Eureka Optima 431DX Vacuum Cleaner

The Eureka Optima 431DX offers all the power and features that an upright vacuum delivers but with half the weight. It has a comfortable grip looped handle featuring thirteen adjustable positions, thus ensuring maximum convenience when using it. The vacuum has a maximum power of 12 amps, which is pretty impressive for a vacuum cleaner that weighs only 12 pounds. We especially love how its on and off brush roll deep cleans low-pile and high-pile carpets.

Apart from carpets, this high-performance vacuum cleaner is also great for bare floors; its brush roll is gentle on bare floors. Furthermore, it comes with two onboard tools, the deluxe stretch hose, and crevice tool, to meet different vacuuming needs. Another outstanding feature of the Eureka Optima 431DX vacuum cleaner is its suction control system, which enables you to clean carpets efficiently. With the suction system, you can eliminate all kinds of debris and dirt from your carpets, including hairs.

With its 12amp motor and on and off brush roll, this bagless vacuum cleaner lets you easily clean multiple surfaces. It also lets you transition effortlessly between carpet and bare floors like tiles, hardwood, and linoleum. More so, the featured onboard accessories and flexible hose make for easy maneuvering around couch cushions and tight spots. It also features a dusting brush for dusting elevated surfaces like tabletops, bookshelves, and even ceilings.

Furthermore, the unit offers a telescoping handle that adjusts to your height and an O-shaped grip for comfortable handling. The handle comes with soft materials to ensure you don’t injure your hand while vacuuming and make cleaning more enjoyable. It is a bagless vacuum cleaner, meaning there are no bags to wash or replace, helping you save a little on recurring costs. Instead, the vacuum cleaner comes with a dust cup that you can easily empty, keeping your hands away from dirt.

Additionally, the Eureka Optima 431DX vacuum cleaner has an 11” cleaning path, a suction control switch, and allergen filtration. You can use the suction control switch to direct all the suction power to the hose or floor. Also, there’s a belt-stopped indicator to ensure your safety and a 20ft cord for moving easily between rooms. The long cord means you can move from your point to another in the house with only minimal outlet changes.

Eureka Optima 437AZ Vacuum Cleaner

The Eureka Optima 437AZ Vacuum Cleaner is a budget-friendly, lightweight upright vacuum considered a good buy. The vacuum cleaner has great suction yet is very compact and better suited for smaller areas. It works effectively on multiple surfaces, and its compactness makes it easy to store but can be pretty loud. Considering its combination of conventional upright and stick designs, you could call the Eureka Optima 437AZ a hybrid vacuum.

The Eureka Optima 437AZ is powered by a 12 amp motor, which is quite good for a vacuum cleaner like this. It utilizes dual motors, each one designed for different functions: one for suction and the other for the brush roll. Additionally, you can turn the brush roll on or off if you're vacuuming different surfaces; this feature makes transitioning between surfaces easy. The Optima 431AZ is a bagless vacuum cleaner that uses a reusable dirt container rather than a bag.

The bagless feature of the Optima 431AZ eliminates the need to keep throwing away and purchasing dust bags. While having a bagless vacuum may seem like more of a chore than having to empty dirt containers, it's still worth it. Nevertheless, the vacuum does have filters that need constant maintenance and replacement when necessary to prevent it from leaking.

The Eureka Optima 431AZ also comes with HEPA filtration, a popular feature for people suffering from allergies or asthma. This filter is highly efficient in removing dust particles and allergens from the environment, thus purifying the air. The HEPA filter can remove 99.97% of all airborne particulates that pass through it, including most pollen and allergens. Also, the vacuum cleaner comes with a 20ft power cord, which is not long enough for many users.

Most users of vacuum cleaners prefer power cords that are at least 30ft long, making the 431AZ's cord too short. Also, its cleaning path is only 12 inches, which is quite narrow, although some prefer it this way. The narrowness allows it to clean in-between furniture and very narrow spaces that larger vacuum cleaners cannot handle. Furthermore, it features a few onboard tools like the Power Paw, a dust brush, and a crevice tool or extension wand.

How do you clean the brush roll of your eureka optima vacuum?

To clean the brush roll, ensure the vacuum cleaner is unplugged; then loosen the screws to open it. The screws are located on either side of the brush roll; gently lift the cover of the base head of the vacuum. Then, carefully snip threads and hair wrapped around the brush roll with scissors. When you're done, replace the cover and latch the screws back in place; cleaning your brush roll improves suction.
