This is a dishwasher but it also looks like a toilet brush. It is blue in colour, and it has a lot a lot of springs to wash of all the dirt from the dishes in restaurants. The springs are metallic.
Design Considerations: Needs a lot of hairs to wash off all the dirt from the dishes. It is made of plastic so that if it is accidentally heated, it would not burn the user's hand.
Elderly Difficulties? The elderly would face difficulties using this item. Because if the elderly's grip is weak, it will easily slip and fall onto the sink and the elderly would have to keep grabbing it off the sink. The elderly could scratch themselves with the springs.
The idea is the one below the original product.
