  • What do I do if the entire house is still not mapped after several runs or if I have a two-story house?
    To add another room or level of your home, manually place the robot in the new unmapped territory. The robot will recognize it has not mapped the space and adds it to a new map.
  • Can I use the App on my mobile device as a remote control?
    Yes, go to the More Controls menu located at the upper right corner of the Home Screen. Select Remote Control Mode. Use your fingertip to control up, down, left, and right directions, and Play/Pause. Return to Home Screen.
  • Why does the map change colors on the app screen after initial use?
    After scanning an entire room for the first time, the map will appear in blue. After a few more initial runs, the map will show separate rooms and turn orange. After sweeping the edges of walls and creating the “Z” path marks, the map will show different shades of colors to help customize Room or Zone Cleaning.
  • How do I know my Dirt Devil Clean app is the latest version
    Go to “Firmware Update” in More Controls.If the text does not state it is the current version, click on Detect New Version for automatic updates.

    In the More Controls menu in the upper right on the Home Screen, select Robot Settings. Then select the Do Not Disturb Mode. The robot will not resume or perform any unfinished cleaning and will not broadcast audio alerts when DND is activated.
  • Can I use Mapping and Setting Zones from the first time I use the robot?
    Your Dirt Devil Robot needs to learn the layout of your home and it may take more than one auto-cleaning run to fully map it. Depending on the size of your house, it could take 5-6 mapping runs or more.
  • How do I create Zones and No-Go Zones?
    Tap the Map Settings in the lower right of the Home Screen, then No-Go Zone. Use the square or line icons to define areas accordingly. Tap either one to overlay on any area of the current map. Use fingertips to drag and adjust size and shape or use simple lines to draw virtual boundaries.
  • How do I select a specific room to clean?
    After the robot completes the mapping process, the map will be saved automatically showing boundaries for a room or more than one room. At this point you can use Room Cleaning by swiping up on the Home Screen to reveal the option. You can also use the mapping menu for additional customization and the scheduling feature to select a specific room.
  • Does the app keep a history of cleaning schedules?
    In the More Controls menu, select Cleaning History to see a record of cleaning runs from a schedule you created or from Auto Cleaning. The robot vacuum has to complete navigation and mapping of the whole floorplan before saving a record of cleaning sessions.

  • How do I locate my robot in the house if it doesn’t return to the charging dock?
    An audio alert will sound for the first 60 seconds if the robot pauses during operation away from the dock. In the app, you can select Find Robot to activate the audio alert. In General Settings, a notice will appear in the message section indicating the robot has paused.
  • How often do I need to clean any parts of the robot?
    The dust bin and filter should be cleaned after each use after dumping debris into a garbage can. Wipe the interior of the dust bin and the crevices of the filter. It is also recommended to clean the sensors, side brush, brush guard, charging pins, and swivel wheel once per month or more often if the robot is used frequently.
  • If I live in a 2-story house, can I run two robot vacuums from the same app?
    Get to know the pattern your robot runs on initial Auto Cleaning. Pick up stray objects in its pathways, clear away items less than 3” in height, and dangling power cords. Create No-Go Zones in the app. Create barriers to tight spaces, such as barstools or chairs and narrow spaces.
  • Why does the robot return to the charging dock before it completes the job?
    During initial use, the robot needs to learn room layouts and may do shorter runs as it maps the entire home. It will always return to the dock when the battery runs low. Larger homes may need to recharge before completing every room.
  • How do I empty and clean the dustbin?
    Press the release button to remove the dustbin. Over a trash can, lift the black-hinged portion of the bin to empty the contents. Wipe the interior with a paper towel and remove and clean the filter after each use.
  • Can I use Mapping and Setting Zones from the first time I use the robot?
    Your Dirt Devil Robot needs to learn the layout of your home and it may take more than one auto-cleaning run to complete the map. Depending on the size of your house, it could take 5-6 mapping runs or more.
  • Is it normal for the robot to randomly roam a room or two and then return to its dock?
    Yes. The first few runs on a full charge need to get to know your home’s layout. It does not need to reach every square foot of a room or multiple rooms initially but will continue to build the map as it explores and scans the entire house.
  • Why does the robot miss some areas while cleaning?
    Check to see if any doors are closed or partially closed and if there are too many items or obstacles in a room. Pick up small items and re-map rooms if areas were blocked by pets or people in a previous mapping run. Allow a minimum of 20” pathways for cleaning.
  • Why does my robot have trouble crossing the threshold of one room to another?
    The sill or strip may be too high for the robot to cross over or a variance between flooring and carpeting is difficult for the robot to transition. Move the robot over it to continue cleaning.
  • What happens to the mapping process if I turn off the robot main switch during a cleaning session?
    If the robot is turned off manually during cleaning, the data will not be saved. Turn on the main switch and allow the robot to create a new map when fully charged.
  • Is it okay to turn off the main switch on the robot if I am going on vacation or do not plan to use the robot for a period of time?
    It is recommended to power off the robot when not in use for an extended period of time. For shorter periods of inactivity, the robot vacuum will automatically switch to SLEEP mode.
  • How long will the robot run on a single charge?
    This depends on the variables of suction mode and floor surface and it differs for hard flooring and carpets. On average it can run 60-90 minutes.
  • How do I do spot cleaning and not the whole house?
    Move the robot off the charging dock and place it in the area you want to spot clean. Press the power button 2X to clean an area of 5’ x 5’ (1.5M x 1.5M). When complete, the robot will automatically return to the dock.
  • What do I do if the robot stops away from the charging dock or gets stuck?
    Manually return it to the charging dock to recharge. Pick up obstacles before the next cleaning run.
  • Can I change the location of the charging dock?
    Do not change the location during an active cleaning session or the robot will not know where to return to when the battery runs low. If you relocate the charging dock, the robot will learn the new location and create a new map. You can also delete the Current Map and start a new one.
  • How often do I have to replace any parts of the robot?
    In More Settings, tap Maintenance to see the percentage of use on serviceable parts and the life expectation. In general, expect to replace the filter, side brush, and brush roller every 3-6 months.
