Aidyn actually really likes the vacuum cleaner. He also has an obsession with the mower, although wont get 'too' close to it when DP is mowing.
I think what helped him is that he has had a toy mower since his 1st birthday, which has a pullstring that makes a loud noise as it retracts back in.
He just loves anything that has a motor/engine!

Perhaps getting Zander his own fun push along mower or other loud toy may help him get used to the concept?
