There was a problem filtering reviews right now. Please try again later.
P.S. What convinced me to ignore the bad reviews was the user manual. It is freely available online (check Robinair's website) and it directly outlined how to avoid all the issues the negative reviews were mentioning. Following the manual personally avoided every issue, which is why I am convinced those negative users did not read it before use. I do recommend buying the EPDM hose, even in a well ventilated area. 3 feet of it cost me < $5 at the local auto parts shop.
Reviewed in the United States on August 6, 2022
Biggest complaint I have is the exhaust port. I bought a vacuum exhaust muffler to contain any oil mist coming out. But the exhaust port isn't threaded. It's basically just a circular pipe sticking out. I ended up using hose and a hose clamp to run a hose to wear I could mount the muffler, but honestly it doesn't look very good. Pretty sure I've seen other pumps with the muffler threaded straight to the exhaust port.
All-in-all I would recommend this pump for the price. Build quality seems good and I am hopeful it will last me a while.
I did lose a leg shock absorber when pump fell 4 feet from a shelf on the truck. Pump still work fine.
Someone complained about pump not starting when turned on. This is a common problem with vacuum pumps, especially when pump oil is cold and happens to me every winter. It is not pumps fault but basic physics. Crack seal where hose connects to pump so pump does not have to start against low pressure and thick oil. Once spinning reseal and pump will work fine. If pump REALLY cold, it is probably not going to start at all. You can heat pump with a propane/Mapp gas torch to heat/thin oil. If this concerns you at all, do not do it.
Some have complained about misting. It moves 8 CFM a minute in the beginning. OF COURSE you are going to get mist on any significant system! If you do not want mist, restrict flow until you ger a fair vacuum, but time is money for people who buy an 8 CFM two stage pump. Mist is the tradeoff for pulling a fast vacuum.
One last point to make. It is very conmon to not get deep vacuum. Happens all the time. It usually means your system or gauge setup has a leak. It can also be caused by an uncalibrated vacuum gauge, your pump oil being dirty, or you have an improper oil level. All 4 of my pumps still pull a VERY deep vacuum when deadheaded and checked against an accurate gauge.

Muy recomendables.
- So far this vacuum pump has worked flawlessly for me with no issues at all.
- It's reasonably quiet compared to other cheaper lower CFM vacuum pumps I have used in the past.
- It does its job quickly and smoothly as it should since it is an 8-CFM two stage pump.
- The oil level indicator window is easy to see and judge proper oil level and cleanliness.
- The oil drain valve is located in a good position for quick and easy draining as advertised.
- It's a sturdy product that is clearly built to last.
- At this point it gives me piece of mind knowing it's a quality product and it's ready to go for me anytime I pull it out for use.
Not much else I can say about this pump except in my opinion it's a good investment if you are looking for a worry free quality vacuum pump that should keep working for you for years to come as long as you take care of it and change the oil when needed.
I hope you found my review helpful.
