A compact canister vacuum can make stairs, hard floors, upholstery, and quick room-to-room cleaning easier, but only if it has enough power without becoming awkward to carry. The Eureka 3670M Canister Cleaner combines an 8.6-pound body, a 1200-watt motor, a 2.5-liter bag, and several attachments in a simple corded design. It is a practical fit when you value portability and bagged debris collection more than premium convenience features. This review explains where the 3670M works well, what its limitations are, and what you should check before buying.

What Is the Eureka 3670M Canister Cleaner?
The Eureka 3670M is a compact, bagged canister vacuum built for straightforward household cleaning. Eureka lists a 1200-watt, 12-amp motor, a 2.5-liter bag capacity, an 8.6-pound weight, and a corded design. The canister format lets you keep the motor body on the floor while you guide the hose, wand, and cleaning head where you need them.
Its strongest appeal is simplicity. You get a floor tool for carpets and hard floors, plus a crevice tool and combination tool for edges, upholstery, stairs, and other above-floor jobs. A blower port adds another use for moving loose debris where vacuum pickup is not the goal.
Who Should Buy It?
Best For
- You want a lightweight vacuum that is easier to carry between rooms or up stairs.
- You prefer a bagged system that keeps collected debris contained during disposal.
- You need one machine for hard floors, area rugs, upholstery, stairs, and car interiors.
Skip If
- You want a cordless vacuum or automatic cord rewind.
- You want a bagless dust cup and do not want to buy replacement bags.
- You expect motorized floor-head features found on more complex canister or upright vacuums.
Before You Buy: The 3670M is a traditional corded, bagged canister vacuum. It gives you low weight and useful tools, but you should be comfortable with manual cord handling and replacement bags.
Key Features That Affect Cleaning Efficiency
1200-Watt, 12-Amp Motor
Eureka specifies a 1200-watt, 12-amp motor for the 3670M. That gives the vacuum the power foundation needed for routine carpet, hard-floor, stair, upholstery, and car cleaning. The key benefit is not a complicated electronics package, but steady corded power without battery runtime limits.
For you, that makes the 3670M better suited to longer cleaning sessions than a small battery-powered handheld. The tradeoff is that you still need access to an outlet and must manage the power cord as you move through the home.
8.6-Pound Canister Design
At 8.6 pounds, the 3670M is light for a full-size household vacuum body. That matters most on stairs, when carrying it between floors, or when you need to bring it outside for a vehicle. You can move the canister separately from the wand instead of pushing the full motor weight through the floor head.
The compact design also helps with storage, although the hose, cord, and wands still need their own space. If you have a small closet, plan how you will store those pieces together so accessories do not get separated.
2.5-Liter Bag and High-Filtration Design
The 2.5-liter bag gives you more debris capacity than a small handheld vacuum and keeps dirt enclosed when you remove the bag. Eureka describes the sealed bag system as a high-filtration design intended to help contain pet odors and pet dander.
The practical cost is ongoing bag replacement. A bagged vacuum can be cleaner to empty, but you should factor replacement bags into long-term ownership instead of treating the 2.5-liter capacity as maintenance-free.
Floor Tool and Above-Floor Attachments
The included floor tool handles the main carpet and hard-floor jobs. The crevice tool is better for baseboards, seat gaps, edges, and narrow spaces, while the combination tool gives you another option for upholstery and dusting. Extension wands increase reach so you do not need to bend as much for every cleaning pass.
This attachment set is one of the 3670M’s biggest strengths. It does not depend on a single floor head, so you can change the tool to match the surface instead of forcing one nozzle to do everything.
Blower Port
The blower port lets the machine push air instead of only collecting debris. That can be useful for moving loose dust or leaves from a small outdoor or garage area before final cleanup. It is a secondary feature, but it adds value for buyers who want one compact machine to handle more than floor vacuuming.
How It Performs in Real Use
Carpets and Area Rugs
On carpets and rugs, the 1200-watt motor provides the core suction needed for routine dirt pickup. The 3670M makes the most sense for low-to-moderate pile surfaces where you want strong basic suction without paying for a more elaborate powered brush system. For thick carpet or deeply embedded debris, a vacuum with a motorized brush roll may be a better fit.
Hard Floors
Hard floors are a natural match because the floor tool can handle dust, crumbs, and loose debris without the bulk of a large upright. The light canister body is also easier to pull around furniture. Use the proper floor-tool setting and avoid dragging grit under the nozzle when cleaning more delicate flooring.
