Bottom line

If you don't want to spend a lot of money on a vacuum but want an upright capable of cleaning both hard floors and carpets, the Eureka Boss Smart Vac 4870 is a good choice. It weighs more than 21 pounds, so keep that in mind if you plan to use it on stairs. Different model numbers come with varying attachments, such as powered mini-heads with pet-hair removal attachments and a rising visor for stairs.


Surprisingly powerful for the price. Editors at one professional testing organization say the Eureka Boss Smart Vac 4870 is excellent for bare floors, carpet and pet hair. It also earns an excellent score for emissions and good scores for noise and airflow. The Eureka Boss Smart Vac boasts a wide 15-inch cleaning path. Owners posting feedback to sites like and are impressed with the strong suction considering the low price of this upright vacuum and say it's great for pet hair. Opinions are mixed on noise, with some saying it's super-quiet while others claiming it's irritatingly loud.


Not as feature-packed as pricier models. The Eureka Boss Smart Vac 4870 is sold under a few different model number extensions, indicating varying attachments and colors. The base model, the 4870MZ, comes with a powered nozzle with a lifting visor for cleaning stairs with ease, as well as a crevice tool, upholstery nozzle and dusting brush. HEPA filtration keeps the air cleaner. The brushroll adjusts to seven different height settings and can be deactivated, but the manual adjustment is cumbersome. Airflow can be redirected to the hose, but there are no suction-strength settings. 

Ease of use

Heavy and bulky, with good intentions. The Eureka Boss Smart Vac 4870 has an adequate 30-foot power cord. While it's not self-propelled, owners posting feedback to sites like and say it feels as though it is. There are many complaints about the weight of this 21.5-pound vacuum, and some users say it's bulky and awkward to maneuver. Others say it's simply too heavy to use on stairs and that the attachments won't stay in place. The bags are easy to change, however. The handle adjusts, but several reviewers say the release is difficult to operate.


Easy maintenance, but service repairs are inconvenient. The Eureka Boss Smart Vac 4870 uses HEPA filters, which cost around $20; the pre-motor filter costs around $3. Both should be replaced every six bag changes. Dust bags cost around $6 each but can be purchased in bulk. A maintenance pack can be purchased from Eureka for $65, containing six vacuum bags, one HEPA filter, one motor filter and one drive belt. There are some complaints of malfunctioning units and brushrolls that simply quit. Customer service honors the one-year warranty, but service centers can be more than 100 miles away for some users.
