If you’re deciding between the Eureka 3670H and Eureka 3670G, the good news is that you don’t need to overcomplicate your purchase. Both belong to Eureka’s Mighty Mite family of compact, bagged canister vacuum cleaners.
These vacuums are designed for everyday cleaning, particularly on hard floors, stairs, furniture, and other areas where a bulky upright vacuum can feel inconvenient.
My recommendation: Choose the Eureka 3670H if you want a lightweight, straightforward vacuum for general household cleaning. However, don’t pay significantly more for the 3670H over the 3670G based on the model number alone.
The most important things to compare are the actual accessories, warranty, included bags, seller reliability, and current price.
Neither model should be your first choice if your main priority is deep-cleaning thick carpets or removing stubborn pet hair from heavily carpeted rooms.
Let’s look at how these two Mighty Mite models compare and which one makes more sense for your cleaning needs.
1. Eureka 3670H Overview
The Eureka 3670H Mighty Mite is a compact, corded canister vacuum designed for convenient household cleaning.
One of its biggest advantages is portability. Weighing approximately 8.6 pounds according to the supplied product listing, it is considerably easier to carry around than many full-sized upright vacuum cleaners.
Its canister design also makes cleaning stairs and furniture more manageable. Instead of lifting the entire vacuum onto each step, you can position the canister nearby and use the flexible hose and extension wands.
The 3670H uses replaceable dust bags rather than a bagless collection container. This means you won’t need to shake loose dirt out of a dust cup after every cleaning session.
What Makes the 3670H Appealing?
The 3670H focuses on practical cleaning rather than unnecessary extras.
Its dual-position floor nozzle makes it suitable for moving between hard flooring and suitable low-pile carpet surfaces. Meanwhile, the extension wands help users clean areas without constantly bending down.
The included dusting brush is useful for furniture and delicate surfaces, while the crevice tool helps reach narrow spaces around baseboards, corners, and sofa cushions.
Another practical advantage is the top-mounted carrying handle. This makes moving the canister between rooms or carrying it upstairs relatively convenient.
Eureka 3670H Pros
- Lightweight and compact design.
- Generous 2.5-liter dust bag capacity.
- Convenient for stairs and above-floor cleaning.
- Includes useful everyday attachments.
- No battery charging required.
- Replaceable bags make routine dirt disposal convenient.
- Suitable for homes with a combination of hard floors and rugs.
Eureka 3670H Cons
- Requires replacement dust bags.
- The 20-foot cord may require changing outlets in larger homes.
- No powered brush roll for deep carpet agitation.
- Corded operation limits movement compared with cordless models.
- Its listed 90 dB noise rating may be a concern for noise-sensitive households.
2. Eureka 3670G Overview
The Eureka 3670G is another model in the Mighty Mite canister vacuum family.
Like the 3670H, it targets buyers who prefer a lightweight canister vacuum instead of a larger upright cleaning machine.
The 3670G is worth considering if you’re looking for a straightforward vacuum for hard flooring, area rugs, stairs, and general above-floor cleaning.
The important point is that model-number differences do not automatically indicate a major improvement in cleaning performance.
Retailer listings sometimes vary in their descriptions of Mighty Mite configurations. Before purchasing the 3670G, confirm the exact product package, included attachments, bag compatibility, and warranty with the seller.
Where Does the 3670G Make Sense?
The 3670G is worth considering for someone who wants the familiar Mighty Mite cleaning format without paying extra for accessories they may never use.
For example, if you primarily clean tile, hardwood, laminate, and occasional rugs, a basic canister vacuum with a suitable floor nozzle can be a practical choice.
The same applies to someone who needs a secondary vacuum for stairs, furniture, or smaller cleaning jobs.
However, buyers should avoid assuming that the 3670G offers better suction, filtration, or carpet-cleaning ability simply because its model designation differs from the 3670H.
4. Cleaning Performance: Is There a Real Difference?
Cleaning performance is probably the biggest concern for anyone comparing the Eureka 3670H vs 3670G.
After all, nobody wants to purchase a vacuum based on its appearance only to discover that it struggles with everyday dirt.
Both models belong to a product family built around lightweight canister cleaning.
However, suction performance should not be judged solely by motor wattage or advertised power ratings. The design of the floor nozzle, airflow, bag condition, filtration, and type of flooring also influence how effectively a vacuum collects debris.
For ordinary household cleaning, here is what matters most.
Hard Floor Cleaning
Hard floors are one of the main reasons to consider a Mighty Mite vacuum.
Unlike thick carpets, hardwood, tile, and laminate generally don’t require a motorized brush roll to loosen deeply embedded debris.
Instead, effective suction and a suitable floor attachment are usually more important.
The Eureka 3670H comes with a dual-position floor nozzle, allowing users to adapt the brush head for different surfaces.
For the 3670G, check which floor attachment comes with the exact version being sold.
If both packages include comparable nozzles, there is little reason to choose one based on unsupported claims of superior hard-floor cleaning.
Carpet Cleaning
This is where buyers should have realistic expectations.
A lightweight suction-based canister vacuum is convenient for surface cleaning, but it isn’t necessarily the best tool for removing deeply embedded debris from thick carpeting.
A powered brush roll physically agitates carpet fibers, helping loosen trapped dirt and hair.
The supplied 3670H configuration does not list a powered carpet brush.
Consequently, I would consider it more suitable for low-pile rugs and general carpet maintenance than demanding whole-house carpet cleaning.
Before choosing the 3670G, check whether its exact package offers any meaningful advantage in floor-head design.
Pet Hair Cleaning
If you own pets, your flooring makes a considerable difference.
Loose pet hair on tile or hardwood is usually easier to collect than hair embedded in carpeting or woven upholstery.
The Eureka 3670H’s hose and attachments provide flexibility for reaching furniture and corners. However, its supplied accessory list doesn’t include a dedicated motorized pet-hair tool.
This limitation matters if your dog or cat regularly sheds on sofas, rugs, or carpeted stairs.
The 3670G should be evaluated against the same requirement.
The Eureka 3670H and 3670G are nearly identical in everyday cleaning performance, so there isn’t a clear winner based on suction or cleaning ability alone. Both offer a lightweight canister design, bagged dirt collection, and convenient cleaning for hardwood floors, tiles, stairs, and low-pile carpets.
Conclusion
My recommendation is to choose the Eureka 3670H if you prefer its blue design and find it at a reasonable price. However, if the Eureka 3670G is cheaper and includes the same essential accessories, it offers equally good value.
Neither model is ideal for deep-cleaning thick carpets or removing heavily embedded pet hair because they lack a motorized floor brush.
