The Eureka 3670G Mighty Mite is a solid contender among low-priced canister vacuums, especially for users who have primarily hard floors. It's not the best choice for cleaning carpets as it doesn't have a powered brushroll, but it does perform exceptionally well at removing pet hair from hard surfaces and furniture. It's extremely durable, with most owners saying it lasts for years; complaints of malfunctions are fairly isolated among the hundreds of rave reviews.
Small but mighty; perfect for bare floors. The Eureka 3670G Mighty Mite isn't included in any professional tests, but there are nearly 1,500 owner reviews between Walmart.com and Amazon.com, most of which praise the Mighty Mite's performance despite its compact size. It's not ideal for cleaning carpets, but it's a great choice for small spaces that have mostly hard floors. It also performs well at removing pet hair, even from area rugs, which can sometimes be difficult to vacuum with models that have too much suction power. The Mighty Mite also has a standout feature that differentiates it from other canister vacuums: Its blower port can be used to blow debris from floors in garages or other workspaces.
Small, compact and easy to maneuver. At just 8.6 pounds, the Eureka 3670G Mighty Mite is easy to maneuver, easy to carry and compact enough that it's easy to store. That said, its short 20-foot power cord means the plug must be relocated to clean larger areas. It does have a low profile, so it slides easily under most low-sitting furniture, and its swiveling floor head is easy to operate. It also has onboard tool storage for the included dusting brush/upholstery tool and crevice tool, and two easy-to-use extension wands. Suction control is conveniently located on the handle, but it's possible to hit the control accidentally during use.
Loud but expected, owners say. The Eureka 3670G Mighty Mite is noisy, owners say, but most of those who mention it don't see it as a major problem. One Amazon.com user says, "A little noisy but not too excessive considering how well it cleans." However, another comments, "I would suggest wearing ear plugs."
No HEPA filtration. The Eureka 3670G Mighty Mite offers neither standout eco-friendly features nor HEPA filtration via either the bags or the filters. Its dust bags are small, so they require replacement more frequently than larger canister vacuums, but they offer triple (non-HEPA) filtration to help preserve air quality and prevent dirt particles from re-entering the environment.
Overall, a highly durable machine. The Eureka 3670G Mighty Mite is backed by a one-year limited warranty. Many user posts at Amazon.com and Walmart.com say the Mighty Mite will last for years. Some say the bags are hard to find in stores, but it is possible to obtain them online. The bags are small, so frequent changes may be necessary for larger jobs, but bags cost less than $1 each. Among the few comments we read on customer service, owners find it friendly and helpful but report some slowness with getting replacement parts.
In more than 800 reviews, Amazon.com owners give the Eureka 3670G Mighty Mite an average rating of 4.2 stars out of 5. They like its good suction, maneuverability and low cost. However, some complain that it is flimsy, noisy and underpowered, and the tools could be better.
