Why does my cordless Dyson only work for 3 minutes?

I love my cordless Dyson DC 59 which I bought 3 years ago. It’s lightweight, convenient and has great attachments. But recently I have not loved it.

Every time I used it, it would work for three minutes and then cut out, the flashing orange button telling me it needed charging.

This couldn’t be right. It is charged all day so what was going on.

Very simple ( and I feel very stupid that I had not realised). On the head of the vacuum is a large circular button that says MAX. This was lit up in blue every time I held the trigger down. It shouldn’t be. This is the boost button for when you need extra power. Keeping this button operational all the time depletes the battery (obvious) and makes the motor very hot!

All I had to do was push this button in for a second, when holding down the trigger, and the blue light went out. Normal power was resumed and vacuuming now lasts at least 15 minutes.

Thank you Beth at livingwithbeth.com. Her site alerted me to the problem and she has some other top tips relating to the Dyson.

Happy vacuuming!
