After trying this product, I've determined it's a complete waste of money. The suction power is practically non-existent, making it useless for any industrial and scientific cleaning tasks. The size of the vacuum is also deceivingly small, making it difficult to clean larger areas efficiently. The only positive thing about this product is its lightweight design, but that is far outweighed by its lack of usefulness. Do not waste your time or money on this subpar vacuum.
