Sell Your Used Pressure Washer — 0% Fees

A used pressure washer typically sells for £40 to £200, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Pressure washers sell on pressure and on whether the pump still holds it — and the accessories, especially the lance and hose, are worth more of the price than sellers expect.

The short version

Typical range: £40 – £200 — see the full pressure washer value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Run it and check it builds and holds pressure without pulsing, which is the classic sign of a tired pump.
Check the hose along its length for splits and the fittings for leaks.
Gather every lance, nozzle, brush and detergent bottle, and note the model.

The photographs that sell a pressure washer

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The machine whole, with hose and lance attached
All accessories laid out together
The pump housing and the model plate
The hose fittings and trigger gun, plus any crack, leak or perished seal

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Brand, pressure and accessories: “Karcher K4 Pressure Washer with Patio Cleaner and 2 Lances”. Model number is the search on the main brands, and accessories are model specific so listing them by name genuinely adds value.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Brand, model, and maximum pressure in bar or PSI
Flow rate if stated, and whether it is induction or universal motor
Every accessory included, named
That it has been run and holds pressure, plus any leak or fault

What buyers will actually ask

You will receive the same three messages about a pressure washer. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“Does it hold pressure?”

Run it and watch for pulsing or a drop. Pump failure is the main reason pressure washers get replaced and buyers know to ask.

“Which accessories are included?”

Name each one. Patio cleaners and specialist lances cost a lot separately and are model specific, so they lift the price meaningfully.

“Is the hose split?”

Run it through your hands and check the fittings. Hoses perish where they kink and a split hose loses pressure at exactly the wrong moment.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The pressure washer value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £120 sale — roughly the middle of the range for a pressure washer — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£120
Poshmark	−£24	£96
eBay	−£16	£104
Mercari	−£12	£108
Etsy	−£8	£112

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Strongly seasonal, from March to August with a spring peak. A working machine listed in April sells within days; the same one in November will sit.

Drain it completely before transport or storage, especially in cold weather, since trapped water can crack a pump if it freezes. Heavy for its size, so weigh before quoting postage.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used pressure washer worth?

Typically £40 to £200, with induction-motor models and full accessory sets above. See the pressure washer value guide for the bands.

Why do pressure washers stop building pressure?

Usually a worn pump seal, a blocked nozzle or a leaking connection. Say honestly what yours does — a machine that pulses should be described as faulty rather than as working.

Should I drain it before selling?

Yes, always before transport and before winter storage. Water left in the pump can freeze and crack the housing, which turns a working machine into scrap.
