Using Your RoboVac 

Important Tips Before Use

1. Remove power cords and small objects from the floor that may entangle RoboVac.
2. Fold tasseled edges of area rugs underneath to prevent tangling RoboVac. Avoid cleaning very dark-colored high-pile rugs or rugs thicker than 1.02 in/26 mm as they may cause RoboVac to malfunction.
3. Keep RoboVac away from spaces lower than 2.87 in/73 mm to prevent RoboVac from getting stuck. If necessary, place a physical barrier to block off the problem areas.
4. Keep RoboVac away from wet areas.
5. RoboVac may climb on top of objects less than 0.63 in/16 mm in height. Remove these objects if possible.
6. Anti-drop sensors prevent RoboVac from tumbling down stairs and steep drops. They may work less effectively if dirty or used on reflective/very dark-colored floors. It is recommended to place physical barriers to block off areas where RoboVac may fall.

TIP: Place physical barriers in front of fireplaces and areas that may cause damage to RoboVac if entered.

Preparation

1. Install the side brushes before use.

2. Turn on the main power switch on the bottom of RoboVac.
   TIP: Remove the sticker next to the power switch, and the foam blocks beside the bumper before use.

   

3. Place the Charging Base on a hard, level surface and against a wall.

   

4. Remove objects within 3 ft/1 m of the left and right side and within 6 ft/2 m of the front of the charging base.

5. Connect the round connector of the adapter into the power socket on the Charging Base and the other end into a wall outlet.

   

   When the Charging Base connects to AC power, the LED indicator on the Charging Base is SOLID WHITE.
   TIP: Install the Charging Base in a location that RoboVac can easily access. It is recommended to place the Charging Base against a wall, and on a hard-level surface rather than on rugs or carpets.
   Always keep the Charging Base plugged in, otherwise RoboVac will not automatically return to it.

Charge Your RoboVac

• RoboVac has a pre-installed rechargeable battery that has to be fully charged before use.
• RoboVac returns to the Charging Base at the end of a cleaning cycle or when its battery is running low.

Method 1: Attach RoboVac to the Charging Base by aligning its charging pins with the charging pins on the base.  

Method 2: Press  on the remote control to return RoboVac to the Charging Base. 

TIP: Turn off the main power switch if RoboVac will not be used for a long period of time. To preserve the battery’s lifespan, recharge at least once every 6 months.

Select a Cleaning Mode

Auto cleaning 

RoboVac optimizes its cleaning path by selecting different cleaning modes automatically until cleaning is complete. This is the most commonly used cleaning mode.

Press on RoboVac or on the remote control to start cleaning in Auto Mode. 

TIP

• RoboVac will return to the Charging Base automatically when the battery level becomes low or when RoboVac finishes cleaning.
• By default, RoboVac starts in Auto cleaning mode when it is turned on.

BoostIQ Feature 

When the BoostIQ feature is enabled, RoboVac will automatically increase the suction power if it detects stronger power is needed to ensure the best clean. BoostIQ™ is ideal for cleaning thicker carpets and hard-to-sweep messes, which will reduce the total cleaning time, but increase the noise level. If the vacuuming noise caused by BoostIQ™ disturbs you, you can disable this feature. This feature only works in Auto and Single Room cleaning modes.
In Auto or Single Room cleaning mode, press on the remote control repeatedly to adjust the suction power level. 

The corresponding icon is displayed on the remote control.

TIP: When RoboVac starts cleaning in Auto or Single Room mode the next time, it will clean according to the suction power level you previously selected.

Spot cleaning 

RoboVac intensively cleans a specific area in a spiral pattern, useful if there is a concentrated area of dust or debris. In Spot mode, RoboVac will stop cleaning after 2 minutes.

Edge cleaning

RoboVac reduces its speed when it detects a wall and then follows the wall to ensure the edge is cleaned thoroughly. In Edge mode, RoboVac will clean for 20 minutes and return to the Charging Base.
Press on the remote control to start cleaning in Edge mode.

Quick cleaning

RoboVac will automatically stop cleaning after 30 minutes and return to the Charging Base in this mode. If any small room or area needs to be cleaned, it is recommended to select this mode to save time and power.
