Rx20 nexgen I HATE ENGINEERS!!!

[Dwain Ray]

Ive run rx20's for about 30 years now i still have one of the first made in my storage shed. Last year i bought a new nexgen, i bought it for the handle. Not because my old one didn't work. Over the decades there has been many changes made to the rotary. Till now most were good.as i said in the beginning i bought the new one for the handle. In the past the locking mechanism has been a tension based system and soonest or later it slips on the last generation hydramaster came up with a fix to the problem by putting brass plugs in the side so as to be able to tighen the tension. They sold the plugs as a kit to retro fit older models. The new handle on the nextgen fixed that with a positive locking system love love it and the engineers should have stopped there. But NOOOO if they did they would be outa a job so in there infinite wisdom they went on. First they made a useless wand to vacuum corners . But inorder to do that they firts reduced the vacuum hose size from2" off the star totjis magnificent wand then further reduce vacuum to 1.25 " thru the breakable plastic tube then back to 2" out wtf!!!. No wonder they went to 3 jets and re designed the heads to have smaller vacuum slots . That was the first thing to go on mine!! And i used off the shelf hydramaster parts to fix the problem. I went to my storage shed and robbed a bolt on vacuum tube off an old low speed rotary and bolted it on the new one works great 2" all the way hydramaster if you're reading this my suggestion is to offer it as maybe an option YOU CAN CALL IT MAX VAC PACK I know some of the kids today want the toy wand but for those of us that want the power at least make the parts available

I didn't stop there. The engineers really screwed with this rotary. So im going to show modifications 1 at a time. Next the new button!!! I would like to meet whoever came up with this, i thing the need to drug test at hydramaster i have a bill for a hole in a wall I'd like to give um!! Allow me to explain, the engineers with all there education came up with a second button on the handle which allows you to operate the rotary solutions & motor with 1 hand , great idea in theory, but the way they accomplished it was to parallel the motor handle switch so now if you lean over the handle such as i did to pickup a paperclip and your fat belly comes in contact with the 2 buttons the damn thing takes off!!! They've bypassed the safty button feature thats gone on mine now

Third problem was were the hose attached. Before it was hard plumbed straight out and sometimes got in the way so they went to a short jumper hose. Great idea on paper but in the real world and using a high temp machine youll end up sooner or later with blisters on your thigh from the quick connect. I did like this idea and came up with a novel fix, first back to the boneyard for old style Y strainer and back plate. After converting theto old style connect i fabed up a adaptor from a m & f quick connect and a m×m 45° brass fitting that i put on after it appears i dont have a picture of that at this time ill post it later

Finally, the star. I opted outa the 3 over priced cone jet masterpiece with the smaller slotted vacuum heads they came up with. Instead I ordered mine with old school 5vee jet and standard vacuum heads. Then i modified it to accommodate prochen vee jet filter screen ball checks. The way they plumbed it there was no room for them. I used 1/4× 1/8 reducing 90° elbows with a 1/4×1/8 bushing to get the space and it is the exact same size as what the had without ball checks and filter screens and thats how i made the mighty rotary great again sorry for being so long winded and having to break it down into sections but this is why I HATE ENGINEERS!!!
