The Blendtec Classic 575 with the WildSide+ jar is a full-size blender available in several bright colors and variants to fit your needs. It's able to process snow-like ice, which is excellent for mixed drinks and it's super easy to clean, especially as its Spoonula can get into crevices and pull out any food left behind. It also has five preset speeds as well as a timer. However, it doesn't always fully process food, and it can leave chunks behind. It also doesn't come with a personal-sized smoothie jar, which some may find limiting.

Our Verdict

8.4 Multi-Purpose

The Blendtec Classic 575 is good for multi-purpose use. It can quickly make snow-like ice, but it struggles a lot more to blend fibrous fruit and vegetables. It can hot blend, though, which is nice if you want to make a chunky soup. It's also decent at making almond butter, but it struggles to produce a smooth texture.

Pros
  • Outstandingly easy to clean.
  • Comes with Spoonula for scooping as much as possible from the jar.
  • Well-built design.
Cons
  • Doesn't fully process food and can leave medium-large sized chunks behind.
  • No individual-use jars.
8.8 Smoothies (Single Serving)

The Blendtec Classic 575 is fair for smoothies and protein shakes. It struggles to process fibrous fruit and vegetables, producing a foamy and leafy blend. On the upside, if you like to put ice in your smoothies, it can easily process it into a snow-like texture. It also has a decent build quality and is very easy to clean.

Pros
  • Outstandingly easy to clean.
  • Well-built design.
Cons
  • Doesn't fully process food and can leave medium-large sized chunks behind.
  • No individual-use jars.
9.7 Smoothies (Multiple Servings)

Pros
  • Well-built design.
Cons
9.6 Ice Crushing

The Blendtec Classic 575 is excellent for ice crushing. It can quickly create snow-like ice that's perfect for any mixed drink. It also comes with a Spoonula utensil, so you can easily get all the ice out.

Pros
  • Well-built design.
Cons
9.7 Soups

The Blendtec Classic 575 is good for soups. It can hot blend and it's outstandingly easy to clean as it comes with a Spoonula utensil that lets you safely scoop out soup. However, it struggles to process fibrous food like kale well. It also doesn't come with personal-sized jars either, so you won't be able to blend soup to take with you on-the-go.

Pros
  • Outstandingly easy to clean.
  • Can blend hot food.
  • Comes with Spoonula for scooping as much as possible from the jar.
  • Well-built design.
Cons
  • Doesn't fully process food and can leave medium-large sized chunks behind.
7.7 Professional Use

The Blendtec Classic 575 is good for professional use. It's decently well-built and design features like grippy feet or a Spoonula help make blending easier. It can also hot blend and it produces snow-like ice. However, while it can process almonds into nut butter, it produces a crunchy spread. It has a hard time blending fibrous fruits and vegetables too, resulting in a leafy and foamy smoothie. On the upside, it's very easy to clean.

Pros
  • Outstandingly easy to clean.
  • Comes with Spoonula for scooping as much as possible from the jar.
  • Well-built design.
Cons
  • Doesn't fully process food and can leave medium-large sized chunks behind.

The Blendtec Classic 575 is a less bulky blender than the Ninja Mega Kitchen System BL770, but its base still takes up some space on your counter or in your cupboard.

Build Quality

The Blendtec 575 is decently well-built and its blade and motor assembly feel very solid. This variant comes with a 'Spoonula' or a hybrid spoon/spatula, which is designed to easily scoop out food from the uniquely shaped jar without damaging the blades. It also has grippy feet to keep the blender from moving around too much if you're blending something more intense like nuts or frozen bananas on high speed.

However, some parts of the blender feel a little cheap such as the control panel and the display. The display cover even appears to be peeling off of our test unit, which doesn't look or feel nice. There's also an exposed circuit board on the underside of the base, which you can see through a vent. If you're looking for a better-built full-size model, try the Vitamix Explorian E520.

The Blendtec Classic 575 blender has two blunt blades. Unlike the Smeg BLF01's blade assembly, they can't be removed from the jar. On the plus side, you can put the jar and blades in your dishwasher.

