I think its all bollocks , they are only good for repetitive tasks.
How about this then. Get a human to sweep off the patio, get the power washer out of the shed and give the patio a quick blast, put the power washer away not forgetting to empty it of all water, get a spanner out of the workshop to swap the gas bottle over on the barbi and bung the empty in the back of the car. It would take a human half an hour tops for that lot , it would probably take a geek a year to program one of these metal mickeys to achieve part of the task. I think and pray we are safe for the minute.
