The D4 Premium Onyx sits on top of 4 casters that all rotate a full 360 degrees. This evenly disperses the weight so there are no tipping issues. Most canisters only have 3 casters. To help maneuverability further, the 7-foot hose rotates 320 degrees. This helps the canister take sharp corners with great ease. Finally, the hose itself is clog resistant by design. The electrified hose is tapered from start to finish for superior air flow and less required maintenance.
The D4 Premium Onyx is part of SEBO’s Onyx Collection and comes with an extended warranty of 10-year non wear parts, 10-year motor. Finally the vacuum comes with a 9 foot extension stretch hose and air driven hand turbo for cleaning stairs and pet hair off furniture, an upgraded parquet brush and a flexible crevice tool for cleaning underneath appliances.
The AIRBELT D4 Premium Onyx lists for $1579 and is SEBO’s top of the line, most expensive vacuum. Compared to its competitors, it is a bargain. Other brands’ canisters it competes with are as expensive as $1599 even though their manufacture’s warranties are not nearly as long.
