This charming to our small robots but he constantly bears not the thought in that sucking is a waste of time and one that could even save (as I did), but it burns almost sure to be its application requirements. He is the insatiable Pac-Man, which his feeding tour starts on your home turf, while able to destroy as dirt, dirt, hair and other debris oodles its life annuities and stomach food and this hunt, in contrast to most of the people at all hours to grumble or night without receiving! :)
Our Robo-mate is certainly not perfect: He expects from its owner a little legwork, he should swallow all dirt reliably. The Roomba places like eg with loose cables lying around on. Although it can be exempted by its intelligent anti-Verfang- system almost always themselves. For particularly thin cables it comes then but occasionally diplomatic "tangles", which can then only be eliminated through the judicious placement of a humanoid again. Caution even with very light carpets, as I have, for example, in the bedroom and the rest just loose on the laminate. The Roomba stops here none of it to run over them, but pushes this wimps who are able to bring against him does not provide sufficient resistance, easy to tangle together. Better: Before vigorously shake out and then put away!
The same applies to sensitive pieces of very dark material or chrome, or in principle everything the infrared beam of the Roomba poorly reflected. Normally, the Roomba is very gentle on the furniture. He recognizes them in a few centimeters away, then lowered his awesome speed, this anzutitschen gently. For objects, however, reflect the infrared beam only bad mutated Roomba to Ruffian: With full speed the monster thundering against my black furniture or against my chrome floor lamp. So the lad already weighs a few kilograms, advised there ever a few parts to wobble. :)
All in all, keeps the Roomba but what it promises: He left me with five rooms to suck (including bathroom, hall, kitchen.). I prepare the apartment robot righteous before (all the obstacles out of the way and places freely, where the Robi au should also suck definitely), press the Clean button, leave the apartment and find the Roomba later exhausted but gorged in its cradle before.
Speaking gorged: As everyone knows, has what is incorporated to at some point get out. So also with the Roomba. Instead of changing the dust bag, there is here a bag-less system, which is very easy to clean, but dust allergies quickly brings it into contact with the dust, you have to be aware. Nevertheless, all parts, incl. Brushes, wheels, very easy to clean! This really is ideal solutions!
Conclusion: Of course it is always somehow better, but in the current state of the art is the Roomba 620 for its price a good performance ready. I am always amazed at how much dust and dirt, he still takes, if I really thought that the floor is actually quite clean. Since I often because of pain not'm for health reasons will be able to suck himself, this little helper to me has grown really fond of! Buy recommendation!
