Bosch BCS122GB Unlimited Serie | 8 - Rechargeable Cordless and Lightweight Vacuum Cleaner for Multiple Surfaces with Two Interchangeable Power For All Battery Packs and Quick Charger,White

Product Information

Close-to-edge cleaning was very impressive, and even close up, the Turbo mode delivered a decent clean in just this single run. It took a couple of passes to get rid of all the heavier carpet powder particles, but the good suction did well in one pass. The Bosch has two power levels, normal and Turbo. To summarise, let’s call these settings ‘poor’ and ‘properly effective’ respectively. With these standard tests, we aim to compare different vacuum cleaners and offer you the best possible advice. 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.

Thankfully, because of the two batteries, this Bosch delivers plenty of serious Turbo-mode cleaning runtime. With the fast charger taking 55 minutes, power is not quite unlimited, but you can get a very long way around the house in 18 minutes. Bosch Unlimited BCS122GB – How noisy is it?

The Bosch Unlimited 7 gets many things right, but doesn’t keep pace with the latest cordless stick developments

Except, in fact, you can: the Vax ONEPWR Blade 5 Dual Pet & Car comes with all the attachments you might need and a second battery. While those batteries don’t last as long as the Bosch’s, its soft roller helped it perform better in our all-round cleaning tests. 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.

We first saw this tech on some of Bosch’s mains-powered cleaners and it worked well for both filtration and reducing the filter cleaning chore. It’s not washable though, so we do wonder how its performance will fair over time when particles get permanently lodged in its fibres. At 65dB, the BCS122GB competes with some of the market’s best low-noise and ‘silence’ mains cleaners. You won’t disturb the neighbours even during midnight cleaning sorties.We would have much rather seen the normal mode offer twice the suction and half the runtime. That would give you about half an hour of ‘normal’ cleaning with the floorhead per battery. As it is, with its two batteries, the Unlimited BCS122GB offers over two hours of not very much at all on normal mode. An essential advantage of cordless vacuum cleaners is the "2-in-1 function". It increases versatility in use enormously. Now you can also use it to clean your car. The configuration of the Bosch Unlimited will be familiar to most people by now; if you’ve seen a Dyson V8, you know the deal. The vacuum motor, battery and dust collection bin are all housed in a compact, handheld unit that you connect your cleaning attachments to. When emptying the dirt container, it’s crucial that you can carry the dirt from the device to the dustbin as easily and as cleanly as possible. Every manufacturer has its own system. Some work well, and others don’t.
