Eureka 3670M Canister Vacuum Review: Tested on Hard Floors and Pet Hair

Most canister vacuums are either lightweight and weak, or powerful and heavy. The Eureka 3670M is one of the cheaper ones trying to be both. At 8.6 pounds with a 12-amp motor, it makes a real case for itself in hard-floor homes. We used it for three weeks in a home with two cats, laminate floors, one medium-pile area rug, and a full set of stairs. Here is what we found.

Verdict: A genuinely practical hard-floor canister for tight budgets. Suction is strong for the price, the bag system keeps dust contained, and the 8.6-pound body makes stairs and overhead cleaning easy. Thick carpet and noise-sensitive homes are where it struggles. 8.6/10. Best for: Renters and homeowners with mostly hardwood, tile, or laminate who want a light canister that does not feel cheap. Skip if: Most of your home is medium or plush carpet, you have small children or pets who startle easily at loud appliances, or you need cordless convenience.

At a Glance

What We Liked

Suction for a Lightweight Canister

The 12-amp motor pulls harder than you would expect from an 8.6-pound machine. On our laminate floors it lifted cat hair from along the baseboards in a single slow pass. We ran it over a section of the floor we thought was clean and watched the bag fill. That is the kind of result that earns trust. On bare tile in the kitchen, it picked up fine debris we had missed with a broom.

Easy to Carry Everywhere

Eight and a half pounds is the key selling point, and it earns it. Carrying the canister up a flight of stairs mid-clean takes one hand. That matters for anyone living in a multi-story home or apartment where hauling a full upright gets old fast. The handle is well-positioned and the body is compact enough to fit on a step beside you while you work.

Bag System That Actually Contains Dust

Bagless vacuums dump a cloud of fine particles when you empty them. The 3670M uses replaceable bags, and the swap is clean: turn, pull, seal, done. The 2.5-liter capacity lasted us about four days of daily use in a two-cat home before the suction started to drop. Five bags come in the box, which covers a few months of normal use.

Long Reach with the Wand Attachments

Two extension wands stack to reach ceiling fans, the top shelves of bookshelves, and the gap behind the refrigerator. We used the dusting brush on the blinds and the crevice tool inside the car. These are the kinds of spots where a stubby upright vacuum never goes. The reach is genuinely useful, not just a checkbox.

Value at This Price

Budget canisters often feel like budget canisters the moment you touch them. The 3670M is plastic throughout, but the plastic does not flex or creak. The hose connection holds firm. At roughly half the price of a mid-range cordless stick, you get more suction, more attachments, and no battery to replace in three years.

Where It Falls Short

Loud Enough to Wake a Napping Kid

This is the complaint that shows up again and again in buyer reviews, and we confirmed it. The 3670M is genuinely loud, noticeably louder than most cordless vacuums and most modern uprights. If you have a baby sleeping in the next room or a pet that bolts at appliance noise, plan your cleaning sessions around that. It is not unusually loud for a bagged canister of this price, but it is louder than the current category average.

Struggles on Thick Carpet

On our medium-pile area rug, the 3670M sealed to the surface and fought back when we pushed it. Suction is high enough that the floor head wants to stick. On low-pile or flat-weave rugs it performed fine. On anything thicker, it became a workout. If half your home is carpet, this machine will frustrate you.

Wand Connections Can Pop

The plastic extension wands connect with a friction fit rather than a locking mechanism. In normal use they stayed together. When we pushed them into tight corners at an angle, one popped apart mid-stroke. It is easy to reconnect, but it interrupts the cleaning rhythm. A simple quarter-turn lock would fix this entirely.

No Auto Cord Rewind

The 3670M has a manual cord. You wind it yourself around the built-in hooks on the body. After three weeks of daily use, this had gone from mild inconvenience to the thing we actively disliked most. Every competitor in this tier offers retractable cords. At this price it is understandable, but worth knowing before you buy.

Real-World Performance

Hardwood Floors with Two Cats

This is where the 3670M is best. Cat hair along the baseboards, under the sofa, and in the gap between the fridge and the cabinet came up cleanly. The floor head glides smoothly on laminate and does not scratch. After a week of daily passes, the floors felt cleaner than they had with our previous upright on the highest suction setting.

Stairs

Carrying an upright up a staircase is awkward. Carrying the 3670M up a staircase is fine. We used the crevice tool in the corners where each step meets the riser, and the dusting brush on the carpet runner. It took about eight minutes to do a full 14-step flight. The light body made a real difference here.

