Workzone Ash Vacuum Cleaner

Practically new as it was used once, not a fan of it as I prefer just manually clean my fireplace, put it in shed, I tried it again today hoping to sell it and clear a bit of what things I'm not using. It sucked the ashes right and a few bits of cinders, but for whatever reason it suddenly stopped, I opened and for whatever reason I am not going to do the reverse way to clean the filter so I put it back. To any possible buyer, if you have the patience to check the filter and clean it yourself, I'm willing to let it go at the price that was last agreed as per the thread below, otherwise if someone nearby is willing to fix it for me, I will be selling it at the asking price in the ad stated or go down a bit. Thanks
