I am an avid robot fan, currently on my 2nd Roomba (very happy here) but now expecting my 3rd Scooba (not so happy here).
My Scooba story started with a 340 purchased at Costco about a year ago. I live in Sweden som I had to haul that succer on a long haul flight, but I was happy to do it. I think my 340 model lasted about 10 missions before it just wouldn't work anymore. I think I got to enjoy my 340 for about 5 missions when it started to fail in charging with 4 beeps from the Scooba. After contacting support they said 4 beeps was an unresolvable charger issue and offered a 5816 replacement. I always had concerns about this since it seems like the 5816 is very similar to the older 5800 models (and performance). iRobot always refuted these concerns and claimed it was a replacement code for a 340 - who knows.
My replacement 5816 met its demise in another strange way. After about 5 missions the robot wouldn't turn on after charging. The battery would charge the whole 3 hour cycle but when disconnecting it for a cleaning the ON button did nothing. Plugging it in again started some additional charging but after that it still wouldn't work. I contacted iRobot who said the robot was faulty and have issued another 5816 which I am waiting for now.
Being on my 3rd Scooba I have started to be ridiculed by my wife and her American family for being a naive lover of crap robot products. I keep thinking they just don't understand robots
But really I am also getting a little tired of the apparent quality issues with the Scooba. But what makes me have hope is that there seem to be quite a few other users with good history of the Scooba.
I must ask myself, am I doing something wrong? I try to stick to the charging routine recommended. Charge after every cycle and after charge store the battery outside the Scooba if I dont have frequent cleaning. In Sweden, were I live, we have 240V instead of the US 120 but I use quality transformers that I usually get from Brookstone which are 85W computer rated step down transformers. I use these transformers for my Roomba who seems to enjoy them just fine (for years). My concern is that maybe the Scooba charger is more sensitive? Another option could be that I have been unlucky in my Scooba replacements. I am not so versed in the physics of electricity but one difference from Sweden (and most of Europe) is that we run our power cycles in 60Hz whereas in the US its 50Hz - from what I have read this usually only affects motor with direct power feed like drills and a like but if anyone wants to chime in on that go ahead. However that is nothing I can change so hopefully it doesnt affect anything.
Hope anyone has some ideas or tips to share about my Scooba - I need some encouragement
