Query: decent but not up to expectations

Compared to other handheld cordless vacs, it is very good.However, the Shark's claim of being powerful and quiet is highly exaggerated. The vac worked fine for the first few months, but the motor seemed to lose a little power and after a year of use the suction power was mediocre at best. You will need to empty the bag constantly and keep it fully charged for it to perform well.Also the round shape of the vac is a major design flaw, the "snout" of the vac is so broad and blunt with the opening of the vacuum so small it was hard to get into corners unless you use an attachment.The charger is also another design flaw, it is often hard to dock the vacuum in it and doesn't fit so well.It is also noisy, it's not terribly loud, but it produces an annoying whiney higher pitched sound.Generally, cordless vacs are not the greatest in terms of performance and longevity, but if you must get one and don't have much to spend than I could recommend this vac half heartedly.
