The Shark brand of vacuums never ceases to amaze me.  They are dependable, high end, and do a great job.  They are true work horses that are worth every Penny.  My new cordless Stratos is a great addition to an already outstanding line up of vacuums.  It’s a good weight, the battery charges quickly and lasts long enough for me to clean my entire home, and it does as great job on my floors!  I would highly recommend this vacuum to anyone in the market for a cordless vacuum.
