the deisgn of the freedom trolley isnt that bad really
afterall its a sack truck with a metal box holding the battery and pump
its the same design in theory as LOADS of DIY'er system
sure the DIY'er saved 000's of pounds aswell
I think you mean
1000's of pounds
! Since 000 pounds is very little; nothing in fact!
Anyway, most entry level WFP users will begin with a trolley or a backpack system; then upgrade to a van-mounted system when and if they see the requirement and associated benifits.
Two local guys to me both began by using trolley systems and eventually up-graded to a van-mounted system.
One of them started with a Freedom Trolley, but found it too cumbersome; so sold it on this site for half of what he paid for it within a few months of getting it.
Next he bought a backpack and found that better, but tired of re-filling it (he does 100% WFP; as opposed to 'tops only'). Then he bought a van and a van- mounted system and also made his own 90 litre trolley system. (Subsequent to this, I've still seen him using the backpack; for those difficult to get areas).
He's a bright bloke, an ex engineer of some description, and he told me that Andrew's Freedom Trolley was too heavy for the little water it carries. He also prefers the backpack to the Freedom.
Another user has told me he lost weight using the Freedom Trolley (can't be a bad thing though; can it; I could do with losing a bit) because it can be so physically demanding, lugging it about.
What I think is wrong is that trolley systems are aimed at the entry level WFP user and Mr McCann uses this site to advertise his product to the window cleaners who want to take the first step towards changing over to WFP. They maybe experienced in 'trad', but inexperienced with the world of WFP.
I don't think the product is that suitable for most entry level window cleaners, since most trad users work from a car, and still will carry ladders; you can't get the system out of your boot without a fight when you've ladders on top. Unlike the backpack which can fit in one of your rear seat footwells.
The Freedom is also heavy and cumbersome and the name is a misnomer. Try getting it up an alleyway with umpteen dustbins in your way. You can't unless you're got arms like 'Garth'. But you can with a backpack weighing half the weight and carrying just seven litres of water less.
Steps anywhere are a problem too. Just six or seven steps really slows you down. With a backpack you just walk down them and when you get to your window, take the backpack off your shoulder and start work. It's easier and quicker, and as Andrew says; mobility = profitability.
Anyway, the 'same' system specification could be put together for a fraction of what he's charging; therefore I think he's using the naivity of fellow window cleaners to make a profit and citing, 'but I only want window cleaners to be safe' as a justification.
But that's only my opinion; but I could be, and often am; wrong; according to Wor Lass.
