Bests & Worsts Reviews from Amazon

I purchased this vacuum on Prime Day in June 2021. I did not realize that it was sold by Woot (which is still part of Amazon, but not directly Amazon). The vacuum arrived and worked okay- the suction wasn’t great but I’m vacuuming hardwood floors and low rugs so it was fine. Last week (less than two months after purchasing the vacuum, August 2021) I charged the battery overnight. I turned on the vacuum and it only worked for a few minutes (the indicator on the battery showed it was fully charged before suddenly flashing the red low charge light and shutting off). I followed the trouble shooting advice on Amazon’s website and on Eufy’s website. I saw that I missed the return window by two weeks, but Amazon did give me Eufy’s contact info. The customer service rep for Eufy’s online chat was very helpful and told me they would send me a new battery if I just emailed them proof of purchase and my shipping address. I emailed Eufy the required information, but the email customer service started asking for more proof. I have sent videos like the one I attached to my review demonstrating that the vacuum does not work. They keep asking for more demonstrations and more proof as if I am lying. I called Amazon, who connected me back to Eufy/Anker. The phone customer service rep for Eufy promised me a refund after I provided all the information that I had already given the chat and email reps. Days later, there is no pending refund in my account. I have now received another email from Eufy asking for more proof that the vacuum doesn’t work, this time they want me to prove that the suction isn’t that good. I have told them repeatedly that if Amazon would let me return this vacuum, I would. I would buy a different brand. I have several Anker power banks and charging cables, and thought highly of the Anker/Eufy brand before this vacuum. I do not recommend this vacuum and would caution against buying any of their other products after this incident.
