Bosch is a household name for high-end appliances, starting with Dishwashers to Refrigeratorsbut it is not well known Cordless vacuums. The brand recently showed me the new Bosch Unlimited 9 and Unlimited 10, its new cordless vacuums, before Consumer Electronics Show 2026. These new models are packed with features that could give them a formidable competition Dyson and sharkthe two companies that have dominated the industry for years now.
I spent about an hour testing both models at Bosch, Thermador and Gaggenau’s Experience and Design Center in New York. Here are my thoughts on the Unlimited 9 ($499 to $579) and Unlimited 10 ($599 to $699), which should be available starting in January during CES.
I spent some time testing both the Unlimited 9 and 10 and the auto-sensor seems to do a good job of detecting clutter.
Dyson’s standout competitor?
The feature that immediately caught my attention in Unlimited 9 and Unlimited 10 was the same one that impressed me when I tried Dyson V16 Animal Piston – Dust compactor trash can lifter that allows you to compact debris and remove it more easily into the trash can. This feature is available on both models, and the implementation is basically the same as what I tested on the Dyson Piston Animal.
It was able to vacuum up a wide range of dirt and debris in the Bosch showroom, from sample carpet tiles and hardwood floors. I can then quickly and efficiently empty everything into the bin with the push of a button, without the usual shaking and pulling of dust. You can also compact the trash while vacuuming to make more space when it’s full. I recommend doing this, as it improves airflow and capture efficiency.
Both the Unlimited 10 and 9 have a lever that compresses the trash can for easy removal and space saving.
Another notable feature of both models is the automatic suction adjustment, also known as Auto mode. This is a common feature available in many vacuum cleaners today. You’ll find it in Piston Animal and more affordable cordless vacuums like the Eureka ReactiSense 440, our best overall pick for cordless vacuums. The idea behind this is simple and time-saving: Instead of having to switch suction up and down to clean different surfaces, like hardwood, tile, and carpet, the vacuum handles that chore for you.
I found both the Unlimited 9 and 10 to be fairly responsive at recognizing new surfaces, automatically increasing suction when moving from hard floors to carpet or when a messier area is detected. You can still change models manually using the controls and display with Eco mode, Auto mode and Turbo mode, which will have the expected impact on battery life.
The only downside I noticed to both models is that they don’t seem to stand on their own, which is a simple but often overlooked feature that I find convenient in cordless vacuums. There’s also no self-discharging charging station, which is another feature I enjoyed in the models I tested, e.g Leavewit Aero.
The Unlimited 10 comes with a HEPA filter and an anti-tangle brush.
Microscopic dust rags
Both the Unlimited 9 and Unlimited 10 come with a “Micro Clean Sensor,” which is an LED ring around the vacuum’s display that lights up in different colors to let you know how clean your floors are.
Gray or dark indicates a very dirty surface, white indicates a fairly clean surface, and blue indicates a microscopically clean surface. Bosch says the vacuum cleaner is capable of removing even microscopic dust particles. I’ll reserve judgment on that until our lab team in Louisville has a chance to test it.
As a simple quality of life benefit, it’s a nice touch. Assuming the sensor is accurate, you should be able to tell if your floors are clean at a quick glance.
The Unlimited 10 has a TFT display and a sensor ring that can detect how clean your floors are.
Unlimited 9 vs. Unlimited 10: Battery life and accessories
Bosch differentiates between the Unlimited 9 and 10 in several ways. The biggest differences between the two models come down to battery life.
The Unlimited 10 comes with a 4-ampere-hour (Ah) battery that Bosch says should last 80 minutes in handheld mode, 65 minutes in Eco mode, 25 minutes in Auto mode, and 11 minutes in Turbo mode.
With the Unlimited 9, you’re looking at a smaller 3Ah battery that should last 60 minutes in Manual mode, 50 minutes in Eco mode, 17 minutes in Auto mode, and 10 minutes in Tubo mode.
I tend to take self-reported battery life times with a grain of salt, as they are measured using only the nozzle rather than the brush tip. I’ve seen significant differences between the battery life the company claims and what I, as one of our employees, experienced in real life Recent laboratory reports open.
On the plus side, Bosch says there will be a fast charger to allow for faster charging times of between 50 and 60 minutes, depending on the model. They will also offer bundles with an additional battery pack.
Both models come with plenty of accessories, but only the Unlimited 10 has the flexible attachment.
Other differences between the models are minor. The Unlimited 10 has a nicer TFT screen that provides more functional information, while the Unlimited 9 has a standard LCD screen. The Unlimited 10 also comes with a flexible tube that allows it to bend to fit under sofas and low furniture, an attachment we’ve seen on several Shark vacuum models. Both models have an anti-tangle brush and a HEPA filter.
Now, can Bosch give Dyson and Shark a run for their money? That remains to be seen, but at $599, with features that match the V16 Piston Animal, it’s certainly priced right to do so. And the $499 Unlimited 9 is on par with the Shark Stratos. We’ll be testing both models in CNET’s Vacuum Test Lab when they’re available, so we expect to have more comprehensive testing results soon.
