Features

Automatic Recharge Function

The Roomba j9+ automatically returns to its Clean Base to recharge when the battery is low. This ensures that the robot is always ready for its next cleaning session and can complete large cleaning jobs without interruption. This feature provides a seamless and hands-free cleaning experience, making it ideal for busy households.

Scheduled Cleaning Function

The Roomba j9+ allows you to schedule cleaning sessions via the iRobot Home App. You can set specific times and days for the robot to clean, ensuring that your floors are always clean without any effort. This feature is particularly useful for maintaining a consistent cleaning schedule while you're away from home or asleep.

Virtual Wall Function

The Roomba j9+ allows you to set up Keep Out Zones via the iRobot Home App. These virtual boundaries prevent the robot from entering certain areas, such as pet feeding zones or delicate spaces. This feature provides greater control over the cleaning area and ensures that the robot avoids sensitive areas or obstacles.

Carpet Boost Function

The Roomba j9+ automatically adjusts its suction power when it detects carpet, providing a deeper and more thorough clean. This ensures effective dirt and debris removal from carpets and rugs, leaving them looking their best. The carpet boost function optimizes cleaning performance on different floor types, ensuring a consistent clean throughout your home.

Object Detection Function

The Roomba j9+ uses PrecisionVision Navigation to detect and avoid obstacles like furniture, shoes, and pet waste. The robot can navigate around objects more efficiently, reducing the risk of bumping into things and getting stuck. This minimizes pre-cleaning preparation and ensures a smooth cleaning process, even in cluttered environments.

Multi-Floor Mapping Function

The Roomba j9+ can store maps of multiple floors in your home, allowing it to clean each floor efficiently. The robot remembers the layout of each floor and cleans accordingly, eliminating the need to remap each floor every time you move the vacuum. This feature is ideal for multi-story homes, providing a seamless cleaning experience across different levels.

Frequently Asked Questions (FAQ)

Q.I'm worried about the Roomba j9+ getting stuck on pet waste. Does it really avoid it?
A.The Roomba j9+ has PrecisionVision Navigation to identify and avoid obstacles, including pet waste. It also comes with a P.O.O.P. (Pet Owner Official Promise). According to the product overview, if it doesn't avoid pet waste, iRobot will replace your robot for free, but please refer to the iRobot website for the full details and any additional terms and conditions.
Q.How much maintenance is involved with the Roomba j9+?
A.The Roomba j9+ self-empties into a bag that holds up to 60 days of debris, reducing the frequency of emptying. However, staff confirmation indicates that keeping the filters clean is important to maintain suction. One staff member mentioned needing to unclog it once after the first run. Also, like all robot vacuums, it may not reach tight corners, requiring some manual cleaning.
Q.I have thick carpets. Will the Roomba j9+ be effective on them?
A.According to the product overview, the Roomba j9+ has stronger suction compared to Roomba Combo i Series robots and a 3-stage cleaning system. One staff member reported that it's very effective on hardwood and thin carpets. However, they noted it's not as effective on heavier carpets, so a standard vacuum might still be needed. Overall, it sounds like the Roomba j9+ will keep the house free of cat hair and tracked kitty litter.

A.One staff confirmation reported experiencing software upgrade issues that left the unit unusable and unconnectable, which they found to be a trend online.

The staff rating distribution shows that 52% of ratings are 'Highest Quality' while 21% are 'Lowest Quality'. Please consider this distribution when purchasing the product.
Q.How well does the Roomba j9+ handle mapping and navigating my home?
