Since 1969 I have owned and also repaired and refurbished every model juicer from model 230 and up. I have taken apart all models down to every last nut and bolt including the motor and the hydraulic system-- including a new 275 model that was destroyed in a UPS shipment. I am therefore very familiar with the evolution of the improvements in the Norwalk juicer.

I am a psychologist and business person who owns and operates a residential holistic housing opportunity in southern California where people can develop good health habits and learn how to use the Norwalk juicer. I began my professionlal career as a physical and health education teacher in 1960 and later taught special education. I next came to California to earn my Ph.D. degree and later taught counseling, management psychology and organizational development at the university and graduate school level. At this point I began to focus on the Whole Being and founded Whole Health Foundation. Since the health of the whole being begins with the physical body the Norwalk juicer is an ideal tool to help people maximize their physical health. Without physical health the mental and spiritual health can not thrive. The Norwalk juicer is best used for prevention of poor health but is also ideal as a therapeutic aid. When cancer is caught in the early stages pulp free whole juices can do wonders.

I am not an authorized employee or representative of Norwalk Sales and Service so I have no reason to promote their juicer. Over the years I have traded up from my first 235 model to a 265 and 270 model and I now use the 275 Norwalk juicer every week. If you own an earlier model I advise you to do whatever you can to buy a newer 265, 270, 275 or the new 280 model. Take the big long look and think about it-- Due to the Norwalk juicer making more than 50% more juice than any other juicer the Norwalk juicer will pay for itself in a few short years from the savings in produce costs. ** Norwalk produces more than 300% juice from parsley, 134% more from celery and more than 40% from carrots. These are scientific facts verified by a reputable chemist Leroy J. Bailey. The increased juice yield is a scientifically proven fact as shown in the Bailey report.

The concentration of nutrient and mineral content in extracted juice rises as more juice is extracted. The last ten percent of juice comes out with a far higher content than the first ten percent. Also, efficient pulp making and pressing results in a higher percentage of nutrients being extracted, even if the quantity of juice extracted remains the same.

The new 280 model (released in September 2012): As I view the 280 model the jury is still out in my opinion. I think the new sloped juice tray is a good improvement on the surface of things but in my opinion the original juice tray is quite satisfactory. As for the O ring on the round escutcheon plate on which the feed tube housing fits I see this as an unnecessary part that will be difficult to clean and can become unsanitary and it will eventually wear out and not function as it is designed to do. I see this O ring as an idea that has "curb appeal" as they say in real estate but in fact is a bad idea. If I were buying a juicer for the first time I would opt for the 275 model or one of my hybrid 265 and 270 models that have the backplate corners rounded. These rounded corners are easier to clean as on the 275 and 280 models. The O ring on the 280 model escutcheon makes the 280 an undesirable model because juice can get behind the O ring. The O ring is difficult to remove and clean and even if you were able to remove it this is just one more unnecessary cleaning task. I predict that the Norwalk factory will one day remove this "so called escutcheon O ring improvement." The larger cutter in my opinion is insignificant as far as the ability of the juicer to shred produce.

I see the
O ring on the round escutcheon plate on which the feed tube housing fits as an unnecessary part that will be difficult to clean and can become unsanitary. This O ring will collect juice between it and the groove in which it sits plus it will eventually wear out and not function as it is designed to do. In addition, because of the groves on either side of the cutter opening of the feed tube housing there will never be a complete seal and some juice will still leak past at these places.

I see this O ring as an idea that has "face validity" but does not do the job. It has "curb appeal" as they say in real estate but in fact it is a bad idea.
If I were buying a juicer for the first time I would opt for the 275 model or one of my hybrid 265 and 270 models that have the backplate corners rounded. These rounded corners are easier to clean on my hybrid improved models or on the 275 and 280 models. This video shows how we round the corners http://youtu.be/jjQwS3zpYqw
.  The O ring on the 280 model escutcheon makes the 280 an undesirable model as I see it because juice can get behind the O ring creating a sanitary problem. The O ring is difficult to remove and clean and even if you were able to remove it this is just one more unnecessary cleaning task. I predict that the Norwalk factory will one day remove this "so called escutcheon O ring improvement." To date some people have complained about this O ring idea. It is difficult to clean and not a good idea.

The larger cutter in my opinion is insignificant as far as the ability of the juicer to shred produce any better than the 265 or the 270-275 cutters. All cutters do a similar job shredding produce including the 265 and lower model cutters that physics says is better. Even a 235 model cutter is very satisfactory.

The larger guide pin at the back of the juicer press plate is made of aluminum. It is a good idea providing more stability. Time will tell if the larger guide pin is better.

