How to Replace the Filter on Your Powersonic HH400 Cordless Vacuum Cleaner

How to Replace the Filter on Your Powersonic HH400 Cordless Vacuum Cleaner

Keeping your HH400's filter clean is the most effective way to maintain strong suction and extend your vacuum's life. We recommend checking the filter every 4–6 weeks and replacing it every 6–12 months depending on use.

What You'll Need

Step-by-Step: Removing the Old Filter

  1. Switch off and unplug your HH400, and remove the battery for safety.
  2. Locate the filter compartment — on the HH400, this sits at the top of the dust cup, behind the release button.
  3. Press the release button and twist the filter anti-clockwise to unlock it.
  4. Pull the filter out gently. You may see a build-up of fine dust — this is normal.

Step-by-Step: Cleaning a Washable Filter

  1. Tap the filter gently over a bin to remove loose dust.
  2. Rinse under cold or lukewarm water — never use hot water or detergent as this can damage the filter media.
  3. Squeeze gently and repeat until the water runs clear.
  4. Allow to dry completely for at least 24 hours before reinserting. A damp filter will reduce suction and can damage the motor.

Step-by-Step: Fitting the New Filter

  1. Align the new HH400 replacement filter with the filter housing.
  2. Push in and twist clockwise until it clicks into place.
  3. Reattach the dust cup and reinsert the /products/replacement-battery-for-hh400.
  4. Switch on and check suction — it should feel noticeably stronger if the old filter was blocked.

How Often Should You Replace the Filter?

Light (1–2x per week) Every 6–8 weeks Every 12 months
Regular (3–5x per week) Every 4 weeks Every 6–9 months
Heavy / Pet hair Every 2–3 weeks Every 4–6 months
