Just tried out the Gtech cleaner in the car for the first time and this really is not suitable for cars. It's too bulky so it's difficult to get it into nooks and crannies, it doesn't have suitable attachments and it doesn't pick bits up as well as it should. Like me, it makes an annoying whiney noise all the time and if you have any level of tightness in your back, you are really going to feel it.
I bought it because my OH was insistent that the household vacuum cleaner was not for use outside so what did she say when I came in complaining about the Gtech? Why not use the household one then FFS. Total waste of £179.
