Taken from a "robotic" fever, I bought one after another, in April 2014, the Scooba 230 (small) and the Scooba 390 (large). I must say that I was particularly pleased with the vacuum Roumba 770 of the same brand.
The Scooba 230: small, nervous, mat, (very) little autonomy and (very) long cooldown, ideal for small areas, I thought with relish ... a month. End of April; of fuel, exchange against a new one that, he just never wanted to start ... Return to Sender / refund / end of the experiment.
The Scooba 390: powerful, "shades of job," noisy but effective, a dream ... the first month. The first broke down "definitive" end of April (1 month), the second in mid-June (3 weeks), the third end of June (15 days). A fourth new today is in my possession; balance, I use both pétoche I spend BEFORE mop, sometimes that something (a dog hair, dust, mite) disrupts this remarkable mechanical imprecision. The interest of the matter remains, as we understand it very well, actually quite abstruse ...
I said that, for the two robots, I have always taken great care to respect the care instructions after each wash, my home has nothing exotic, he did not work more than two cycles per day (1 hour) and no failure was unlike the previous one, which says something about the range of possibilities and the remarkable imagination of these robotic cleaners ... Once it does not start, it grows again stubbornly and stupidly during 3/4 hour on the same wall perfectly straight, or, it works 3 minutes, it stops, and you must restart for 3 additional minutes of bonus, etc.
You will understand, buy these robots scrubbers reports to the challenge, lottery, money or suicide.
I think there was some commercial fraud from I-Robot to dare launch products on the market so expensive that they can not ignore the total lack of reliability. I think when these products will be developed - still provide a good few years - they will be really interesting to get rid of this chore that is washing floors, but for now it's just a shame to experience these robots (because we're well the experimental stage) on the client, not the factory.
From there to think that I-Robot takes its customers for guinea pigs, there is a step, I happily crossed ...
