Not used it , but looks like great value for 2250 depending on how you use a portable .
3000w heater + twinvac + 500 pump
Would prefer to see a 2" vac outlet , If you dont need to use more than 50' hose then its fine , but for runs of 75' i would get them to fit a 2" outlet if possible and use 2" hose .
If you dont need a lot of pressure , you could get the same elite with basic 100psi pump for £1450 and upgrade to a 220psi aquatec pump for a couple of hundred . ( mytee use it in the speedster 250 now , replacing the 250 pumptec .
If you want to use longer hose runs than 75' i would look at some of the more powerfull extractors , like the airflex turbo or others ... but adding an inline heater will push the cost to over 3000 for any of them .
