Key takeaways
- Tank size: around 5 gallons suits cars, spills and home jobs; 9 to 12 gallons suits workshops and big clean-ups.
- Check the filter: fine dust from sanding or drywall needs a good cartridge filter (HEPA-rated if possible), and wet pickup needs a filter that can stay in place or a foam sleeve.
- Hose length, a blower port and the attachments included decide how useful it is around the house, garage and car.
