Pulls air well - noisy in the process

It does pull quite a bit of air! Noise started up about an hour I started using it (resonating sound). You can press in on the motor and the noise stops. Good construction otherwise.

Probably cleans air well, but it is TOO NOISY to keep on at night, even in the "quiet" night setting.

This thing works great on my couch to pull up cat hair periodically, but air blows out pretty forcefully out of the side. If I try and use it on my hardwood floors, it is more likely to blow the cat hair into the air/around the floors than to suck it up. If I can contain the wind tunnel it creates, it does a great job. In the end it cleans what I bought it for (the couch) so I'm still happy with the purchase. And it's pink, which I like.

Build quality is very good however even with in Q (quiet} mode the unit is very noisy . To get any noticeable air sucktion one has to go 2-3 levels higher at which point the noise level becomes unbearable.

It moves enough air but only about 60% as much as the totally silent fan that came with my E3D clone.

I could live with the air flow as the temps are fine, but it ain't quiet. It has quite a shrill little whine to it. When printing, the noise is acceptable with everything else going. But, during the cool-down where it is the only thing running (I have cutoff st at 50C) it is VERY annoying. Like being in the Dentist's chair. :)

I could send it back, but I have soldered connectors to it so  will order another brand and try again. It did draw the claimed current, 0.84A and hovered around the 0.99W and 1.05W mark.

It's a bit noisy, but it does a great job. The hose is super easy to detach for when you want to use the on-board tools. Just press a button and it comes right out! That may sound insignificant to some, but with my old vacuum, I had to wrestle the darn thing to get it out. The tools snap back into place securely very easily also. (I could never get the tools to stay in place on my old one!) And of course, the bonus is the retractable cord, a feature I was not going to live without anymore. It does seem a bit noisier than I would expect. In fact, it actually seemed noisier the second time I used it. That is my reason for only giving it four stars... I may upgrade my review at a later date, but I want to make sure it continues working.

This product works well and as advertised, and my cat likes it OK - but it's so noisy that I have decided to return it.

Easy to set up. Easy to fill and operate - just plug it in after installing the filter and filling with water. Well designed (except for the noisy pump/motor).

But it makes a constant, rattling buzzing sound which can be heard throughout the living area of my apartment. I thought a part might be loose on it, or it might have been cracked in shipment, but no. Then, I thought maybe I could get used to the noise. No good, so its going back.

These things move good air but are a little loud for my liking.  Overall a good product.

At full speed, it's reasonable noisy - just the sound of air flow - no mechanical noise. But, at all other speeds, there's mechanical noise (rattles, buzzing) which is loud enough for other people to comment on. Perhaps I could disassemble it and grease some bushings.

While I do like this fan, I wish it was a little more quiet. It's not loud but it does make the noise a fan noise. It does push A LOT of air considering how small of a foot print it uses. The optional Oscillating feature is awesome as well.

It cleans very well but it is noisier than I expected.

This product definetly moves air.  I was expecting the fan to be loud becuase it is the performance edition.  I wasn't expecting it to constantly rattle and sound like an old hard drive being stressed to the max.  If all I heard was air moving I would give a 5 star review.  The rattle drove me nuts and I ended up adding pressure to the middle of the fan to stop the extra noise.

As above.

It is freaking noisy though!!!!!
It does blow off some kind of oil mist when working that you probably don't want to breathe.

Although it is noisy, as expected, it is quieter than my previous large fan. It works wonders to pull air through the house.  I'm thinking of getting another one for outside.

Moves air greatly with H to L switch, its kinda loud but the rig i put it in was already load so barely heard it at H.

This hand vac is powerful, and sucks debris in easily. However when it is time to empty it, the filter assembly resists coming apart without lots of effort. I have had two of this model of Hoover hand vacs<a data-hook="product-link-linked" class="a-link-normal" href="/Hoover-S1120-Hand-Held-Wet-Dry-Hand-Vacuum-Cleaner/dp/B000981H6O/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Hoover S1120 Hand Held Wet/Dry Hand Vacuum Cleaner</a>, and both have this problem.

Works very well, although it is a little noisy.
