I went to asda basildon and got this amazing combi vac (vacuum and blower) for a tenner. It also includes 2yrs warranty! Manual is here: http://www.earlex.co.uk/pdfs/wd1000.pdf. Looks as if you buy attachement can be used as spray painter too.
Also they had the Earlex steam wallpaper stipper for £10 too. Manual here:
