Which type of car wash should I choose? 4 types compared (prices and pros)
Self-service jet, automatic touchless, automatic with brushes, and a hand wash at the mall — prices, time, paint safety, and which one actually works at −10°C.
When it's time to wash the car, you really have four options: a self-service jet bay, an automatic touchless wash like RoboSpa, an automatic wash with brushes, or a hand wash at a detailing bay/mall. At first glance they only differ on price. In practice they differ on something far more important — what happens to your paint, how much time you lose, and whether it's even bearable in winter. Here's the honest comparison.
The four types, side by side

|---|---|---|---|---|
| Price | €5–6 | from €8 (~€8/wash on a plan) | ~€12 | €30–35, up to €50 if "very dirty", €60–70 with wax |

| Risk to mirrors, antennas, wipers | None | None — touchless | High — brushes snap and tear | None |
| Convenience | Stand in the cold and do it yourself | Sit warm, done in 3–6 min | Sit in your car | Leave the car for half a day |
The numbers are ballpark figures for the Sofia market, but the differences between the types hold everywhere. The cheapest isn't automatically the best, and the most expensive isn't automatically the safest. Let's go through each.
Self-service jet: cheap, but you pay in cold and time
The self-service jet is the cheapest option — €5–6 — and there's a reason for that: you are the labour. You grab the lance, walk around the car, switch programs, wipe it down by hand. It takes 15–20 minutes, and in winter it's genuinely miserable: you get wet, your hands go numb, the floor is slippery, and the water left on the car freezes before you can dry it. There's a hidden paint risk too — the self-service sponge or brush passes over dozens of cars and picks up grit and abrasive that you then rub straight into your own clear coat.
Automatic with brushes: fast, but your paint foots the bill
The gantry brush wash is fast (3–6 min) and cheap (~€12), but it cleans by friction. Rotating brushes press abrasive against the paint and, over time, leave a web of micro-scratches (swirl marks) that dull the colour. Worse — stiff brushes routinely break mirrors, snap antennas, and tear wipers when they catch a protruding part. We've laid out the mechanics in detail in touchless vs brush car washes. For a modern car with a clear coat, metallic paint, or a wrap, it's the wrong trade-off.
Hand wash at a mall: expensive, slow, and unpredictable
The detailing bay at the mall sounds premium, but it's the most expensive and slowest option. The base price is €30–35, but you leave the car for 2–3 hours. And the bill rarely stops there: if they decide the car is "very dirty", the price climbs toward €50, and once they offer wax you can easily reach €60–70. Quality depends entirely on who happens to be washing and how rushed they are. Sometimes it's excellent; sometimes it's the same mitt that just went over someone else's dusty car before you.
Automatic touchless: warm, fast, and safe for the paint
This is what we do at RoboSpa, and we deliberately chose this exact type. Touchless washing never touches the paint with anything hard — it cleans with chemistry and pressure. The cycle coats the car in active foam that breaks down the dirt, then water jets at 90–120 bar and 22 kW of power rinse it all away. The wash itself is done by 18 to 20 high-pressure jets — picture 18–20 handheld pressure washers covering the whole car at once, always spraying from a constant 35 cm. That's exactly why it's both safe and powerful: the pressure is high, but the distance is measured and nothing hard ever touches the clear coat. Finally, 33 kW of active drying, sides included, leaves the car dry — which is why it doesn't freeze in the cold. The whole thing takes 3–6 minutes, and you stay warm in your car the entire time.
The result: no swirl marks, no broken mirrors or antennas, no grit dragged across the paint, and a real price from €8 (or ~€8 per wash on a plan) — cheaper than the brush wash and far cheaper than the mall. Why we chose this equipment specifically is covered in how we chose our wash.
Why winter settles the argument
In the one season when your car carries the most salt and abrasive, every other option has a serious flaw. Self-service leaves you out in the cold, wet, with a freezing car. Brushes grind the winter abrasive straight into the paint. The mall is expensive and slow exactly when you want to wash often. The automatic touchless wash is the only one that washes often, fast, and safely — warm, at −10°C, without leaving the car. We've unpacked why frequency matters in winter in how often to wash the car in winter.
The bottom line
If you only count the price of a single wash, self-service wins. If you count the cost to your paint over ten years, the convenience, and winter — the automatic touchless wash is the only one that doesn't make you compromise. That's why every RoboSpa bay is touchless from the ground up.
