Product description

Advantages of Roomba 891

Suction Power is Maximised

Compared to previous robot hoover of iRobot Roomba, the 800 series is equipped with a more powerful suction motor. Therefore, Roomba 891 offers a 5x stronger suction power compared to its precursors.


Low Maintenance Efforts

iRobot 891 is equipped with AeroForceTM Extractors. Those are brushless rubber rollers where pet hair can’t get tangled up. This technology reduces the maintenance efforts extremely.


iAdapt® Responsive Navigation

This patented cleaning system enables a spotless and thorough floor cleaning. The navigation has a quite random pattern for human eyes but it offers many advantages. Because by cleaning any part several times the Roomba 890/891 removes even stubborn dirt and dust.

Recommendable for Pet Owners and Allergy Sufferers 

HEPA Filter for Clean Air

Inside the dustbin of Roomba 890/891 there is mounted an efficient HEPA filter. It removes the smallest dust particles out of the air. Therefore, the robot hoover is suitable for allergy sufferers.


Strong Suction Power for Pet Hair

The enormous suction power and the brushless rubber rollers reliably remove pet hair. Because of the brushless system there is not pet hair tangled up in the brush like it is with competitive robot hoovers. Thus, Roomba 891 is really recommendable for pet owners.

For a Thorough Floor Cleaning

Clean Floors and Carpets

This robot vacuum is ideal for cleaning hard floors like parquet, laminate, tiles and the like. Also carpets are freed from dirt and dust.


Cleans Edges and Corners

With its long side brush iRobot 891 cleans along edges and corners. The side brush transports dirt and dust near the suction inlet where it is aspirated.


Dirt Removal under Furniture

The height of only 9,2 cm from Roomba 890/891 is really low. Therefor it is able to drive under beds and sofas. Such areas are hardly reachable with a normal vacuum cleaner.


Doorsteps are no Problem

The cheap robot hoover overcomes doorsteps and carpets with a height of 2 cm. That ensures a cleaning without interruptions.

Safe Operation due to modern Sensors

Roomba 891 with Fall Protection

This robot hoover is equipped with numerous anti-drop sensors. They help iRobot 890/891 to recognize stairs and other abysses. Thus, is can change its cleaning direction in time.


Obstacles are Cruised Around

With its bumper the iRobot 891 recognizes obstacles like furniture or decoration. As soon as it touches them with the bumper it changes its direction, continuing the cleaning.

Not an Old-Fashioned Robot Hoover

iRobot HOME App

iRobot 891 is controlled via App for Android and iOS. It can be downloaded free of charge. Through the App you can start, stop, programme and monitor the robot vacuum.


Useful Scheduling

Roomba 890/891 can be programmed to start cleaning at a pre-defined time. There can be set one starting time each weekday. Afterwards, it automatically returns to the charging station to get some power.


Protection Zone for Feeding Dishes

iRobot 891 is delivered with a useful Dual Mode Virtual Wall. It can either be used as an invisible boundary or as a protection zone around feeding dishes of pets.

Customer Review(s)

5-year guarantee5-year guarantee

With their technical sophistication and excellent range of features, robots from myRobotcenter never fail to impress. Our robots are guaranteed to provide you with more free time and a better quality of life. Guarantee is also the key word when it comes the longevity of our products. Thanks to their sophisticated, tried and tested technology, our products have proven to be extremely reliable and free of faults. If a design fault should arise, then you can rely on a guarantee that – with many products – extends far beyond the statutory minimum.


Extension of the guarantee to 5 years

Our products come with a manufacturer's guarantee (generally 2 years). At myRobotcenter you get an even longer guarantee on many products: we extend the guarantee period to 5 years.


Complete security over many years

Our 5-year guarantee on labelled products is both a mark of quality and a very special service for you as our customer. In addition to the respective guarantee, we provide  you with all the details about the conditions of our guarantees and which services you can expect from us.


What does the guarantee cover?

The 5-year guarantee covers devices bought from us when accompanied by a receipt or another document that proves the validity of the 5-year guarantee. The 5-year guarantee ends five years after the device was purchased. The guarantee is valid for guarantee claims that occur in United Kingdom.


A guarantee claim is valid when the device purchased by you is damaged or destroyed, as a result of the following causes:

  • construction fault, calculation error, casting defect, material defect and production fault

  • direct effects of electrical energy as a result of a ground fault, short circuit, excessive increase in the current strength, electrical arc-over, formation of electrical arcs, insulation faults, excess voltage and the like.

Excluded from the guarantee is damage caused by external influences, such as a bounce flash in the circuit or fire damage. Such externally induced damages can be covered under certain circumstances by your household insurance and may include:

  • measuring, controlling and safety device failures

  • excessive pressure other than explosions

  • implosion and other effects of insufficient pressure

  • lack of water in steam boiler and other apparatus

  • bursts due to centrifugal force


Within the framework of the extended guarantee, operating errors are covered insofar as they impair the functionality of the product and do not represent a contravention of the operating instructions. For such cases we shall charge an excess of 84 GBP including VAT.


What is NOT covered by the guarantee?

  • Wear and tear, and damage to wearing parts and batteries (the battery is only covered by the manufacturer's guarantee)

  • Damage that does not impair the technical function of the device, e.g. scratches and scuffs.

  • Damage or destruction due to intentional or grossly negligent acts or omissions on the part of the purchaser or other users of the device.

  • Damage or destruction caused by improper installation/assembly, by improper repairs/adjustments, by improper, non-intended or unusual use or cleaning of the device – especially when the manufacturer’s instructions are not followed – and by operating errors.


What service do we provide in valid guarantee cases?

  1. When repair is technically and objectively possible and the costs of repair do not exceed the current value of the device (see clause 3), the device shall be repaired professionally and the costs incurred in the repair reimbursed by the guarantee.

  2. Should repair be technically or objectively impossible or uneconomical (total write-off), you shall receive a replacement device of the same kind and quality up to the amount of the current value (see clause 3). The damaged or destroyed device is returned to us and becomes our property.

  3. The current value of your device is 50% of the purchase price in the 3rd year after conclusion of purchase contract, 40% in the 4th year and 30% in the 5th year of the purchase price as stated in the receipt.


Is your device broken?

Just ask us for help. We will support you with the repair request.

  1. In the matters of a needed repair, a skilled and trained team in service and repair department from us or from the manufacturer itself, will gladly be there for you with advice and act to the side.

  2. Please take care of packing the robot carefully to avoid damage.

  3. Enclose a detailed description of the fault as well as the invoice together with the 5-year guarantee certificate.

  4. The robot must be fully postage paid at and sent to the mentioned address.

  5. Transport costs are paid by you and will not be refunded. We recommend that you keep the postage receipt.
