2. Using Attachments
The WDA320J-QW comes with two primary attachments:
- Extendable Crevice Tool: Pull out the crevice tool from the front of the vacuum until it locks into place. This tool is ideal for reaching tight spaces, corners, and between cushions.
- Flip-up Brush: Flip up the brush attachment located on the front of the vacuum. This brush is suitable for dusting delicate surfaces, upholstery, and for loosening stubborn dirt.
3. Wet and Dry Vacuuming
This vacuum is designed to pick up both dry debris and liquid spills.
- For Dry Debris: Use the vacuum with or without attachments to pick up dust, crumbs, and other dry particles.
- For Liquid Spills: Ensure the dirt bowl is empty before vacuuming liquids. The vacuum can pick up small liquid spills. Do not immerse the vacuum in water. After vacuuming liquids, immediately empty and clean the dirt bowl and filter to prevent odors and mold growth.
