Blend more, faster

Blend more, faster, with the Blendforce II Glass blender. The powerful 800W motor propels six Powelix Technology blades designed to amplify the mixing power for up to 30% faster* results. Three combined blade qualities guarantee the perfect mix: they're made of hardened stainless steel and set at an optimised cutting angle to ensure optimal resistance, even when tackling tough ingredients; they're razor-sharp to deliver optimal cutting performance for super-smooth results; and, when spinning, the blades create a powerful vortex to draw ingredients in, ensuring no chunks are missed for thorough blending and an even texture. From smoothies and soups, to dressings and dips, this heavy-duty food blender does it all. It can even crush ice with ease. A 2.0L capacity (1.25L working) means there'll be plenty to go around. Plus, because the jug is made of thermal shock-resistant glass, you can switch from hot (up to 80°C) to cold preparations in an instant. The built-in Air Cooling System optimises airflow through the motor to keep things cool, prevent overheating and extend the life of your blender. Meanwhile, the 3-in-1 Smart Lock makes it 40% easier to lock** the jug into place, secures the blades automatically, and allows safe and easy access to the blades for cleaning. Just unscrew the removable blade holder then pop it in the dishwasher, along with the jug and lid. Two simple speeds, plus pulse function, on the easy-grip rotary dial put you in full control, while four suction cups on the base keep the blender stable on your worktop.

  • Faster blending: Six Powelix Technology sharp stainless-steel blades provide the optimal resistance, cutting performance and vortex action to amplify the mixing power for up to 30% faster results.
  • Hot and cold: The thermal shock-resistant glass jug lets you go from blending hot ingredients (up to 80°C) to crushing ice without worry, while its 2.0L capacity (1.25L working) can handle large or small quantities.
  • Cool running: The built-in Air Cooling System optimises airflow through the motor to keep things cool, prevent overheating and extend the life of your blender.
  • Safety first: The 3-in-1 Smart Lock makes it 40% easier to lock* the jug into place, secures the blades automatically before running, and allows safe and easy access to the blades for cleaning.
  • Easy to use: The simple two-speed rotary dial, plus pulse function, makes it easy to get just the right texture. Four suction cups on the base keep the blender stable, no matter how tough the ingredients.

Frequent questions
The lid should always be in place while the appliance is in operation.
To add ingredients during mixing, remove the feeder cap and insert the ingredients through the filling hole in the lid.
If your appliance has this function, it allows you to make crushed ice, smoothies or frozen drinks by using the motor pulse function.
Always pour the liquid ingredients into the jug first before adding the solid ingredients, without exceeding the maximum level indicated.
For best results the food should be cut into cubes of 2 to 3 cm maximum before blending it.
No, do not put the bowl in a microwave oven.
Before using it for the first time, we recommend that you wash all the blender accessories in hot soapy water, taking care not to injure yourself with the blades, which are extremely sharp. It is not necessary to wash the body of the blender before use.
The chopper can be used for parsley, garlic, onions, bread, nuts, etc.
Use the "pulse" function for 2 second bursts each time, for a maximum period of 3 minutes.
Stop and leave the blender on pause for 15 minutes before restarting.
To clean the body of the appliance, first of all unplug it and then wipe it with a damp cloth.
To clean the bowl, use soapy water or washing-up liquid.
Some bowls are dishwasher safe, see instructions for use.
This is probably due to the fact that there is too much food, or that the pieces are too large or too hard. To correct this, reduce the size or the quantity of ingredients or add a little liquid.
The appliance may not be on a flat, stable surface, the appliance is not stable (foot missing, etc.).
The volume of ingredients to be blended is too high, reduce the quantity of ingredients.
If the vibrations persist, contact an approved repair centre.
Leak through lid (overflow):
• The volume of ingredients is too high, do not exceed the maximum filling level for the bowl as stated in the instructions for use.
• The lid is not correctly positioned, lock it securely on the mixer bowl.
If the lid has a seal, check its condition and change it if necessary.

Leak from the bottom of the bowl:
• Your appliance does not have a removable blade unit: the seal on your blade unit may be damaged, have it checked by an approved repair centre.
• If your appliance has a removable blade unit: check it is positioned correctly on the jug. You need to ensure that the black notches on the blade unit are fitted fully into the equivalent recesses on the base of the jug – this will be apparent if you cannot turn the blade unit any further and if you turn the jug upside down you should not be able to see any gaps between the jug and the blade unit.

• Check that the gasket/seal is positioned the correct way around on the blade unit - the 3 folds of the gasket/seal must be visible once it is in place. If it is positioned in the other direction, you will not be able to lock the blade unit on the jug.

• Check the condition of the seal/gasket and change it if necessary.
• Check that your bowl is not split or broken as a result of impact.

If the leak persists, take the appliance to an approved repair centre.
After following the instructions in the user manual for starting the appliance, make sure that your electrical socket is working by plugging another appliance. If it still does not work, do not try to dismantle or repair the appliance yourself, instead, take it to an approved repair centre
Do not use your appliance. To avoid any danger, have it replaced by an approved repair centre.
Your appliance contains valuable materials which can be recovered or recycled. Leave it at a local civic waste collection point.
