Trilobite – a class of arthropods that lived on earth about 250-560 million years ago. Many received nourishment by vacuuming the ocean beds for small animals and particles. Their backs were hard, and they are perhaps today’s best known fossils and can often be observed embedded in stone in walls, staircases and floors. This ancient creature has served as a source of inspiration for the futuristic design of Trilobite.

Trilobite – classe d'arthropodes ayant vécu sur Terre il y a environ 250 à 560 millions d'années. Plusieurs d'entre eux se nourrissaient en aspirant les petits animaux et les particules qui se trouvent au fond de l’océan. Ils étaient dotés d'une coquille très solide et sont peut-être les fossiles les plus connus aujourd'hui, puisqu'on retrouve souvent leurs restes incrustés dans les murs, les escaliers et les planchers de pierres. La conception futuriste du Trilobite est inspirée de ces créatures de la Préhistoire.

Trilobites es una clase de artrópodos que habitó la tierra entre 250 y 560 millones de años atrás. Muchos de ellos obtenían su alimento al aspirar pequeños animales y partículas desde el fondo marino. Su parte posterior era dura y son quizá los fósiles más conocidos de la actualidad, ya que sus restos a menudo se pueden observar incrustados en paredes rocosas, escaleras y pisos. Esta antigua criatura sirvió como fuente de inspiración para el diseño futurista de la Trilobite.

Important Safeguards

When using an electric appliance, basic precautions should always be followed, including the following:

Trilobite is a machine that moves by itself. It is tempting to prying children´s fingers and is at work when nobody is around… With this in mind, it is important to read all instructions before you put it to work.

Danger Warning Precaution

To reduce the risk of fire, electric shock or injury:

General

Use

Only use Trilobite for normal household vacuuming, as described in this manual.

• Use only the charger provided to recharge Electrolux Model ZAC100

• DO NOT MUTILATE OR INCINERATE BATTERIES, AS THEY WILL EXPLODE AT HIGH TEMPERATURES

Do not use Trilobite to vacuum

• outdoors

• attics, unfinished basements or garages

• bathrooms, washing rooms or other wet rooms

• ventilation rooms, inside false ceilings etc.

• staircases

• tabletops, shelves etc.

• warehouses, industrial buildings etc.

Attention

Liquids: Do not allow Trilobite to vacuum liquids, since this

may severely damage the machine. Very thin dust: Do not allow Trilobite to vacuum very thin dust such as cement or plaster, since this may severely damage the machine.

Children

Do not allow Trilobite to be used as a toy. Do not leave children alone with Trilobite. Children are curious and Trilobite is exciting. If a child by mistake starts the machine, he/she could become frightened and run away, risking injury.

Magnetic strips

Do not install magnetic strips close to magnetic objects, since the magnetic fields generated by them may affect the function of the strips. Move magnetic objects to another place in the room.

Carpet wear

In exceptional cases,Trilobite´s brush roller may cause certain types of carpet to wear quickly.

Risk of personal injury

• This vacuum cleaner creates suction. Keep hair, loose clothing, fingers and all body parts away from openings and moving parts.

• Do not use without a filter in place. When servicing the unit, never put fingers or other objects into the fan chamber in case the unit should accidentally be turned on.

• Leaks from battery cells can occur under extreme usage or temperature conditions. If the liquid gets on the skin, (1) wash the area quickly with soap and water or (2) neutralize it with a mild acid such as lemon juice or vinegar. If the liquid gets into the eyes, flush them immediately with clean water for a minimum of 10 minutes. Seek medical attention.

• When Trilobite is working, somebody could stumble over it. This is especially possible when Trilobite is returning to the charger – when it’s quiet as a whisper.With this in mind, make sure everyone in your home knows that Trilobite is working.

• Do NOT sit or stand on Trilobite!

2 English

Cleaning the dust and filter collector

Carefully empty the dust collector. Dust collected in the unit can cause allergic reactions in sensitive persons. (Use only original Electrolux micro filters for a snug fit.)

Be especially careful if there is a chance Trilobite has vacuumed rat poison, detergent, disease carriers etc.

Please be aware that Trilobite may have vacuumed up insects or spiders.

Risk of falling

The Trilobite cannot sense differences in surface level of less than 4 inches. Consequently, it might travel down a stairway or fall off a terrace or balcony if the initial difference is small. It may even start climbing up gentle inclines such as a children’s-room slide. Be sure to close all doors and “box” Trilobite in with magnetic strips where necessary. (Strips are available as post-sale items.)

