Why use a backpack for window cleaning?

What pump do you use to fill that fast, must be 5 gallon per minute pump?

Hey, now that’s a pro tip! I’ve been shying away from investment in WFP right now because I’m in WI and its winter. What % alcohol would you say you add?

I think I add about 1/2 a quart to my backpack maybe less. Keep in mind that the water will freeze on the ground so some ice melt will be needed if icy side walks will create a hazard.

I just pour the water out of the Jerry Can into the BP. Do that twice on a house with 30 upstairs windows. Right there on the lawn under the next window you’re gonna clean. No big deal, right?

PS
This guy on YouTube knows how to fill Jerry Cans at home fast. At home I fill’m slow because my system won’t purify the water if I fill’m fast.

This is becoming painful.

So the backpack takes 30 seconds to fill, with Jerry can, how long does it take to fill the Jerry can?

That depends on the method you use to fill them. Did you watch the video above. He’s got it dialed in.

I got it, spend 1 hour filling Jerry cans to bring to site to refill backpack as needed.

My guess is 3 minutes each can

I think I am missing the benefit carrying around 20kg of water plus lugging those 20L containers that is a gear deal of lifting vs dragging a hose that very light around the place.

Its like using a pressure washer with a 10’ hose and moving it 6 times to complete the job vs 1 long hose job done with less interruption.

Don’t you have a route with. Lot of cut-ups. I might of asked you this before , but cut-ups An WFP. Is like Lettuce & Tomatoe. I just picked up an account 2x a month with cut-ups. That biotch is getting water fed every time. I normally wouldn’t even go after a route job with lots of cut-ups, because they just won’t pay, but this just fit in price is ok, but should be more

I don’t like leaving the side walks wet. Can you imagine that? :smiley:

Wel in the winter I understand , but other than that :thinking:
