Choosing the right robot vacuum for your needs can be overwhelming, especially when comparing high-end models like the iRobot Roomba j7+ and the Roborock S7 MaxV Ultra. 

Both offer impressive features and boast intelligent navigation, powerful cleaning, and convenient self-emptying docks. However, some key differences might influence your decision.

When tackling dirt, dust, and debris, the Roomba j7+ and the S7 MaxV Ultra stand out as formidable contenders. They excel at cleaning various floor surfaces, leaving your home sparkling.

The Roomba j7+ employs a dual rubber brush system, effectively grabbing dirt and debris from carpets and hard floors. These brushes are designed to handle fine dust and larger particles, ensuring a thorough cleaning across your living space.

The S7 MaxV Ultra, however, takes things a step further with its innovative mopping feature. It boasts a spinning mop brush with increased pressure, ideal for tackling stubborn messes on hard floors.

This technology aims to simulate the act of manual scrubbing, delivering a deeper clean than the simple drag mop used by the Roomba j7+. While both robots offer mopping capabilities, the S7 MaxV Ultra holds the edge regarding the scrubbing power and potential for a more polished finish on hard surfaces. 

However, the Roomba j7+ might suit users prioritising effective vacuuming across carpets and hard floors.

Navigation and obstacle avoidance

How these robots navigate your home is crucial to their cleaning efficiency and overall effectiveness. Here, we see a clear distinction between the two technologies employed:

LiDAR navigation (S7 MaxV Ultra)

This advanced technology utilises laser beams to map your home environment accurately. The S7 MaxV Ultra creates a detailed map, allowing it to plan efficient cleaning paths effectively and avoid obstacles. This method functions well regardless of lighting conditions, ensuring consistent performance even in dimly lit rooms.

Camera-based navigation (Roomba j7+)

While still effective, the Roomba j7+ relies on a camera-based system for navigation. This method can be susceptible to challenges in low-light environments, potentially hindering its ability to accurately map and navigate your home. This factor can lead to inefficiencies in cleaning patterns and potentially missed areas.

Beyond essential obstacle avoidance: The power of object recognition

Both robots offer obstacle avoidance capabilities, but the S7 MaxV Ultra takes it a step further with its advanced object recognition technology. This innovative feature allows it to identify and avoid objects like shoes, cables, and pet waste. This feature significantly reduces the risk of tangled messes or damage to delicate items, offering peace of mind to users with pets or cluttered living spaces.

The Roomba j7+, while capable of fundamental obstacle avoidance, lacks the advanced object recognition of the S7 MaxV Ultra. It may be more prone to getting stuck on objects or bumping into delicate items, requiring more user intervention.

Emptying frequency and capacity

Although both docks have automatic dustbin emptying systems and self-emptying docks, there are some significant distinctions. With its 3L dust bag, the S7 MaxV Ultra requires less frequent emptying than the Roomba j7+, which only has a 1L dustbin. 

Additionally, the S7 MaxV Ultra’s dock automatically washes and air-dries the mop, reducing user maintenance.

Easy-to-use apps are available for the Roborock S7 MaxV Ultra and the iRobot Roomba j7+ to customise your cleaning experience. With these apps, you can plan cleaning sessions, designate particular cleaning zones, and keep track of your robot’s cleaning history. 

But the S7 MaxV Ultra app goes one step further and offers a more sophisticated map with specifics about object detection. This trademark gives you a more thorough picture of your robot’s cleaning performance, enabling you to see precisely where it has detected and avoided impediments. 

Furthermore, both robots can be controlled hands-free via popular voice assistants like Google Assistant and Amazon Alexa for added convenience.

As for the pricing, the Roborock S7 MaxV Ultra comes at a significantly higher price point compared to the iRobot Roomba j7+.

The Roborock S7 MaxV Ultra is the clear winner for those seeking the most advanced features and cleaning performance. Its superior mopping, object recognition, and self-emptying dock with mop-washing capabilities elevate the user experience. However, its significantly higher price tag might be a dealbreaker for some.

The iRobot Roomba j7+ remains a compelling option for those seeking a reliable and powerful robot vacuum at a more accessible price point. Its strong suction, dual brushes, and user-friendly app make it a solid choice for most cleaning needs.

Ultimately, the best choice depends on your priorities and budget. Consider which features are most important to you and whether the additional functionalities and advanced technology of the S7 MaxV Ultra justify its higher price than the capable and more affordable Roomba j7+.
