The little prodigy could deserve 5 stars as it is effective to dislodge any dust and swallow, but perfection is not of this world there are some mini flats to report: rather noisy, so light and compact that it sometimes returns, its main brush and the handle are too heavy and too large for its small size. Note as well as maintenance request regular care that requires a normal life. Still I recommend it to anyone that repels dust, it is perfect.