• Do not place any objects on the top step.

• Do not use on stairs

Loose objects on tables etc.

Trilobite automatically stops _ inches in front of objects such as chairs, tables and pedestals. Make absolutely sure that Trilobite cannot vacuum over suspended or dangling items such as electric cords, tablecloths, belts or drapery cords. In the worst case,Trilobite will pull objects off tables and cabinets or down from your walls.

Objects on the floor

Pick up small objects on the floor that might be vacuumed by Trilobite.

Combustibles, risk of fire

Never use Trilobite to:

• Vacuum rooms with an open flame such as a lit candle, kerosene or oil lamp.

• Vacuum rooms with a working open fireplace without supervision.

• Vacuum rooms where curtains or other textiles can come in contact with

a source of ignition.

• Vacuum up flammable or combustible liquids such as gasoline or use in areas where they may be present.

• Vacuum up anything burning or smoking, such as cigarettes, matches or hot ashes.

• The terminal on the vacuum cleaner should be kept clean and free of obstruction.While there is no shock hazard from the terminal, a burn could occur if a metal object is inserted into the terminal area.

Because Trilobite can build up static electricity, never use it in rooms where the air contains:

• Combustible vapors from gasoline, kerosene, paint thinner etc.

• Aerosol fumes from hairsprays or deodorants.

Do not spray Trilobite with fragrances when it is operating.

Risk of electric shock

• Do not operate either Trilobite or its charger if either has been damaged in any way.

• Do not pull or carry the charger by its cord, use the cord as a handle, close a door on the cord or pull it around sharp edges or corners. Keep the cord away from heated surfaces.

• Do not unplug the charger by pulling on its cord.To unplug the charger, grasp and pull its plug.

• Do not handle either Trilobite or its charger with wet hands.

• Store indoors in a cool, dry area to avoid electrical shock and/or cleaner damage.

If Trilobite is not working properly, has been dropped, damaged, left outdoors or dropped into water, take it to a service center.

Trilobite

Trilobite navigates using ultrasound and uses infrared light to detect differences in surface level. During Wall Mapping, it receives information about the size of the room.Wall Mapping is the basis for the estimated duration for independent vacuuming in Normal vacuuming mode.

NOTE:Trilobite is not fully charged upon delivery. Before using it the first time, connect it to the battery charger (see page 7). A full battery charge takes approximately two hours.

Battery charger

Put the battery charger on the floor, plug it into a nearby outlet and place it with its rear side facing the wall.Allow a free space of 8 inches on the right side of the charger.When Trilobite has completed Normal vacuuming, it returns to the charger.The batteries are then charged, and it is ready for more work.

Magnetic strips

The magnetic strips serve as “virtual walls” and are important for correct operation. Use them to block door and wall openings, as well as differences in level of less than 4 inches (see page 8).

Be sure to block differences in level of less than 4 inches with the magnetic strips. If you fail to do so, Trilobite could fall over the edge and cause injuries or damage to property.

A self-adhesive magnetic strip that has been pulled back up has less adhesive capability.We therefore strongly recommend that you permanently mount all necessary strips. Never re-use the adhesive of a magnetic strip in any application where safety is important. Note that the magnetic strip is not a safety device unless it is fastened to the floor; that applies to both the selfadhesive and the wider strip. If you nonetheless choose to let a strip lie unfastened on the floor, make sure that the side with the adhesive (covered by the protective paper backing) is face down! For the wide magnetic strip, the flat side (marked with two parallel grooves) should be facing downwards.

Use a pair of scissors or a knife to trim magnetic strips to the correct length. See page 8 in the user instructions to see how a magnetic strip should be fitted.

NOTE: Magnetic strips left partially coiled, may attract Trilobite when it is seeking the battery charger – uncoil the magnetic strip completely.

Emptying the dust collector

Empty the dust collector when the Dust Collector icon shows in the display. Be sure to empty the dust collector, even if it is not completely full.The light indicator may be displayed if a filter is blocked.

Vacuuming program

Trilobite has three vacuuming programs: “Normal” Trilobite first plots the room by following the walls

(wall mapping) and then vacuums all open surfaces. “Quick” The same as Normal but without Wall Mapping. “Spot” Trilobite vacuums an area of about 10 sq.ft. twice.

See page 10 for more information on how to proceed and when to use the different programs.

