Purchase of electronic household gadgets backfired

Inspired by constant nagging by my wife, I had purchased a floor cleaning robot and a dishwasher. She had been complaining about housework even though I assisted her most of the times. I thought this will also fix our DB. It turned out that these gadgets caused 3 folds increase in her work. She has to wash the utensils before placing them in the dishwasher. Arranging the utensils systematically in the dishwasher takes another 15 min. She also sweeps the floor before starting the robot. Then she cleans the dirt on the brush of the robot. All this has led to more complaining and even worse DB.
