Thanks for the advises;
@ Jimson; thanks for the welcome and your experienced pro's and cons, very helpfull. What you describe is what I have read so far, although you seem quite happy about the amout your "Virgil" cleans, hehe. I have read many other storys that it doenst clean so well. interresting to hear.
We intend to use it in a large livingroom with a wooden floor. Normally we dont have much stuff lying around, so the issues of getting stuck we just have to find out for our selves (I guess it depends also on the way you live)... We intend to use it as extra help, we will not through Wilma (our normal vacuumcleaner) out of the window. She can stay and once a week or so pick up the left behinds of the Navibot (havent got it yet, so no name yet)
The costs in Netherlands for the 8855 are on internet around €400,-- which is expensive for a toy, but inexpensive for a fully automatic help in the household (you recognize the way I try to "sell" it to the wife, hehe
@ Jedyh; One of the biggest flaws I have seen with the Navibot is that "Sadie" cant run parallel with a wall. This is what puts me off and my biggest issue. I cant figure it out why they havent improved this. all other (neato, roomba, name them) have this feature. The navibot is well equiped with sensors, so the harware should all be there, it seems that the software is the problem. Perhaps an email to the Samsung R&D department will do the trick?
Regarding the comments on the gear; I have seen this on youtube for the roomba ( i believe the 581) aswell. I have seen a video where this guy mentions there is a small gap between the cover of the gear and the gearbox itself. This collects so much dust and hair that the gears (plastic with steel axes) clodded up with fluff and the gearbox actually also deformed / melted on certain places by the heat the fluff generated and the roomba rendered unusable. This seems a big design flaw of this model / productline.
@ piokrza; I have seen the neato on some videos, interesting robot. (doesnt look so good as the navibot though) but it seems to work very well. One problem for me, I dont think they are sold in the Netherlands though, ive already searched the web. They are not easy to get hold of overhere.
Ill see If I can make up my mind. Any other experiences are welcome.
Thanks and Cheers
