Knowing The Control Panel
On the next page, you will nd more detail on how each mode and cycle works.
*Note: When your CX-1 is in sleep mode, only the Battery LEDs (and ON/OFF LED for “Weekly”
Mode) will stay ON.
No matter which modes are chosen, these smart features are included into the software:
• Upside-down: The CX-1 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 CX-1 and it will start cleaning again.
• Out of water: The CX-1 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 CX-1 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 CX-1 is programmed with a completely unique cleaning path that will t any non-
commercial size, shape, and style of pool.
Smart Features

7
You can program the CX-1 to run continuously or in intervals over a week long period.
a. Select Cleaning Cycle
1-Day Cleaning Cycle
• 1-Day: The CX-1 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
CX-1 in your pool while it’s in sleep mode. If you take
your CX-1 out of the pool, make sure you place it facing
the pool so it can drive itself back in when it wakes up.
• Weekly: The CX-1 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.

Floor Only Mode
8
b. Select Cleaning Mode
• Cleaning Modes: The CX-1 is equipped with tilt sensors to help achieve the customer’s
desired cleaning mode.
• Floor & Walls – The CX-1 will clean the
oors and climb the walls, enabling the
CX-1 to scrub the waterline.
Floor & Walls Mode
• Floor Only – The CX-1 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.
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.
Weekly Cycle Running Schedule

Prepare the Cleaner for Use
a. Charging your cleaner
• 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.
CHARGING TIME: 6-8 HOURS
Be sure to charge in a dry, shaded area.
1.
2.
(The CX-1 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.
Charger Unit’s Charging Jack
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.

10
If the CX-1 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
CX-1 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 CX-1 does not
turn itself ON while charging or shortly after unplugging
the charger.
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.

11
Prepare the Cleaner for Use
b. Filter Bag mounting
Closed Cover Unlocked Cover
Filter Bag & Cover (Out) Filter Bag
To remove the Filter Bag, ip the CX-1
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.
Remove the bag and rinse out with a
hose or in a sink.

12
Filter Bag & Cover (In) Lock Cover
Closed Cover
Re-insert the lter bag with the cover on
top. Make sure you lock the bag under
the two locking tabs (Illustrated above as
#1 and #2). Then, insert bag into unit as
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 CX-1 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 CX-1 is done charging, it’s
important that you DO NOT submerge the
CX-1 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 CX-1 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 CX-1 to the surface using a slow, steady pulling
motion. Remember, the CX-1 is heavy while full of water.
Warning! Risk of Drowning!
