Settings for the 761 can be operated both manually or by remote control. The amount of functions it has makes for a pretty versatile machine.
On the top of the device itself are the manual buttons. ‘Clean’ mode will activate the robot to do a cleaning cycle without any programming, pretty much like an automatic setting. It has color-coded lights to alert you to the battery level. Green means it will operate and has power. When it turns to orange, it is telling you it is in need of a recharge.
761 Go Home…
If you press the ‘dock’ button, the device will cancel cleaning and return to the charging station. A homing beacon will get the 761 back to wherever you have placed the dock.
If, however, you are not present, and the battery is running low, it will return to the dock to recharge automatically. Once a full charge has been completed, it will remember where it cleaned up to, and resume cleaning duties from that point in your room.
Set and forget…
The ‘clock’ and ‘schedule’ buttons will allow you to create a weekly cleaning schedule for the cleaner. You can program the 761 for up to seven cleaning sessions per week. This is a very good function to have because it lets you control future cleaning dates and times. You do not have to be present for the 761 to be working. Set it to clean while you are at work, and on your return, the vacuuming chore will have been completed without any worry.
Although the 761 can do the cleaning by itself, it can not empty the bin. So if you use the ‘clock’ and ‘schedule’ settings, you must remember to empty the dirt to the trash after every session. If you do not, you run the risk of it not completing the next cycle because it is already full.
More vigorous cleaning…
There is also a ‘spot’ setting. If you have a specific area that needs a more concentrated vacuuming because of a spillage, for example, this function will see to it that that certain area gets a more vigorous vacuum.
These functions can all be controlled by the remote control, which is included with purchase.
Three Stage Cleaning System
The Roomba 761 has a patented three stage cleaning system that is able to suck up larger floor dirt and debris, finer dust particles, and will also seal away the finest of allergens down to as small as ten microns. Some cleaners stir up but do not effectively capture this micro dust, which can cause irritations.
The 761, however, seems to manage a good job of containing this. iRobot even makes the bold claim that the cleaner will capture and seal 99.97% of all contaminants.
Suck up the dirt…
The 761 starts by sweeping corners and edges using a 27 degree angled edge sweeping brush. This knocks up all dirt and debris to allow the dual counter-rotating brushes to roll over, grab and move the dirt into the path of the powerful vacuum. The strong suction makes it possible to pull all the dirt and hairs form the brushes and into the container bin.
The suction is really nice and powerful and along with the rotating brushes, does a fine job of cleaning up your floors. The efficient vacuum pulls all debris, muck, and hair from the brushes and directs it all into the container bin.
Great for pets…
If you have a pet at home, do not worry about this cleaner coping with your pet’s hair. The tangle free brushes will whip it up for the vacuum to suck into the container.
The 761 has been designed to vacuum up pet hair, which is a very good feature to have. We would still recommend though, from time to time, that you manually clean out any stray hairs from the brush. Hair always tangles, and if left in the brush, performance will become restricted.
Dirt Detection Technology
Another cool feature that we especially like with the 761 is the dirt detection sensors. This means the machine itself can detect a dirtier area on the floor and will spend more time cleaning that place. For parts of your room that see more action (high traffic zones iRobot call them), so accumulate more dirt, the 761 will concentrate on there more than behind the couch, for instance.
The Roomba 761 comes with a full set of smart sensors inbuilt around the edge of the diameter. These aid it to find its own way around your rooms and the furniture within them. And due to the low profile of the body, this will travel under the lowest of couches, coffee tables, and shelving.
To avoid actually bumping into walls and furniture, it also has two virtual wall sensors.
Auto-Adjust Cleaning Head
The sensors are also able to detect the type of floor surface it is vacuuming and can adjust the height to suit as well as the power output necessary. Vinyl, tiled, and smooth wooden floor surfaces will not need the same amount of height and hard work to vacuum as, say, low pile carpet.
