My SIL has just given us their bissell spotpro carpet cleaner. Apparently they have only used it once, around 4 months ago, and didn't ever empty the water out until last week when they decided to offer it to us.
As far as I can tell it doesn't smell and there doesn't look to be mold or mildew in it, but I'm unsure about using something that might make my carpet dirtier rather than cleaner (given our carpet isn't especially dirty to start with - I'd just mentioned that we have a newborn and it would be useful to have something to clean any spills!).
Does anyone have one of these - are they any good? And would you just use it again without deep cleaning it / if not then how do I clean it out suitably to ensure it's good to use?
