As a pet owner living in a home with a mix of plush carpets and hardwood floors, I wage a daily war. It’s a battle fought on multiple fronts: against the tumbleweeds of Golden Retriever fur that gather in corners, the invisible dust mites that trigger allergies, and the crumbs that mysteriously appear moments after cleaning. For years, I believed the solution had to be a compromise—either a brutishly powerful but clunky machine or a sleek, lightweight model that lacked deep-cleaning muscle. The idea of a vacuum that could deliver uncompromising suction, advanced filtration, and genuine versatility, all while looking good, felt like a distant dream. This constant search for the “perfect” cleaning companion is what led us to the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner, a machine that promises to blend power, hygiene, and modern design.
- Lift-Up Canister: Simply press a button to quickly transition to a lightweight pod for stairs and above floor cleaning.Voltage:120 volts.120.0 watts
- Hair Eliminator Nozzle: Brushroll automatically removes hair from the brushroll so it’s always ready to clean. This full-sized upright leaves dirt nowhere to hide while being lightweight at 14lbs...
What to Consider Before Buying an Upright Vacuum Cleaner
An Upright Vacuum Cleaner is more than just an appliance; it’s a key solution for maintaining a healthy and comfortable living environment. Its primary benefit lies in its ability to provide powerful, motorized brush-driven cleaning, which is essential for dislodging deeply embedded dirt, pet dander, and allergens from carpet fibers. Unlike canister or stick vacuums, the all-in-one design of an upright provides a robust, straightforward approach to cleaning large floor areas efficiently. For those with significant carpeting or who struggle with persistent pet hair and allergies, the deep-cleaning capability and advanced filtration systems found in models like this Kenmore can dramatically improve indoor air quality and overall cleanliness.
The ideal customer for this type of product is someone facing the challenges of a busy, active household. This includes families with children, pet owners who are constantly dealing with shedding, and individuals with allergies or asthma who need a sealed system with HEPA filtration to trap fine particles. It’s built for homes with a mix of flooring, especially those with medium to high-pile carpets that require aggressive agitation to clean effectively. Conversely, it might not be suitable for those who live in very small apartments with exclusively hard flooring, where a lightweight stick vacuum might suffice. It’s also not for someone who prioritizes cordless convenience above all else, as the cord is essential for its consistent, high-powered suction.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Consider the machine’s weight and footprint. At 14 pounds, the Kenmore BU4050 is relatively lightweight for a full-powered upright, making it easier to push and carry. However, you’ll still need dedicated closet space for storage, and its cleaning head width will determine how many passes it takes to cover a room.
- Capacity/Performance: This is where the bagged vs. bagless debate comes in. The Kenmore BU4050 uses large 3-liter bags, which excel at trapping dust and making disposal a clean, hygienic process. Performance also hinges on suction power and filtration; this model’s sealed HEPA system is a top-tier feature for capturing allergens.
- Materials & Durability: Look at the quality of the plastics, the sturdiness of the wand, and the flexibility of the hose. While most modern vacuums are primarily plastic, the quality can vary greatly. User feedback often highlights potential weak points, such as hoses that split or components that wear out, making durability a key long-term consideration.
- Ease of Use & Maintenance: A vacuum should make your life easier, not harder. Evaluate features like swivel steering, cord length, and the ease of changing bags and filters. For the Kenmore BU4050, the Lift-Up canister is a major ease-of-use feature, but some users have noted a learning curve with the bag replacement mechanism.
While the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing the Rose Gold Powerhouse: First Impressions of the Kenmore BU4050
Pulling the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner from its box, the first thing that struck us was the color. The “Rose Gold” finish isn’t just a gimmick; it gives the appliance a premium, modern look that stands out from the sea of industrial-looking vacuums. Assembly was straightforward, with components clicking together intuitively in just a few minutes without needing to pore over the manual. In hand, the vacuum feels surprisingly light for its size, living up to its 14-pound specification. The plastic construction feels solid and well-molded, though some of the onboard tool clips seemed a bit flimsy—a minor point we noted for long-term testing. The swivel steering felt fluid right out of the box, promising good maneuverability. Our initial impression was of a well-designed, thoughtfully constructed machine that successfully balances aesthetic appeal with a sense of purpose-built power.

Putting It to the Test: A Deep Dive into the Kenmore BU4050’s Performance
A vacuum’s true worth is revealed not on the spec sheet, but on the battlefield of a lived-in home. We put the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner through a series of rigorous tests on various surfaces, from shedding-pet zones to high-traffic hallways, to see if its performance matched its promising features.
