any visible obstructions that may be restricting airflow.

Step 3: Clear Blockages Using the Lever Method

⚠️ Safety note: Always wear protective gloves and safety goggles before carrying out any clearing procedure.

To clear blockages:

• Remove the collection bag (this is required for safe clearing)
• Set the machine to maximum speed (setting 5)
• Locate the black lever on the left side of the unit
• Move the lever back and forth repeatedly
• Allow airflow to dislodge internal debris naturally

Step 4: Manual Blockage Removal (If Required)

⚠️ Safety note: Always remove the battery before performing any manual inspection.

• Switch the machine off completely
• Remove the battery from the unit
• Carefully inspect the tube and internal housing
• Remove any debris using gloves or a suitable tool

Do not use sharp objects that may damage internal components.

Step 5: Reassemble and Test

• Refit the collection bag if required
• Reinsert the battery until it clicks securely into place
• Start the machine at a low speed setting first
• Gradually increase to speed setting 5 to confirm full performance

Frequently Asked Questions

Why does my blower vac lose power after a few minutes?

This is usually caused by a partially discharged battery or airflow restriction due to blockage or a full collection bag.

Why does the machine feel weaker on higher speed settings?

Check for debris in the tube or collection system and ensure the battery is fully charged. Reduced airflow is often due to partial blockages.

Do I need to remove the collection bag to clear blockages?

Yes. The bag must be removed before using the lever clearing method to allow proper airflow.

Can a dirty filter or bag cause power loss?

Yes. A clogged or full collection bag will significantly reduce suction and blowing performance.

What should I do if power loss continues after cleaning?

If the issue persists after cleaning and charging, there may be an internal airflow or motor fault, and the product should be inspected by technical support.
