Trained dogs might just be the proof that they really are men’s best friends not only because they can fill laundry baskets, but because they can now use washing machines with just a simple bark.

Thanks to the new washing machine —--- the ‘‘Woof to Wash”，a lot of people can benefit from the invention, which enables trained dogs to unlock the machine with a footpad and start it with a simple bark. A doggy footpad and a microphone system have been added, which can recognize a dog’s bark，which means that dogs are able to unlock the machine by pressing the pad with their paw, pull a rope with their mouth to open the machine, and close the machine again with their nose, before starting the washer by barking.

Dr. John Middleton is a great inventor. The disabled owners who are blind or have autism (孤独症)problems or learning difficulties, can’t use the present-day washing machines. So he thought there’s a lot of demand for the new washing machines to make things easier. Then he saw a video from the charity Support Dogs, where a dog makes the bed and loads the washing machine. He was completely blown away by the video at that moment. He was inspired that he could invent a machine which the dog could operate. Mr. Middleton said, “I’m happy I saw the video. A normal washing machine can be very challenging, so the single program machine is very helpful. But a lot of people also have speech problems, so a voice-activated machine is handy. ’’

The Support Dogs charity was set up in 1992. Dogs are trained here using voice commands and hand signals, so that they can help their owners fetch post, turn on light switches, open doors, assist in dressing and undressing, as well as do a complete laundry cycle. It has trained over 200 dogs to date throughout the country and relies fully on volunteer donations.

We hope the new washing machine can help more people. And we sincerely welcome the sponsorship of any type of business which is kindly willing to help. If you would like to sponsor, please contact us!
