Hello Paul
I used the Wonder Wand in conjunction with the CFR500 I had - great combination.
When I bought the Scorpion 2nd hand off Spencer Davies I tried the W/W with it but, and I dont know why, it didnt feel the same effect was gained.
With the Scorpion and my TM I now use a 12" 2 jet wand that came with the Scorpion from Solutions, and sometimes a 12" 4 jet wand I got from Ashbys. I have a Greenglide on the 2 jet. Both are 1.5" tube. Both the Scorpion and TM is on 2" hoses.
Difference between the TM and the Scorpion?
Time mainly.
That is the set up and shut down time. I have used the Scorpion quite a lot this last few weeks due to nature of the jobs, and was reminded of all the bucketing of clean water and then the dirty water, plus getting the extension cables set up for electrics (3 cables - 2 for the machine, 1 for the external heater).
Did a job yesterday with the TM. Took me 2 hours from getting there to driving away. Done it with the Scorpion in Jan and it was 3 hours (ish).
As brilliant as the Scorpion is as a c/c machine, I have to say the TM is better, and mine is "only" a 18hp machine (sort of bottom of the range

).
I am just glad that my "backup" machine (the Scorpion) is such a good machine. If it was anything less of a machine then the times you have to use it would really make life really difficult by comparison.
The one thing I dislike about the TM machines is when you get back to base (home) you have to dispose of a load of dirty water down the sewer drain (Prowler is the exception).
So you come home and just all you want to do is have a shower/bath, and it may be raining or windy, and you have to do a bit more - its only 10 minutes but thats the part I dont like. And also cleaning out the waste basket - collects all the rubbish from the carpet into the waste tank. Thats a stinky job.
