The Eureka Mighty Mite is a budget-friendly canister vacuum. It's a corded, bagged design with a very simple, straight-suction floorhead. It has two separate friction-fit extension wand pieces, allowing you to adjust its height. Surprisingly, for a vacuum in its class, it features a powerful 12-amp motor. There's a relatively spartan tool assortment, consisting only of a crevice tool and a combination upholstery tool/hard-bristle brush.
Our Verdict
The Eureka Mighty Mite is a good option for a house. It's surprisingly powerful, and its corded canister design allows you to clean your entire home without concern for runtime. Its straight-suction floorhead easily sucks up fine material on bare floors and medium and large material on carpets. However, the floorhead pushes around medium and large debris on bare floors, and its low agitation on carpets means you'll have to make several passes to lift deeply embedded fine material. Unfortunately, the filter performance is inadequate, as the bag filter allows significant quantities of dust to pass through and out of the exhaust, leading to poor air quality and dust scattering throughout the room. At least disposing of the sealed bag effectively removes all the retained dust without making a mess. Additionally, the lack of agitation makes it difficult to remove pet hair from carpets.

The Eureka Mighty Mite is an okay choice for a small apartment. This fairly small, light, corded canister vacuum won't have a problem getting around tight apartments, and you can tuck it away into a fairly small space when you're done cleaning. Carpet and bare floor pickup performance is decent for the most part. However, its straight suction floorhead plows around medium and large debris on hard floors, and its lack of agitation means it can't lift fine material embedded in carpet, and barely moves pet hair at all. Additionally, this vacuum has poor filtration, which negatively impacts air quality. Its dirtbag is so porous that it blows a lot of dust straight out of the exhaust, into the air, and onto everything. At least emptying the sealed dirtbag keeps the dust well-contained, though.

The Eureka Mighty Mite is adequate for stairs. It's a lightweight vacuum, and while it doesn't have a significantly long cord or hose range, it can cover a flight of stairs. It offers decent pickup on both bare and carpeted areas, but the straight suction floorhead plows around medium and large debris on bare surfaces and lacks agitation to lift embedded fine material and pet hair on carpets. Its worst issue in a cramped stairwell is its poorly-performing filter, which blows dust right through the exhaust, into the air, and all over the stairs.

The Eureka Mighty Mite is good for cars. This vacuum is lightweight and easily portable. Since its wand is made of two pieces, you can easily shorten it to reach more difficult areas. While it doesn't have the longest cord or hose, you can store its tools and brushes onboard, so you don't have to keep going back to grab more parts. Automotive carpet pickup is decent due to its strong suction, although you may need to make a few passes to remove fine debris that is embedded. Pet hair removal is easy with the mini brush tool. The vacuum is very easy to maintain, and it can be stored in a fairly compact space. The build quality is passable for an entry-level vacuum, making it sturdy enough to last.

The Eureka Mighty Mite is decent for bare floors. It easily picks up finer material on this type of surface. That said, its straight suction floorhead is too low to the ground to pass over medium and bulky debris, so it plows it around and requires you to pick up the floorhead repeatedly as you clean.

The Eureka Mighty Mite offers satisfactory pickup performance on carpets. It has no issue picking up medium and large debris on any kind of carpet, but its straight-suction floorhead barely provides any agitation, leaving embedded fine material behind. You'll have to make several passes.

The Eureka Mighty Mite delivers sub-par pet hair pickup performance. The straight-suction floorhead hardly agitates carpets at all, so most pet hair remains on the carpet, and it even gets pressed in deeper. By contrast, vacuuming pet hair on upholstered furniture with the mini brush tool is highly effective, as the brush effectively picks up almost all pet hair. However, hair tends to accumulate in the bristles, so you'll need to remove it regularly.

The Eureka Mighty Mite has a bad impact on air quality. The dirtbag is so porous that it allows most dust particles to pass right through it and out of the exhaust, resulting in poor air quality and scattering dust throughout your living space. Fortunately, emptying this vacuum is much cleaner. You can seal the dirtbag and dispose of it without kicking up much dust at all.

Popular Vacuum Comparisons
The Eureka Mighty Mite 3670M is a budget-level canister vacuum designed for cleaning bare floors, such as garages. It's about the most powerful vacuum you can buy in its price class; its suction power rivals that of the much more expensive Miele Complete C3 Alize. The Eureka's straight suction floorhead isn't ideal for carpets; the upright Kenmore Intuition Bagged is a more carpet-oriented competitor with a height-adjustable floorhead and a powered brushroll. However, the greatest issue with the Eureka Mighty Mite is its dirtbag. It's so porous that it lets large amounts of dust pass straight through to the exhaust. The Kenmore doesn't have such a problem since it has a HEPA filter dirtbag. You can even get better filtration with a bagless filter in the budget Wyze Cordless Vacuum S.

The Eureka Mighty Mite and the BISSELL Zing Bagless Canister have different strengths. The Eureka is a bagged canister vacuum that offers improved bare floor performance, reduced maintenance requirements, lower recurring costs, and a slightly lighter construction. The bagless BISSELL feels slightly sturdier and performs better on both low- and high-pile carpets.
The Eureka Mighty Mite is superior to the BISSELL Zing Bagged Canister. The Eureka is a little easier to maintain, performs noticeably better on low-pile carpets and bare floors, and has lower recurring costs with a longer range. Conversely, the BISSELL deals with finer debris on high-pile carpets more effectively.
The Miele Classic C1 is a more versatile canister vacuum than the Eureka Mighty Mite. The Miele feels better built, is easier to maintain, and offers a wide variety of convenience features, including a self-winding power cord and a tool clip that sits at the base of its wand. It also has a more powerful motor and is more maneuverable despite its heavier weight. However, the Eureka is still a good choice if you're looking for an inexpensive alternative that weighs less and occupies less space when not in use.
The Eureka Whirlwind Bagless Canister and the Eureka Mighty Mite are similarly performing canister vacuums. The Whirlwind feels better built and incurs lower recurring costs due to its bagless design. However, the Mighty Mite has more tools, is a bit more portable, and has a longer range. User maintenance is much easier, and its dirtbag holds more debris. Both vacuums have similar straight-suction heads that struggle with larger debris.
