Robot Vacuum Not Detecting Carpet? Check Boost and Sensors

The eufy E25 and E28 article covers BoostIQ and Carpet Cleaning Mode. Samsung’s Australian BESPOKE Jet Bot AI+ page covers suction levels, the Roborock S7 manual describes VibraRise carpet handling, and ECOVACS FAQ 119 covers Auto-Boost Suction on DEEBOT. As a precaution, match your robot to the models or product line listed in the table before changing a setting. Each row links to its source.

Direct answer: match the carpet symptom to your model

For eufy E25 and E28 carpet detection problems, check BoostIQ and Carpet Cleaning Mode, then inspect the ultrasonic sensor as eufy directs. On the Australian Samsung BESPOKE Jet Bot AI+, carpet-triggered suction increases require Smart suction power. As a precaution, change one setting at a time and test on the same carpet, so you can see which change had an effect. The sources below cover four brands: Roborock, ECOVACS, eufy and Samsung.

Carpet settings by brand

What changes by model

The table summarizes each brand. The sections below give the wording of each source.

Roborock

The Roborock S7 manual, a PDF, lists Carpet Boost among its More App Functions. Its VibraRise section says: “If the VibraRise mop cloth mount is attached, the robot will lift the mount to clean carpeted areas. You can choose to avoid carpeted areas in the app.” The same manual says: “By default, No-Mop Zones will activate when the VibraRise mop cloth mount is in place.” Its error list includes “Error 28: Robot on carpet. Move robot to floor and retry.” and “Cannot cross carpet. Move robot across carpet and restart.” Its list also includes “Error 27: VibraRise system jammed. Check for obstructions.”, which concerns the same mount.

ECOVACS

ECOVACS FAQ 119, updated on July 14, 2020, explains Auto-Boost Suction on DEEBOT. It says to turn on Auto-Boost Suction under More in the app, after which strong suction is enabled automatically on carpet. The FAQ says the feature is not supported while the suction inlet is used for cleaning, and it recommends turning it on only for homes with carpet floors. It also warns that strong suction can be enabled accidentally on non-carpet floors when hair tangles around the main brush, and advises cleaning the main brush regularly.

As a precaution, check that the feature appears under More in your app before following the FAQ’s steps, because the FAQ is dated 2020.

eufy

The eufy article for the Omni E25 (T2353) and Omni E28 (T2352) covers carpets that are not detected during cleaning. It says to check that BoostIQ is enabled in the app and to review the selected Carpet Cleaning Mode. It then says to inspect the ultrasonic sensor for dirt or debris, and to clean it gently with a soft cloth or cotton swab. If the problem continues, it asks you to contact eufy with your account details and the date and time of the cleaning session, with Activity Log Upload enabled. The article links to a separate support article with full instructions for that step. For carpet zones missing from the map, the article says zones are updated only upon task completion, and asks you not to pick up or move the robot during a cleaning session.

The eufy S1 Pro article addresses incorrect carpet detection that makes the roller mop rise on non-carpeted floors. It lists firmware V6.9.79 as a solution. Another solution combines Normal Cleaning under Carpet Cleaning Settings for the whole house with marking every carpeted area as a No-Mop Zone.

Samsung

Samsung’s Australian page for the BESPOKE Jet Bot AI+ says suction power can be set to Max, Smart or Normal. It says that when the Jet Bot detects carpet during cleaning, it increases its suction power. The Intelligent Power Control Clean feature, along with Corner Clean, works in Smart suction power only.

As a precaution, confirm the suction setting on your own app before following these steps, since the page describes the Australian product.

Check the sensor and the carpet itself

The Roborock S7 manual lists the carpet sensor in its monthly maintenance table, with the instruction “Wipe clean with a soft dry cloth.” Its sensor section says to use a soft dry cloth to wipe and clean all sensors, including the carpet sensor. For the eufy E25 and E28, use the ultrasonic sensor steps above. For the ECOVACS DEEBOT, keep hair off the main brush, as FAQ 119 advises.

The S7 manual also says: “Do not use the product on high pile carpets (product effectiveness may also be reduced on dark carpets).” Follow that limit when choosing where the S7 runs.

The S7 manual requires switching off the product and unplugging it before cleaning or maintenance. As a precaution, follow your model’s shutdown instructions and wait for all movement to stop before wiping a sensor. For cliff and bumper sensors on other robots, see the robot vacuum sensor error guide.

Carpet avoidance and No-Mop Zones

On the Roborock S7, the VibraRise mount lifts for carpet, and carpet avoidance can be selected in the app. Its manual says No-Mop Zones activate by default when the mount is in place. For an eufy S1 Pro roller mop that rises on non-carpeted floors, one documented solution combines Normal Cleaning for the whole house with marking every carpeted area as a No-Mop Zone. As a precaution, apply one of the listed solutions at a time and check the mop after each change. For mop pad fit or wear, see the robot mop pad guide. For map problems beyond the E25/E28 carpet-zone checks above, see the mapping problems guide.

When to contact support

For the eufy E25 and E28, the article asks for your account details and the date and time of the cleaning session, with Activity Log Upload enabled. The S1 Pro article directs you to eufy support for further help. For the Roborock S7, the manual lists error texts such as Error 28. As a precaution, write down the error text shown in the app and the type of carpet before you contact the manufacturer. As a precaution, record the model name and firmware version shown in the app as well.
