Question 1

my roomba i3+ evo's edge brush on the side isn't spinning at all, how do i fix it?

Accepted Answer

The Edge-Sweeping Brush can stop spinning if it's jammed with hair or debris, or if it wasn't reinstalled correctly after a cleaning. Let's get it spinning again. Flip the robot over. You'll see the yellow Edge-Sweeping Brush on the side. Use a small screwdriver to loosen the screw holding the brush in place. Don't remove it completely; just loosen it enough to free the brush. Pull the brush straight out of its housing. Remove any hair or string wrapped tightly around the ends or the central axle. Clear out any debris from the empty brush socket inside the robot. Reinsert the brush, making sure it seats fully into the gear mechanism, and then tighten the screw back down. Don't overtighten. If that didn't work: The brush itself might be worn out or broken. The Edge-Sweeping Brush has a recommended replacement frequency of every 12 months (or every 6 months if you have a pet). Contact iRobot Customer Care for a genuine replacement part. Heads up: This brush, along with the Multi-Surface Brushes, should be cleaned once a month (twice a month with a pet) to prevent this kind of jam from happening in the first place.

Question 2

do i need to unplug my roomba i3+ evo home base when i go on vacation?

Accepted Answer

You don't have to unplug the Home Base for a vacation, but you should prepare the robot itself for storage to preserve the battery. Leaving it docked and idle for weeks is not ideal. Here is the proper procedure:Remove the robot from the Home Base. Hold down the CLEAN button for 10 seconds until all lights turn off. This completely powers down the battery. Store the robot in a cool, dry place at room temperature. Whether you leave the Home Base plugged in or unplug it is a matter of personal preference. Using a surge protector for the Home Base is advisable if you live in an area prone to electrical storms. Important: If you ever need to ship the robot, you must follow these same steps to turn the battery off first, as lithium-ion batteries have strict shipping regulations.

Question 3

roomba i3+ evo filter light is on but i just cleaned it, is it broken?

Accepted Answer

The filter alert is usually triggered by the full bin sensors, not the filter itself. The sensors are dirty or the filter is installed incorrectly. Remove the bin. Open the bin door. Wipe the inner full bin sensors on the robot and the corresponding sensor on the inside of the bin door with a clean, dry cloth. Debris buildup causes false readings. Remove the filter. Tap it against a trash container to dislodge fine dust. Do not wash it. Reinsert the filter with the ridged grips facing out. An incorrectly installed filter will prevent the robot from running. Ensure the bin is completely dry if you rinsed it. Place it back in the robot until it clicks. If that didn't work: The filter may be at end of life and needs replacement. The filter should be replaced every two months (more often with pets). A heavily clogged filter will restrict airflow and trigger the sensor. Heads up: The bin is not dishwasher safe. Only rinse with warm water, and always let it dry fully before reassembly to prevent mold and sensor errors.

Question 4

how do i get my roomba i3+ evo to stop trying to go down the stairs? it keeps bumping the edge.

Accepted Answer

Your Roomba i3+ Evo's cliff sensors are detecting a drop, causing it to bump the edge. First, ensure the Home Base is placed at least 4 feet (1.2 meters) away from the stairs to prevent falls during departure and return. Clean the four cliff sensors on the bottom of the robot with a clean, dry cloth. Do not spray any cleaning solution or water onto them. For a permanent solution, establish a barrier. Use the iRobot HOME App to create a Keep Out Zone along the stair edge. Alternatively, use the Dual Mode Virtual Wall barrier in Virtual Wall mode. Place it at least 8 feet from the Home Base, positioning it to block the stair opening. If that didn't work: Excessive sunlight or very dark flooring at the stair edge can interfere with the cliff sensors' infrared beams. You may need to adjust the barrier's position. Heads up: Always use a physical barrier for balconies to prevent access.

Question 5

my irobot roomba i3+ evo is making a loud grinding noise from the bottom, what should i check?

Accepted Answer

A grinding noise is almost always debris wrapped around the brushes or a problem with the front caster wheel. Power off the robot and flip it over. Check the Multi-Surface Brushes: Pinch the brush frame release tabs, lift, and remove the brushes. Remove any hair or debris wrapped around the ends and from the square and hexagonal pegs on the opposite side. Reinstall, matching the brush peg shapes to the icons in the cleaning head module. Check the Edge-Sweeping Brush: Use a small screwdriver to loosen the screw holding it in place. Pull to remove the brush, clear any hair or debris, and reinstall it. Check the Front Caster Wheel: Pull firmly on the front wheel module to remove it, then pull the wheel out of its housing. Remove any hair or debris from the axle and the cavity. Reinstall, ensuring it clicks back into place and spins freely. If that didn't work: Remove the bin and check the vacuum path inside the robot for any large obstructions like a pebble or a twist-tie that might be caught in the fan. Heads up: A front wheel clogged with hair and debris that isn't spinning freely can damage your floor. If cleaning doesn't stop the noise, contact Customer Care.

