Hello,

On Saturday I was cleaning some carpets with my prochem blazer t/m and the vacuum strength kept changing. One minute it sounded strong at the wand end, the next you could hardly hear it. I've checked for blockages in the hoses and into the waste tank but it doesn't appear to be there.

Has anyone else had this problem and worked out what to do? Any suggestions/help would be greatly appreciated.

Thanks,

Dave

is the vac relief sticking? can you hear the engine when the difference happens perhaps the engine is not running right and the revs are diminishing slowing the blower

Maybe the belts are slipping
