John:
Is this is the latest version? ?How are you finding the filter cleaning to be? ?Possible clogged filters and subsequent (unpleasant) cleaning of these filters seems to be have been one of the main issues. ?I'm currently considering getting an RL-160 and trying to get opinions on the latest model. ?There's now even an option for attaching a compressor for pneumatic cleaning of the filters (very expensive option though).