Stairs and Upholstery
The 8.6-pound weight becomes more valuable on stairs, where carrying a heavy upright can be awkward. You can use the hose with the crevice or combination tool for stair edges, furniture seams, cushions, and window-area dust. Keeping the canister stable on a flat step or floor position reduces the chance of it shifting while you work.
Car Interiors
For vehicle cleanup, the crevice tool can reach between seats and along console edges, while the combination tool helps with fabric surfaces. Because the vacuum is corded, you need an outlet within practical reach. If you already have garage power, the 3670M can be more capable than a small handheld for a full interior cleanup.
Setup and Usage Tips
Start by fitting the hose, extension wand, and correct cleaning tool securely before turning the vacuum on. Match the floor tool or attachment to the job instead of using the same nozzle everywhere. The crevice tool is best for narrow gaps, while the floor tool is the better choice for broad surfaces.
Keep the bag from becoming overly full because airflow can drop as debris builds up. Check the bag during heavier cleaning sessions, especially after picking up pet hair or a large amount of dust. Also inspect the hose and tools for clogs if suction suddenly feels weaker.
Pro Tip: Keep the crevice and combination tools stored with the vacuum so you can switch tools during one cleaning session instead of making a second pass later.
Cleaning and Maintenance
The main routine expense is the disposable bag. Replace it before it is packed full, and follow Eureka’s manual for the correct bag type and installation method. A correctly seated bag helps maintain airflow and reduces the chance of loose debris entering the canister.
You should also check the hose, wand, and nozzles for blockages and clean the filter according to the product instructions. Unplug the vacuum before maintenance. Simple upkeep matters more on a basic canister vacuum because performance depends heavily on clear airflow through the bag, filter, hose, and floor tool.
How It Compares to Alternatives
If you want a similar Eureka bagged canister, the Eureka Mighty Mite 3670G is worth comparing. It keeps the same lightweight 8.6-pound idea and 2.5-liter bagged design, while Eureka lists features such as a 20-foot cord, 11-foot maximum extended reach, and onboard tool storage.
If you want to avoid replacement bags, the Eureka WhirlWind NEN110A is a more natural comparison because it uses a 2.5-liter bagless dust container and includes automatic cord rewind. The 3670M makes more sense when bagged debris containment and a simple, lightweight format matter more to you than bagless emptying or automatic cord management.
Is It Worth the Price?
The Eureka 3670M fits the budget-to-mid-range side of canister vacuum shopping. Its value comes from combining a 1200-watt motor, 2.5-liter capacity, low 8.6-pound weight, multiple tools, and a blower port without adding a complicated control system.
You get the most value if you regularly clean several surface types and want a vacuum that is easy to carry. It is less compelling if you strongly prefer cordless operation, automatic cord rewind, or a bagless system, because those convenience features are available on other models.

Frequently Asked Questions
Is the Eureka 3670M good for pet hair?
It can pick up loose pet hair from floors, stairs, upholstery, and car interiors using its suction and attachments. For deeply embedded hair in thick carpet, a vacuum with a powered brush roll may be more effective.
Can you use the Eureka 3670M on hardwood floors?
Eureka lists hard floors as a recommended use. Use the proper floor-tool setting and keep the nozzle free of trapped grit so you do not drag abrasive debris across a delicate finish.
How large is the dust bag?
The listed bag capacity is 2.5 liters. That gives you more room than a small handheld dust cup, but the bag still needs replacement as it fills to maintain good airflow.
How loud is the Eureka 3670M?
Eureka’s current 3670M product page does not publish a decibel rating. Because of that, you should not rely on an exact noise figure unless it appears in the manual or seller documentation for the specific unit you are buying.
Does the Eureka 3670M have a blower function?
Yes. Eureka lists a blower port as one of the model’s features. It can be useful for moving loose dust or leaves when blowing is more practical than vacuum pickup.
What tools come with the Eureka 3670M?
Eureka lists a floor tool, crevice tool, combination tool, hose, and extension wands with the canister. These accessories let you move from broad floor cleaning to edges, upholstery, stairs, and tighter spaces.
What warranty does the Eureka 3670M have?
Eureka’s current US product page displays a 2-year warranty badge for the 3670M. Warranty coverage can depend on the seller, region, and purchase terms, so confirm the current policy before ordering.
The Bottom Line
The Eureka 3670M is a strong fit if you want a light, bagged canister vacuum with 1200-watt corded power, a 2.5-liter bag, and tools for floors, stairs, upholstery, and car interiors. Skip it if automatic cord rewind, cordless use, or a bagless dust cup matters more to you than simple construction and easy portability.
