iRobot Roomba s9+ cleans all floor types, this feature is essential, as different rooms inside a home may have various types of flooring i.e. carpets. When a robot vacuum is stated as being able to clean all types of floors, this implies that the vacuum is capable to clean most flooring materials without any significant issues.
The robot vacuum's ability to generate a map of its cleaning area is one of the commonly asked-for features. The map it creates allows the robot to "understand" the layout of the desired space. This can be used for several purposes, e.g.
the iRobot Roomba s9+ having the mapping feature can provide efficient cleaning in the mapped-out areas keeping out of those that are not. The 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 ignoring those that aren't.
iRobot Roomba s9+ has an obstacle sensor, this serves the purpose of detecting and identifying obstacles in the robot's route, 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 comprehensive understanding of its environment, enabling it to navigate around furniture, walls, and other objects when cleaning a room thus preventing damage to both the robot and its obstacles. The iRobot Roomba s9+'s dustbin capacity is at 0.4L, dustbin capacity indicates how much dust, debris, and pet hair the vacuum holds before it can be emptied.
iRobot Roomba 981, at 0.5L
has more capacity than the iRobot Roomba s9+ by 0.1L
The dustbin capacity varies widely among different robot vacuum models, and the size you choose should depend 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+ can adjust its height to match this requirement, for example, it may raise itself slightly when moving to a carpet to enable effective suction, and then lower itself on hard floors to make sure the brushes make good contact.
The iRobot Roomba s9+ weighs 3.7kg, robot vacuums are commonly designed to be lightweight and compact for easy maneuverability and portability. iRobot Roomba 981, at 4kg
weighs more than the iRobot Roomba s9+ with a difference of 0.3kg. It's advisable to consider the weight of the robot vacuum when choosing a model, especially if you plan to carry it up and down stairs
iRobot Roomba s9+ has a width of 311mm, often referred to as its cleaning path width, refers to 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 duration it takes to clean a space
iRobot Roomba 981, at 351mm
measures more in width than the iRobot Roomba s9+ with a difference of 40mm. A wider cleaning path can cover more ground in a single pass, shortening the time it takes to clean a room. iRobot Roomba s9+'s height measures 89mm, here you are considering the measure from the bottom to its highest point.
Height is a key consideration, especially if you have obstacles with limited clearance in your home. The iRobot Roomba 981, at 92mm
measures more in height than the iRobot Roomba s9+ with a difference of 3mm. When choosing a robot vacuum, ensure that the robot vacuum can fit 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 run on a single charge. It is typically measured in milliampere-hours (mAh), iRobot Roomba s9+'s battery power is 3,300mAh
The 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 of advantage if you have a large home or if you would like the robot vacuum to complete cleaning cycles with less interruptions to recharge. The operating time of a robot vacuum cleaner refers to the amount of time the vacuum can clean continuously on a single charge before it needs to be recharged.
iRobot Roomba s9+'s operating time is 1h
The 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 space being cleaned and can be used to 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, that allows you to control and monitor the vacuum without getting to it physically but 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 eliminate the chance of the robot vacuum becoming trapped while cleaning.
Robot vacuums such as the iRobot Roomba s9+ are equipped with various sensors and technologies to navigate around obstacles and avoid getting trapped, however the effectiveness of this feature can vary among different models. Both the iRobot Roomba 981 and iRobot Roomba s9+ have the "anti-stuck" feature, but clearing clutter, ensuring proper cable management, and creating clear paths for the vacuums helps to further eliminate the chances of becoming stuck during cleaning. These virtual barriers are set up and controlled through the robot vacuum's mobile app, similar to no-go zones, these barriers are setup to enable you control and restrict where the robot vacuum can and cannot go while cleaning.
iRobot Roomba s9+ has a route mapping feature which enables it to generate a map of your home and schedule efficient cleaning routes. This mapping capability enhances the vacuum's ability to clean effectively and systematically. Route mapping is a valuable feature as it makes it possible for robot vacuums such as the iRobot Roomba 981 to adapt to the layout of your home to clean more efficiently and minimize the risk of missing certain spots.
Voice prompts are notifications that the vacuum emits to give you information on the different states of the vacuum. iRobot Roomba s9+ has this feature
The iRobot Roomba 981 also supports voice prompts, this feature is useful for you who like audible notifications or users who have visual impairments. Auto-docking is a feature that indicates the vacuum's ability to autonomously return to its docking station when predetermined conditions are met such as getting work done, 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 maintains its charge and readiness for cleaning without requiring manual intervention. Modern robot vacuum cleaners such as iRobot Roomba s9+ come having an "anti-fall" feature. This feature is intended to prevent the robot vacuum from falling off stairs, ledges, or other elevated surfaces, ensuring its safety while cleaning.
This safety feature that is also available on the iRobot Roomba 981 is essential in preventing 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.
