Read the specification as three separate lists
Installation figures hide inside a mixed table. Split them before comparing two machines:
- Site services: supply voltage, the power the machine actually draws when heating, whether a battery is included or optional, and what charging needs.
- Consumables and connections: water inlet type and fitting, tank capacity, water quality expectations, and any gas or extraction the process requires.
- Physical envelope: dimensions including handles and hoses, weight when filled, and the smallest door, ramp or lift the machine has to pass.
Check the electrical claim against your supply, not your socket
Heating power and supply voltage are usually published; the circuit protection, cable length and socket rating that go with them are not. Ask three questions of every figure you read: is this the machine's rating or the measured draw; does the stated voltage assume a single phase and a specific supply; and what protection and cable does the manufacturer expect between the panel and the machine?
Then verify at the actual location. Walk to the point where the machine will be used, find the nearest suitable outlet, and have an electrician confirm the circuit can carry the heating load continuously rather than briefly. Long extension leads are where steam machines fail in practice: voltage drop lengthens heat-up and trips protection, and an outdoor or wet environment needs appropriately rated cable and protection.
Verify water, drainage and the practical envelope
Tank capacity is easy to read; the refill cycle is not. Check how long a full tank runs under your duty, where it is refilled, and what fitting the inlet expects — a published inlet description tells you whether you need an adapter before the machine arrives.
For water quality, ask the manufacturer what they specify and what they have seen fail. Scale is a maintenance cost, not a warranty item, and a published figure that a machine “runs on tap water” does not tell you what it does to the heater over a year in a hard-water plant.
For the physical side, measure your route, not your room: door widths, the lift, floor slopes, and the farthest point the hose must reach. Take the published dimensions including handles and check them against the narrowest point on that route. And confirm where the loosened residue and condensate go — a machine with no recovery path turns a cleaning job into a spill.
Ask for the missing numbers in writing
Most product tables omit the figures that actually decide the purchase. Before ordering, ask the supplier to state: continuous current draw during heating and the recommended circuit protection; realistic runtime per tank at your duty; charge time and runtime for battery models; the inlet fitting and the water quality they recommend; the noise level if the machine runs near occupied areas; and the dimensions with hoses fitted.
A supplier who answers those questions in writing is a supplier whose installation figures you can plan around. A supplier who does not is asking you to find out on the delivery day. On our own listings we note explicitly which parameters are published on the product page and which are not — if a figure is absent, ask, and get the answer before the machine is ordered rather than an excuse afterwards.
Prove it with one installed machine, not on paper
The final verification is a trial on your own floor, with your water, your supply and your residue. Set it up at the farthest point of use, run it until the tank needs refilling, and time the whole cycle including refilling, moving and drying. That figure — not the specification — is the number to put into the business case.
Send us your site conditions — supply at the point of use, water point and fitting, floor route and door widths, and what you are cleaning — and we will confirm which of our published specifications apply to that situation, which figures you should treat as unconfirmed, and what we would need to see to recommend a fixed, hand-pushed or driving-style unit.
