I have two cordless Dysons, bought 4 years ago.
The plug one one of them makes Apple's lightning cables look incredibly durable and the other just broke two weeks ago. Red flashing lights - looked up what that meant in the manual and just means it's buggered.
I hadn't started googling yet as we just use the downstairs one around the whole house now but I've heard good things about the g-tech from a colleague.