Starting vacuuming

You will probably use the Normal program most of the time. This program starts with Trilobite approaching a wall and then mapping the walls by left turns.Trilobite makes one full circuit of the room, continually turning left. Depending on the size and layout of the room, wall mapping may take up to 15 minutes (25 minutes, if Trilobite has found the charger).Wall Mapping ends when the circuit is complete, and vacuuming commences.

Main cleaning program

During the main cleaning sequence,Trilobite moves freely all over the room.Trilobite “sees” its way around with the help of harmless ultrasound.This is the same technique that bats use to navigate in the dark, for instance, and for fetal diagnostics in

hospitals.When it discovers an object in its path,Trilobite stops a couple of inches in front of it and then changes direction.

Trilobite can handle most obstacles. However, if it does get stuck,Trilobite will continue with its cleaning program if you release it within 20 minutes, put it back down on the floor within 30 seconds and press the “Yes” button.

Charging

If Trilobite is started from the charger unit or locates it during Wall Mapping, it will return to the charger whenever the battery falls below a specific charge level. If there is not enough battery power to finish the cleaning cycle,Trilobite will go to the charger and park for charging.While charging to resume cleaning, Trilobite will give an audible signal at regular intervals. Charging can be stopped by pulling Trilobite away from the charger and pressing the On/Off button.Trilobite can then be put back in the charger and will resume charging without the signal.To start cleaning again, start Trilobite manually.

When the job is done,Trilobite returns to the charger. If Trilobite cannot find the charger during Wall Mapping and the battery voltage becomes too low, it will stop somewhere in the room.

Getting started

To make it easier to find the charger, start Trilobite towards a wall close to the charger.

Charger

Place the charger close to a wall.

This way, Trilobite will find the

charger during Wall Mapping.

Start

Start Trilobite directly from the charger, or face it towards a wall at a distance of 20 inches. Start vacuuming (see page 10).

Wall mapping

Trilobite starts by travelling along the walls of the room to establish the size of the room.

Cleaning

During the Vacuum Cycle, Trilobite moves through the room on its own.

NOTE: Trilobite starts by first travelling along the walls to establish the size of the room. If the charger is placed at an isolated item in the room (e.g. an island), Trilobite will not be able to find its way back to the charger.

English 7

You may well develop a personal affection to Trilobite and appreciate its intelligence.To get the best from your Trilobite, we recommend you consider the following.

Charging (also see the picture “Charging status”)

Check the battery indicator before vacuuming starts. Refer to the lower, middle picture.

A.Charge your Trilobite before vacuuming. B.You can start vacuuming, but your Trilobite will need to find the

charger soon.

C.You do not need a charger in the room to start vacuuming.

Avoid interrupting the charging process. If unavoidable, pull Trilobite away from its charger and press the On/Off button. Vacuuming can also be started while Trilobite is still being charged. If the power to the charger is interrupted for more than 30 seconds during charging and you have not manually placed Trilobite in the charger, it will leave it, take a spin on the floor and then connect with the charger again.

Move the furniture

Trilobite picks its way around furniture, whether standing free or flush against a wall. However, cleaning is both quicker and more effective if you move the furniture slightly before it is time to start cleaning. Of course, you do not need to move heavy furniture such as sofas, but chairs can be placed on top of tables, floor lamps can be moved out of the way and loose rugs can be shifted. But don’t complicate matters more than you need to! Normally, all you have to do is to put Trilobite on the floor and let it get on with the job of cleaning.

Loose objects

Trilobite cannot distinguish between dust, coins, rings and expensive jewelry. Before starting Trilobite, be sure to put away small, loose objects you do not want to lose.

Also make sure there are no cords or other objects on the floor

that may prevent Trilobite from moving freely around the room.

Important safeguard

Before vacuuming, read “Important safeguard” on pages 1–2!

ABC

Preparations Before Use

Recharging

Push the Trilobite unit with its rear against the battery charger’s contact plate. Press it in securely. Keep it pressed in until you hear an acknowledging signal (this may take a few seconds). This is particularly important if the batteries are entirely – or almost entirely – dead.

The battery charger should be placed along a wall with a free margin of 8 inches to the right of the charger.

Charging status

The battery indicator on Trilobite’s display shows the battery capacity during vacuuming and charging.

An audible signal sounds and the battery symbol in the display shows when charging commences. Trilobite becomes fully charged in about two hours at which time “Ready” shows in the display.