Unrivaled Suction Power and Deep Cleaning Capability
The core of any great vacuum is suction, and this is where the Kenmore BU4050 truly shines. The moment we powered it on, we could feel the immense power. On our medium-pile living room carpet, the vacuum practically pulled itself forward, and the results were immediately visible. It lifted the carpet pile and extracted an almost embarrassing amount of fine dust and embedded pet hair that our previous vacuum had clearly been missing for months. This confirms a sentiment we saw from other users, one of whom wisely noted that new owners might go through bags quickly at first because “your old vacuum was not cleaning your house properly so this vacuum has to play catch up.”
This raw power is thanks to Kenmore’s PowerFlow Bag Technology, a double-wall design that ensures the vacuum maintains strong, consistent suction even as the bag fills. We tested this on hardwood floors, where it effortlessly captured everything from fine dust to stray cat litter without scattering it. However, this power comes with a caveat. The machine features an automatic floor-type adjustment and lacks a manual height setting. While this “Intuition” feature worked well on low-pile carpets and hard surfaces, we found, as another user did, that it can be overly aggressive on very plush or shag carpets. Even with the suction control valve open, it left temporary “rivets” in the carpet. This isn’t a deal-breaker, but it’s something owners of delicate or high-pile rugs should be aware of. For 90% of homes, though, the deep-cleaning capability is nothing short of phenomenal and you can see its full feature set and user reviews to learn more.
The Lift-Up Canister: A Game-Changer for Versatility
One of the standout features of the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner is its namesake “Lift-Up” technology. With the press of a button, the main motor and dust bag canister detach from the floorhead, transforming the unit into a portable, lightweight pod. This isn’t just a gimmick; it fundamentally changes how you can clean your home. Our carpeted staircase, typically a dreaded chore involving balancing a heavy upright, became remarkably easy to tackle. The canister is light enough to carry in one hand while using the wand and attachments with the other.
The included attachments add to this versatility. The Pet HandiMate tool, a small, air-powered turbine brush, was particularly effective at pulling stubborn fur from upholstery and pet beds. The dusting brush and crevice tool perform as expected, allowing us to reach ceiling corners, vents, and tight spaces behind furniture. However, we did encounter some of the same frustrations mentioned in user feedback. The hose is quite stiff and doesn’t stretch as easily as we’d like, creating a bit of resistance that can sometimes pull the canister toward you. Additionally, the onboard storage clips for the attachments feel a bit weak, and we had the dusting brush fall off a couple of times during vigorous use. These are minor ergonomic issues in what is otherwise a brilliantly versatile system.
Filtration, Allergies, and the Bagged Advantage
For allergy sufferers, a vacuum’s ability to contain what it collects is just as important as its ability to pick it up. This is where the Kenmore BU4050’s bagged design and sealed system are a massive advantage over many bagless competitors. The combination of a completely sealed system and an advanced HEPA filter means that the 99.97% of dust, dander, and pollen it sucks up stays trapped. We noticed a tangible difference in the air quality after cleaning—less dust in the air and a fresher smell in the room.
The “No Touch Bag Technology” is another excellent feature for hygiene. When the bag is full (indicated by a light, though some users have reported this indicator can be faulty), you simply press a button to release the bag directly into the trash. The bag’s collar automatically seals shut, preventing any puff of dust from escaping. It’s a clean, simple, and far more pleasant experience than knocking a cloud of filth out of a bagless canister. We did find, as some users have pointed out, that the bag compartment can be finicky to close. The trick is to press the “Dust Bag Release” button *horizontally* towards the machine, not down, when securing the door. Once we figured this out, it was simple, but first-time users might struggle briefly. We also appreciated the clear user guidance online explaining that the HEPA filter is located behind the silver front grill, while the washable foam filter is inside the bag compartment.
The “Hair Eliminator” and Other Design Quirks
Kenmore heavily promotes the “Hair Eliminator Nozzle,” which is designed to automatically remove tangled hair from the brushroll as you clean. In a home with both long human hair and prolific pet shedding, this was a feature we were eager to test. Our verdict? It’s helpful, but not infallible. After several cleaning sessions, we inspected the brushroll and found that while it had significantly less hair wrapped around it than a standard brushroll would, there was still some accumulation, particularly of longer strands. This echoes the experience of several users who found they still needed to manually cut hair off the roller. To its credit, as one user noted, the brushroll has a convenient channel that makes it easy to slide scissors underneath the wrapped hair for quick removal. So, while it reduces maintenance, it doesn’t eliminate it entirely.
Other design quirks became apparent during our testing. The machine is undeniably loud; we understood why one user mentioned using hearing muffs. It’s the trade-off for such powerful suction. The power cord, while generously long, is also quite stiff and exits high up on the handle. This can make it a bit unwieldy at times, and we had to be mindful to keep it out of our path. While these are minor annoyances rather than critical flaws, they are part of the overall user experience and worth considering before you check the latest price and availability.
