Please suggest a good dishwasher, handheld vaccum, and robot vaccum

I work night shift, have been taking househelp's support to clean my living space. Tired of requesting all the househelps Ive changed so far to clean the dishes well. They clean the water bottles, but i have to show them how to clean inside the cap. Coffee mugs have stain and i wash it again after they wash. Its the same problem with everyone. Is there a good, stain-removing, suitable for Indian-cooking dishwasher that you'll recommend for small spaces? Also, pollution and dust has been impairing my life these past few months. Any suggestions on a good quality handheld vaccum/ robot vaccum is also welcome. Thanks so much in advance!
