The brush is 25 cm (9.8 inches) wide, and its roller has a width of 21 cm (8.3 inches). That size is entirely sufficient for cleaning. We even reached the corners and got under most of our furniture. It sounds convenient, but I asked myself how its performance can be maintained over time if dust particles get permanently lodged in its fibers. Other Special Features And Ultimates We have little doubt Bosch has specified a lower torque brush bar motor to save power and increase runtime but – like the ineffective normal power mode – it’s a false economy. We would happily trade a couple of minutes of Turbo runtime for a brushbar that cleaned consistently without slowing or stopping. It’s not an issue we have experienced with Bosch’s premium competitors either. That alone lets down an otherwise excellent carpet-cleaning performance. The Dyson V15 has a single HEPA filter that is washable to extend the life and maintain the performance of the unit.

When it comes to suction, the Unlimited 7 proved to be a bit of a lightweight in our tests. A good vacuum cleaner isn’t only about the suction, but power in this regard certainly helps. On its most powerful setting, the vacuum only measured 11kPa. As you can see from our chart below, that’s only just over one-third of what a Dyson V15 Detect can manage (before it cuts out), and its similarly priced rivals are all more powerful even in low-power mode.Joe, our wireless vacuum expert on the Smart Home Fox team, has spent over half a decade meticulously testing every model that has landed with us. For one thing, you have to disassemble the device entirely whenever you want to empty the container because the individual parts are arranged that way. We would have expected a better system from the traditional company. The only disadvantage was that it pushed coarse dirt in front of the brush sometimes. That’s probably because the suction power is too strong for the brush’s narrow slot. The dust cup of the Dyson V15 has a capacity of 0.75 liters, while that of the Bosch Unlimited 8 can house up to 0.4 liters of dust and dirt. Aside from the small capacity, the other thing I don’t like about the Bosch Unlimited 8’s cup is that I had to disassemble the unit entirely to empty the container.

The Bosch came out with flying colours in our cleaning test thanks to the super-strong suction power . The cordless vacuum cleaner sometimes removed even more dirt from the carpets than we had spread on them.We could remove most dirt in the weaker mode. When it got really dirty, we made use of the turbo mode. The attachments’ contribution to the cleaning process The device sits nicely in the hand when vacuuming. The weight is well-distributed, so it’s not exhausting even if you clean for more extended periods. The Bosch brings 3.2 kg (7 lbs) to the scale. That’s a real heavyweight among cordless vacuums, and it shouldn't get much heavier.

The Bosch Unlimited has a size of 130 cm (51.2 inches) from top to bottom. That’s about the same as most other cordless vacuum cleaners on the market. Most people can vacuum comfortably with this size. We all know that taste is a matter of dispute. In our opinion, the new Bosch Unlimited Pro Power cordless vacuum has a futuristic design, but its focus is on pragmatism. The trend in the industry is three power modes. We were surprised when we found out that the Bosch has only two power settings. However, in our suction test, we saw that this doesn’t affect the cleaning performance. The handle is directly on the motor. That ensures a comfortable feeling when holding the vacuum cleaner.

The device also belongs to the Bosch series called "Power for all". All the appliances in this series use the same batteries, and you can swap the batteries between the devices. Where there is light, there is also shadow The bin itself takes a little getting used to as it releases from the cleaner by tipping forward and away. Emptying is as simple as pulling out the filter unit and tipping out the contents.
