Anyone who presoaks laundry knows the problem. You fill the washer with clothes, laundry and soap - with the intention of starting the laundry after 20 minutes of soaking. Two days later you remember it's in there. Jitendra Tailor decided to solve this problem for once and all with an automated presoak system. With Tailor's gadget, you only have to cut one wire in the washing machine - the one that goes from the lid switch to the pull on/push off module. Attach the gadget and presto, no more forgetting about your laundry.
