NutriBullet RX vs Vitamix S30/S50/S55

NutriBul­let and oth­er Chi­na out­sourced blenders are often pre­sent­ed in their flashy infomer­cial as true com­peti­tors of Vita­mix machines. It is very sus­pi­cious to expe­ri­enced blender users even at first look, while many inex­pe­ri­enced con­sumers can eas­i­ly be caught by pro­fes­sion­al adver­tis­ing. Nev­er­the­less, peo­ple look for the best option and, most impor­tant­ly, for the best cheap­er option; thus, NutriBul­let Rx seems real dis­cov­ery. Accord­ing to the adver­tis­ing, it is pow­er­ful, ver­sa­tile, and twice cheap­er than Vitamix.

Here is our com­par­i­son between the NutriBul­let Rx machine and the Vita­mix per­son­al gad­gets S30, S50, and S55 mod­els that will reveal the truth about all pros and cons of these well-known blenders.

NutriBullet RX Blender

nutribullet-rxThe NutriBul­let Rx comes with a very pow­er­ful 1700 watts motor but a num­ber of design flaws. The blade assem­bly shaft which goes into the dri­ve is made of plas­tic and thus has a risk of break­ing or melt­ing eas­i­ly. The blade assem­bly is also bad­ly designed and has two prob­lems — the seal­ing gas­ket is often chewed up by the blades. The blade assem­bly screw­ing thread can­not con­nect con­tain­ers prop­er­ly and thus often leaks dur­ing the blending.

The machine’s 3 con­tain­ers are also made from a very poor qual­i­ty poly­car­bon­ate mate­r­i­al that has a high risk of crack­ing when exposed to high loads. Thus con­tain­ers are not durable and need to be replaced at least once a year or more often.

The machine’s oper­a­tion is sup­posed to be sim­ple and suit­able for novice users, but in fact, it is prim­i­tive. The machine starts oper­a­tion by sim­ply drop­ping the cup on the top of the base unit and does not have any speed reg­u­la­tor, or pulse func­tion but 1 minute pre-set pro­gram for all types of blend­ing and 7 minute pre-set for mak­ing soup. Such lim­it­ed speed con­trol sig­nif­i­cant­ly reduces the range of func­tions this machine is able to perform:

  • Makes good qual­i­ty smooth­ies, includ­ing the green from leafy and tough ingredients;
  • Crush­es ice only with enough liq­uid added, this machine is not able to make snow cones, ice cream, and oth­er frozen treats;
  • Designed to make hot soup from scratch and even equipped with a ded­i­cat­ed soup pre-set pro­gram and pitch­er, but heats liq­uids to mod­er­ate 150F and the process takes so long that it is bet­ter to do using a cooker;
  • Not able to chop food, make dress­ings, sal­sas, and oth­er food prep due to the speed limitations;
  • Makes nut but­ter, but the qual­i­ty is very poor;
  • Purees food with only liq­uid added and not able to han­dle thick mix­tures well;
  • Grinds cof­fee beans and herbs but not suit­able for flour making;
  • It does not make any dough and bat­ter.

In addi­tion, it comes with a very short 1‑year lim­it­ed war­ran­ty and very unhelp­ful cus­tomer service.


Vitamix S30, S50, S55 Blenders

Vitamixs s30, s50, s55The Vita­mix has three per­son­al blender mod­els – S30, S50, and S55. All mod­els come with iden­ti­cal tech­ni­cal para­me­ters but dif­fer by the only avail­abil­i­ty of pre-set pro­gram options. The machines have mod­er­ate com­pared to NutriBul­let Rx only 790 watts motor. How­ev­er, as with all Vita­mix motors, this one is also based on ball-bear­ing tech­nol­o­gy, thus so effi­cient and func­tion­al that it is able to per­form a large range of functions.

The S30, S50, and S55 machines come with pre­mi­um qual­i­ty Tri­tan poly­ester con­tain­ers that are stress and tem­per­a­ture resis­tant. The blade assem­bly is also well-made, although it has a plas­tic col­lar and base all-met­al blade to dri­ve cou­pling; thus is very strong and durable.