What Other Users Are Saying
Across the board, user sentiment for the Kenmore BU4050 is largely positive, with many owners expressing genuine delight. One user went so far as to say, “I don’t write a lot of reviews but I am madly, deeply, truly in love with this vacuum.” The most frequently praised attributes are its incredible suction power, its lightweight design, and the game-changing convenience of the Lift-Up feature for cleaning stairs and cars. Pet owners, in particular, seem to be converts, with one pug owner noting its superior ability to handle “ever-lasting pug hair” compared to previous high-end vacuums they had owned.
However, the feedback isn’t universally glowing. A recurring critical theme revolves around long-term durability and certain features not living up to their marketing claims. Several users reported that the “Hair Eliminator” brushroll still required frequent manual cleaning. More concerning are the reports of critical components failing after about a year of use, such as a split hose or failed binding bolts on the wand, with limited options for replacement parts. Some customers also described a frustrating and lengthy warranty replacement process, leaving them without a vacuum for weeks. These mixed experiences suggest that while the vacuum offers exceptional performance out of the box, potential buyers should be aware of possible longevity issues.
How Does the Kenmore BU4050 Compare to the Competition?
No product exists in a vacuum (pun intended). To provide full context, it’s essential to see how the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner stacks up against other popular models in the market.
1. Dyson Ball Animal 3 Upright Vacuum
- Includes de-tangling technology that automatically clears wrapped hair from the brush bar as you clean
- Easy to maneuver with cleaning modes for deep carpet, low pile and hard floors
The Dyson Ball Animal 3 is often seen as the premium, tech-forward alternative. Its primary advantages are its legendary cyclone suction technology and its highly effective de-tangling Motorbar cleaner head, which is arguably more effective than Kenmore’s Hair Eliminator. As a bagless vacuum, it saves you the ongoing cost of buying bags. However, it comes at a significantly higher price point and requires emptying a dusty bin, which can be a major drawback for allergy sufferers. Someone might prefer the Dyson if they prioritize the absolute latest in de-tangling technology, have a larger budget, and don’t mind the potential mess of a bagless system.
2. Bissell Revolution HydroSteam Pet Carpet Cleaner
- HYDROSTEAM TECHNOLOGY. The ONLY carpet cleaner with the power of HydroSteam Technology.
- 2X BETTER CLEANING1. Wash & remove embedded dirt, stains and allergens in SteamWash Max Clean Mode.
It’s important to clarify that the Bissell Revolution HydroSteam is not a direct competitor, but rather a specialized tool. This is a carpet *cleaner* or “shampooer,” designed for deep, wet cleaning to remove set-in stains, spills, and odors. It cannot be used for daily dry vacuuming of dust and debris. A household would own the Bissell *in addition* to a vacuum like the Kenmore BU4050, not instead of it. A user would choose the Bissell specifically for tackling tough, embedded carpet stains and refreshing entire rooms, a task the Kenmore is not designed for.
3. Shark Rotator Professional Lift-Away NV501
- Powerful upright vacuum with Lift-Away pod for convenient cleaning of stairs and above-floor areas.
- Anti-Allergen Complete Seal Technology + HEPA
The Shark Rotator NV501 is perhaps the Kenmore BU4050’s most direct rival. It features a similar “Lift-Away” technology for portable cleaning, has powerful suction, and also includes a sealed system with HEPA filtration. The biggest difference is that the Shark is a bagless model. The choice between these two excellent vacuums comes down to a fundamental preference: bagged vs. bagless. If you prioritize the ultimate hygienic disposal and want to minimize any contact with dust, the Kenmore is the superior choice. If you prefer the long-term cost savings and convenience of not buying bags, and don’t mind emptying a dust cup, the Shark is an incredibly compelling alternative.
The Final Verdict: Should You Buy the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner?
After extensive testing and analysis, we can confidently recommend the Kenmore BU4050 Bagged Upright Vacuum Lift-Up Cleaner, but with a few important qualifications. It is an outstanding choice for households, particularly those with pets and allergy sufferers, who prioritize raw suction power and superior air filtration above all else. Its ability to deep-clean carpets is top-notch, and the Lift-Up canister provides a level of versatility that makes whole-home cleaning significantly easier. The hygienic, no-mess bag disposal system is a massive quality-of-life improvement over bagless alternatives.
However, prospective buyers should temper their expectations for the “Hair Eliminator” feature and be aware of the user-reported concerns regarding long-term durability. It has a few ergonomic quirks, like the stiff cord and loud operation, but these are reasonable trade-offs for its immense power. If your primary goal is to get your floors and air as clean as humanly possible with a versatile, user-friendly machine, the Kenmore BU4050 offers incredible value and performance. For a powerful, stylish, and deeply effective cleaning solution, we believe it’s a fantastic investment for the right home. You can find out more and secure one for your home today.
