Any users, I've been thinking of getting something like this for a year or so now.

You could just top the tank up with water from a stand pipe, maybe. What say you?

do you mean this?

That is a joke right? What a load of rubbish.

I reckon it's level of usefulness will depend on the type of work you have and what filtering facilities are available to you.  Certainly not rubbish though IMO.  Personally, I don't currently have a need for such an item, but I can see circumstances where it would be useful.

It is not a joke, they are sitting in our warehouse, they do exist. A processing trolley, such as above, does have a limited level of usefulness for the average window cleaner (in the US they all use them). It is not rubbish as it uses very high quality components and works very efficiently.

I personally have 'steered' quite a few clients away from these units so far, as I felt that it did not suit their needs.  For the right user though, this will answer a very specific need, in which case the RO trolleys are brilliant bits of kit.

I would think its ideal for those that need to use a system within courtyards and office blocks just hook up to a tap without having van mount hoses trailing the place.

I thought it would be ideal for most, no? If you run out, you can top up, its a fast filter anyhow. Or you can just filter tap water from the tank and top the tank up from the mains.

Or is it not so usefull?

It could be used in this way by almost anyone.  It will fill anywhere from 80-150 litres per hour in real conditions (not the near impossible 500 lph quoted by some manufacturers). It could be used to fill a static system and then transferred to a vehicle to fill a vehicle system or it could be used out on a job.  The one proviso with using it this way is it's size and weight.  It is perfectly possible to wheel it around, however it is not light enough to be picked up by one person. The cart is primarily aimed at the commercial window cleaner.

Umm could it be used by the property maintenance staff of a school or old peoples home rather than bringing in an outside cleaning company. Or am i just guessing?
A school or company could buy one complete with pole for less than £3000 to be used three or four times a year perhaps and tuck it away in the cupboard 'till next time.
Or maybe a windowcleaner who wants commercial work but not a large van to hump the water about?
