I was shocked at how powerful this hand vac is. The charge lasts a long time. I was so impressed it is my plan to purchase another one. I tossed out the other two I had which could not light a candle to this vac. It is really wonderful to have the attachment to vacuum corners attached in addition to a brush you can push out to make vacuuming crumbs easier. I LOVE IT! Maneuverability Ease of use. Ease of Maintenance Very powerful! I have owned several through the years and nothing compares. Suction Performance Great suction! Versatility Versatility is better than any other hand vac I have owned. Design The design is unique in that it has the attached crevice tool to use whenever necessary. All you do is flip it open and VOILA! Durability No problems with durability although the housing appears to be plastic.
