Design

The design of all 600 series robot vacuums is distinguished by its simplicity and sleekness. The robot's outline is round, with a semicircular bumper that extends slightly beyond the circle. The edges of the device are rounded and beveled at the bottom. This helps it overcome obstacles and prevents it from getting stuck. The iRobot Roomba has a convenient, curved handle that can be lifted for carrying.

The iRobot Roomba 631's body is made of plastic and has a matte finish. It features a black and gray color scheme. The front of the device features a mirror-smooth control panel framed by a yellow and green border. The panel consists of three mechanical buttons with a silver finish and backlit indicators.

The side panel features a soft-touch bumper with an upward-facing infrared sensor. It scans the room and detects the location of the base and motion limiter.

When viewing the robot vacuum cleaner from the rear, you can see the contact pads, two side wheels, a swivel roller, one side brush, the main brushes, the bottom of the dust container, and infrared height difference sensors.

Functional capabilities

The robot vacuum cleaner has two main operating modes:

1. Automatic – the robot cleans the room at its discretion.
2. Local – thorough cleaning of a specified area. The device must be moved manually.

These modes are activated by pressing the buttons on the body:

• Clean – start automatic mode.
• Spot – local cleaning of a specific place.
• Dock – this button is used to forcefully return the device to the charging station.

When cleaning, the iRobot Roomba 631 moves along the following trajectories:

1. Spiral – when cleaning a specific area, the robot vacuum cleaner moves along a spiral path with a small radius.
2. Moving along walls – effective cleaning of surfaces around the perimeter, bypassing furniture and other obstacles.
3. Room Crossing – The machine crosses the room in different directions, cleaning each area.
4. Recognizing the dirtiest spots – when the maximum accumulation of dirt is detected in a room, a special Dirt Detect indicator lights up on the device, and the vacuum cleaner cleans that area more thoroughly.

A plus is the presence of a special function that allows the robot vacuum cleaner to successfully get out of difficult places, as well as an anti-tangle system, thanks to which the robot vacuum cleaner does not get tangled in wires and fringes.

The cleaning area can be spatially limited thanks to the presence of virtual wall, included in the basic kit of the device.

A distinctive feature of the iRobot Roomba 631 is its patented three-level cleaning system:

1. The paddle brush cleans the surface along baseboards and in the corners of the room.
2. A pair of counter-rotating brushes sweep dirt and dust towards the dust collector.
3. The device sucks up the remaining debris, settling the smallest particles on the filter.
