In general, a handy thing for hard-to-reach places, and does not take up much space. If you want to use the place wisely, and not litter it with healthy vacuum cleaners, this is an option. But the main thing I have is a robot vacuuming - I trust him more. This is purely so, for support in critical situations. Got pros: Comfortable, does its job. The sofa was cleaned well, window sills, tables, cabinets - vacuumed from debris. At corners, on skirting boards, in hard-to-reach places - convenient and mobile. How long the question will last, of course, but in general, if you do not load it, I think for a long time. Cons below: The charge does not hold for a long time of course, for a long time I did not vacuum it. Purely so, a couple of minutes to vacuum the sofa, or the table, or the garbage from the cat. But it depleted quite quickly.
