Angle of jets in rotary surface cleaner
« on: November 22, 2010, 06:28:33 pm »
 Apparently in order to play safe when pressure washing block paving it is better to attack from an angle(had 30 degrees recommended) and avoid  blasting down straight between the gaps so less jointing material etc gets disturbed. So my question is,are there models of flat surface cleaner out there that allow you to adjust the angle of the jets,i was looking at a picture of a replacement spinner bar for a whirlaway and it looked to only have jets pointing straight down.
                     I do not have a fsc yet but want to buy the best i can get and would be running 250 bar through it at 15 litres/min ,interpump ws251.Now my concern would be block paving where the blocks dont have as much depth and therefore i could possibly disturb the underlayer of sand leading to possible subsidence of the blocks later. So ideally i would alter the angle of attack of the jets and then my concern would be them spinning too fast so i would need them to equally oppose each other to balance. An adjustment ability would seem a major benefit in my eyes then and i was hoping some experienced users might point me in the right direction. I have used a fsc on blocks previously simply without concern so i have maybe just thought myself up a problem that doesnt exist.Any advice welcomed.

hi sean   there is a angle on rotary washers   (or they would not rotate)
the angle for pin jets is different to fan jets   ask a good supplier
i personaly keep spare spinners with various jets
the spinner arms ware out      aviod swan neck arms they ware out very fast

to be honest I've never had any problems using one on blocks.i have got a fsc from jetwash although it be the cheaper version, the angle of the jets can be changed by turning the rotary arm a bit and yes obviously if the jets are poining directly down then there will be no rotation.

another thing is you are worried about it spinning to fast,if the angle is too great then it simply wont clean  so the ideal angle for cleaning is also the angle at which will give most rotational speed. ( I think  ???)

Also make sure the fans are positioned correctly otherwise you'll end up ''ringing''.

30 degrees sound about right and make sure their both not pointing in the same direction.

Cheers for the replies,these fsc`s are not as simple as they look. I know that often people sell them and say they are a waste of time as they have to go over everything with a turbo nozzle anyway. In my opinion and experience though, i think they are an excellent tool to have even if just to try and keep the muck spray contained. I had supposedly bought a 21 inch mosmatic but on my way to the bank to send the money to northern ireland this morning the guy sent me a text to say his dad sold it yesterday,thats after agreeing the deal(was 2nd hand),exchanging e-mails,texts, phone conversations,him having it bubble wrapped ready for posting(i was paying the p+p),sending me his bank details and all agreed for bank opening,it was on gumtree at £190,thought i had finally managed to get a bargain as the description was good. So if anyone on here gazumped me i hope the head bearings are Kaput,its come with the wrong jets for your machine and overheats your pump,the hose bursts and at least 2 castors shear off completely on first use. In my head i know i should buy new then i know the history,does anyone recommend a particular type for reliability etc. I can`t remember the make of the last one i used but it was £800 ish(was told) hadn`t done much work,leaked  at the rotor bit and the gun was permanantly jammed on.
  I think maybe my basic question to the pro users is would i be better off in general paying more for a mosmatic than a whirlaway and getting 21 inch approx rather than 18 inch and does anyone recommend the techclean models and again if so is the bigger one in general a more sensible choice? Finally,whilst i am on i might as well keep going,15, 25 degree jets or 40. I would want mine to do what its supposed to do and do it well with hardly any going over again with a turbo nozzle required(i do know that can be dependent on whats needing cleaning). I have it scorched in my head not to skimp on tools but finances say look out for a hardly used bargain and then experience says its difficult to trust any seller these days and i come back round to having to buy new and then i would rather pay £700 for the right machine than £500 for a compromise which i later want to sell off because i have bought the one i should have bought in the first place.

Yeh, everyone assumes they'll rip anything out, tough weeds the lot. There's a reason why they're called surface cleaners.
Even buying a new Whirlaway the black wheels fall off within hours. The grey wheels made by Blickle are the best.

Is there a good seller of this kit out there,i mean one you ring up and say,yes,whirlaway please without the crap wheels,please fit the better type and see me right on a spare spindle?,or who might just say,well if you pay this much(?),you get this machine and the wheels wont fall off and you wont need a spindle until its done a years work,comes guaranteed and if the gun keeps jamming it will be replaced free of charge?.
          One thing becoming obvious i think is beware 2nd hand.

Chris at Centurywise can help you.

http://centurywise.co.uk/category.asp?cid=39

He'll throw in some Blickle wheels with a FSC.

I've also bought direct from the US and can be a saving but some won't ship over here.
