Sharks may be good performers---but for how long??when the belt wears out or breaks in the powernozzle you are forced into buying another nozzle-if you can get one-or a whole new machine.No thanks.Would rather have a quality bagged vacuum that can last you for YEARS and changing the bag only takes a moment and you don't get dirty-and no messy filters to clean!!I see too many dead sharks in the vac shop dumpster out here!Helpted the store operator clean out his junkpile-guess which is the most common vacuum in that pile---Sharks!!!They makes such a satisfying sound when thrown into the dumpster!
 
IN the little video clip--those filters!!!!As I say before when folks out this way buy a vacuum-Dysons,Sharks,whatever--the owners book is thrown in the garbage with the box.So the user is unaware of those filters that need cleaning or replacing.See MANY of these vacuums taken to the vac place out here--the user says--"No longer picks up" you find the powernozzle neck is clogged,filters plugged up,and in a few the motor is burned out.The relief won't save the motor-when you hear it come on-you have to dump the bin,and clean,replace those nasty filters.-even the HEPA one!Too many folks since they didn't read the book-they use the machine like a bagged vacuum and dump the bin when it gets full-proper use of ANY bagless machine requires you to dump it after EACH use.And the screen in the cyclone needs cleaning too,after each use.It WILL clog!Usually the clog is due to long dog,cat or people hair!
 
I work in a shop, they come in all day long, only about 50% we can fix. On many models, NOTHING is available in the way of replacement parts. The engineers over at Shark even figured out how to make the brushroll motor overload protection circuitry a big mess, instead of a simple circuit breaker like Aerus/Electrolux has used since the 1950s in the PN-1, they have a board with a full bridge rectifier, a mosfet, and other crap to drive the LEDs. This is an AC 120v motor, it is ridiculous. We had to figure out how to bypass the board if necessary to get the cleaner working. If you bust a plastic latch on the bin, it is game over, they don't sell new latches, your only hope is that some local vac shop has a bunch of Sharks laying around to rob parts from.

Get a Sanitaire S634 you want a lightweight upright that will last. Probably lighter than the Shark, and easier to use, too.
 
I have 2 Shark uprights. NV500 and NV340.
They perform better than many would expect and maneuverability is excellent.
I really like using them.
However motor tone is very high pitched. Especially in the NV340.
Well picture says more than thousand words.
Motor is incredibly tiny.
It runs extremely high rpm and puts out a lot of heat. Can't be good for the lifespan of the motor.
