Ehoyal Computer Vacuums Cleaner, Keyboard Cleaner & Blower Cleaner 2-in-1, Handheld Cordless USB Rechargeable, Portable Mini Vacuum Easy to Clean Dust (Silver Grey)

I initially purchased this device to clean a one month old gaming computer rather than using just canned air to blow dust everywhere else into the room. This little vacuum did pretty good on anything that was dust and such. It's probably not going to extract crumbs from deep in a mechanical keyboard so you'll still need something to dislodge things in those instances. But that's where the blower feature could prove useful. However you'll still need to use canned air or an air compressor to really dislodge dust from certain things like cooling fins when it's been sitting on the surface a while. The sound it makes isn't bad: about 75 dB (C-weighted) at 2 feet away and the frequencies are mids to mid highs, so not piercing. Overall I'm happy with the performance and the value.

Overall, I'm satisfied with the results of using this small portable vacuum. It's power is certainly NOT as great as something like a Dustbuster or something from Dyson, but for sucking up crumbs and paper scraps and the debris that accumulates on a desktop, on a keyboard and the like it's fine. Also, I didn't know until I opened it that it will BLOW just as strongly as it sucks. The main device is a cylinder. On one end is a port for an attachment to suck up stuff. On the opposite end is a port for an attachment to blow stuff around. Not sure why I'd want that but it works well.The shape of this device seems strange to me. It is a large cylinder, roughly the size and shape of the original Amazon Echo (Alexa). For a function so simple it seems odd that the device is so large. The size isn't terrible and doesn't compromise functionality but it seems much larger than it should have to be.

vacuum came with 3 heads that works on both side of the machine. the suction power is really good, 5 minutes in my car and you wouldn't believe how much dirt it caught. I never would've thought my car was so dirty. the blower is a really smart design, making use of whats already on there. I'm using it for both the car and my work space. I'd say it was a smart buy

When I first got this vacuum I charged it up over-night. When I clicked the power button, it did not turn on. I wrote to the seller and got an easy fix, hold the on/off button for about three seconds. It worked like a charm!!! Thank you to the seller for being responsive and understanding.The vacuum has plenty of suction and blowing power to clean my computer equipment. The attachments make it very easy to give your computer equipment a thorough cleaning.Charging the unit is easy and convenient.I recommend this product for anyone looking to clean their computer.

I can't believe there are reviewers saying this has powerful air flow. It does not.I might as well whisper sweat nothings into my computer as try to use this device to blow dust out of my keyboard or to vacuum any up.In fairness, it WILL suck up some dust, but you have to be right on it and actually scrub with the brush to loosen it.I returned mine and will probably get either a dedicated blower or a plugin vaccum.
