Kevin,
I don't honestly believe I can pass comment as I use a home grown set up which is the way it is to overcome the original set up's short fall. The original vacuum started to fall to bits and then blew a vacuum so I dusted the skip vac off and found it better than the original although 3000w opposed to alledged 4200w. It waste drum drops off the bottom onto casters to m/t and has s screen and fluid valve below. Its heavy and its too big to fit through a door which means its restricted when it comes to terraced houses with no rear access. A pump out would be nice when its raining and for other work but we just stop and drain the tub.
I find a 50mm vac inlet no real problem but suck a bucket of water regularly to clean the whole system.
I have tapered carbon fishing tubes which are a pleasure after the telescopic alloy versions.
The power pole is heavy but gets good use as I have various attachments for the 10mm QR - hooks, spike, disc and nozzles to P/W.
You would have to test side by side to really know whats best but some would still moan and we all know who they would be
