Eureka 3670M vs. Eureka 3670G: Lightweight Canister Vacuum Comparison & Review

When shopping for a compact, budget-friendly, and powerful vacuum cleaner, canister models remain a top choice for homes with bare floors, stairs, and tight spaces. Among the most popular compact canister vacuums on the market is the legendary Eureka Mighty Mite series.

In this detailed 2,000-word comparison guide, we take a close look at two key variants from this lineup: the Eureka 3670M Canister Cleaner and the Eureka 3670G Canister Vacuum. Both units feature the iconic bright yellow cylindrical body, lightweight portability, and integrated blower ports, but key differences in motor power, filtration type, speed settings, and included accessories set them apart.

Below, we break down every specification, compare their real-world cleaning efficiency, list their pros and cons, and crown an overall winner.

1. Quick Comparison Overview

Here is how the Eureka 3670M and Eureka 3670G compare across core specifications

2. In-Depth Look: Eureka 3670M Canister Cleaner

The Eureka 3670M is built for homeowners and apartment dwellers who want straightforward, fuss-free cleaning without dragging around a heavy upright.

Key Features & Design Highlights:

• Ultra-Lightweight Body: Weighing only 8.6 pounds, the 3670M is remarkably easy to carry around using its top-mounted handle. It effortlessly moves up flights of stairs, making it ideal for multi-level homes.
• Included Dust Bags: The 3670M package comes bundled with 5 individual dust bags, letting you start cleaning right out of the box without immediate extra purchases.
• Foam Filtration System: Uses a foam motor-protection filter alongside sealed dust bags to capture fine dust particles and keep exhaust clean.
• Integrated Blower Port: A standout feature of the Mighty Mite series is the rear circular exhaust port. By attaching the hose to the rear vent instead of the front intake, the vacuum instantly converts into a powerful leaf or garage blower to clear debris from workshops, patios, and garages.
• Compact Storage: Features rear-mounted cord wrap hooks and on-body attachment storage, keeping all accessories organized in tight closets.

3. In-Depth Look: Eureka 3670G Canister Vacuum

The Eureka 3670G (often designated as the Pet-Friendly or Higher-Wattage variant) builds on the classic Mighty Mite chassis by boosting internal motor specs and control versatility.

Key Features & Design Highlights:

• 1400-Watt (12 Amp) Motor: Driven by a robust 1400-watt motor, the 3670G delivers high suction for stubborn pet hair, dirt, and cat litter stuck in floor crevices or low-pile rugs.
• Two-Speed Power Level Control: Unlike single-speed models, the 3670G includes 2 power settings. This allows you to dial down suction power when cleaning delicate surfaces like drapes, throw rugs, or lampshades, and ramp up to full power for bare floors and entrance mats.
• Cloth Filter System: Features a durable cloth filter system designed to handle fine pet dander and larger dirt particles efficiently.
• Bare Floor & Surface Safety: Safe for hardwood, laminate, tile, and vinyl, equipped with non-marring smooth wheels to prevent floor scratches.
• Versatile Attachment Suite: Includes an angled crevice tool, dusting brush, and dual-purpose floor nozzle with smooth pivot action.

4. Head-to-Head Feature Comparison

A. Motor Power & Suction Performance

• Eureka 3670M: Delivers reliable daily suction rated at 87.4 inches of water lift. It handles hard floors, tile, laminate, and low-pile rugs with ease.
• Eureka 3670G: Takes the edge in overall motor output with its 1400-watt / 12-amp rating. If you frequently vacuum heavy debris, pet dander, or cat litter, the extra power on the 3670G helps pull stubborn particles out of carpet fibers and baseboard gaps.

B. Speed Settings & Control

• Eureka 3670M: Operates on a single power speed (1 level). While simple to operate, you cannot adjust suction power when vacuuming delicate fabrics or light rugs that might stick to the nozzle.
• Eureka 3670G: Features 2 speed levels. The lower speed is ideal for drapes, upholstery, and small throw rugs, preventing the nozzle from suction-locking onto fabrics.

C. Filtration & Dust Management

• Eureka 3670M: Uses a foam filter combined with sealed disposable paper bags. Changing bags is clean and sanitary—simply throw away the full bag without producing a cloud of dust.
• Eureka 3670G: Utilizes a cloth filter structure alongside dust bag options. The cloth filter offers great durability and protection for high-pet-hair households.

D. Versatility & Blower Function

Both models feature the famous integrated blower port located on the rear exhaust grille. Reconnecting the flexible hose to the rear transforms either machine into an outdoor or workshop blower, perfect for clearing dirt off garage floors, drying car surfaces, or blowing leaves off porches.

5. Pros and Cons Comparison

6. The Final Winner: Which Eureka Vacuum Should You Buy?

Both the Eureka 3670M and Eureka 3670G are remarkable budget vacuums that prove you don’t need to spend hundreds of dollars to keep your floors spotless. However, when comparing features head-to-head, one model offers superior versatility.

🏆 Overall Winner: Eureka 3670G

The Eureka 3670G wins as the overall superior choice.

Its 1400-watt (12 Amp) motor provides noticeable extra suction, making quick work of pet hair, ground-in dirt, and debris. Furthermore, the inclusion of 2 power speed settings gives it a major practical advantage over the 3670M. Being able to drop down to low suction when vacuuming curtains, couch cushions, or light area rugs prevents annoying nozzle lockups and makes whole-house cleaning much smoother.

🥈 Best Value Starter Pack: Eureka 3670M

If you want the simplest operation possible and love getting extras out of the box, the Eureka 3670M is an outstanding runner-up.

The inclusion of 5 sealed dust bags right inside the package means you won’t need to shop for replacement bags for months. It offers the exact same ultra-lightweight 8.6 lb body, compact size, and blower port functionality as the 3670G at a straightforward, single-speed price point.

Summary Recommendation:

• Buy the Eureka 3670G if: You have pets, need higher motor power, want 2 speed options for delicate fabrics/rugs, and clean multiple surface types.
• Buy the Eureka 3670M if: You want a complete starter kit with 5 bags included, prefer simple 1-touch cleaning, and need a lightweight canister for basic hard floor maintenance.
