Here's our floor plan:
The whole area is 96 square meters, but the sauna area takes about a third of that (on the right), leaving about 70 square meters for the living quarters. I usually keep the office and bedroom door shut, which further brings the cleanup area to about 50 square meters, or about 550 square feet. With the dogs dropping so much hair, we like to keep it running every weekday. It really helps keep the dust in check. If you don't have animals inside, it doesn't need to run as often. I think it takes it between 1 and 2 hours to do that, but it needs to work around a lot of obstacles with the way our layout is set, and the furniture makes for some obstacles. With more open spaces, it's quicker.
The reflective surfaces are a problem, because it uses a laser radar to map the space it moves in, and it gets confused with shiny metal, mirrors or things like motorcycle helmet visors.
Oh, okay.
Wow! Great graphic!
Thanks for the info. We have one dog inside, but all the children who live here are a bigger mess than she is.
Oh, we don't have reflective surfaces. There's a foam mat in one of the bedrooms, there are two rooms with rugs, and we don't have a lot of obstacles, so this is something that sounds like it could work well for us! I've got to talk to DH. =)
Oh, does it kick up dust like a regular vacuum cleaner does on hard floors?
We have a Roomba. The grandson's ferret was out and about the house and I heard the starting tone. He was standing there looking amazed. As soon as it started backing out of the dock he ran into the adjoining room. It followed. I walked in just in time to see him standing in the hallway peeking around the corner obviously puzzled about this monster. The moral of the story is that even a ferret can do the housework woth one of these.


Go for it. You might be able to break a record.
I think I have the record on this thread with six posts in a row.
I'm too lazy to do the finger work to find out though.
