The 3670M Mighty Mite is a simple, high-suction canister vacuum that has been a staple in floor care for decades. Its chassis is made from high-impact polypropylene, which allows it to flex without cracking if it is accidentally bumped or dropped. The 12-amp motor uses a traditional bypass cooling system, which helps prevent overheating during long cleaning tasks in garages or workshops.
Specifications indicate a lightweight frame and a rear blower port. By moving the hose to the back of the vacuum, the unit can blow debris out of tight spaces or dry surfaces. To keep the motor clean, it is recommended to use synthetic "Style MM" bags and ensure the cardboard collar is firmly seated behind the retention clips to prevent dust from escaping into the motor housing.
This vacuum is known for its high noise level and simple friction-fit plastic wands, which can become loose over years of use. It is a highly effective tool for hard floors and low-pile utility rugs, but it lacks the filtration gaskets found in modern high-end canisters. Maintenance is easy, as the housing can be opened with a few screws for DIY repairs or cleaning.
For those who need a similar compact canister but require a higher level of noise reduction and a specialized tool for pet hair, the Eureka 3670G includes an additional turbine tool.
Reliability through simplicity is a key theme for many of the older designs still available in the upright and canister vacuums category.
