Bests & Worsts Reviews from Amazon

5 seconds into its very first use and the rolling brush grinds to a halt. Used on a normal medium pile carpet, a living room area rug purchased at Home Depot. Not made of lamb's wool or alpaca fur or lion's mane. Just, you know, a regular a$$ CARPET. I'm literally in disbelief that this product was allowed to leave the factory without the ability to be used on a very average medium pile carpet without complete, abject failure. The brush roller did work on a high traffic area of the same carpet, clearly indicating that it was the height of the pile alone that was grinding the brushes to a halt. Curiosity killed the cat, so I contacted SharkNinja. Their rep assumed I was an idiot. "You have to turn the vacuum on". "You have to flip the power switch to the powered brush setting". "You have to move the top from the perfectly upright position to engage the brush", etc. After waiting a few minutes on hold while the confused rep told her manager about my experience, it was reported back to me (get this): THIS VACUUM IS INCOMPATIBLE WITH YOUR CARPET. Wow. Would it not be more accurate to say: THIS VACUUM IS INCOMPATIBLE WITH CARPET? Or better still: THIS VACUUM IS INCOMPATIBLE WITH VACUUMING? Absolute garbage, and certainly the first vacuum I've ever used where my very average carpet failed to meet its exacting requirements for use. What universe is this? Returned. Buyer beware.
