ingests foam through the dome filter of the recovery tank it could damage the carpet and vacuum motors. Always empty the recovery
tank before this happens.

clogging the tip. Reattach the tip with the spanner. Make sure to position the tip opening so that it sprays side to side.
• After the carpet is completely dry, clean the area with your Mighty Pro X3® machine making sure to avoid overwetting the carpet.
Stains may continue to appear if the carpet is overwetted.

• Brush the spray tips with a soft-bristle brush, such as an old toothbrush, to remove any build-up that may be clogging the tip. Do not
brush spray tips with any kind of wire or metal brush. Do not try to unclog the tip by poking it with a pin or any other object. Check
