Hi, I’m Scott from Alpha Power Cleaners and today we’re going to be troubleshooting no suction on a Tenant M20 floor scrubber dryer. So before starting any vacuum diagnostics, I would recommend that the tank recovery tank is cleaned and flushed through so we know that is all okay. And then we would start firstly lifting the lid and checking the vacuum filter. It’s clear and free of debris.
Then we would look make sure you can hear the vacuum motor running. Then with the vacuum turned on on the machine display, you can check that they’ve got suction on the filter itself. And then while the lid is up, you can check and just make sure the seal around the tank lid is intact. No big chunks missing. With the vacuum motor running, seal’s good. Back filter is good. So, we can then drop the lid, remove the hose, then check we’ve got suction at the end of this hose just by putting your hand over.
