Just go for one of the same physical size (assuming that you were happy with the suck that the old one had) and an antistatic (black) nozzle. They're all pretty much of a muchness unless you start paying silly money for a 'precision machined' one from Japan (there's a thread/post about one somewhere on here*).
P.S. If the existing one isn't sucking then it's probably the foam piston seal that has failed or is gummed up with solder fragments, a good clean sometimes helps, you can probably get replacement seals but it probably isn't worth the hassle unless you're feeling very poor.
Thanks Gyro. I managed to take apart the other spare solder-sucker.(I couldn't earlier so I thought it was sealed). Gave it a good cleanout and lubed the o-rings. Seems to suck better now, though I'll still look at getting a better sucker while I'm at it.
The suck of my old one that just broke seems to do the job, though I have nothing to compare it with so it may be low quality suck compared to what's out there today. I saw the one from your link on Amazon (Engineer-SS-02-Solder-Sucker). How is this one? From reading the link you provided, it seems the user got the issue sorted and was able to replace the o-ring?

I'm using an old powerful modified vaccum cleaner with a pedal switch and a small PTFE tube, never full, never colmated, powerful enough to remove all the solder of a circuit pad in order to make a through-hole component falling down by its gravity of a cold mulilayer PCB, can eat a lot of solder in a millisecond, can cool down some sensible zones of the PCB during the heating process,... constantly at full power
Oh nice, smart thinking. Wouldn't the noise get annoying though, constantly starting/stopping the cleaner? Clever idea non-the-less.
If you want to buy a quality manual solder sucker once in your lifetime, and never have to replace it, the (genuine!) Edsyn Universal SOLDAPULLT US140 is a great choice.
Easy one-handed operation, and all replacement parts are inexpensive and readily available.

Definitely the SOLDAPULLT. Costs more now but you never need to buy another one.

Nice, thanks for the suggesting SOLDAPULLT

. I can't get it from edsyn due to them being in USA (Im in AUS), so postage is a killer. I noticed 'Amazon AU' have an identical US140 sucker but called 'Hozan US-140'. seems like Hozan is a Japanese company, so would this one still be OK?

Hopefully you can buy from them & they're not just a warehouse (Ill give them a call).
I had a look at the specs for the
'The Original Deluxe SOLDAPULLT (DS017)' and the
'Static-Safe Deluxe SOLDAPULLT (DS017LS)' based on 'Arts' comment, and I have to say I was quite surprised! 13"/330mm long. That's rather large, isn't it? Why would it be so big? I think I might have to pass on those two lol, seems too big for me tbh.
The SS350 and SS750LS seem to be a better size for me. I'm not sure of the exact differences other than the SS350 having a metal body and being 13mm longer than the SS750LS. There doesn't seem to be much information on them.
Any opinions on the
'Engineer Solder Suction Device SS-02'? It does appear to be somewhat 'fat' compared to the slimmer suckers from Soldapullt. Does the extra width cause any issues getting down to the pads? Amazon AU have them for $28 ( a little more expensive than the 'Soldapullt' SS350 & SS750LS).
Edsyn Universal SOLDAPULLT US140 is a great choice.

I have a rebranded version of this on the recommendation of a grey-bread, their recommendation "get one with as high a pumped volume as possible"
What rebrand do you have? There's one on Amazon 'Hozan US-140' (linked above in post), is that the same ?
Thanks again guys

. So far on the list I have,
Hozan US-140 - Amazon $28
Soldapullt SS350 - Mektronics $26
Soldapullt SS750LS - Mektronics $18
Engineer Solder Suction Device SS-02 - Amazon $28
Also unsure if the SS350 with a metal body is worth +$8 over the SS750LS with plastic body. Thoughts?
Thanks again
