Most of the lineup gets a "Sound Level" row in dBA, with no setting attached. It sits in the spec table of every canister and upright page, and the owner's manuals that could be opened repeat it under technical details; the AIRBELT K manual, for one, prints "Sound level 63 dBA" on the same line as "Technical details may be subject to change." No suction setting, distance or test standard is named, and the row never says if it records sound power or sound pressure. Most pages cover two or three models with one figure between them. The AIRBELT E page splits its range: "E1, 2 - 58 dBA/E3 - 62 dBA".
A stated basis turns up once, in the owner's manual for the commercial-grade 300 and 350 MECHANICAL: "Values determined to EN 60335-2-69: Sound pressure level LpA 76 dB(A)", with "Uncertainty KpA 2 dB(A)". EN 60335-2-69 is the European safety standard for vacuum cleaners for commercial use. Nothing comparable appears in any household SEBO document.
A named setting also turns up once. The cordless BALANCE A1 is "69 dB on Power Level 1" in one paragraph of its page and "70 dB at Power-level One" in another.
The A in dBA weights a reading toward how people hear; the dBA explainer covers what that changes. Those last two figures stay out of the main rankings, the MECHANICAL because it alone has a basis and the BALANCE A1 because it has a setting and a different unit. Canisters and uprights get separate lists as well. They share a spec table row, yet nothing on sebo.us says they were measured the same way.
How loud is a SEBO canister vacuum?
Between 58 and 63 dBA, across eight AIRBELT canisters in three ranges, all corded and bagged.
| Sound Level | Model | Floor tools | Note |
|---|
| 58 dBA | AIRBELT E1 Kombi | Combination nozzle | Straight suction, knob on the canister body |
| 58 dBA | AIRBELT E2 Turbo | Air-driven turbo head, parquet brush | Straight suction, knob on the canister body |
| 62 dBA | AIRBELT E3 Premium | ET-1 electric power head, parquet brush | |
| 63 dBA | AIRBELT D4 Premium | ET-1 power head, parquet brush | One figure for the D4 and D1 on the D page |
| 63 dBA | AIRBELT D1 Turbo | Air-driven turbo head, parquet brush | |
| 63 dBA | AIRBELT K3 Premium | ET-1 power head, parquet brush | One figure for all three K models, on the page and in the manual |
| 63 dBA | AIRBELT K2 Kombi | Combination nozzle | |
| 63 dBA | AIRBELT K2 Turbo | Air-driven turbo head, parquet brush | |
Five dBA separates the E1 and E2 from every D and K model. Most people would notice that step in the same room, though it falls well short of half as loud, since halving or doubling loudness takes about 10 dB. The single dBA between the E3 and the D4 or K3 is too small to choose on.
Only the E range shows, on SEBO's own table, what a power head adds: 4 dBA, from the straight-suction E1 and E2 to the E3. The D and K pages each print one number for the whole range. Whether the straight-suction D1 Turbo and K2 models run quieter than the D4 and K3 is left open, and this page does not guess.
Size settles the rest.
| Range | Body weight | Reach from the outlet | Bag |
|---|
| AIRBELT E | 11.4 lbs | 37 ft | .92 gal. |
| AIRBELT K | 12 lbs | 37 ft | .8 gal. |
| AIRBELT D | 15.9 lbs | 52 ft | 1.5 gal. |
The K is also the one range whose table reads "HEPA Filtration Available Yes".
Eight household uprights, one decibel apart
| Sound Level | Models | Suction motor | Brush |
|---|
| 68 dBA | FELIX Premium, DART | 1000 watt | ET-1 power head with a 175 watt brush motor |
| 69 dBA | AUTOMATIC X4, X4 Boost, X7 Premium, X8 | 1300 watt | "Brush Motor N/A", brush height set automatically |
| 69 dBA | ESSENTIAL G4, G5 | 1300 watt | "Brush Motor N/A", four manual brush heights |
All eight are corded and bagged. The FELIX and DART both lift off their power head to work as a hand-held vacuum. Head widths split 12 inches for the X4, X7 and G4 against 15 inches for the X8 and G5, and the X7 page also describes an X7 Premium PET, with a turbo brush, a nine-foot extension hose and an odor microfilter, under the same 69.
One dBA is too small to hear reliably, and with no setting named it may be no difference at all. Treat the eight as a tie and shop on features: steering and variable suction on the FELIX, automatic brush height on the AUTOMATIC X, 15 inch heads on the X8 and G5, and a HEPA option on the AUTOMATIC X and ESSENTIAL G that the FELIX and DART lack.
Two commercial MECHANICAL uprights at 76 dBA
"Sound Level 76 dBA" is what the 300 and 350 MECHANICAL page lists, and their shared owner's manual is the only SEBO document found that explains how a figure was taken: "Values determined to EN 60335-2-69: Sound pressure level LpA 76 dB(A)", "Uncertainty KpA 2 dB(A)". These are, in SEBO's description, "commercial-grade, upright vacuum cleaners" that are "entirely mechanical, instead of electronic", with a 39 ft external cord that can be replaced without tools. Household figures come with no basis, so ranking the MECHANICAL against them would set unlike numbers side by side. Coverage is for residential use only: "No warranty is provided for these SEBO machines that are used commercially."
