It lacks a good little filter to catch fine particles because with what comes in all those particles are sucked in and then expelled through the back of the exhaust pipe making it pointless to use. Again, dust will collect in the battery compartment, which was made for items as small as impossible to clean. The service life is very short, only a few months with daily use. I have tried well since I bought 3, now I am very happy with something else, since everything is broken, I use a compact vacuum cleaner with a REAL filter, not a cheap mains, a lithium battery and a suction power several times higher than this vacuum cleaner is very inconvenient to use the ON-OFF switch. Stay away there are far better options, think about how cute it looks as it's practically useless as a vacuum cleaner, more like a cheap toy.
