The eVac has been off of the market for at least 4 years. I finally have a review ready, as I received a eVac recently.

From looking at the eVac it looks like a normal robotic vacuum that will clean effectively. I have found it does miss some spots and overclean some areas. I would suggest a Roomba to go along with your eVac because you need to have the Roomba vacuum after eVac is done.
It has Soft/Hard setting to accommodate floor surfaces. I always use hard as this makes the battery (which is very short lived, only about 20-30 minutes) last longer.
The battery is a NiMh 12V 4.5 AH Rechargeable. It is very short-lived. Mine can usually not last more that 15 min., but I keep the eVac because I don't want someone else to tire of it then throw it out. I only use it for entertainment.
It has 3 timer settings, 15, 30, and Max clean.
The eVac has several modes it uses to clean the floor: S shape, room crossing, and 3 types of wall following. I repeat: 3 types of wall following. :o
The eVac comes with 4 traffic cones to block off areas that you don't want it to go.
It also comes with a RF remote. This is extremely useful to get the eVac out of under a table when it is done. It also allows you to turn off the vacuum only for manual driving.
TEST
I have tested the eVac on paper punches as recommended here.
I turned it on and it played a cheerful tune. Then I used the remote to drive it over the punches on the hard floor setting. It cleaned up every last one on the first try.
I tried it on industrial carpet on hard floor setting. Same results: every punch is picked up.
The eVac has found a lot of dust/debris even though it only cleans hard floor. I have found it also has some sort of confetti supply. When I go to clean it, I always find a piece or two of confetti in the dustbin.
I would overall give the eVac a 8 out of 10. It is almost perfect, but it does need a little more work.
Hope you like the review!