Overhead and Above-Floor Cleaning

Stacked with both extension wands, the reach in our tests was about five feet. Ceiling fan blades, the top of a tall bookshelf, and the cobwebs in a high corner all came clean. The suction did not drop noticeably at that extension length. This is where the corded design pays off: no battery drain from extended overhead cleaning.

Medium-Pile Rug

Honest answer: mediocre. The 3670M can vacuum a medium-pile rug, but it takes more effort than it should. You feel resistance with every push, and embedded cat hair in the pile did not fully lift on the first pass. On a flat-weave kitchen rug it worked fine. On a 6-by-9 medium-pile living room rug it was a struggle.

How It Compares to Alternatives

If you want a similar lightweight canister with better carpet capability, the upright vacuum category has stronger brush-roll options at a similar price. For an all-hard-floors home with no pets, the 3670M is hard to beat at this price.

If you already own a Dyson or Shark cordless, the 3670M fits a different role: whole-home deep cleaning, stairs, and overhead work where battery life is a constraint. It is not trying to replace a Dyson V15. It is trying to replace the reason you still grab a corded vacuum for specific jobs.

If lightweight and hard-floor-focused describes your needs but you want something bagless, our best vacuums under $100 roundup has a few comparable options. If noise is a hard dealbreaker, check our sealed HEPA picks, which include a couple of quieter uprights with similar suction.

Who Should Buy It

The 3670M is a good fit if you live in an apartment or house that is mostly hardwood, tile, or laminate, you have pets that shed, and you do not want to spend $250 on a cordless that needs a new battery in three years. At this price, the suction-to-weight ratio is genuinely good.

Skip it if carpet is a significant part of your home. The suction that makes it great on hard floors becomes a liability on thick pile, and the noise level will irritate anyone in the house during a cleaning session. A bagged upright with a brush roll will serve carpeted homes better.

At this price point, you get a 12-amp motor, a clean bag system, a full set of attachments, and a body light enough for stairs. You do not get cordless convenience, a retractable cord, or quiet operation. If the trade-off works for your home, this is a capable machine that earns its spot in the canister vacuum category.

FAQ

Is the Eureka 3670M good for pet hair?

Yes, on hard floors. It picks up cat and dog hair from hardwood, laminate, and tile cleanly. On thick carpet, pet hair embedded in the pile is harder to lift and requires multiple slow passes. If your pet mostly sheds on bare floors, it works well.

Does the Eureka 3670M have a HEPA filter?

No. The 3670M uses allergen filtration bags, which capture a meaningful amount of fine dust, but the system is not sealed HEPA. If sealed filtration is a requirement for allergies or asthma, look at vacuums with certified sealed HEPA systems. Our allergy vacuum guide covers the options.

How often do I need to replace the bags?

In our testing in a two-cat home with daily use, a bag lasted about four to five days before suction dropped noticeably. In a lighter-use household with no pets, a bag should last two to three weeks. The box includes five bags to start. Replacement bags are widely available online.

Can the Eureka 3670M vacuum stairs?

Yes. The 8.6-pound body is one of the best arguments for this machine on stairs. You carry it with one hand while you vacuum with the other. The crevice tool fits the edge where each step meets the riser, and the suction is strong enough to pull debris out of low-pile stair carpet.

Is the Eureka 3670M loud?

Louder than average for a home vacuum. Buyer reviews consistently mention noise as the main complaint, and we found the same in our tests. It is not unusual for a corded canister at this price, but it is louder than most modern cordless vacuums and mid-range uprights. Plan cleaning sessions when noise is not a concern.

What attachments come with the Eureka 3670M?

Two extension wands, a crevice tool, and a dusting brush. The wands stack for above-floor reach. There is no motorized brush or pet tool included, so if you need a powered brush for embedded carpet hair, you would need to buy one separately or choose a different model.

Bottom Line

The Eureka 3670M is a practical machine for a specific home type: mostly hard floors, light budget, and a preference for corded power over cordless convenience. The suction is real, the bag system is clean, and the weight makes it easy to carry around a full home or up the stairs.

It is not the right pick for carpet-heavy homes, noise-sensitive households, or anyone who wants the ease of cordless vacuuming. But for what it is designed to do, it does it honestly. If you want to see how it stacks up against other budget options, our pet hair vacuum roundup covers several alternatives in the same price range.
