My zipper with total 30 inch vac slot works just fine with my Mytee- M5 portable and even better with my Mytee ETM.
The reason may be is that the Mytee M5 vacs are plumbed in parallel.
The ETM's 4 vac looks like its plumbed in both parallel and series.
They are also set up with 2 or 2.5 inch vac hose...
I've had portables with Vacs plumbed in series and with 1.5 inch hoses and they were a disappointment. These types of portable should only be used with maximum of 25 ft of vac hose and 12 inch wands and only 1.5 inch hose and tools.