The BALANCE A1 is SEBO's only cordless vacuum and the only one whose figure names a setting. It also gets two numbers. "Operates quietly at only 69 dB on Power Level 1," reads the product description, while the Quiet Operation feature lower down says "With a noise level of just 70 dB at Power-level One". The owner's manual repeats 69; the brochure, 70. Power Level 1 is the lowest of three, and the other two get no figure. On battery, it "can operate uninterrupted for 48 minutes at Power-level One or up to 20 minutes at Power-level Three".
Plain dB, not the dBA of the spec tables, puts the BALANCE A1 in a group of one. Other makers' sticks are in the cordless stick vacuum guide.
The warranty is shorter as well. A seal on its page reads "2-year parts warranty, 2-year labor warranty, and 1-year battery warranty", and the Onyx Collection page applies SEBO's standard seven-year motor and five-year parts and labor coverage to every SEBO vacuum "except the CE12 SOFTCASE and BALANCE A1". Yet SEBO's warranty page and policies summary still describe seven years on the motor for all models. Confirm the terms with the seller before buying.
What makes one SEBO louder than another
No figure by setting exists, but the pages and the numbers point to a few causes.
The floor head is the clearest. On the E range, the ET-1 power head arrives with a figure 4 dBA above the combination nozzle or turbo head.
Exhaust comes next. The textile-covered AIRBELT bumper "diffuses exhaust air, which contributes to its ultra-quiet performance", and the FELIX and DART exhaust microfilter "absorbs motor noise, resulting in extremely quiet operation". The AUTOMATIC X, ESSENTIAL G and MECHANICAL pages make no quiet claim at all.
Then suction. Every AIRBELT canister and the FELIX have variable suction; the DART, AUTOMATIC X, ESSENTIAL G and MECHANICAL list "Variable Suction Control No". There is no figure for a low setting anywhere, and the AIRBELT K manual pushes the other way: "For optimal cleaning and brushing, operate the machine at the maximum suction power setting and push the power head slowly over the carpet." Which setting the published figures describe is never stated.
Running low has one side effect. "The 'bag full or clog' light works correctly only at full power," the same manual warns, so a canister kept turned down for quiet needs a spell at full power now and then to check the bag. For the rest of the upkeep that holds a SEBO near its out-of-box sound, see why your appliance got louder.
SEBO's names for its quiet parts
| SEBO's name | Where it appears | What SEBO claims for it |
|---|
| Textile-covered soft-foam bumper | Every AIRBELT canister | Diffuses the exhaust air, as well as protecting walls and furniture |
| Innovative Exhaust Filter, an S-class exhaust microfilter | FELIX, DART | Absorbs motor noise |
| Soft start | Every AIRBELT, AUTOMATIC X, ESSENTIAL G, FELIX, DART and BALANCE page | Motor life only: "The vacuum's gradual power-up capability extends motor life." |
| Variable suction control | A knob on the E1, E2, D1 and K2 canisters, a slider on the E3 and K3 handles, two buttons on the D4 handle, a control on the FELIX handle | A low end for "delicate tasks, such as curtains" |
| Brush roller off switch | E3, D4 and K3 handles, FELIX and DART power heads | Straight suction on fine rugs and hard floors, with no figure |
Soft start claims no noise benefit. The D4's LED "rotates slowly" at lower power, a quick way to see where its suction is set.
No prices online, and the seller decides the warranty
Vacuum prices appear on its product pages, SEBO's FAQ says, but none of the vacuum pages opened on October 10, 2026 showed one. Sales go through authorized dealers, listed on a dealer locator, and the 30-day test drive covers "All products purchased directly from this website".
Household use carries "Seven Years Motor - Five Years Parts and Labor", plus a lifetime warranty on the AUTOMATIC X drive belts; the BALANCE A1 is the exception covered above.
Where the vacuum comes from can undo that. The warranty page says it "applies only to SEBO products purchased from Authorized SEBO Dealers located in the United States of America." A free bonus on the Onyx Collection page extends select models to ten years on the motor, ten on non-wear parts and seven on labor, registered with a code from a dealer, and it does not apply to SEBO vacuums bought from third-party websites "such as Amazon and Walmart.com". Before buying through a link on this page, check that the seller is an authorized SEBO dealer.
Setting SEBO against other brands
This page ranks SEBO only against SEBO. Other makers' canisters are in the quietest canister vacuums guide, every vacuum type is in the quietest vacuums, and the Tineco vacuum decibels page does this same job for Tineco. Because the household figures carry no setting, distance or basis, read why decibel ratings rarely compare across brands and sound power vs sound pressure before holding a SEBO number up to another maker's. The decibel chart sets the numbers beside everyday sounds.
Models left off the list
The CE12 SOFTCASE, a lightweight upright, has a brochure, owner's manual and parts list on SEBO's downloads page but no page in the US product directory, and no figure for it turned up on sebo.us. Onyx Collection vacuums, versions sold only in dealers' stores with the warranty bonus above, print no figures of their own. Neither do the ET-1 and ET-2 power heads sold separately, the DUO carpet cleaning machine or the DISCO floor polisher.