Question 6

can i use my roomba i3+ evo to clean up a small liquid spill?

Accepted Answer

No, absolutely not. You cannot use your Roomba i3+ EVO to clean up a small liquid spill. It is for dry floor use only. If you run it over a wet area, you risk severe damage to the robot's internal electronics. You also create a safety hazard and risk clogging and ruining the filter, which is not washable. For a spill, you need to clean it up manually with a towel or mop first. Let the floor dry completely before sending the robot out. Do not allow your robot or its Home Base to become wet. Heads up: The same goes for anything that's burning, smoking, or sharp objects like glass. It's a vacuum for dry debris like dust, dirt, and pet hair, not a wet-dry vac.

Question 7

roomba i3+ evo light ring is solid red and it won't start cleaning, what does that mean?

Accepted Answer

A solid red light ring means the robot's bin is full and needs to be emptied. It won't start a new job until you do. Press the bin release button on the top of the robot and remove the dust bin. Open the bin door and tap the filter against your trash container to empty it. Before reinserting, check the full bin sensors inside the robot and on the bin door. Wipe them with a clean, dry cloth. Buildup here can trigger a false full signal. Make sure the filter is correctly installed with the ridged grips facing out. The robot will not run if the filter is missing or in wrong. Place the bin back into the robot until it clicks. If that didn't work: The charging contacts on the robot or the Home Base might be dirty, preventing a proper connection and causing a power issue. Wipe both the robot's and the Home Base's charging contacts with a clean, dry cloth or a melamine foam pad to remove debris. Heads up: Do not wash the filter. Remove it before rinsing the bin with warm water, and make sure the bin is completely dry before reassembly.

Question 8

my roomba i3+ evo keeps getting stuck under my couch, anyone else have this issue?

Accepted Answer

This usually happens because the robot is trying to clean an area it can physically fit into, but then can't find its way back out. There's a specific setting in the app for this. First, use the iRobot HOME App to set up Keep Out Zones. Draw a virtual boundary around the area under the couch to tell the robot to avoid it entirely. If you don't have the app connected, you can use the included Dual Mode Virtual Wall barrier. Set the switch to Halo mode and place it near the couch leg. This creates a circular invisible barrier about 12 inches across that will stop the robot from entering that zone. If that didn't work: The other possibility is that the robot's front caster wheel is jammed with hair or debris, which affects its steering and ability to back out. Pull firmly on the front wheel module to remove it, then pull the wheel out of its housing. Clear any wrapped hair from the axle and inside the cavity. Make sure it clicks back in place and spins freely. Heads up: A clogged front wheel that isn't spinning freely can actually damage your floor over time. If cleaning it doesn't fix the steering, you should contact iRobot Customer Care.

Question 9

how do i stop my roomba i3+ from falling down the stairs? my home base is in the hallway near them.

Accepted Answer

You need to move your Home Base. This is a critical safety step to prevent the robot from tumbling down. Unplug the Home Base and pick it up. Find a new location that is at least 4 feet (1.2 meters) away from the top of the stairs. This distance is required in front of the Home Base and to both sides. Ensure there is at least 1.5 feet (0.5 meters) of clear space on both sides of the Home Base and 4 feet in front of it for proper docking. Plug it back in and re-dock your robot. If that didn't work because your layout won't allow a 4-foot clearance, you must use a physical barrier. If the room contains a balcony or stairs, a physical barrier should be used to prevent access and ensure safe operation. Heads up: The robot moves on its own. Always be aware when walking in the area it's operating in to avoid stepping on it. Supervise small children and pets when the robot is running.

Question 10

my roomba i3+ evo's suction seems really weak all of a sudden, it's not picking anything up.

