The SEBO Airbelt D4 is a premium canister vacuum. It feels amazingly well-built, is remarkably easy to maintain, and delivers strong performance on a wide variety of surfaces. It features a wide variety of convenience features, including a rocker switch that allows you to fine-tune its suction power, an onboard tool storage compartment, and an operating range of over fifty feet. Its three-level filtration system also makes it a good option if you suffer from serious allergies. It's somewhat heavy, and its stiff hose can make it a little tricky to maneuver in cluttered areas.
The SEBO D4 is excellent for bare floors. It easily cleans pet hair as well as small and bulky debris on this surface type, with minimal loss in suction performance as its dirtbag fills up. It also does an amazing job of clearing messes in cracks and doesn't make much noise. Build quality is excellent, and the vacuum itself is remarkably easy to maintain. The long replacement intervals for its dirtbag and filters mean that recurring costs are low, especially for a bagged vacuum. It also has a very long range and is easy to maneuver, though its stiff hose can make it hard to maneuver in tight spots.
The SEBO D4 delivers impressive performance on low-pile carpet. It's highly effective at sucking up pet hair and larger debris like sand. It also does a good job of cleaning finer material like baking soda, but you still might need to make an extra pass to clear all of it. Its power rocker switch allows you to fine-tune its suction power to a wide variety of surface types. It feels well-built, is exceptionally easy to maintain, and incurs low recurring costs. However, it is heavy, and its stiff wand can make it a little awkward to maneuver in tight areas.
The SEBO D4 is a great option for cleaning high-pile carpet. While this variant of the vacuum doesn't come with a floorhead that has a motorized or air-driven brushroll, it's still remarkably effective in dealing with pet hair and does a good job of sucking up fine and large debris, but you might still need to make an extra pass to get everything. Its highly adjustable suction power lets you fine-tune its suction force if you're having trouble pushing it around on denser carpets. That said, while it's still quite maneuverable overall, the grippy wheels on its floorhead can make it hard to push around on shag-pile carpeting, and its stiff hose is a hindrance to maneuvering in tighter spots.
The SEBO is impressively well-suited to dealing with pet hair. It easily cleans pet hair on bare floors as well as low and high-pile carpet. It does a great job sucking up pet hair on furniture with its upholstery tool attached. However, since the tool has bristles instead of the more traditional lint strips, it can be tricky to move around. Its three-step filtration system is highly effective at trapping fine particles, making it a great option if you're concerned about allergens. It's quieter than most other vacuums, which is good if your pet is sensitive to especially loud noises. Unsurprisingly, since this vacuum doesn't come with a floorhead with a brushroll and lacks any mopping capability, it isn't suitable for cleaning dried-on stains.
The SEBO D4 is great for vacuuming stairs. It's heavy, which can make it a bit of a hassle to carry up and down stairs, but its built-in carrying handle does help make this process a little less fatiguing. Its long power cord also ensures that you don't need to swap outlets when vacuuming larger staircases. It performs very well across a wide range of surface types, and you can use it in a semi-handheld configuration by detaching its wand, which is good for cleaning tighter areas.
The SEBO D4 is a very good choice for vacuuming the inside of your car. Its power cord is very long, so you don't need to park too close to an outlet for you to clean every part of your car's interior. It comes with a couple of helpful attachments; you can use its crevice tool for clearing debris in tight corners, attach its upholstery tool for cleaning messes on seats and mats or use its dusting brush to clean plastic surfaces that could scratch easily. The onboard storage compartment places all of these attachments within easy reach while cleaning. Unfortunately, it doesn't come with a miniature turbo brush, which would make it even easier to vacuum upholstered surfaces.
The SEBO D4 is a fairly solid option for workshop cleaning, though this isn't what it's for. Its strong suction force allows it to clear debris in fairly deep cracks and crevices, and it performs superbly on bare, even surfaces. It also does a great job of cleaning debris on low-pile rugs. It feels amazingly well-built too. Unfortunately, it does a terrible job cleaning stains and can't deal with liquid spills.
The SEBO D4 feels amazingly well-built. The canister body is dense, high-grade plastic, encircled by a cloth-covered air cushion to help protect your walls and furniture if you ever bump into them. Its durable rubber wheels are mounted on casters and roll very smoothly. Its telescopic wand is mainly polished aluminum and features a handle with a rubberized grip. There is one notable area of concern, as the hinge for the bag compartment door makes a noticeable cracking noise when opened.
The vacuum is very easy to take apart and reassemble for routine maintenance, and swapping tools and attachments is fairly simple. The hose can be very hard to remove from the body.
The SEBO D4 is outstandingly easy to maintain.
The SEBO D4 incurs low recurring costs.
Replacement parts can be bought from this list on SEBO's website.
The SEBO D4 is very easy to store. It's a little taller and wider than the Miele Complete C3 Alize PowerLine, but its wand does fit flat in a slot on the underside of its body. Its power cord also retracts with the press of a button. There's an integrated storage compartment at the back of the canister body for its crevice tool, mini brush, and upholstery tool.
The SEBO D4 uses impressively large dirtbags. While their actual capacity is smaller than the advertised 6 L, they're still much bigger than the 2.50 L bags used by the Miele Complete C3 Alize PowerLine. According to the manufacturer, you only need to swap in a new dirtbag every six to 12 months. The small indicator window, located just behind the hose connection port, turns orange when the bag is filled or if there's a blockage.
The SEBO D4 has exceptional cleaning range. Its power cord is very long, enabling you to clean large areas without swapping electrical outlets. Its telescopic wand also has a reasonably wide adjustment range, so you can find a height that suits your preferences.
The SEBO D4 is decently portable. Its body is quite heavy, especially compared to smaller canister vacuums like the Miele Classic C1. However, it does have a built-in carrying handle that makes it easier to pick up and move from room to room. Its wand also feels very lightweight in your hand, so it isn't too fatiguing to use for extended periods.
The SEBO D4 has quite a few convenience options. The "+" and "-" suction control buttons adjust suction power in minor increments instead of corresponding to a small number of preset settings. This wide range of adjustability allows you to fine-tune suction power to various surfaces. Unlike the Miele Complete C3 Alize PowerLine, the suction control buttons are on the handle instead of the canister body, making it easier to change settings on the fly. A mechanical indicator behind the hose attachment port turns orange if the dirtbag is full or if the vacuum is clogged. There's also a thermal cut-out switch that turns off the motor if the vacuum is overheating due to a blockage or some other mechanical issue.
The SEBO D4 comes with a few tools. There's a crevice tool for tackling debris in tight corners, a soft-bristle dusting brush for cleaning delicate surfaces, and an upholstery tool for sucking up debris on furniture.
You can use the SEBO D4 in a semi-handheld configuration by removing the telescopic wand and connecting another tool to its handle, which is handy for cleaning inside your car or hard-to-reach places.
The SEBO D4 is exceptionally effective on bare floors. When its suction power is set to the maximum, it easily clears small debris like rice and bulkier debris like baking soda. Suction power also remains consistent as its dirtbag fills up.
The SEBO D4 delivers great performance on low-pile carpet. With its suction power set to the highest level, it clears an impressive amount of fine debris like baking soda and larger debris like sand. You might need to make an extra pass to suck up everything.
The SEBO D4 does a good job of cleaning high-pile carpet. Even though this variant doesn't come with a floorhead with a motorized brushroll, it still clears quite a bit of large debris like sand and finer material like baking soda. However, you'll probably need to make an extra pass to get everything. You shouldn't run the vacuum on too high of a suction level on high-pile carpet when using the parquet brush, as it can become very hard to push around.
The SEBO D4 delivers superb pet hair cleaning performance. It easily cleans pet hair on bare floors as well as low and high-pile carpet.
The SEBO D4 has good suction power at its floorhead, making it easier to clear debris in cracks or stubborn messes. You can adjust its suction power using the rocker switch on its handle, but it's worth noting that it defaults to the strongest suction setting on startup.
The SEBO D4 has good maneuverability. The floorhead is very easy to maneuver on bare floors thanks to its smoothly rolling wheels, wide range of articulation, and low-profile design, making it easy to clean under tables and chairs. However, the grippy wheels on the floorhead can make it hard to push around on shag-pile carpeting, even when the vacuum is set to its lowest suction power level. The canister body isn't too hard to pull around. Unfortunately, its hose is very stiff, making it hard to maneuver in cluttered areas, especially when compared to alternatives like the Miele Complete C3 Alize PowerLine. Swapping out attachments is quick and simple, and the onboard storage compartment places the included tools within easy reach.
The SEBO D4 does a great job dealing with pet hair on furniture using its upholstery tool. Unlike many comparable upholstery tools, this attachment has small bristled brushes instead of lint strips to help collect debris, making it harder to push around on fabric surfaces.
The SEBO D4 is highly effective when it comes to trapping small allergens. Its filtration system combines a three-layer dirt bag, a pre-motor filter, and an exhaust microfilter that's the manufacturer advertises to be capable of trapping 99.9% of particles as small as 0.3 microns in diameter.
The SEBO D4 is excellent at cleaning debris from cracks. It easily cleans debris in shallow and medium-depth cracks when using its floorhead, though debris wedged in especially deep crevices can get left behind. You should use its crevice tool if you want to completely clear all debris in deeper cracks.
The SEBO D4 does a terrible job of removing stains. It doesn't have a brushroll to provide some level of surface agitation or any mopping capability.

