MISTAKE
on May 26, 2026
Posted by: Ggoff1980

I purchased this product approximately eight months ago, and it has turned out to be one of the most regrettable purchases I’ve ever made. I sincerely hope that others who read this message will avoid making similar mistakes. Let me clarify that I generally have a fondness for Shark products, but this particular one failed to meet my expectations. The batteries in this product have an extremely short lifespan and tend to die quickly. We contacted Shark to send us a replacement, assuming that the issue was with the batteries. However, the same problem persisted with the new one. In hindsight, I genuinely wish that I had opted for a corded vacuum instead.
No, I would not recommend this to a friend.

Difficult to Use
on May 23, 2026

Am I Doing Something Wrong??
I was so excited to get this vacuum. The first brand name vacuum ive invested in. But this is the WORST?? Even on eco mode the suction is too strong to use on rugs (being too "good" was not what I expected) and immediately jams, blocking airflow, and turning off the rollers. This isn't able to be fixed without turning it off and back on, adjusting back into eco mode, and almost always getting blocked again immediately no matter how I adjust where I start.
Speaking of which, the button for switching between modes is directly under the index finger, causing it to be very uncomfortable to hold while trying to avoid this button. Holding it like this is also uncomfortable with it being too heavy to comfortably lift repeatedly to adjust positioning.
Uncomfortable positioning continues with the button to press in utilizing the multi-flex technology. It's placed with ease of manufacturing, but not for ease of use. An additional inconvenient "feature" is the "self standing" lock. Any time you get near 90⁰, the head locks into place and has to be manually corrected before continuing, but is not able to stand freely while in use due to the posterior wheels and weight.
I really want to love this vacuum for the self emptying and charging while docked, but every time I use this it just gets more inconvenient. Please help if you have any tricks, as I already discarded packaging.

Hi there,
Thank you for taking the time to share your detailed feedback.
We’re very sorry to hear about your experience, as this is not what we want for our customers.
From what you’ve described, the strong suction on rugs can sometimes trigger brushroll protection if airflow is restricted. Using a lower power mode and ensuring the airflow path and brushroll are clear of blockages may help reduce this. For rugs in particular, starting on a higher pile setting or slightly lifting pressure can also help prevent the unit from sealing too tightly to the surface.
We’re sorry to hear about the discomfort with the controls and handling. Your feedback on the placement of buttons, weight, and the MultiFLEX feature is important, and we will ensure this is shared with our product team.
For additional guidance and troubleshooting tips, please visit:
https://support.sharkninja.com
If the issue continues, we would encourage you to contact our support team so we can look into this further for you:

The best cordless vacuum I have purchased. I used to have a Hoover vacuum and the level of performance shank has given me in the last 2 years is beyond comparison.
I would recommend this to a friend!

It’s heavy and loud. The scent cartridge is horrible I wish it didn’t have to be used because now the smell won’t go away even when you take the cartridge out!
No, I would not recommend this to a friend.
