|Pros||Powerful suction pump, gentle on food, manageable size and weight||Integrated bag roll and cutter, limited overheating issues, auxiliary suction hose||Designed for heavy use, easy clean-up, decent ease of use features||Tender with delicate foods, solid value||Good with delicate foods, fairly good value|
|Cons||Narrow seal, overheats quickly, touchy touch screen||No drip tray, So-so suction power||Bulky, a little rough on food, narrow seal||Can’t seal a ton of bags successively, slow vacuuming/sealing action||Not the most convenient, average sealing performance|
|Bottom Line||This relatively inexpensive unit is packed with convenience features, is easy to operate, and has a soft touch for delicate foods||This affordable and convenient unit can seal up to 30 bags in a row while remaining gentle on tender food||If a machine capable of sealing in bulk is what you’re after, this convenient, though a bit bulky, machine has staying power while remaining easy to use||This NutriChef offers above-average performance particularly in delicate foods assessment||While we didn’t find too many issues with the Koios, there are far better products out there for the same price|

Our Analysis and Test Results
In a competitive class of vacuum sealers, the Mueller established itself as a leader for having a steady but gentle action. This machine makes quick work sealing up foods as it has a fast-acting pump that won't leave you hanging. Additionally, it has a responsive control interface that makes it easy to pulse the pump for the soft treatment of delicate items. As if these achievements were not enough, the machine's manageable size is matched by its price tag.
The sealing performance metric looks at all of the aspects of quality sealing except suction which is addressed separately. We ran these machines through several tests for suction speed with various foods being packaged. We also looked at the number of continuous bags that the units could seal before the accumulated heat from the sealing element required a cool-off period. Finally, we looked at the width of the heat seal as wider seals are more effective at maintaining vacuum. All told, the Mueller received a slightly above-average score for its sealing performance.
Our sealing analysis is broken up into four sections covering speed, continuous sealing volume, seal strength, and the ability to maintain its suction gains between pump pulses. For the speed evaluation, we use four foods of varying consistency (ground beef, bread, rice, sausage links) and time the full vacuuming and sealing cycle. The Mueller was a leader in this series of tests as all of its times were well below a minute as well as being well below the class average. As for maintaining suction pressure during the sealing process, the Mueller delivered a perfect performance.
Conversely, the Mueller did not fare so well in the other sealing performance tests. Specifically, the unit has a rather narrow heat seal — 2 mm to be exact — and the unit overheats after sealing just 9 bags. These pitiful performances offset the steller sealing time and vacuum holding results resulting in an average score.
When you really get down to it, vacuum sealers are all about convenience. These simple machines make it easier to buy in bulk and keep food fresh. Fewer trips to the store mean a saving in time and cash. So, when one buys a machine of convenience one doesn't want the machine to come with a new set of inconveniences. This metric identifies all the nuisances common to these machines and rates them on how thoroughly the problems are resolved. Specifically, we look at size and weight, whether the bags and cutting tool are integrated. We also assess the user interface, the ease of clean-up, and the presence of an auxiliary suction pump. Taking all these aspects into account, we can say that the Mueller provides an average level of convenience to users.
There are a lot of factors at play here, so let's be clear. The Mueller has many helpful features. However, its lack of onboard bag storage and bag cutter dragged it into a middling position in this evaluation. Other than that, the unit is lightweight (just 2.7 lbs), it has an auxiliary pump, it has effective and easy to operate controls, and the sealing process is largely automated. So, if you don't mind getting out a roll of bags and a pair of scissors when you're working, this machine has everything else that one could want to ease them through the sealing process.
While many foods that are good candidates for vacuum sealing are not what we'd describe as delicate, we wanted to know which machines are gentle on food for when the occasion to seal-up tender items arises. This analysis focuses on the units' ability to control suction rate through pulsing the suction pump on and off, and how the overall sealing process affects the test food (two slices of white bread). Make no mistake, the Mueller is a total boss such that we literally can't think of a better performing product.
The Mueller received top marks for its treatment of delicate food because, above all, the unit pulled the air from the package evenly such that air trapped in the bag had time to work its way out without having to compress the food. Also, the on/off button is responsive, instantly turning off the pump when pushed, while maintaining suction. This feature allows the user to work in increments that, in the end, preserve the integrity of, in this case, the soft, airy bread.
Unlike other portions of this review, the suction power test is an entirely objective analysis of the amount of negative pressure that the sealers can exert on a vacuum bag as measured in inches of mercury (in. Hg). The Mueller is a leader in the class due to its ability to pull an impressive 19 in. Hg of pressure. We made this analysis with our custom built suction gauge that mounts to the vacuum bag for consistent and accurate readings.
Value is often a personal assessment made by a consumer. However, we try to iron out the subjectivity and make the assessment a matter of price versus performance. From this perspective, the Mueller's above-average performance in our analysis contrasted with its below-average price point make it easy to definitively say this is a value, nay, a high-value item.
This thorough review of the Mueller vacuum sealer addresses every practical aspect of this machine's functionality. More than just a basic test drive, we conducted structured, reproducible evaluations of the suction power, the time to seal, as well as ease of use. Moreover, the above review structures the details of this machine's performance relative to its peers. Bottom line, this review aims to make your comparative shopping experience straightforward and effective.
