Has Twin Side Brushes

Shark AI has twin side brushes, these brushes can be beneficial for specific cleaning tasks, since they help the robot vacuum sweep dirt and debris from corners and along edges.

Automatically Adjusts Its Height

Different floor types require a robot vacuum to be at a given ground clearance so as to optimize performance. iRobot Roomba 621 adjusts its height to match this requirement, for example, it may raise itself slightly when moving to a carpet to allow for effective suction, and then lower itself on hard floors to ensure the brushes make good contact.

Weight

The iRobot Roomba 621 weighs 4.3kg, robot vacuums are commonly designed to be lightweight and compact for easy maneuverability and portability.

The Shark AI, at 3.2kg is lighter than the iRobot Roomba 621 with a difference of 1.1kg. It's important to take in consideration the weight of the robot vacuum when choosing a model, especially if you plan to carry it up and down stairs

Width

iRobot Roomba 621 has a width of 340mm, often referred to 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

Shark AI, at 348mm measures more in width than the iRobot Roomba 621 by 8mm. A wider cleaning path can cover more ground in a single pass, reducing the time it takes to clean a room.

Height

iRobot Roomba 621's height measures 92mm, 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 limited clearance in your home.

Shark AI, at 104mm measures more in height than the iRobot Roomba 621 by 12mm. 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.

Cleaning Performance And Power Features

Battery Power

The battery power of a robot vacuum cleaner is important as it determines how long the vacuum can operate on a single charge. Battery capacity is measured in milliampere-hours (mAh), iRobot Roomba 621's battery power is 4,500mAh

Operating Time

The operating time of a robot vacuum cleaner refers to the amount of time the vacuum can clean continuously on a single battery charge before it needs to return to its charging dock for recharging. iRobot Roomba 621's operating time is 1.5h

The Shark AI, at 2h lasts more than the iRobot Roomba 621 with a difference of 0.5h Always plan cleaning cycles around the vacuum's operating time to maximize efficiency and prevent "incomplete work" between charge intervals.

Charge Time

iRobot Roomba 621 has a charge time of 3h, the charge time of a robot vacuum cleaner refers to the amount of time it takes for the vacuum's battery to recharge fully after it has been depleted during a cleaning cycle.

Shark AI, at 4h charges for longer than the iRobot Roomba 621 by 1h. Charge time is an important factor to consider when choosing a robot vacuum, as it determines how long you'll need to wait before the vacuum begins its next cleaning cycle.
