Hmmm... Nice indeed.
That head to head video says a lot for me...
I am uncertain whether these are biased head to head reviews exploiting some advantage this has in particle size or weight of items
I wouldn't think that rice was weighted or somehow made more difficult to pick up for the LG & Samsung
It is quite obvious that the LG mostly just bulldozes the rice across the floor, (I have heard it has vitually no suction power, but I cant find any specs on that for either model anyway) I would have thought it's main brush would have more effect. I know suction power only plays a small role in the effectiveness of a Robot vacuum, and I see that according to Yujin Robot http://www.iclebo.com/english/
iClebo Arte's main brush spins at 816 times per minute (almost 14 times per second) I also see that they quote results on a Sand test as Arte having 89% pick up compared to an average of 54% for other brands. (the test is stated as being to an International test stanrdard) (I guess some would claim that they might be lying)
In that video he Samsung looks like it picks up nearly
as good as the Arte, but, seeing that the Samsung gets stuck easily and definitely does not negoitiate the area or obstacles anywhere nearly as well as iClebo Arte, (and that the one Samsung I have seen operating was so loud) it is a no brainer for me.
I don't expect the LG to be perfect
I am sure we can't expect any Robot vacuum cleaner to be perfect, now or even in the future either, especially considering that every home environment is going have it's own unique circumstances with furnishings, layout and design.
I am going to buy Arte in coming weeks and will give my own honest
opinion here some time after that.
