Dust buster type devices

[Rob_125]

Hi all, just wondering if anyone can recommend a dust buster type Hoover. Had a look around, and there seems to be loads ranging from £10 to well over £100.

Main requirement would be:

12v charging (possibly 240v too - although I can probably sort a charger)
Not massive
Reasonable suction - mud/sand ect
Around £50, but budget can be flexible if it really is worth it.

What do people recommend?

We have a Beldray cordless in our MH. Its really good - so much so that we bought one for the house as well.

I'm not sure if it can be charged off 12v though but maybe worth a look.

We brought a Dyson Car+Boat a couple of years ago. Its a standard handheld dyson, but came iwth a 12v charger. So I presume you can buy a 12v charger that'd work with any other handheld dyson.
