Knowing The Control Panel
Smart Features
No matter which modes are chosen, these smart features are included into the software:
• Upside-down: The Volt 550Li is fully capable of detecting when it is upside-down and can then reorient
itself to continue cleaning. It also has a feature where, if it cannot ip itself over (such as if it is stuck on
an obstacle or too full of heavy debris), it will shut itself OFF to avoid wasting energy from the batteries.
When this happens, you can ip over your Volt 550Li and it will start cleaning again.
• Out of water: The Volt 550Li can detect when it is in or out of water and will avoid wasting energy when
it is out of the water. It will also drive itself back into the water, which is especially useful for beach style
pools or pools with steps. If the Volt 550Li is out of water for too long, it will shut itself down (with the
LEDs still ON). To continue operation you must turn it OFF and ON again.
• Cleaning Path: The Volt 550Li is programmed with a completely unique cleaning path that will t any
non-commercial size, shape, and style of pool.
*Note: When your Volt 550Li is in sleep mode, only the Battery LEDs (and ON/OFF LED for
“Weekly” Mode) will stay ON.

7
a. Select Cleaning Cycle
1-Day Cleaning Cycle
• 1-Day: The Volt 550Li will run continuously for up to
2 hours and then go into sleep mode. If 2 hours is not
enough, you can wake the robot from the sleep mode
to start another 2-hour cycle. The robot can run for
two “1-Day” cycles on a single charge. This mode is
most e󰀨ective for thorough cleaning of a dirty pool.
Weekly Cleaning Cycle
• In “1-Day” Sleep mode the ON/OFF LED is o󰀨 and both
battery LEDs stay on. The robot will not wake from this
“Sleep” mode until you turn the robot OFF and ON (or
press the “Cleaning Cycle” button). It is recommended
to turn the robot OFF if you do not intend on using it
again immediately.
Sleeping during 1-Day
Cleaning Cycle
Sleeping during Weekly
Cleaning Cycle • When in Weekly Sleep mode, both Cleaning Mode and
Cleaning Cycle LEDs will turn o󰀨. Only the ON/OFF LED
and the battery LEDs will stay on for the entire time that
the robot is in sleep mode. You can leave the Volt 500Li
in your pool while it’s in sleep mode. If you take your
Volt 550Li out of the pool, make sure you place it facing
the pool so it can drive itself back in when it wakes up.
You can program the Volt 550Li to run continuously or in intervals over a week long period.
• Weekly: The Volt 550Li will run on a schedule (illustrated
on next page) that will end after 7 days, at which point
the battery will be fully discharged. This mode is most
e󰀨ective for maintaining a clean pool as it will clean the
debris that slowly accumulates throughout the week.

8
b. Select Cleaning Mode
• Cleaning Modes: The Volt 550Li is equipped with tilt sensors to help achieve the customer’s
desired cleaning mode.
• Floor & Walls – The Volt 550Li will clean
the oors and climb the walls, enabling
the Volt 550Li to scrub the waterline.
Floor & Walls Mode
• Floor Only – The Volt 550Li will stay on
the oor, picking up debris and scrubbing
scum. It will partially climb the walls
enough for it to clean the hard to reach
edges along the bottom of some pools.
Floor Only Mode
Weekly Cycle Running Schedule
Weekly cycle runs your robot every day for a full week. Starting from when you rst turn it
on, the robot will clean approximately 60 minutes. Then at the same time every day for the
remainder of the week, the robot will run for approximately 30 minutes.

9
a. Charging your cleaner
CHARGING TIME: 6-8 HOURS
Be sure to charge in a dry shaded area.
(The Volt 550Li will not run when the charger is plugged in).
The robot cannot be charged while in the pool. But the robot can be charged immediately after removing from the
pool. Just make sure that the pins of the robot’s charging jack are dry before plugging in the charger.
DO NOT charge outside of the accepted temperature range: 41 to 113°F (5 to 45°C)
DO NOT use extension cord or power strip.
DO NOT expose charger to water or direct sunlight.
DO NOT leave unit plugged into charger for extended periods of time.
DO NOT leave unit plugged into charger during long term storage.
ONLY USE the charger that came with the unit.
Prepare the Cleaner for Use
• End #1: To unit’s charging jack.
• End #2: To an Indoor Grounded
Residential power source.
Make sure there is no water present on
the pins of the Unit’s charging jack.

Battery Packs Charging (Flashing) Battery Packs Charged (Solid)
If one or both LEDs are not ashing or do not turn solid, contact Water Tech Customer Service.
As both battery packs are charging,
the LEDs (shown above) will ash.
Once a battery pack is fully charged, its
LED will turn solid. It is common for 1 LED to
turn solid before the other.
If the Volt 550Li is charging with the Power (ON/OFF)
Button turned ON, the “1-Day”, “Weekly”, and “ON/
OFF” LEDs will be ON (as shown on the left). The
Volt 550Li will not be able to operate until the Power
(ON/OFF) Button is turned OFF and then back ON.
If you notice these LEDs are ON during charging, it
is recommended that you turn the Power (ON/OFF)
Button OFF.
*This is a safety feature to ensure that the Volt 550Li
does not turn itself ON while charging or shortly after
unplugging the charger.

b. Filter Bag mounting
Closed Cover Unlocked Cover
Filter Bag & Cover (Out) Filter Bag
To remove the Filter Bag, ip the
Volt 550Li upside-down and turn the knob
on the bottom counter-clockwise.
You will feel the knob “snap” as the lock
is undone. Note that the locks will move
inwards. This means the cover
is unlocked.
Pull out the entire bottom cover. The lter
bag will be locked by the locking tabs
inside the cover (Illustrated above as #1
and #2). To remove the lter bag, carefully
push the lter bag out of the locking tabs.

you lower the cover into place.
Turn the knob clock-wise to lock the
cover. You will hear a “snap” again as the
cover locks.
The locking tabs will move outwards.
This means the cover is locked.

13
Start Cleaning
Aim at the pool
Aim the Volt 550Li at the pool (place robot
roughly 3 ft. from the edge of the pool).
For above ground pools, drop the robot in the pool after
selecting your desired settings
Push the ON/OFF button and select your
desired Cleaning Cycle and Cleaning Mode.
When the Volt 550Li is done charging, it’s
important that you DO NOT submerge the
Volt 550Li in water without replacing the
rubber plug covering the charging jack.
Failure to follow this step could damage
your unit.
(After the robot is turned on, you will have 10 seconds to
select your desired Cleaning Mode and Cleaning Cycle
shown on Page 7-8)

14
Retrieval After Use
Rest the Volt 550Li on the edge of the pool to allow water to drain
from the drain valve. Turn the power switch OFF when removing from
pool, even if the batteries are fully discharged.
Cleaner can stay in the pool for up
to 7 continuous days, even with
the battery fully drained.
Lift the Volt 550Li to the surface using a slow, steady pulling
motion. Remember, the Volt 550Li is heavy while full of water.
