A couple of months ago my machine would turn off after a few minute of use. I called Dyson and the tech ran me through some steps and said it was the main unit while I thought it was the battery. I purchased a new main unit. It worked for some time and now I have the same issue. It stops after a minute of use. I have tried for more than a week to get someone on the phone without success. The wait times are 60 minutes without a call back option. I tried the automated text method that said it was the battery and that someone would contact me in 24-48 hours which did not happen. If it is the battery, I don't think I should pay again when I was told it was the main unit. This is the worst customer service experience that I have had in a long time.
