Series 3S Touchless Car Wash with Side Blowers for Unattended Sites

The Series 3S from HeyCar is a touchless car wash with side blowers for sites where nobody wipes the car.

It takes the Series 3 and adds two 5.5 kW side air blowers aimed at doors, side panels and mirrors.

As a result, cars leave with fewer water spots on the surfaces drivers look at first.

The problem side blowers solve

Top fans push air down onto the roof, bonnet and boot. That is where most water sits.

However, vertical surfaces get far less airflow from above.

Water runs down the doors, collects around mirror housings and then dries as spots.

On a staffed site, an employee wipes those areas with a towel before the car leaves.

On an unattended 24-hour site, there is no employee, so the driver sees the drips.

That first impression decides whether the customer comes back next week.

So the side blowers target exactly the panels that top fans leave wet.

Why a touchless car wash with side blowers suits unattended sites

The Series 3S runs 24 hours unattended, and customers can scan a QR code to start a wash.

In that setup, the machine has to finish the job alone, because no staff member steps in.

Two side blowers cut the manual wiping that a top-only dryer still needs.

Therefore, gas stations, residential car parks and self-service lots get a cleaner exit result.

Fewer spotty mirrors also mean fewer complaints from drivers at night.

In addition, optional app remote monitoring lets you watch the site without being there.

Mirrors and doors: where drivers judge the wash

Drivers check their side mirrors as soon as they pull out of the bay.

A wet or streaky mirror is also a visibility issue, especially in rain or at night.

Door glass and door handles are the next places drivers notice drips.

The 5.5 kW side blowers aim at these zones while the top fans dry the roof.

Be realistic, though. HeyCar states that automatic machines still have dead spots.

For example, wheel hubs, door handles and mirror edges can still need a quick touch-up.

The side blowers reduce that work, but they do not remove it completely.

How the wash and dry cycle runs

1. Profile. Pepperl+Fuchs photoelectric sensors read the vehicle silhouette before the arm moves.
2. Chassis rinse. 16 underchassis sprayers clear road salt and grime from below.
3. Pre-soak. The machine sprays shampoo automatically, at 20–40 ml per car.
4. High-pressure wash. The 360° arm rinses at 60 kg / 853 PSI through 15 nozzles.
5. Water wax. A wax coat helps water bead and roll off the paint.
6. Top and side drying. The 16 kW top dryer works together with the two side blowers.

The full program takes 6 to 8 minutes, depending on the settings you choose.

Key specifications

Site requirements and running costs

The 3S needs the same minimum space as the Series 3: 6.5 × 3.5 × 3 m.

So you can plan the bay first and decide on side blowers later in the quotation.

The machine runs on 3-phase 380V or 220V power at 50 Hz or 60 Hz.

The side blowers add electrical load, so HeyCar confirms the total power in your quotation.

Per car, the published figures are 60–80 litres of water, 0.8 kWh and 20–40 ml of shampoo.

Moreover, the optional water recycling system saves more than 85% of water.

Series 3S compared with Series 3 and Series 5S

Choose the Series 3 if staff hand-finish every car anyway.

In that case, the top dryer is enough, and you keep the lower machine cost.

Choose the 3S when the site runs unattended but your volume is moderate.

Then step up to the Series 5S for heavy 24/7 traffic.

It adds a German Perfect Power pump at 80 kg, a Mitsubishi PLC and a free vacuum.

Moreover, it needs a larger bay of 7 × 4 × 3.2 m.

Frequently asked questions

Is a touchless car wash with side blowers worth it over the Series 3?

Yes, if your site runs unattended. If staff wipe every car, the Series 3 is usually enough.

Does the 3S need a bigger bay than the Series 3?

No. Both use the same minimum installation space of 6.5 × 3.5 × 3 m.

Will mirrors come out completely dry?

Mostly drier, but not always perfect. Mirror edges and door handles can still need a touch-up.
