Vacuum shows F1 and suction is significantly reduced; filters icon may flash.

Safety first: Turn OFF the vacuum and remove the battery before handling filters.

• 1. Remove pre-motor filter: Open the dust bin or filter cover and take out the foam/fabric pre-motor filter.
• 2. Clean or replace: Tap the filter gently to remove dust. If TCL allows washing, rinse under lukewarm water until clear. Do not use detergents unless specified.
• 3. Dry completely: Air-dry the filter for at least 24 hours until no moisture remains. A damp filter can trigger F1 and damage the motor.
• 4. Reinstall correctly: Ensure the filter is seated flat and the cover is fully closed so that air passes through the filter as designed.

Note: If the filter is torn, deformed, or permanently clogged, replace it with a genuine TCL pre-motor filter designed for your model.
