Solved this 3 years ago with a new battery and I’ve ordered another. I’ll clean the octopus legs just in case but sure it’s the battery.
Ive no complaints with 2 to 3 years Per battery, just wish Dyson let people know. The on - off quick cycles are confusing and I’m sure many have ditched their Dysons in frustration.
i fix it when my wife says it’s broken. Doesn’t slow down like battery power tools.
My wife loves the vacuum.
