Query: Did not last as long it should

I purchased this in October 2008. I used this lightly - about 2 to 3 times a year - to wash out the air cons, underwash the cars and clean the walkways of moss. Alas, today (15 Aug, 2012) I was doing one of the cars and it stopped working and gave off a burning smell. The unit itself did a good job on cleaning but in terms of longevity I am unhappy. I am giving 2 stars because power tool like this should not have such a short life. I never mistreated the unit and it was always properly stored. Having purchased additionl attachments for the unit I am now faced with if to go with this brand again or cut my losses and go with another brand.
