Anyone have the Tsunami HPC 6120? Can this unit be used with the 3rd party turbo nozzle? Main focus is to clean parking area algae/molds so I was wondering of this model have enough power to do it. Interest in HPC 7140 but that unit is brushless motor and worry about longevity but it does come with turbo nozzle. I probably use water jet maybe once a month just to do house cleaning. Thoughts?

HPC 7140 is more suitable with higher pressure rate

When pressure is too strong, it will break the cement plaster or the tiles grout.

I use a normal carwash pressure washer with 25degree nozzle. Strip away algae and molds just fine. I think rotating turbo nozzle too strong, will strip away your paint too.

I want rotating turbo nozzle so the job can be done faster and if can strip paint it would be nice since I have plan to paint outside wall.

Whats the cheapest for water jet, reputable brand, budget rm500 to rm1000

From what i remember, a turbo nozzle would NOT work on anything less than 3600PSI @ 240 BAR.

All the models TS states is only 100-140 BAR. (HOME USE)

So a turbo nozzle becomes a sprinkler only. 🤭

Just a nozzle will not turn every pressure washer into an industrial strength machine. No freaking way.

All the common pressure washer only supports fan or direct jet nozzle. Or aerator for detergent foam delivery.

If you really want power and the ability to use a turbo nozzle, you need to get an industrial strength pressure washer.

Else do a little research on pre treating surfaces before power washing if you want to get rid of wall & floor algae with lower power washers.

I bought one china brand from shoppee forget 120-140 like that. Strong enough to clean every dirt. But I also rarely use it.

Dunno wanna sell it back or not coz really rare use

I recently bought a HPC 7160. It can clean the parking area algae using the multi power nozzle but need do it slowly. Im puzzled why Tsunami didn't provide turbo / rotary nozzle for supposedly a better model.

I did asked Tsunami if we can use turbo nozzle from HPC 7140 But they say not compatible wor. So far i didn't explore with 3rd party nozzle yet

I thought hpc7160 would come with turbo nozzle since its more powerful unit given its price. Now its make me question if hpc7160 really as powerful as hpc7140 because that unit does come with turbo nozzle. Disappointing to hear because I lean towards getting hpc7160 for its induction motor.

But they demonstrate using turbo nozzle at 1:05 minutes in this video.



Even Bosch 110 have its own turbo nozzle as shown at 11:00.

I bought a Keelat Handheld one. For RM 90+ actually does the job just fine to pressure wash small sections of walls and floor at a time. Best part is small and easy storage. Cons is battery life, but hey, just buy a spare and swap that.

Then maybe the tech improved already? Before pandemic i wanted to get such nozzle for a basic 100 bar karcher but all of it shows very high PSI. The bosch one is 110 bar. So there is a limitation on how much pressure needed to use one. Even Karcher K2 is a 110 bar model that could support turbo nozzle. When i bought my unit, turbo nozzle only existed for industrial machines. So its an updated info for me then.

I don't think that type is strong enough to remove algae on floor.

Karcher calls it dirt blaster.



According to website its compatible with

K 2
K 2 Battery Set
K 2 Classic
K 2 Classic Home
K 2 Power Control
K 2 Power Control Home
K 2 Premium
K 2 Premium FJ
K 2 Premium FJ Home
K 2 Premium Home
K 2 Premium Power Control
K 2 Premium Power Control Home
K 2 Universal Edition
K 2 Universal Edition Home
K 2 Universal Edition OJ


But karcher assesories are too expensive. Hose too short and dirt blaster alone is around rm130.

Yeah. Thats why i was looking for compatible nozzle waayy back then.

Found this comment on their webpage



On reason why 7160 can't use turbo nozzle

previously bought one from tesco , rarely use it too , then my neighbour used to borrow to wash his car then he said sell it off to him , then i said okey since i dont use it much

It's nice to wash car with that. No need soap. Just shoottttt

Exactly, but already sold mine, but might get the portable one thru tiktok shop, battery operated
