Dear Dyson, I purchased a V8 in March of this year it very soon failed to last very long but has got progressively worse.

We have run a few trials and now find that making sure it has a full charge, wait until the blue charge light extinguishes it only operates for around 6 minutes.

I have reported this and was initially told I would receive a replacement battery. I now understand the battery is out of stock and the order for the battery has been cancelled. I was then sent a message stating that the machine would be collected on the 11th November. I contacted Customer Services by phone but was told I could cancel the return and wait for when the battery returned to stock. I am unwilling to return the machine as I understand it will take 7 days to repair and return. The machine is our only form of vacuum cleaner.

The conversation with customer services was pointless as they listened to my concerns but could offer no solution. You do not have field engineers. The reason I replaced the unit was because my SV05 developed a faulty head, and you could not get a replacement part.

In my opinion the machine is not fit for purpose and should be either replaced or the purchase price refunded. Should I contact Trading Standards.

Please provide a solution that enables me to restore a fully functioning machine that meets your performance specification.
