Housekeeper

We are aging (74 and 81) and need help with cleaning in our approximately 2800 sq ft home. We have 2 friendly dogs who love to leave their hair wherever they can so vacuuming is essential. For example, Im not able to vacuum our stairs. Its become too difficult for me to do. Ive had 3 back surgeries that have had an impact on my flexibility and strength. Cleaning and mopping our flooring is been difficult for me.
