It looks safe from super and is "to specify" - especially if you control it with remote control manually. And that was it for now with the benefits.
With carpets the unit has its "hands full". A 120m2 space with various carpets (tightly woven, heavy and significantly less than 1 cm height, otherwise "eats" it anyway at the edges or in the floor fixed or does not come "high"), the device does not create his battery to depart at once. Now is clear why they have the "photoelectric" settled for the fitting - additions to less use spaces to block (if one does not want to close the door) so that the battery lasts. Am looking forward when the battery gets weaker over time. Especially on a higher floor of carpet always are problems because the friction of the wheels on the floor is not good enough - because you want to go really mature from time to time, if it is "highly torments" on those edges.
Above all, the device has a problem to remember where it was. A systematic and cleaning strategy can not be seen, each time he drives the rooms from different. Certain areas with several square meters - with no visible obstacles - it cleans not often. Other places he goes, however, constantly three or even four times in a passage from. Sometimes it does not even capture the room right shank and moves at an oblique angle across the room, which in turn means that edge areas remain dusty.
Perhaps also the fact that this device comes from an Asian manufacturer, whose rooms are decorated differently but then European premises? "Who knows ...."
When clocking the device deliberately, where one stands in the way (which can happen when children and pets well) it loses sometimes completely the orientation and continues with schägen movements along a wall and "rummst" constantly against it. This happens sometimes with no "external influence". Once that's not very quiet, which is usually the moment you pick up it and into it in the charging device, because it is eventually only more annoying. The sensors are übrigends clean, because it can not be so.
In any case, does the "fall protection". We have a staircase in a room down, there it stops obediently without falling down. However, this has the result that he again has problems in this area, clean and completely to depart the area, because it is thereby clearly get confused.
2x it has happened, that he stayed down the middle of the suction across its own charging station and hang in there! In the state he then stops with appropriate visual and audible indication. I have already waited 10min safe and he has so far not turned off. So if you start the timer and is not part of my home, I would not be surprised that he there like a beetle stuck on the back until the battery is empty.
Oh yes, one more word to the light barriers. These are so "cheap" made that you can only switch on or off manually. In addition, the box run with 2 large mono cells, ie if they are not turned on before cleaning and then turns off, this one consumes unnecessary. But this is the "Timer concept" of the device superfluous. In the age of wireless networking and Bluetooth, one could already expect to synchronize these components using the timer control of the device and in between also can turn itself off (and only also enable front again - so a local timer can surely not be a problem, making any clock from the "bubble gum machine"). Summary: in the "Action", to use the device, you could also as "fast times sucked about it" ...
If the software is as good as the charging technology, I would not believe me anyway, to be driving around the unit alone in the room when no one is home. That would still be missing that a toy is a house "abfackelt". So he parked on a tiled floor without any inflammable objects near (apart from its own plastic case). And after I have to turn off the light barrier manually, I turn off the charging station when the vacuum cleaner is fully charged ...
Conclusion: For my former students 12m2 apartment with bed, wardrobe, table and 1 chair it would probably have been enough. Back then, I would have but can not afford to ...
I bought it to develop support, because I like the idea. And it is the present time according to a "Nerd Toys". Production-ready and in particular support for the 'normal' household is not the device safely.
After you have run after the part constantly because it is stuck somewhere because the chairs are too close so it gets through or because it again any wall "kissing away" because it has a problem, you would have the energy and the same time with a small "normal use "vacuum cleaner in hand and quickly sucked times the viewable surfaces ...