The Blendtec 575 has a power cord that should be long enough to reach an outlet on your counter. However, there isn't a stowaway compartment to hide the cable when you're not using it, which is a little disappointing.

This blender whips up a disappointing smoothie. It doesn't process fibrous leafy greens like kale well, and as a result, it leaves behind medium-sized chunks instead of liquifying them. It also struggles to fully blend frozen fruit such as bananas. Even though there's a dedicated smoothie preset, you may get better, more drinkable results using it on high speed. If you're looking for a blender that can make a better smoothie in less time, check out the NutriBullet Blender Combo or the Ninja DUO.

The ice crushing performance of the Blendtec Classic 575 blender is outstanding, and is well-suited for making slushed cocktails on a hot day. It can easily make snow-like ice quickly and evenly.

The Blendtec 575 is satisfactory at making almond butter. As it struggles to fully process the almonds, it makes a crunchy, gritty spread. Some of the almonds can also get stuck beneath the blade and need to be manually mixed back in, which is a bit of a pain. If you want a full-sized blender that's better at making almond butter, take a look at the KitchenAid K400 or the Blendtec Chef 600.

The Blendtec 575 has a self-clean function as well as a dedicated smoothie cycle mode. You can also adjust the blend cycle's timer. By default, each of the speed settings runs for 50 seconds, and then the blender stops. However, you can raise the duration of the cycle to 60 or 90 seconds, but you won't be able to control its speed during these cycles.

Ease Of Use
Cleaning

The Blendtec Classic 575 is amazingly easy to clean. You can easily reach below the blades to get to any remaining pulp or gunk or you can put the whole jar with the blades into the dishwasher. If you're making something a little more messy like almond butter or soup, the included Spoonula can help you scoop everything out of the jar, making it even easier to clean.

Differences Between Sizes And Variants

The Blendtec Classic 575 comes in a couple of variants with different accessories. We tested the black Spoonula variant, but there's also a white Spoonula variant and a black variant that comes with a recipe book. You can also purchase the blender separately, and it comes in several different colors such as caribbean blue and poppy red which can help add a splash of color to your kitchen. We expect all of these variants to perform similarly to our test unit.

Keep in mind that there are also two blender jar variants available: the FourSide jar and the WildSide+ jar. The FourSide jar is the original jar by Blendtec. It holds up to 32 oz, and you may find some Blendtec Classic 575s with this jar. The newer models come with the WildSide+ jar, which can hold up to 36 oz and is designed for blending frozen ingredients better and in a shorter time. We tested the variant with the WildSide+ jar, but your results may vary if you're using the FourSide jar.

Compared To Other Blenders

The Blendtec Classic 575 is a full-size blender that can add a splash of color to your kitchen thanks to their several color variants. Unlike other full-sized blenders like the Ninja DUO, it can process hot food like roasted vegetables into soup and it's amazingly easy to clean. There are also a few variants that come with a Spoonula, which can help you scoop out food left behind. However, it struggles a bit with fibrous fruits and vegetables like kale, which doesn't produce the best-textured smoothie.

Vitamix Explorian E310

The Vitamix Explorian E310 is better than the Blendtec Classic 575 for most purposes. It has a significantly better build quality. It's also better at processing small batches of fibrous ingredients and much better for making thick mixtures like nut butter. On the other hand, the Blendtec has a bigger capacity and does a slightly better job of crushing ice.

Vitamix A3500

The Vitamix A3500 is better for most purposes than the Blendtec Classic 575. The Vitamix has a much better build quality and comes with a tamper. It makes smoother, more spreadable almond butter, silkier smoothies, and crushed ice with a better texture. On the other hand, the Blendtec is much easier to clean. 

Vitamix Explorian E520

The Vitamix Explorian E520 is better for most purposes than the Blendtec Classic 575. The Vitamix is much sturdier and does a much better job of processing hard ingredients like nuts. On the other hand, the Blendtec is easier to clean by hand and has a bigger 90-ounce capacity.

Blendtec Designer 725

The Blendtec Designer 725 is a better blender than the Blendtec Classic 575 for most uses. The Designer 725 has a much better build quality, makes a more uniform smoothie, and is better at crushing ice. Nevertheless, the Classic 575 can produce more spreadable almond butter and can be used for hot blending.

