Cleaning dust with a small vacuum S

[Quai34]

Hi,
I know that, when I saw inside of my D50 when my technician opened it, they were a lot of dust indice. I have now a cover for each keyboard that I own.
But lately, as I need to look for a job, I couldn’t deal with music, band, shows, while being stressed by my job research, so, I put the band in stand by.
I should use the cover but I like to play for me a little bit now and then and removing all the covers is a bit of a burden and it’s way nicer the way it is displayed without the cover. If I have some bad days with bad mood, I go downstairs visiting and having a look at all the Instruments and they heel quite well my mental situation; like gear could be a good medication.
So, I was wondering if there is a portable dust vacuum that is available on the market like the one you see on television for dust in your car on the seats. Like one that is powerfully enough to take off the dust from the little interstice between keys but not enough to damage the electronic or dampening pads or little plastique “reeds” that might be under the keys, etc.

Let me know if you have done that in the past.

Sincerely