The machine also comes with a well-equipped con­trol pan­el that has 10 vari­able speeds and pulse func­tions while the S50 mod­el and S55 mod­els are pro­vid­ed with an addi­tion­al 2 and 4 pre-set pro­grams respec­tive­ly. So this machine is designed to per­form a vari­ety of fol­low­ing functions:

  • Pro­duce excel­lent qual­i­ty drinks even from the tough­est and fibrous ingre­di­ents; it is more than suit­able to make green smoothies;
  • Nut milk is no prob­lem for this machine;
  • Crush­es ice with and with­out liq­uid added, able to make excel­lent snow cones, frozen desserts, and ice creams;
  • Makes excel­lent hot soup heat­ing the liq­uid fric­tion with­in 6–7 min­utes, the con­tain­ers han­dle well hot liq­uids thus suit­able for mak­ing bul­let­proof coffee;
  • Silky nut but­ter is not a prob­lem for the machine; it comes with a tam­per, which is a great help for this task;
  • Pure eas­i­ly cooked and uncooked ingre­di­ents, make excel­lent deeps and spreads;
  • Chop veg­eta­bles to pre­pare var­i­ous food prep recipes such as sal­sa, mix­es, mari­nade coleslaw, and others;
  • Grind­ing and milling any ingre­di­ent, cof­fee, herbs, and grains even pro­duce bak­ing qual­i­ty flours from hard grains;
  • Knead the dough and mix batters.

In addi­tion, this machine comes with a great per­son­al type blender with 5 years full war­ran­ty that cov­ers all wear and tear and has the best in the indus­try cus­tomer service.

How to Choose Between the Two Blenders

Vita­mix sin­gle-serv­er mod­els are supe­ri­or machines in com­par­i­son to the NutriBul­let Rx. Despite the fact, that the S30, S50, and S55 gad­gets have only 790 watts motor which is almost 2.5 times less pow­er­ful than the NutriBul­let Rx motor, Vita­mix machines com­plete­ly out­pace their func­tion­al­i­ty. The NutriBul­let Rx blender, which is equipped with such enor­mous pow­er, can only pro­duce good qual­i­ty smooth­ies and can­not even crush ice with­out liq­uid added. It is also not designed to do chop­ping tasks, pro­duce puree or han­dle any thick mix­tures. The NutriBul­let Rx soup-mak­ing sig­na­ture fea­ture is also so imprac­ti­cal that it hard­ly will be used by the major­i­ty of the customers.

While Vita­mix sin­gle-serve mod­els are able to per­form a leg­endary vari­ety of full-size Vita­mix machine tasks from excel­lent smooth­ies, hot soup to ice cream, and mak­ing bak­ing flour, so, the low wattage S30, S50, and S55 motor must be treat­ed as the advan­tage fea­ture that could save some mon­ey on the cus­tomer elec­tric­i­ty bill.

In addi­tion, Nutribul­let has quite a few con­struc­tion faults that make this machine high­ly unre­li­able. While Vita­mix’s design is so elab­o­rate that it almost does not have any weak points apart from its high price.


The Vita­mix S30, S50, and S55 are very expen­sive per­son­al blenders, but they are also the most ver­sa­tile and durable machines in this mar­ket seg­ment. Which hard­ly will require any main­te­nance out­lays over the 5‑year peri­od that is served by a full war­ran­ty with all wear and tears cov­ered.  More­over, these machines are most like­ly to serve 10 + years with­out any issues.

NutriBul­let is 1.5 times cheap­er than S30, S50, and S55 but comes with a 1‑year lim­it­ed war­ran­ty and has on aver­age 1–2 year life expectan­cy. That dur­ing the 5–10 year exploita­tion peri­od will cost con­sumers 5–6 times more than expen­sive Vita­mix machines.

There­fore, Vita­mix S30, S50, and S55 are obvi­ous choic­es for any con­sumer who is look­ing for reli­able and mul­ti­func­tion­al per­son­al blender gadgets.
