Why professionals choose it
The Hydramaster Boxxer 318HP is an economically priced, high-value, high-performance carpet cleaning and high-pressure hard surface cleaning machine.
With an 18-horsepower engine and a 315 CFM vacuum blower, this machine is powerful enough to run over 90 meters of vacuum hose – and it delivers enough heat to clean dirty carpets all day long. Plus with a 1500psi heated solution, it cleans tile grout, and other hard surfaces with ease. The 318HP is a machine that the new business or one moving up from a portable, won’t outgrow any time soon.

Where the decision sits. Airflow determines drying time and how far you can run hose. Pump pressure matters for hard surface work — around 1,000 psi is enough to clean tile and grout, so every machine here is capable of it, and higher pressure gives more margin on heavily soiled or textured surfaces. Solution temperature does the cleaning, and a liquid-cooled engine sustains it under continuous load where air-cooled tapers.
On size and weight. Published console dimensions and weights are not measured consistently between models and do not always match the machines as supplied here. Tell us your vehicle and we will confirm the actual figures before you order.
Engine, blower, pump and temperature figures are from HydraMaster’s published documentation. The IN THE BOX package on this page is what Carpet Cleaners Warehouse supplies and differs from HydraMaster’s standard equipment list — ours applies to your order.
What else you will need
- RX20 NEXTGEN rotary extractor — rotary extraction for commercial carpet, driven from the truckmount
- Automatic Wastewater Disposal System — pumps waste to an on-site sanitary connection instead of returning to dump
- Hose, wands and hard surface tools to suit the work — ask us to spec a kit against the machine
Warranty
The Briggs & Stratton Vanguard engine carries a 3 year warranty. Other components vary. This does not exclude, restrict or modify your rights under the Australian Consumer Law. Our goods come with guarantees that cannot be excluded under the ACL. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.

Frequently asked questions
Is the package the same as HydraMaster’s standard equipment list?
No. The IN THE BOX list on this page is what we supply in Australia, and it differs from the manufacturer’s standard equipment — hose lengths and tools in particular. Where the two disagree, ours applies. Ask us for written confirmation before ordering if it matters.
What vehicle do I need, and what does the machine weigh?
Ask us. Published dimensions and weights are not measured the same way between models — some are console only, some include the frame — and they do not always match the machines as supplied here. Tell us your vehicle and we will confirm the actual figures.
Who installs it?
We do, or an authorised representative by prior arrangement. Installation covers mounting, exhaust routing, plumbing and electrical, and it is not a job to hand to a general workshop.
There are warranty ramifications if it is installed incorrectly. A machine damaged by a poor installation is not a warranty claim, so arrange the install with us before the machine arrives rather than after.
Does higher pressure mean better cleaning?
Not on carpet. Carpet cleaning happens at relatively low pressure with heat and dwell doing the work. On hard surface, around 1,000 psi is enough to clean tile and grout — higher pressure gives more margin on heavily soiled or textured surfaces and lets you work faster, but it is not what makes the job possible.
Why does airflow matter more than it looks?
CFM at the machine sets recovery at the wand, and recovery sets drying time. It also determines how far you can run hose before performance falls away, which on multi-storey or long-run commercial work decides whether the job is practical.
What warranty applies?
Manufacturer warranty terms vary by component — the 575HP Kubota engine carries a 3 year manufacturer warranty, for example. This does not exclude, restrict or modify your rights under the Australian Consumer Law. Our goods come with guarantees that cannot be excluded under the ACL. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.