The SEBO D4 is a premium canister vacuum. Compared to alternatives like the Miele Complete C3 Alize PowerLine, it uses larger dirtbags, incurs lower recurring costs, and has a much longer operating range. However, it isn't quite as maneuverable, mostly in part due to its stiff vacuum hose.

The Miele weighs less, is easier to maneuver, makes less noise, and delivers slightly better crack-cleaning performance.

The SEBO Airbelt D4 and Dyson V15 Detect are differently-designed vacuums with different intended uses. The SEBO is a corded canister vacuum, making it a better option for long cleaning sessions. It feels much better-built, is significantly easier to maintain, and does a better job cleaning debris in cracks. Meanwhile, the Dyson is a cordless stick vacuum that's a better fit for quick cleaning sessions. It weighs much less, incurs virtually no recurring costs, comes with far more tools and accessories, and performs better on carpeted floors.
The SEBO Airbelt D4 is better than the Airsign HEPA Vacuum. The SEBO is a better option for cleaning large houses. It feels better-built, uses larger dirtbags that don't need replacing as often and longer-lasting filters, has a much longer range, and makes less noise. Meanwhile, the smaller Airsign is lighter and easier to maneuver, making it a better fit for smaller living spaces.
The SEBO Airbelt D4 is better than the Miele Classic C1 for most uses. The SEBO is better-built, incurs lower recurring costs, uses much larger dirtbags, and has a significantly longer operating range. Its power rocker switch also gives you a more precise level of control in adjusting suction power compared to the Miele's power level presets. Unlike the Miele, the SEBO also features a three-stage filtration system that includes a HEPA filter. Conversely, the Miele is smaller, lighter, and more maneuverable.
The SEBO Airbelt D4 is better than the NaceCare HVR 200 Henry. The SEBO is easier to store, has a longer operating range, has a more advanced three-stage filtration system, weighs a little less, and delivers better performance on bare floors and carpets.
