Two Bosches — the green home range and the blue professional one, with very different specification habits
Bosch sells into this niche twice. The green home and garden range covers the UniversalAquatak pressure washers and the UniversalVac vacuums; the blue professional range covers machines like the GAS 12-25 PL. They are different products with different documentation, sold side by side.
Sensibly designed and quietly specified. The 3-in-1 nozzle on the UniversalAquatak machines is genuinely practical — fan, rotary and pencil jets in one head, so the lance you need is never in the shed. What the listings do not give is a flow rate, which makes honest comparison with a Kärcher or Nilfisk impossible on the number that decides cleaning speed.
The opposite. The GAS 12-25 PL publishes 65 l/s of airflow and 200 mbar of suction on the same line — the pair that actually describes a vacuum, and which almost nobody else prints. If you want to compare machines rather than believe them, that is where to start.
Bosch uses its own connector on domestic washers. The AquaSurf surface cleaners list the exact machines they fit, which removes the most common wasted purchase in this category.
140 bar · 450 l/h · 2,100 W · integrated storage
The Bosch that finally publishes a flow rate — 450 l/h, which is what the UniversalAquatak machines never gave you.
Best for: A drive, a terrace and vehicles, for someone already inside the Bosch accessory system
280 mm (11 in) · swivel joint · for Bosch AQT and Aquatak machines
Bosch's own surface cleaner, and the fitting list on the box is the specification that matters.
Best for: Owners of Bosch UniversalAquatak, AdvancedAquatak or AQT machines with a patio to clean
Up to 35 windows per charge · LED battery indicator · streak-free
Bosch quotes its runtime in windows rather than minutes — which is the number you actually wanted.
Best for: Households already using Bosch home tools, and anyone who wants a runtime figure they can act on
≈ $100
125 bar · 3-in-1 nozzle · 5 m (16 ft) hose
The cheapest machine here, and the one whose single nozzle does the work of three.
Best for: A first pressure washer for a small garden, a bike and a car, where price decides
135 bar · 3-in-1 nozzle · 7 m (23 ft) hose
The 125 with ten more bar and two more meters of hose — and the second of those is the one you notice.
Best for: A drive, a terrace and a car — the general-purpose choice where the 125's hose would be the limiting factor
1,000 W · 15 l · five paper bags included
The small, cheap, sensible one — and the bags in the box are most of the value.
Best for: A flat, a car and light workshop use, where storage space decides more than capacity
