Boring but important tiny hoover question

[TheRealMrsJamieFraser]

Without going into too many details my car desperately needs hoovered and my bog inside hoover isn't any good for this.
It's mainly for all the tiny hard to reach areas, between seats, under them etc - not so much for the carpets.
Does anyone have a wee mini super powerful tool or vacuum attachment that does this well? There was an advert on FB a few weeks back for a vacuum with silicone tentacle like things on the end which looked like it might work but I'm always a little reluctant to buy from FB!

My hubby uses our Henry hoover for the car and for the crevices he uses the cardboard from a toilet roll or kitchen towel - tape it around the pipe and then pinch other end to get down between the seats etc x

Our local handwashing carwash place does a "mini valet" for a tenner. They vac inside, sponge spot clean any marks on the seats and dust down all the surfaces. Doing that once a year would be cheaper and easier than buying the tools and doing it yourself.
