Clean supreme

Clean your floor like never before with the iRobot Roomba 870 Vacuum Cleaning Robot. Equipped with revolutionary AeroForce performance cleaning system, the Roomba 870 removes up to 50% more dirt, dust, hair and debris from all floor types so you can spend more time doing the things you love, that is, unless you cleaning. The HEPA-filtered bin traps dirt, particulates and allergens making ideal for homes with pets and allergy sufferers. AeroForce uses three technologies to deliver the ideal balance of vacuum suction and debris extraction.

Tangle-Free AeroForce Extractors

Tangle-Free AeroForce Extractors

Dual extractors grab and break down dirt and debris from any floor type with no hair tangles for you.

Airflow Accelerator

Airflow Accelerator

The accelerator brings the vacuum power right down to the floor surface, creating a sealed channel that concentrates airflow, drawing in more debris.

High-Efficiency Vacuum

High-Efficiency Vacuum

A compact and efficient high-powered motor provides a 5x improvement in air power than previous Roomba generations.

Keeping up with the cleaning just got easier

Thanks to Dirt Detect Series 2 technology, the Roomba 870 automatically locates dirt and debris and performs a concentrated clean in areas where its needed most. The spinning side brush pushes debris into the path of the extractors, making easy work out of dirt hidden in the wall edges. The Roomba 870 can be preset to clean when its more convenient for you, up to seven times per week. When the job is done, the Roomba will return to its docking station to recharge between cleanings and will even let you know when the bin is getting full.

Taking care of your cleaning and valuables

The Roomba 870 is equipped with iAdapt Responsive Navigation technology which scans the environment over 60 times a second via so that it can navigate its way around any shape or size of home, covering every area of floor multiple times for a complete clean. Cliff detection sensors avoid the Roomba 870 from falling down the stairs, while the light touch bumber accurately distinguishes between soft and solid barriers - allowing it to clean under curtains and bed skirts.

N.B. Please note, robot vacuums can struggle with black or dark areas. The drop-off sensors read these areas as a drop-off and will not cross over them. It is possible, however, to cover up these sensors to allow the robot to vacuum over dark areas. Just be sure to put a physical barrier in front of any real drop-off points to prevent damaging the unit.

Bristol GB Pet owner
So simple to use and so good at cleaning. Couldn't believe how well it works on wood flooring and rugs. Seamlessly moving from one to the other.
The only minor point is that I can't find in the instructions whether you have to finish the clean manually or whether it knows when the room is complete.

What if I am declined for finance?

When you're applying for finance you always need to remember that there is a possibility you will be declined.