Based on my experience I can say without a doubt that newer models especially the 265 up to 275 are superb in design and function. Except for the 280 limitations I mention above the 280 model is also better than any model below the 265. Even the models before the 265 can be a good choice if they are refurbished and receive proper care with occasional maintenance and better still with the improvements I offer. Remember this appliance is only a machine and will have wear and tear that needs attention from time to time.

Even better than the newer production model Norwalk juicers are my improved and refurbished models sold at Whole Health Foundation. The improved Norwalk juicer models sold at Whole Health Foundation are the best Norwalk juicers available because the improvements help maximize the nutrients you want to extract. Not even a new Norwalk juicer even comes close to my improved models.

For more information call me at 760-753-0321 and I will explain in detail how my improvements maximize your nutrients and why not having these improvements can destroy your nutrients and basically waste your time making juice. Without these improvements heat will destroy you living enzymes. Why go through the bother of making juice and allow heat build up to destroy nutrients?

Most people get frustrated with the two stage Norwalk juicer process and give up after a burst of enthusiasm. My instruction videos explain in detail how to make larger quantities once or twice a week thus creating convenience. By creating convenience you make the juicing process less of a chore and more of a pleasure.

In addition to adding important exclusive improvements I have a machine shop round all the angular corners on the feed tube backplate. This makes the juicer look identical to the 275 and 280 models. I even add my exclusive improvements to the older models adding by the digital thermometer to all models I refurbish. For an additional modest machine shop charge I can also lengthen the top of a 235 or older model feed tube so that it will be impossible to reach down from the top and accidentally chop your fingers. This shorter top portion of an older model feed tube is a serious limitation-- but it can be corrected with a little machine shop work.

All models 240 and up that have the slide out grid holder and are good models if they are well maintained with an occasional minor tune up by someone you trust or by yourself if you are handy at mechanical maintenance. The elegant design of the rounded corners on the 275 and 280 models (and my improved models) make it a visual delight and impossible to accidentally catch your hand or clothing on a corner. Also it is easier to clean around a round corner. However, the 265 and 270 models are mechanically identical and a great value if rebuilt with new parts. I add improvements to all models INCLUDING having a machine shop round all corners so my refurbished models look exactly like the new 275 and 280 models.

Some improvements along the way are subtle but important. Lengthening the top and bottom of the feed tube for example makes it impossible to accidentally stuff your fingers toward the spinning cutter if you push in greens with your fingers or reach up from the bottom when the grid is out. In addition, the quality of all stainless steel parts has been upgraded to harder and more durable stainless steel. The new black pusher is a tiny bit shorter minimizing blowback and easier to keep clean. The wooden pusher is lighter and some people prefer wood for that reason but wooden pushers need to be cleaned and oiled every few months. (Use mineral oil-- never use vegetable oil.) 

The convenience of the slide out grid holder is obvious. The quality new motors are much more quiet and durable and they can be adjusted for 110/115 volt or 220/230 volt. The new motors are made to run hot so you need not worry about using the juicer for extended periods of time. The improved newer modern motors also have sealed bearings and the front motor bearing has better protection from any juice that may travel back if the front motor shaft seal begins to wear out. The improved hydraulic system also makes the juicer more effective. Model 270 and up uses the red transmission fluid while models 265 and below uses hydraulic jack oil or 20 weight non detergent motor oil. All hydraulic fluids used in older models or the transmission fluid used in new 270 models are satisfactory. 

The 250, 235 and earlier models have top and bottom plates that are thin and hydraulic posts made from 1/2 inch stock rather than 5/8. The larger hydraulic posts on the 260 and later models make the juicer almost indestructible. Also the top and bottom plates are thicker and better designed than the early models giving the hydraulic post threads more depth thus helping the juicer press to accept more pressure. (In rare cases I have seen the early model posts strip their threads and pop out. This can be fixed by drilling into the center of the stripped post and tapping in a bolt thread to hold the post with a bolt and washer from the outside, but the thick plates of the new models eliminate the need for this rare fix.) The helical cutter tends to throw pulp away from the motor and down the feed tube. The magnetic reed switch requires that the feed tube be assembled making an accident with the spinning motor shaft impossible. If the reed switch ever fails it is easy to replace. Sometimes, but rarely, the reed switch will allow the juicer to be turned on with the feed tube off. This is not a  problem and some people like that because it allows one to carefully clean the back of the spinning motor shaft.

