Buying Guide: Key Considerations for 4-Gallon Wet/Dry Vacuums
- Power vs. portability: Higher horsepower improves suction but may increase weight. Choose according to typical mess type and mobility needs.
- Tank material: Stainless steel lasts longer and resists denting but can weigh more than plastic. Plastic tanks are lighter and budget-friendly.
- Filtration: Reusable cloth or foam filters suit dry and wet tasks differently. Look for washable options for lower long-term costs.
- Accessory versatility: A wide nozzle set, crevice tool, and brush attachments expand cleaning capabilities for cars, workshops, and upholstery.
- Reach and storage: Longer hoses and cords improve reach; consider onboard storage for accessories to keep setups tidy.
- Blower function: A built-in blower helps with leaves and dust piles; however, ensure dust control with proper filtration when using the blower.
