I search and search for a small portable vacuum that be very powerful and the Hoover unit be great ! I have a large cannister -lrb- expensive brand -rrb- that be difficult to move from room to room and get under furniture . this mighty little machine be just as powerful , the cord be extra long , great for hardwood , tile , or carpet . I buy this for all the hard floor surface but it would be great to use for carpet if you have a small condo . it have 7.5 amp and be double insulate . I buy two , one for the house and one for we rv . my best buy this year !!
