Robot Vacuum

I am 85 and I suffer from dizziness so that I have to hold on to something when I walk or turn around. I use a cane or a rollator/walker when outdoors. But vacuuming is very difficult and tiring if you have to use the other hand to keep balance.
The robot vacuum cleaner that I bought a week ago is my rescue. I can have it vacuum the whole place or just one room whenever I want to.
