iRobot Roomba E5, Model 5150 - Features and Specifications

iRobot Roomba E5 Model 5150 features rather compact design, with diameter of 13.3 inches (33.8 cm) and height of 3.6 inches (9.2 cm) - such dimensions in combination with the onboard sensors allow the unit to freely clean floors even under and around common floor objects and obstacles like sofas, beds, furniture, walls, stairs and similar.

Unit weighs 7.2 pounds (3.26 kg) and if it gets stuck, it can be easily carried away by the user.

iRobot Roomba E5 comes with iRobot iAdapt Navigation System, allowing the unit to clean large floor areas and to return to the charging station when the cleaning task is over or when the battery charge drops below certain level.

However, iAdapt Navigation System doesn't allow 'Automatic Recharge and Resume' (only 'Automatic Recharge') - when the iRobot Roomba E5 recharges, it waits next scheduled cleaning task or it starts cleaning when instructed by the user.

When positioning charging station, it is important to leave some space around it free, to help the unit locate and dock its charging station.

iRobot Roomba E5 is WiFi enabled robot vacuum cleaner. It doesn't support the use of classic IR (Infra Red) remote control, but it can be controlled using onboard controls (limited control) or using iRobot HOME App (full control over the unit).

Also, it support the use of Amazon Alexa and Google Assistant.

roomba e5 2iRobot Roomba E5 uses so-called 3 Stage Cleaning System, consisting of one side-brush, dual multi-surface rubber brushes, combined with 1700 Pa suction - according the tests, iRobot Roomba E5 features 5X the air power of improved pick up performance when compared to the Roomba models of the 600 Series.

iRobot Roomba E5 features maximum climbing height of 0.71 inches (18 mm), allowing the unit to traverse and efficiently clean various floor types, including low- and medium-high pile carpets and bare floors like hardwood, vinyl, marble, tiles, laminate, linoleum etc.

While single side brush is intended for cleaning along the wall edges, or in the corners, dual rubber brushes are designed to flex and adjust and stay in contact with the floor under the robot, increasing the cleaning effect, especially when vacuuming pet and human hair, lint and similar debris.

Also, dual rubber brushes are designed to decrease hair tangles, decreasing maintenance tasks, saving both required time and effort.

Note: iRobot Roomba is typical robot vacuum, easy to use and maintain. However, just in case, when the unit arrives, be sure to read the manual.

Operating time of the iRobot Roomba E5 on the single battery charge is ~90 minutes, when vacuuming bare floors only. When vacuuming mixed floors or carpets only, operating time is shorter.

Charging time of the iRobot Roomba E5 depends on the state of the battery, but generally it is around 2-3 hours, after which the battery is fully charged and the unit is ready for another cleaning cycle.

Dirt cup capacity is 500 ml and is similar in size to the dirt cups of other robot vacuums in this class.

Since iRobot Roomba E5 doesn't support automatic dirt disposal, it is up to the user to remove the dirt when the dirt cup is full or periodically.

Air filtration is labeled as HEPA air filtration and is able to filter out 99% of small dust and other particles.

While dirt cup is washable, air filter is not - it is recommended to tap the air filter on the hard inner surface of the trashcan to clean it from small dust particles.

After some time, air filter should be replaced with the new one - on average, replace the air filter every 2-3 months.

dual mode wall barrierWhile iRobot Roomba E5 doesn't support mapping feature, in order to prevent the unit from entering certain areas, Dual Mode Virtual Wall Barriers are used.

Dual Mode Virtual Wall Barriers may be used in 'Virtual Wall Mode' and in 'Halo Mode'.

In 'Virtual Wall Mode' Dual Mode Wall Barriers emit the linear barrier to block openings up to 10 feet (3 meters) in length.

In 'Halo Mode', Dual Mode Virtual Wall Barriers create circular barrier some 2 feet (60 cm) in diameter from the center of device.

If required, Dual Mode Virtual Wall Barriers may be ordered later, when and if required.

iRobot Roomba E5 also features cliff/drop sensors that prevent the unit from falling of the stairs and collision sensors that prevent the unit from bumping into the walls, furniture and similar.

Also, iRobot Roomba E5 comes with Dirt Detect Sensors, allowing the unit to detect areas with larger amount of dirt and to clean such areas more thoroughly.
