I think Eufy should make a backpack Vacuum cleaner with an oversized battery. Since this goes on your back, there’s no requirement to make the battery small or lightweight. You can even go with a cheaper battery chemistry such as Lead Acid or Lithium Iron Phosphate (notice the word iron instead of ion). That way the cost of the increased battery size can be offset by an overall cheaper battery. I think you should target 25+ continuous minutes on the highest power setting. Any thoughts?
