iRobot Roomba s9+ cleans all floor types, this feature comes in handy, since different rooms inside your home may have various types of flooring i.e. carpets. When a robot vacuum is advertised as being able to clean all floor types, this implies that the vacuum is capable to clean a wide range of flooring materials without much significant issues.
The robot vacuum's ability to generate a digital map of its cleaning space is one of the commonly asked-for features. This map allows the robot to "understand" the layout of the space. Mapping and navigation can be used for several purposes, e.g.
the iRobot Roomba s9+ having the mapping feature can dedicate efficient cleaning in the mapped-out areas without accessing those that are not. iRobot Roomba 981 also has the mapping and navigation feature, navigation states how the robot vacuum moves around the cleaning area. Mapping and navigation often go hand in hand to help the vacuum navigate to the mapped-out areas to be cleaned leaving out those that aren't.
iRobot Roomba s9+ has an obstacle sensor, this serves the purpose of detecting and identifying obstacles in the robot's path, this allwos it to navigate around them thus avoiding collisions. Also, the iRobot Roomba 981 has this sensor, obstacle sensors work together to provide the robot vacuum with a better understanding of its surroundings, enabling it to navigate around furniture, walls, and other objects when cleaning a room and avoiding damage to both the robot and its obstacles. The iRobot Roomba s9+'s dustbin capacity is at 0.4L, dustbin capacity determines how much dust, dirt, and pet hair the robot vacuum holds before it can be emptied.
iRobot Roomba 981, at 0.5L
has more capacity than the iRobot Roomba s9+ with a difference of 0.1L
The dustbin capacity varies widely among robot vacuum models, and the capcity you choose should be based on your cleaning needs and the size of the area you want to clean. Different floor types require a robot vacuum to be at a given ground clearance so as to optimize performance. The iRobot Roomba s9+ adjusts its height to match this requirement, for example, it may raise itself slightly when transitioning to a carpet to allow for effective suction, and then lower itself on hard floors to ensure the brushes make good contact.
iRobot Roomba s9+ weighs 3.7kg, robot vacuums are generally designed to be lightweight and compact to easily get around and portability. The iRobot Roomba 981, at 4kg
weighs more than the iRobot Roomba s9+ with a difference of 0.3kg. It's advisable to take in consideration the weight of the robot vacuum when choosing a model, and that's if you plan to carry it up and down stairs
iRobot Roomba s9+ has a width of 311mm, aslo known as its cleaning path width, is the width of the area that the robot vacuum can properly clean in one go.
The width of a robot vacuum is key as it can affect its efficiency and the time it takes to clean a room
The iRobot Roomba 981, at 351mm
measures more in width than the iRobot Roomba s9+ by 40mm. A wider cleaning path can cover more ground in a single pass, reducing the time it takes to clean a room. iRobot Roomba s9+'s height measures 89mm, here you are looking at the measurement from the bottom to its highest point.
Height is a key consideration, especially if you have obstacles with low clearance in your home. The iRobot Roomba 981, at 92mm
measures more in height than the iRobot Roomba s9+ by 3mm. When choosing a robot vacuum, ensure that the robot vacuum can go under the furniture and navigate effectively in your living space without getting stuck or causing damage.
The battery power of a robot vacuum cleaner is important as it determines how long the vacuum can operate on a single charge. It is typically measured in milliampere-hours (mAh), iRobot Roomba s9+'s battery power is 3,300mAh
iRobot Roomba 981, at mAh3,000
has less battery power than the iRobot Roomba s9+ with a difference of only
A bigger capacity usually means longer battery life which can be beneficial if you have a large room or if you would like the robot vacuum to complete cleaning cycles with fewer interruptions to recharge. The operating time of a robot vacuum cleaner refers to the time the vacuum can clean continuously on a single charge before it needs to be recharged.
iRobot Roomba s9+'s operating time is 1h
iRobot Roomba 981, at 2h
lasts more than the iRobot Roomba s9+ by 1h
Always plan cleaning cycles around the vacuum's operating time to maximize efficiency and prevent "incomplete work" between charge intervals. iRobot Roomba s9+ has a dirt sensor, dirt sensors are designed to detect the concentration of dirt, dust, or debris in the area being cleaned and based on their readings adjust the vacuum's cleaning behavior during operation. Self-emptying bins or automatic dirt disposal systems like the iRobot Roomba s9+, are advanced robot vacuum models that have a convenient feature to empty their dustbins automatically.
iRobot Roomba s9+ supports a smartphone app, through which you can control and monitor the vacuum remotely through your smartphone or tablet. Both the iRobot Roomba 981 and iRobot Roomba s9+ have mobile application support, mobile apps enhance your experience by providing convenience, and ease update of features and functionalities. This feature in robot vacuum cleaners is intended to reduce the likelihood of the robot vacuum getting trapped while cleaning.
Robot vacuums such as the iRobot Roomba s9+ are equipped with various sensors and technologies to move around obstacles and avoid getting stuck, but the effectiveness of this feature can vary among different models. Both the iRobot Roomba 981 and iRobot Roomba s9+ have the "anti-stuck" feature, however clearing clutter, ensuring proper cable management, and creating clear paths for the vacuums helps to further reduce the chances of becoming stuck while cleaning. These virtual barriers are typically set up and managed via the robot vacuum's mobile app, similar to no-go zones, these barriers are designed to help you control and restrict where the robot vacuum can and cannot go during cleaning.
iRobot Roomba s9+ has a route mapping feature which enables it to create a map of your space and schedule efficient cleaning routes. This mapping capability improves the vacuum's ability to work effectively and systematically. Route mapping is an important feature as it enables robot vacuums such as the iRobot Roomba 981 to adapt to the layout of your space to work more efficiently and reduce the possibility of missing certain spots.
Voice prompts are notifications that the vacuum emits to provide you information on the different states of the vacuum. iRobot Roomba s9+ has this feature
iRobot Roomba 981 also supports voice prompts, this feature can be useful for you who like audible notifications or users who have visual impairments. Auto-docking is a feature in robot vacuum cleaners that indicates the vacuum's ability to return to its docking station when predetermined conditions are met such as done with cleaning, battery running low, or any malfunction.
Both iRobot Roomba 981 and iRobot Roomba s9+ support this feature, considered a convenient feature because it ensures that the robot vacuum keeps its charge and readiness for cleaning without requiring manual intervention. Most robot vacuum cleaners such as iRobot Roomba s9+ come having an "anti-fall" feature. This feature is designed to save the robot vacuum from falling off stairs, ledges, or other elevated surfaces, hence its safety while cleaning.
This safety feature that is also available on the iRobot Roomba 981 is key in mitigating accidents and keeping the robot vacuum from damage. It gives you peace of mind knowing that the vacuum will not fall down a flight of stairs during its cleaning cycle.