Vitamix 5200

The Vitamix 5200 is a better full-size blender for multi-purpose use than the Blendtec Classic 575. The Vitamix has a significantly better build quality and produces almond butter and smoothies with a better texture in less time. It also uses a speed dial, so you have a bit more control over your blending speed. However, the Blendtec is easier to clean.

Vitamix A2300

The Vitamix A2300 is better for most purposes than the Blendtec Classic 575. The Vitamix has a much better build quality, a greater number of speed settings, and is also Bluetooth-compatible, which gives you access to a variety of preset modes via a companion app. It makes better-blended smoothies and smoother, more spreadable almond butter. However, the Blendtec makes crushed ice with a better texture in less time. It's also significantly easier to clean.

Vitamix 7500

The Vitamix 7500 is a better blender than the Blendtec Classic 575. The Vitamix has a much better build quality and does a significantly better job of making smoothies, almond butter, and crushed ice. However, the Blendtec is much easier to clean by hand.

Ninja Smart Screen

The Blendtec Classic 575 is a better blender than the Ninja Smart Screen if you're looking to do some hot blends. The Blendtec also has a 2-part lid that allows you to add some ingredients mid-mix. On the other hand, if you're looking for a blender for smoothies or almond butter, the Ninja is a better option, even though it's not the best. However, the Ninja is outstanding when it comes to crushing ice down to snow-like quality.

Vitamix A3300

The Vitamix A3300 is better than the Blendtec Classic 575. The Vitamix has a much better build quality and comes with a tamper. It does a better job of making almond butter, smoothies, and crushed ice. It also has more speed settings and is Bluetooth compatible, so you can access preset modes via a companion app. On the other hand, the Blendtec has buttons for preset modes, including a dedicated self-clean mode.

Ninja DUO

The Ninja DUO is a better blender for making smoothies than the Blendtec Classic 575. The Ninja makes silky smoothies in less time, can produce smoother almond butter, and its crushed ice is fine and snow-like. It also comes with a personal blending jar, so you can quickly take your blend with you on the go. However, if you're looking for something more versatile, the Blendtec is better-built, can process hot food, and it's way easier to clean messes from it. It also comes in several bright colors to better suit your kitchen decor.

Smeg BLF01

The Blendtec Classic 575 is better than the Smeg BLF01. The Blendtec has a significantly better build quality, can make decent almond butter, and produces snow-like crushed ice in less time. It's also much easier to clean by hand.  However, the Smeg does a better job of incorporating kale into a smoothie, but you have to add more liquid to the jar than the Blendtec.

Blendtec Chef 600

The Βlendtec Chef 600 and the Βlendtec Classic 575 have different strengths, and you may prefer either depending on what you're looking for. The Chef 600 makes significantly smoother, more spreadable almond butter and does a much better job processing ingredients like kale in smoothies. On the other hand, the Classic 575 is better for crushing ice and has a significantly better build quality. It's also much easier to clean by hand.

Vitamix 5300

The Vitamix 5300 is better than the Blendtec Classic 575. The Vitamix has a much better build quality and does a better job of processing hard ingredients like nuts. It's marginally better at crushing ice and processing small batches of ingredients for something like a single-serve smoothie. On the other hand, the Blendtec's main jar has a bigger capacity. Its controls include automatic blending programs, and its jar, lid, and blades are all dishwasher-safe.

NutriBullet Blender Combo

The NutriBullet Blender Combo is better for making smoothies than the Blendtec Classic 575. The NutriBullet feels better built, it comes with two personal jars so you can take your drinks with you on the go, and it produces a significantly better smoothie in less time. It's also much better for making soups. However, the Blendtec is easier to clean.

KitchenAid K400

The KitchenAid K400 is a better multi-purpose blender than the Blendtec Classic 575. The KitchenAid feels better built, and it can process almond butter and smoothies quicker and with a better texture. It also has a speed dial, which gives you a bit more control, and it's not as loud at max speed as the Blendtec. However, the Blendtec is easier to clean, and it can produce snow-like ice. It also has an on/off toggle, which is handy.
