Eureka Pet Lover Mighty Mite


This is a canister type vacuum and it has excellent suction to pick up hair and clean carpets. We have this machine also and like it a lot due to its versatility,
power, and effectiveness. Because it is a canister, it is more transportable than a traditional upright. The vacuum weighs less than 9 lbs and has hepa filtration.
The pet hair tool (Power Paw Turbo) is excellent and does an awesome job of removing pet hair from furniture and clothes!
The Eureka Mighty Mite is available for less than $100 at Amazon.
