This Rocket replaced a Black & Decker 20V “Pivot” handheld cordless (BDH2000PL) which lasted only 26 months in light use.  The Black & Decker replaced a Dyson handheld (refurbished) which lasted almost 36 months.  The Rocket is quieter then both of the others.  It seems to be as powerful, if not more so, but I have no way to quantify that.  The Rocket is about as ergonomic as the Dyson to use with the short nozzle,  much more so than the Black & Decker, which had a short nozzle, even with the extension pulled out. Also, the Black & Decker’s nozzle was wide, so it did not get in corners well.  The only downside that is readily apparent with the Rocket is that it does not come with a charging cradle and Shark does not sell one as an accessory.  I put a 25-lb. capacity utility hook in the closet near where I had mounted the other two vacuum’s charging cradles.  I always put the chargers on a timer so they don’t charge while we are asleep (worse case scenario precaution).