Accepted Answer

Clogged filter or blocked vacuum path. Performance drops if these are not maintained. Remove and empty the bin. Open the bin door. Remove the filter by grasping both ends and pulling out. Tap it firmly against your trash container to dislodge debris. Do not wash the filter. Reinsert the filter with the ridged grips facing out. Close the bin door and reinstall the bin. With the bin removed, check the vacuum path inside the robot and clear any debris. If that didn't work, replace the filter. It should be replaced every two months. A fully clogged filter cannot be cleaned effectively. Maintenance schedule: Clean the filter once a week (twice if you have a pet). Clean the full bin sensors every two weeks. Wash the bin as needed with warm water, ensuring it is completely dry before re-use.

Question 11

can i store my roomba i3+ evo in the garage? it's not temperature controlled.

Accepted Answer

No. The robot and its lithium-ion battery must be stored in room temperature environments only. For long-term storage, follow this procedure:Remove the robot from the Home Base. Hold down the CLEAN button for 10 seconds. All indicators will turn off. This turns the battery off. Store the robot in a cool, dry place indoors. If that's not possible and you must ship or store it elsewhere, the battery must be turned off using the steps above to meet safety regulations. Package the robot securely. Heads up: Do not open, crush, or heat the battery above 176°F (80°C). Do not short-circuit the terminals. Periodically inspect the battery pack for damage or leakage. Do not charge a damaged battery.

Question 12

roomba i3+ evo just beeps at me and the light ring does a red sweep towards the back. it's not emptying.

Accepted Answer

Yeah, this one's common. That red sweeping light means the robot senses its bin is full and needs to be emptied, but something's blocking the process. First, manually empty the bin. Press the bin release button, pull the bin out, and open the bin door to empty it. Tap the filter against your trash container to dislodge fine dust. Make sure the bin door closes completely. If that didn't work, the full bin sensors are dirty. Every two weeks, you need to wipe the inner sensors with a clean, dry cloth. Remove the bin, open the bin door, and you'll see the sensors inside. Give them a good wipe. Heads up: Never wash the filter. Remove it before washing the bin with warm water (the bin is not dishwasher safe). The robot will not run if the filter is not installed correctly with the ridged grips facing out.

Question 13

my roomba i3+ evo is making a loud grinding noise when it runs, sounds like it's coming from the brushes.

Accepted Answer

Debris is wrapped around the brush axles. Immediate cleaning is required to prevent motor strain. Turn the robot over. Pinch the brush frame release tabs and lift to remove the brush cage. Pull out both Multi-Surface Brushes. Remove the brush caps from each end of the brushes. Clear all hair and debris from beneath the caps and reinstall them. On the opposite side of each brush, remove any hair or debris wrapped around the square and hexagonal pegs. Reinstall the brushes, matching the shape of the pegs (square or hexagon) with the icons in the cleaning head module. If that didn't work, check the Edge-Sweeping Brush. Remove it by loosening its screw, clear any obstructions from its shaft, and reinstall it. Heads up: Clean these brushes once a month, or twice a month if you have a pet. Replace them every 12 months, or sooner if visible wear appears.

Question 14

roomba i3+ evo won't charge on the home base, the light ring is red and pulsing. i've tried repositioning it.

Accepted Answer

Dirty charging contacts are the primary cause. The failure to maintain cleanliness results in loss of charging ability. Wipe the three circular charging contacts on the bottom of the robot with a clean, dry cloth. Wipe the two charging contacts on the Home Base with a clean, dry cloth. You can use a melamine foam pad to remove built-up debris. If that didn't work, verify the power supply.Ensure you are using only the provided power supply cord plugged into a standard household AC outlet. Do not use any other cord or a power converter. Check that the Home Base cord is not damaged. If it is, it must be replaced by contacting Customer Care. Prevention: Keep the robot and Home Base in a dry location. Do not handle them with wet hands.

Question 15

my roomba i3+ evo keeps getting stuck on my rug and flashing a red light, what's wrong?

Accepted Answer

The most likely cause is a jammed or overloaded front caster wheel. Hair and debris wrap around the axle, preventing it from spinning freely. Turn the robot over. Pull firmly on the front wheel module to remove it from the robot. Pull the wheel straight out of its housing. Remove all hair and debris from the wheel axle and the inside of the wheel cavity. Push the wheel back into the housing until it clicks into place. Reinstall the module. If that didn't work, check the Edge-Sweeping Brush. Use a small screwdriver to loosen the screw, remove the brush, and clear any tangled hair or threads from its shaft. Reinstall and tighten the screw. Heads up: A clogged front wheel that isn't spinning can damage your floor. If cleaning it doesn't fix the issue, contact iRobot Customer Care.
