Husky Power Washer Looks simple, but really complicated Internet

Every time I go to use the Husky Powerwasher 1550 it takes a long time to get it to work.  First, to attach the hose without scraping your knuckles will be a miriacle.  Why can't the connect NOT be indented into the body of the machine.  I'm a woman with medium size hands.  I can't imagine how a man will be able to attach the water hose.

Second, it take much back and forth to jus get the water and motor to run at the same time.  Then, inevitably, the GFI will pop, even though I have no problems with other outdoor equipment. 

Today, I spent two hours trying to get my pressure washer to work -- it finally did -- for two minutes only.  Then another half hour of re-reading the troubleshooting section on their website and nothing.  I quit.

Why can't someone make a simple pressure washer with a simple hose attachment and a simple push button to start.  We can send people to outer space and robots to Mars, yet a simple outdoor applicance is elusive.
