i am old , my old unit was simple to use , push a button and it cleaned until battery went low --- this one has settings for time date for each day -- i tried to set it and it starts EVERY day. but i don't need it to sweep every day ---- i guess i just like simple and this one isn't , for me!!! now , does it do a good job YES fantastic ,, just like my old one -- this one, for my old brain is too complicated
This Roomba is a new addition to the family. We have two other exact ones. It performs well. They all have their limitations, but this model is the best bang for the buck.
