I purchase the vacuum to replace a Hoover that be absolutely horrible . I be lean toward a Dyson -lrb- much to my husband dismay -rrb- . after much research and self debate , I choose this one . there be some assembly , but it be quick and easy . all you need be a screwdriver . yes its noisy , its a vacuum for pete sake and to address another comment about the weight , I be far from physically fit & I carry the vacuum up and down the stair without a problem . it do a great job . love the knob on the top to switch the suction from the floor to the hose . my only fault be that the hose it too short and a little stiff . I be glad I switch back from a bagless . the power paw be very useful on the stair and furniture . it have its own little holder that slip in right behind the handle . we have way too many animal and it leave my carpet fur free and clean . I also use it on my kitchen floor and it do a fine job . most vacuum blow stuff around . all in all , I be very pleased with my decision to purchase this vacuum and love the $ $ $ still in my pcoket .
