D Series Features (Both Models)
- FLAT-TO-THE-FLOOR, 3.5-INCH PROFILE
- A low, cleaning-head profile makes reaching under furniture and beds easy!
- THREE FULL-SIZE, ON-BOARD TOOLS
- A crevice nozzle, an upholstery nozzle, and a dusting brush are always on-board and ready for use. Also, many optional attachments are available that can be fitted to the telescopic tube or the hose handle.
- SOFT-START FEATURE
- The vacuum’s gradual power-up capability extends motor life.
- TAPERED SUCTION HOSE WITH ROTATING CONNECTION
- The D1 and D4 feature a unique tapered suction hose, which further increases airflow velocity and minimizes clogs. And a brilliantly designed hose-to-canister connection allows 320° rotation of the suction hose, providing easier user movement and machine maneuverability.
- FULL-SIZE CANISTER VACUUM
- The D4 is a full-size canister vacuum that offers a giant filter bag and an extra-long power cord.
- UNMATCHED, 40-FOOT CORD AND 52-FOOT OPERATING RANGE
- Its cleaning radius is amazing! Large areas can be cleaned without changing electrical outlets. Plus, the seven-foot suction hose provides superb user and machine maneuverability.
- PUSH-BUTTON CORD REWINDER
- Its super-long power cord rewinds by simply pressing a button.
- FULL BAG OR CLOG INDICATOR
- When a full bag, clog, or excessively dirty microfilter is detected, an indicator in the window turns orange, which warns the user of inadequate airflow to cool the motor. If this condition persists, its thermal cut-off switch will shut down the motor after a short duration of time.
- PATENTED AIRBELT BUMPER
- The textile-covered, soft-foam bumper protects furniture, walls, and the vacuum itself from incurring scratches and scuffs during use. The bumper also diffuses exhaust air, which contributes to its ultra-quiet performance.
- FOUR RUBBER-COATED CASTOR-WHEELS, MOUNTED ON BEARINGS AND STEEL AXLES
- The rubber-coated castor-wheels glide easily and gently over all floor types, providing exceptional maneuverability and protection of floor surfaces.
- CONVENIENT PARKING AND STORAGE AIDS
- After the work is done, the suction hose and telescopic tube, with parquet brush or combination nozzle, can be firmly stored on the canister’s underside (shown) or backside housing.
- GIANT, 1.5-GALLON FILTER BAG
- The large filter bag is convenient and economical because fewer bag changes are needed and closing its built-in hygiene cap prevents dust from escaping during bag disposal.
- THREE-STEP FILTRATION
- It features a pre-motor filter, a three-layer AeraPure™ bag, an S-class exhaust microfilter, and a tightly sealed casing, which prevents dirty air from escaping through its seams.
D4 Unique Features
- DURABLE POWER HEAD WITH MANUAL HEIGHT ADJUSTMENT AND AMAZING STEERING ABILITY
- The D4 model comes standard with the commercial-grade ET-1 electric power head, which is 12 inches wide, effectively cleans both carpets and hard floors, easily removes pet hair, offers four-level manual brush height adjustment, and its 180â° steering ability provides amazing maneuverability.
- EASY BRUSH ROLLER REMOVAL, USER WARNING LIGHTS, AND AUTOMATIC OBSTRUCTION SHUT OFF
- The ET-1 has easy, tool-free brush roller removal, a handy clog removal door, and a red warning light with automatic shut off, if the brush roller is jammed or obstructed. Also, its warning light remains illuminated during use when brush height is set too high for optimal cleaning, or when the brush roller should be replaced due to excessively worn bristles.
- LED SUCTION-POWER INDICATOR
- This technology allows the user to optically monitor the vacuum’s suction power. When using lower power settings, the LED light rotates slowly. When using higher power settings, the light rotates more quickly. When the power is set to standby mode, the light slowly blinks back and forth, left to right.
- DUAL-CONTROL HANDLE
- The D4’s remarkable dual-control handle has two soft-touch buttons that provide convenient suction adjustment, from maximum power for normal cleaning to minimal suction for delicate tasks, such as curtains. The hose handle also offers an on/off switch for the power head’s brush roller when straight suction is required, such as cleaning fine rugs.
D1 Unique Features
- TURBO HEAD AND PARQUET BRUSH, BUT NO POWER HEAD
- The D1 has a telescopic tube and suction hose without an integrated power cord, so it does not accommodate an electric power head. Instead, it comes with an air-driven turbo head for rugs and a parquet brush for hard floors.
- SUCTION-CONTROL KNOB ON CANISTER BODY
- Because the D1 has a hose and telescopic tube without a power cord, its suction-control knob is located on the canister body, not the handle, and an LED light illuminates when it is powered on, but it does not include the optical suction-power indicator available on the D4.
