Electrolux EL4335B Features

Electrolux EL4335B is improved versions of Electrolux EL4335A and it features excellent performance on all floor types.

Main controls are conveniently positioned on the handle and operated by fingers and on the main cleaning head and operated by feet. Only the vacuum suction controls are positioned on the canister itself, requiring some bending in order to adjust the suction.

The main cleaning power nozzle features brushroll (controls on the handle), 3-level height adjustment system for optimal suction and cleaning performance, brushroll clean pedal/system, handle release pedal and height indicator.

Since Electrolux EL4335B is designed for people with pets in mind, power nozzle features brushroll cleaning system which is used for removing entangled pet and human hair, lint, fibers and other dirt from the brushroll, significantly helping with the maintenance of the vacuum.

Note: for optimal results, don't weight until the brushroll is fully and tightly covered with hair. Also, before the first use, be sure to thoroughly read the manual - EL4335B is easy to use units, but it is important to get accustomed to your new vacuum before the very first use.

Electrolux EL4335B features so-called 'Motion Control System' – unit is easily moved around the house thanks to the large rear wheels and a rather low center of gravity. Also, thanks to its shape, canister doesn't get 'stuck' behind the user during vacuuming.

Unit features a combined reach of 33 feet, which is enough to clean large area using single wall power socket.

Power cord is 21 feet (~6.4 m) long, cleaning hose is 8 feet ~2.45 m) long and telescopic wand is 4 feet (1.22 cm) long.

EL4335B features automatic power cord rewind system, speeding up the cleaning and storing of the unit.

Dirt bin is transparent, allowing the user to see type and amount of vacuumed dirt. Dirt bin features 'Max Fill Line' - when it is filled to the 'Max Fill Line', dirt bin must be emptied. Actually, it is recommended to empty the dirt bin more often - dirt bin features the bottom opening, making it rather easy to empty.

Air filtration is done in several stages:

- cyclonic action spins the vacuumed air, separating the dirt and air in the dirt bin,

- filter screen protects the foam filter from large particles, while foam filter removes fine air particles. Both the filter screen and the foam filters are washable,

- HEPA post-motor air filter captures even the smallest air particles, enabling the unit to release practically the clean air in the cleaned room.

EL012W costs slightly more than EL012B, but in the long run, it saves money and decrease the maintenance costs.

Also, Electrolux EL4335B is designed for picking up dry dirt only. When washing air filters, before reassembling them back into the unit, be sure that they are thoroughly dry.

Electrolux EL4335B is easy to store in both vertical and horizontal position. 

Electrolux EL4335B comes with excellent 5 Year Limited Warranty.
