KitchenAid Professional Series 5.5-Quart Bowl-Lift Stand Mixer (KSM55SXXX)
Reviewed / updated: Sep 10, 2026
KitchenAid's bowl-lift line brings the die-cast metal body and the power hub of the tilt-head Artisan to a sturdier chassis built for dough. The 5.5-quart bowl locks onto lift arms at three points instead of tipping back, which keeps it steady under stiff bread and lets the motor deliver roughly double the peak power at the bowl above speed 2. It is the heaviest machine in this catalog and there is no pouring shield in the box, but for anyone who kneads regularly it is the most capable KitchenAid here, and it takes every attachment the Artisan does.
The most capable KitchenAid here: bowl-lift stability plus the full attachment hub.

Our take
The bowl-lift design is the reason to choose this over a tilt-head KitchenAid. Instead of the head tipping back, a lever raises the bowl to meet the beater and the bowl locks in at three points. That rigidity matters when a dough hook is dragging a stiff loaf around: the machine stays planted, the motor runs cooler, and KitchenAid quotes roughly twice the peak horsepower at the bowl compared with its KSM150 tilt-head above speed 2.
Everything else is familiar KitchenAid. The body is die-cast zinc, so it has real mass — about 25 pounds, the heaviest here — and the front power hub takes the full catalog of KitchenAid attachments, from pasta rollers to grinders. You get 11 speeds including a dedicated half-speed for folding in delicate ingredients, plus a coated flat beater, coated dough hook and six-wire whip in the box. There is no pouring shield included, which there should be at this price.
In the reviews, owners consistently describe it as heavy, solid and quiet for the power, and several specifically mention two loaves of sourdough or double cookie batches without the machine struggling. The recurring complaint is the bowl handle, which more than one owner calls uncomfortable to grip. A few note the bowl is smaller than they expected; 5.5 quarts is mid-sized, not large.
Strengths
- Bowl-lift chassis stays steady and runs cooler under heavy bread dough
- Die-cast metal body; the most substantial KitchenAid in this comparison
- Full KitchenAid power hub — every KitchenAid attachment fits
- 11 speeds with a dedicated half-speed for folding
Weaknesses
- Heaviest machine here at about 25 lb; a permanent counter resident
- No pouring shield in the box at this price
- Only a 1-year (replacement) warranty
- Owners repeatedly call the bowl handle uncomfortable to grip
Ideal for: Regular bread and enriched-dough bakers who want KitchenAid's build and attachment ecosystem on a chassis made to take repeated heavy kneading.
What owners say
Owners describe it as heavy, well built and quiet for the power, with several saying it handles two loaves of sourdough or double cookie batches without strain. The most common criticism is the bowl handle, which multiple reviewers find uncomfortable to grip; a few also expected a larger bowl.

It’s a beaut, Clark!
This beauty is everything I expect from a KitchenAid stand mixer. It has the classic quality, functionality, and aesthetics I know and love about these mixers. The noise is moderate - not loud but you know it’s running. It’s VERY heavy and large but I expect that as they are indicators of quality and durability. I’m very okay with giving it a prominent and permanent place on my countertop since it’s size and weight make it difficult to store. I love the creamy matte color. It fits in perfectly with my kitchen and will for a lifetime because of its neutrality. The attachments have the classic, durable white coating - not the new kind they’ve started using on other KitchenAid mixer attachments with the coating that flakes off. My one complaint is the handle on the bowl. It’s not at all comfortable to grip and seems like a cut corner to reduce production cost. Otherwise, so far, so good. I got it for an amazing price and no longer have to knead bread dough by hand so I’m happy!

Very heavy duty
For years I’ve had a cheep stand mixer and when I first used this one I could tell that it is a way better model. I absolutely love this one. It’s just the right size for me. I can make two loaves of a large loaf of sourdough and it’s perfect. The machine as well as the attachments are very durable. I will use this for years to come

Amazing!
I love it! Slightly bigger then my old one, which I like. I bake a lot & wanted the larger bowl & it does not disappoint. I can easily make double batches of cookies. This mixer does not struggle with some of my thicker doughs that my old mixer was starting to struggle with. I still have my smaller KitchenAid but wanted to upgrade....I was getting concerned that after over 20years, it might die on me while in the middleof using it. I do NOT want to be without my KitchenAid mixer, lol.

Nosie
It is noise but works good. The bowl is smaller than I thought so I will look into getting a bigger and deeper one. But I do like it
