EL520A Trilobite Robotic Vacuum
Imagine
pushing a button, walking away, and having clean floors an hour
later. That futuristic scenario is now here with the Trilobite, the
hands-free, "intelligent" robotic vacuum first introduced
in Europe by Electrolux. While it isn't the first robotic home
vacuum, the Trilobite is a major leap in home robotic technology -
one that is reflected in its price. Where other small, round
semi-autonomous vacuums are essentially "dumb" robots that
randomly move about a room, the Trilobite uses a type of radar that
maps a room and then plots a course based on previous cleaning
travels.
The round Trilobite uses ultrasound technology
to see obstacles and avoid them. The Trilobite
Robotic Vacuum pings 60,000 Hz
ultrasound vibrations at surfaces to create a map of the room and
remember it for future assignments. This computer processing power is
what raises the Trilobite's profile over the competition, whose
vacuuming robots can only react to a situation (such as bumping into
something) and cannot store data into memory.
Product Features:
Robotic vacuum cleans hard floors and carpet
without supervision
Bright red color; 3 cleaning modes; reusable
dust box; LCD display
90 watts; vacuums for approximately 60 minutes
on 1 charge
Automatically returns to charging station,
recharges, then resumes cleaning
Measures 14 by 5 inches, weighs 11 pounds;
includes 2 internal battery packs
Start the Trilobite by simply pressing the
power button and answering yes to the question, "Start
cleaning?" that appears on its LCD screen. The Trilobite then
moves to the nearest wall, following along the edges of the room to
create an inner picture of the room. This wall phase (the Normal mode
of operation) forms the basis for calculation of the time required
for cleaning of the open spaces that follows. The sonar detects any
obstacles and a new path is quickly calculated. Transition between
hard floors and carpet takes place effortlessly.
The Trilobite
also offers two additional operation modes. The Quick mode, which is
good for a small room or last-minute tidying before the in-laws
arrive, skips the wall measurement and moves about the room randomly
for around 20 minutes. If you've just dumped a bag of flour on the
floor or the kids have tracked an inordinate amount of dirt in from
the backyard, the Spot mode can concentrate on an area about 3 feet
(1 meter) square, covering every part in a maze-like pattern. You can
also choose to clean via a timer for up to 60 minutes.
The Electrolux
EL520A Trilobite Robotic Vacuum carries two environmentally
friendly nickel-metal hydride batteries (NiMH) batteries on board,
switching to the second as the first runs low on energy. As the
second battery's power dips below the 50% point, the unit will cease
vacuuming, return to its docking station, charge for about two hours,
and return to the point where it ceased vacuuming to complete the
task. The recharging dock fits along the base of any wall within 6
feet of a power outlet.
