The short version
What you need to know.
- A$3,299 at Dreame Australia; its own store was sold out when checked.
- 180°C is the boiler-outlet figure; the stated nozzle temperature is 100°C.
- 10 cm describes a qualifying two-step arrangement; the single-step claim is 5 cm.
A premium robot, with specific promises
A robot that can deal with sticky kitchen mess and cross a difficult doorway would be useful. A robot that requires you to rearrange the house before every clean is rather less relaxing. That is why I’d spend a few minutes with the measurements before buying Dreame’s Aqua20 Ultra Roller.
Its Australian launch was announced on 1 October. On 21 October, Dreame’s own store lists the black model at A$3,299 and marks it sold out. That describes the manufacturer’s store, not every Australian retailer. Check stock and the actual offer wherever you plan to buy.
This is a document-based buying check. I have not tested the Aqua20’s cleaning, climbing or floor compatibility, and the headline numbers should not be read as independent results from Compare.
Where is the steam actually 180°C?
The Australian product-page remarks say 180°C is measured at the steam-generator boiler outlet. The stated temperature at the robot’s steam nozzle is 100°C. Neither number establishes a constant temperature across your floor during a cleaning pass.
That distinction matters when deciding whether steam suits the surface you own. I’d check the flooring manufacturer’s cleaning instructions and the robot’s permitted use before assuming a hotter headline is automatically better. Expensive flooring is a fairly unpleasant place to discover that compatibility had an asterisk.
Dreame also qualifies its bacteria-removal result. Its description concerns specified bacteria introduced into the clean-water box, with steam condensate sampled after five minutes. That is a laboratory result reported by the brand, not proof that the robot sanitises every part of an ordinary kitchen floor.
Ten centimetres is a two-step claim
The 10 cm obstacle figure applies to a double-layer step where the lower step’s top surface is more than 24 cm wide. Dreame lists 5 cm for a single-layer step. A single 10 cm doorway lip is therefore outside what that headline describes.
Measure the height, depth and shape of the transitions that matter in your home. Photographs with a ruler are more useful than telling a salesperson the doorway is “a bit chunky”. Ask about the actual surface and approach, too, because a lab specification is not a guarantee for every threshold.
The mop-extension number needs similar care: 8 cm is the movement from retracted to extended, while the mop reaches up to 4 cm beyond the robot body. It does not promise an 8 cm reach underneath every cabinet.
The useful question is how it cleans your house
There are operating limits beyond the measurements. Dreame says steam cleaning and roller extension cannot be activated together. Its page also says Room-mode steam cleaning will come through a future over-the-air update. I would check which modes are available on the unit and firmware being sold, rather than buying on a promised update alone.
Before spending A$3,299, I’d map the floors, thresholds and awkward edges that actually cause work. Then ask about replacement rollers and filters, water-tank upkeep, dock clearance and the return policy if the documented climbing arrangement does not suit the house.
My take: the Aqua20 has an interesting approach to mopping, but its claims are more useful once the conditions are attached. Compare it with alternatives in our robot-vacuum finder, and prioritise the jobs it needs to do reliably. You’re buying help with the cleaning, not a collection of very warm numbers.
