Worst customer service I have ever delt with. On the phone for 35 min. and got cut off! On phone again talking and explaining my issue and they cut me off again after 30 more minutes!! Sams obviously has call center in India or somewhere. Horrible!! I won't be renewing my membership!!!!

Received on Feb11,2025. Was a little disappointed it came with no pallet because it traveled a long way. Upon opening the box they use sheets of wood to protect the top and bottom of the unit. The unit feels well built and came with a lot of accessories and features. It is big and heavy but is manageable with the handles. Everything is labeled on where everything is. Checked and double checked the unit thoroughly. Read the manual twice, added oil and it started on second attempt on Natural Gas, and will only be used to run on NG. This thing is really quiet and only have 15min runtime so I can not say on the longevity but hope it lasts for years with proper care and maintenance.

Recently purchased this after the Helena storm with a smaller generator just didn’t cut it. Looking forward to putting this beast to work or maybe not..don’t really want to lose power. I purchased this after a lot of research to insure I got the right one. Went with inverter as the standard generator is loud. This one has the 50 amp plug as I had added a plug and tied it to the breaker box with an interlock. Also having to find gas was a pain, so I am looking forward to getting the natural gas set up. One thing I did notice was that even though this unit comes with a 1/2 natural gas hose it has a 3/8 inlet connection on the generator for the 1/2 inch hose. I purchased a 3/4 hose and adapter for the 3/8 connection as I wanted to ensure flow was not a issue, maybe over kill.

I only have 5 hours on it for the break-in so far. It doesn't come with the ATS cable, but I am not going to use that anyway. The air filter is really wedged in there, not the easiest to open and remove to get it oiled. Plus, the plate behind the air filter to the carb intake fell out and was a little difficult to get back in properly. The oil strainer is also a little difficult to reach. Other than that, it performed well on my break-in runs up to 4kw.

I have yet to use this generator in anger but I have run it once a month for 1/2 hour to test my whole house backup system for the last several months. I run 240 volts from the 50 amp plug to a 50 amp whole house interlock. When I got it, I ran it from a 100# propane can and it ran well on that. I have just installed a 3/4" NG QD on the side of my house (which a certified plumber hooked up and tested) and ran the generator this month on NG. I plan to use the propane can as a backup fuel source going forward. I have not tested the generator with gasoline yet. It starts right up from the propane but takes a bit to start from the NG line as I suspect it needs to purge more air from that line as it is larger (3/4" with 1/2" adapter) and longer (20 ft.). I was able to run my home's 3 ton AC unit (with soft start) this summer with this generator. About the highest steady load I have seen on it with NG so far is 5700 Watts. I had low idle On and the lights momentarily dimmed when my 4000 Watt water heater kicked on but the generator responded quickly and automatically bumped up the RPM to meet the demand.

Purchased the Genmax 11000 about 8 weeks ago. The Genmax arrived via a delivery truck and everything was in perfect condition. The generator was well boxed to ensure the product was not damaged. I was surprised how well made the Genmax is and think it will provided years of great service. We purchased this product as the emergency back up generator for our whole house. This handled our 5 ton air condition with no problems. We did have a soft start and interlock system professionally installed by the electrician. We live in the Houston area. Natural gas will be our preferred fuel source. Would like to see a custom Genmax dust cover included.

Wow! Genmax Nailed on this one – The tri fuel option is a must these days and I will never get a generator without out it. I did some shopping around and this was the only big wattage unit that came in an enclosed inverter while providing me with the running wattage that I needed to power my house. Ordered this unit back in June and the unit arrived at my house less than 3 days later- and the white glove service was impeccable. The guys unloaded the unit for me and dropped it off exactly where I needed it to go which was sweet, I was a little worried about maneuvering this beast but once it arrived the heavy duty handle bars and wheel system make it super easy to move around, youre carrying less than a quarter of the weight. I was looking at the Westinghouse unit which was a few hundred dollars more but was an open unit. The fact that I can keep this unit running outside indefinitely while having it connected to my natural gas line and have people over in my backyard without being disturbed was shocking to me.. the noise level is so low you barely notice it in the background. I also have been in talks with their support team about getting this unit connected with a transfer switch which I will be doing soon – Oscar and the genmax support team were awesome with answering all of my questions and getting back to me with emails – very happy with my purchase after 2 months of owning

This is great bang for buck buy, I don’t see anything else on the market that gives you more for your dollar than this pressure washer. I’ve had it for about 3 months now, broke the nozzle after a little bit , got a hold of the aupprt and they sent me all 5 nozzles again. No complaints

In all honesty I was afraid to buy a gas pressure washer- I wanted electric just for some home diy projects like my garage floor. The price on this was unbeatable and so I bit the bullet and bought it. This works perfect and it’s super easy to set up and maneuver. I can’t say I’ll ever go back to a electric pressure washer as I really feel this unit will last the rest of my life time. It’s strong and I called their support cuz I broke my wand and it cracked. I had a replacement at my door step 4 days later. Great company, better product. Kudos to genmax

Only run for one hour break in so far but seems nice and is quiet. Only issue so far is when researching this before buying, the manual stated it was a floating neutral generator with an included bonding plug which is what I wanted for connection to my house as backup power. However, when it arrived it is a bonded neutral and there is no information on the Genmax FAQ page that the manual points you to on where the neutral to ground bond is that you need to remove. Genmax service also still thinks this model is neutral floating by default and I had to send them a picture of my front panel to show them that it said Neutral Bonded. They did not have any updated instructions for this model either.