If the battery charger is placed on a soft surface like a loose rug or fitted carpet, or if there is protruding ledge which does not allow the battery charger to be placed snugly against the wall, use the adjustable screws located on the rear of the unit to rectify this.

Rooms with a staircase

Trilobite can detect staircases with a step height of 4 inches or more.When Trilobite detects such a staircase, it stops automatically. Do not place any objects on the top step.

Rooms on different levels or with inclines.

Trilobite can not detect differences in surface level of less than 4 inches. If a room has such a difference in level – and especially if it leads to a stairway – it should be blocked with a magnetic strip to ensure the unit stops before reaching the obstacle.

Rooms with wall openings

Trilobite is able to vacuum rooms with wall openings or walls placed at odd angles. However, this will take longer than usual. It is a good idea to vacuum one room at a time and separate the rooms by using a moveable magnetic strip as shown above. To prevent Trilobite from pushing the moveable magnetic strip, the support at each end should be minimum 2 inches. Always move the magnetic strip to the room where Trilobite is in operation.

Rooms with thresholds

Always fit the magnetic strip on the floor in front of the threshold in the room you will be vacuuming. See Figures 1 and 2.

Magnetic strips and carpets

If the carpet has a pile depth of less than 3/4 of an inch, the magnetic strip can be placed under it with maintained functionality. If the strip is fitted on top of the carpet, be sure it is securely attached.

Be careful!

Before starting Trilobite, be sure to put away small, loose objects that might otherwise be vacuumed by Trilobite.

Also make sure there are no cords or other objects on the floor

that may prevent Trilobite from moving freely around the room.

NOTE! Do not place the magnetic strip at an angle of less than 90°.

Questions and Answers

Should I pay attention to anything special when I vacuum a room for the first time?

It is a good idea to be present when the room is vacuumed the first time, for example to see if it takes unnecessary time for Trilobite to navigate around furniture.

Can I use Trilobite in a room with an activated alarm?

Yes, if it has a “pets monitoring” function.

Can I hide the magnetic strips under, say, a carpet?

Yes, as long as it is not thicker than 3/4 of an inch.

What’s the purpose of the audible signals?

They confirm that a command or measure has been correctly received or to advise of a problem.

Trilobite operates at different speeds. Is something wrong?

Not at all. The speed varies, depending on the layout and furniture in the room.

Is it okay to leave Trilobite connected to the charger whenever it isn’t in use?

Yes, but make sure children cannot start it by mistake.

Is it necessary to switch off Trilobite before charging it?

No.

How can I know if I’ve positioned Trilobite correctly for manual battery charging?

A battery symbol lights in the display and you hear an audible signal.

Why doesn’t it charge?

1. Check that Trilobite is correctly connected to the charger (see the question above).

2. Check that the charger has been plugged into an outlet.

3. Check that the rear of the charger has enough support (see page 7).

Is it dangerous to touch the charging terminals?

No. They have no power in output mode and carry max. 28 V in input mode.

Why does Trilobite sometime pause for approximately 10 seconds during vacuuming?

Trilobite uses two battery packs. It will briefly pause when switching from one battery pack to the other.

Why does Trilobite stop completely during vacuuming?

1. Check that it has been sufficiently charged (see page 7).

2. Did it find the charger during wall mapping?

3. The time duration for vacuuming may need to be increased (see page 11).

Why does Trilobite crackle while vacuuming?

This sound is produced by the navigation system.

Why do I need to replace the filter so often?

The filter is actually one of the most important components in the machine. It collects all dust, even very small dust particles (this is why you should also use original Electrolux filters). Just as a dust bag becomes full, so does the filter. Trilobite needs no dust bag, but the filter is always necessary.

If Trilobite starts to smell bad, what could be causing it?

The dust filter was probably not replaced.

What should I do when an error message is displayed?

The errors you yourself can correct are shown on page 11. In all other cases, contact Customer Service (see page 16).

What’s the Cable Protection System?

This is simply a system that prevents Trilobite from getting stuck in electric cords on the floor.

What’s the Trilobite Stairsafe system?

It is a safety system that uses infrared light to help Trilobite detect and avoid staircases .

Do I also need to vacuum manually?

Sometimes this may be necessary in corners or along the walls in the room.

In one room,Trilobite does not start and error code 12 is displayed.

On some extremely dark or shiny floors, Trilobite will not operate. This could also be the explanation if Trilobite will not go out on a surface or into a room.
