Very wasteful of your cash. Use Chinese knockoffs instead; they're just as effective, cost half as much, and are far easier to maintain and repair. After a year, Airobot's design started to seem ugly and ridiculous, and now I can't imagine not selling and using it. the benefits: Unlike prior models, this one operates quietly and cleans itself when docked. The downsides are: Ignorant vacuum cleaner software. Akum and its original spare components are unavailable, and the Chinese replica performs poorly during the particular procedure. It's a nightmare for the price because the map is drawn poorly and has recently stopped being cleaned up everywhere, despite the fact that the software itself functions well.
