This is the Second time I have purchased this vac from Black and Decker. This is a great model. I have used cordless handheld vacs my entire life from when my mother would put me to work cleaning the steps and the kitchen floor with a "dustbuster". and this pivot vac from Black and Decker is the BEST i have ever owned. This model with give you Great power to get your entire job done. It has never run out our power on me while doing a job. full strength suction until the job is done. Very easy to empty... and you can even take it apart and run it through the dishwasher. i love the pivoting head and the dust brush that just flips out... and did i mention the crevice tool that extends easily from the tip of the nozzle head. this unit is great and the last one was so reliable and performed so well that after 4 years of service from the first one that we bought a new one. i highly recommend this vac!