My advice is to avoid the obsolete 230 or 235 model unless you are handy or can find someone you trust who can rebuild it. These models MUST have the motor bearings replaced with new sealed bearings for best results and longer life. Also these older models need a more modern front motor shaft seal. Even so the inconvenience of needing to unscrew the grids and the lack of modern safety features make these models less desirable. In addition some 235 models have a "safety" nub that requires one to remove the feed tube to unscrew the grid section for cleaning. This is another inconvenience of the 235 model, but some people like this feature. The 250 and 260 models have a 1/3 Horse Power motor compared to all the other models that have the more powerful 1/2 HP motor making the 250 and 260 model only good for light weight juicing. If you do a lot of juicing avoid the 250 and 260 model and get the 265 or 270 and 275 models, but avoid the new 280 model if you can. I bought a used 280 model just to make these tests and as much as I wanted the 280 to be the latest and greatest Norwalk ever, I just cannot give it that ringing endorsement. See my 280 review at this link.

If you are serious about your health you will never regret your decision to own a Norwalk Juicer. The later model Norwalk juicers are not only superior in design and function they are a work of art that you will be proud to have on your counter top. Even the 235 model that is rebuilt with modern motor bearings and a refurbished hydraulic system is a beautiful appliance that anyone would be proud to have on their counter top. 

The Norwalk juicer is superb and it is the finest juicer on the planet. That is why I have proudly owned almost every model and why I use my own Norwalk  juicer frequently. 

If you can not yet afford the newest model I recommend you begin with a good refurbished Norwalk juicer. Once you try a Norwalk juicer you will want to upgrade to a 265 or 270 model or the eventual purchase of a 275 model just like I did.

I can understand why the factory no longer supports the now obsolete 230 and 235 models and older models. I loved my 235 back in 1970 and used it for more than a decade, replacing the motor 3 times and maintaining it often. Finally after 3 burned out motors due to my aggressive juicing routine on my old faithful 235 model -- and not being able to find another obsolete motor I had it rewound, refurbished the juicer into new condition and sold it. I then began to use the 265 I had in reserve.

To see typical refurbishing photos click here.

These earlier models can still function well but only if they have the 40 year old bearings replaced with new sealed bearings and frequently change the front motor shaft seal.  In addition changing the hydraulic fluid and worn out tired return spring is a good improvement to lengthen the life of the 235 model. The old 235 model bearings were not sealed like newer bearings on current models and there are design flaws in the old models that have since been improved. For example, in addition to the non sealed bearings that go bad often causing the motor to over heat, the short feed tube can allow your fingers to go down too far toward the cutter. The inconvenience of the screw in round grids takes more time to process juice. That said, the 235 model can still be a good juicer ONLY if it is rebuilt and you realize the inconveniences and the need for frequent maintenance. Owners of the 235 model should not delude themselves into thinking it runs well just because the motor spins. If you have not taken the 235 or older models apart as I have you just do not know the perils of owning the older model juicers. If you really have limited means I can help you rebuild your 235 juicer, but I advise that you find a way to get a newer model as soon as you are able to afford it. GOOD HEALTH is your best insurance policy. Compare the cost of poor food choices leading to doctors, medicine, hospitals and feeling bad to the cost of a Norwalk Juicer. Think about it.

Dr. Norman Walker became known as the leading expert in the field of raw juice therapy when he opened the Norwalk Laboratories of Health Research in 1910.  His research in the benefits of raw vegetable and fruit juices prompted him to begin production of a hydraulic press juicer.

The Norwalk Triturator Hydraulic Press Juicer was originally developed by Dr. Walker.  From his original designs, the development of the present-day Norwalk evolved.  This design enables you to process all growing foods quickly, easily, and efficiently.

Through the use of the Norwalk Ultimate Machine, it is possible for anyone to achieve their goal of a raw food regimen through pulp-free juice and chopped raw salads.  Through fresh raw foods, you can receive the nutrition you need - the natural way.

Make the plunge and buy a newer model Norwalk juicer as soon as you can afford one. I highly recommend the 265, 270 and the 275 models. If you have limited funds then by all means buy a 235 model BUT ONLY if you rebuild it or are lucky enough to find one already refurbished. New motor bearings, a motor shaft seal and new O rings and a fluid change on a 235 model are a MUST.

Whatever model you own I can help you refurbish it or tune it up to like new condition but do not be penny wise and pound poor. The newer models are worth the investment and will pay for themselves in time with the savings in produce costs since the Norwalk juicers make more than 50% more juice than other centrifugal juicer models. I have verified this by pressing the pulp left by the centrifugal models. By pressing spent centrifugal pulp I got 100% more juice from greens and 50% more juice from carrots. In addition to that I times the whole process using the same amount of produce on both the Norwalk and a centrifugal juicer including clean up and the Norwalk is faster every time. It takes me only 45 seconds to clean a Norwalk juicer and another 60 seconds to clean 6 cloths. When making single servings I can make 3 bottles of juice in 12 minutes -- including cleaning the cloths.
