Dyson V10 (SV12) main unit only. I cleaned it as much as possible. Eco mode lasts for 67 minutes or more. Medium mode lasts for 29 minutes or more. There are no functional problems, and it works normally. I don't think there's any noticeable odor, but please understand that this may vary from person to person. It has been disassembled and cleaned, but it is still a used item, so please refrain from purchasing if you are looking for perfection or are overly sensitive. Please purchase only after you are fully satisfied.
