I had the opportunity to "play" with a Speedster at a suppliers Open Day a few years ago. I must say I was very impressed with the performance and it seemed to work well with the AW29 wand supplied with it at the time. From this short experience, the only thing I was wary of was the very small aperture for filling the tank. Easy to spill water.
Since then, I have spoken to quite a few people who were displeased with their Speedsters, or new someone who was. The problems I've heard of are from overspilt water affecting electrics and premature component failure, particularly non-Lamb vacs and heaters, along with support from their suppliers. I know of one distributor who, so the story goes, stopped selling them for this reason.
It's up to yourself to decide what to buy, but I must say that your experience today may be an indicator.
Safe and happy cleaning
