We need a new vac in the next few months as well. We have one on lend from friends that went overseas that are returning soon!
I've heard excellent things about the robots from friends who have purchased them, however they all say you really need a normal vac as well. The robots don't do a deep clean, they do a light clean everyday. Plus what if there is a spill of chips or whatever on the carpet. We have stairs with carpet on them as well... A robot is on the list, but for a while after we buy another normal vac.
The vac we have on lend at the moment is a Wertheim. Definitely like it, but hasn't dazzled me enough to just blindly buy another one. I'm keen to try something else if research and recommendations say so.... So thanks for starting a thread!
