MOLGSDTH Car Vacuum 120W 8000Pa Mini Cordless Dry/Wet on my desk for review. First I charged the vacuum cleaner, which was easy and quick. The car is now ready for testing. I pressed the switch on top of the vacuum once for low power and then again for high power. At low power, the suction power is good. At high power, the suction power is noticeably stronger. The vacuum cleaner comes with several attachments. I just put the brush head in the machine to clean the keyboard. Low and high frequency suction is significantly reduced with the nozzle inserted, but that's enough for my keyboard. This machine is lightweight, well made and easy to use. A very limited instruction manual is included but not required. Conclusion: If a small and portable vacuum is needed, this device should satisfy many people as long as they don't use attachments that significantly reduce performance.
