Do I Need a Generator for Mobile Detailing?

If you need to pump water, power polishers, or run a medium to big detailing business, you’ll need a generator.

Remember that a good generator is not cheap. If you’re just starting off, you might not want to invest $800-$2000 unless absolutely necessary. It is likely to be more cost-effective to purchase extension cords and hoses if you are going to your client’s home and the customer has access to both water and power.

However, having a generator has advantages such as powering vacuums and pumps, pressure washers, and everything else of a mobile detailing tools setup.

The first step is to make a list of all the devices that will require electricity. This will assist you in determining what type of generator is best for your business.

What Mobile Car Detailing Tools Professional Detailers Use that Require a Generator?

  • Shop-Vac: A wet or dry vacuum cleaners that can pick up both liquids and dry dirt and debris is required.
  • Air Compressor: An air compressor may be required for your buffers. If you run a mobile detailing business and employ an air compressor-type wash system, you’ll also need an air compressor.
  • Dual Action Polisher: The most commonly utilized tool for mobile auto detailing is a dual action polisher. Any detailer will tell you that utilizing a Dual Action (DA) polisher saves time.
  • Detailing Steamer: A steamer is a versatile detailing tool that may be used for a variety of purposes. It disinfects and cleans headliners, panels, and cup holders.
  • Ozone Generator: While not required, an ozone generator may be a valuable piece of car detailing equipment. When connected to the dashboard, it may permanently eradicate scents such as smoke in a matter of hours.
  • Detailing Air Blower: Cheap air; all you need is electricity and an extension cable.

What Size Generator Do I Need for Mobile Detailing?

Because generators vary in a range of sizes and types, it’s necessary to choose one that will meet your demands.

For many people, the main reason to buy a generator is to power their vacuums and pressure washers. Here are some other common uses:

ToolsRunning Watts (W)
Powering electric pressure washers1620W
Powering Polishers500W
Powering vacuums and Shop-Vacs1500W
Powering Air Compressor1500W
Powering Steam Cleaner1000W
Powering dual action polisher500W

As the table shows, even the 2000W generator is enough to power all of these tools. In spite of this, we continue to suggest that you go with a generator that has a little bit more power.

What Type of Generator for Mobile Detailing?

First, you need to know the sorts of generators. we’ll here the two sorts solely that can help an auto detailer.

Consider the following two types of generators:

Inverter Generator: The best generator for car detailers is an inverter generator. They may not always work at 100% efficiency. They only produce power to the extent that the plugged-in tools can be powered. As a result of their efficiency, you’ll save money on gas. They’re also noticeably quieter.

Conventional Generators: While inverter generators offer higher output at a lower price, conventional or traditional generators often deliver more watts for the same investment. However, they are less fuel-efficient as they work at the same pace all the time. They’re also noisier and larger than inverter generators.

Things to Know Before Buying Best Generator for Car Detailing

Before everything, there are several things that you should comprehend. That’ll assist you a lot when picking the correct size generator for your auto detailing business:

Continuous power: the power that a generator can produce at any time. It would be best to choose a generator with a wattage that is slightly higher than the tool you run with it.

Peak Wattage: means how many watts a generator can produce in a short period of time. Its always a bit higher than the power that a generator can supply continuously. It’s important because some tools may require more power at peak times than a constant power supply. Most tools require more power when you are just starting them up.

Watts (W): a unit used to measure the power produced or consumed by a device. It is important because you need to know the right wattage to operate a specific tool.

Ampere (A): the unit for measuring the electric current.

Voltage (V): the difference in the current between two points. Appliances in the USA typically run on 110-120 volts, and in Europe, it’s 220-230 volts.

Most electric devices have all the voltage, watts and amps are listed in the device description. Sometimes, you might not see watts on some tools. So, you need to know how to find the wattage required for a specific device.

Watts are calculated by multiplying amps by voltages. So, if you want to calculate the power that you need, you need to know the Amps and the Voltage numbers.

Best Portable Generators for Mobile Detailing – Buying Guide

There are some things you should keep in mind when you are buying a generator. Make sure that the generator you want is small and portable, and that it is efficient. Look into the other features that your generator comes with. Powerful generators may seem like a good idea, but they are large and bulky when you want to move them around.

Weight and Size

When selecting the best generator for detailing, check that all your choices are lightweight and easy to move about. Because you’ll be driving to your client’s location, you’ll want a generator that won’t take up too much room in your car or truck.

A tiny, compact generator is great for attaching vacuums, but if you have a team of 2 to 3 persons working concurrently on the interior and outside, you might require a larger wattage inverter generator. We suggest getting two compact, lightweight generators that can be connected in parallel instead of one big one.


You may also want to consider the size of the fuel tank you use, as it will affect the efficiency of your generator. If you run a gas-powered generator, it is likely that you will quickly run out of fuel, more so than a generator that runs on either liquid propane or gasoline. Typical inverter generators are very small and will only be able to run for 4 to 5 hours.

Larger models with more horsepower have a bigger fuel tank so they can run for longer periods – up to 10 hours! Inverters are better because they automatically adjust engine speeds, when necessary, thanks to their microprocessor technology. Inverter generators detect when a generator is needed and use fuel efficiently to reduce fuel waste.

Noise level

Generators that are extremely loud can generate noises ranging from 60 to 80 decibels.

When detailing cars for your clients, the last thing you want to do is to completely block their conversations and make them feel lonely.

It is important to look for a generator that does not produce a lot of noise. That could cause your customers to feel disturbed or irritated while you are working on their cars.

Buying a generator that runs on propane will be a lot quieter and more eco-friendly than a gas-powered generator. Generators that use inverters are more efficient than standard generators, so they last longer and generate less noise.

Other features such as sound damping technology or pulse technology can help reduce the noise level of your generator.

Additional Features

If you plan to use a generator to clean cars, you should look for one that is portable. It may be useful if the generator comes with a power adapter, a magnetic oil dipstick or a connection kit for different portable power sources. Do you have simple knobs that allow you to quickly switch between different controls?

It can be useful to have a generator that has an extension cord that is quite long, allowing you to move the generator around more easily. Look for a generator that is lightweight and easy to move around with its large wheels or handles to make it easy to transport it when you are moving from place to place.

Some generators have special LED indicators that let you know how much fuel is left in the tank or on the engine. These additional features can help you to more efficiently handle your detailing jobs.

Best Generators for Mobile Detailing: FAQs

What kind of generator do I need to run a pressure washer?

If you are planning on using a portable generator to run an electric pressure washer, then keep these things in mind. It will take around 1,200 watts to power a pressure washer with a 1.5 hp motor and it can take up to 3,000 watts to run it on a surge. You would need to have a generator that can handle a big surge like that.

What size generator do I need to run a shopvac?

You could use a 1.5 hp vac to do some really nice vacuuming. A shop vac needs at least 1000w per hour and a peak power of about 1500 watts per hour when it is turned on.

Can you run a pressure washer off an inverter?

You will need a 5000w inverter to run power tools like pressure washers and polishers. Inverters that produce more than 1500w need a very serious power source and are therefore normally connected to a small battery or a leisure battery. Better you use a portable power station mentioned above.

Who makes the quietest generator?

If you know anything about generators, then you know that Honda makes one of the quietest portable generators that you will find.

What is better inverter or generator for detailing work?

Inverters are excellent because they generate extremely high-quality (pure sign wave), stable power output. It is pretty obvious that inverters are expensive and without high wattage power inverters you can’t power you detailing equipment. Generators on the other hand can produce enough power on their own and there are inverter options too.

Why are Honda generators so good?

You can trust that Honda generators will work reliably for a long time. Using fuel-efficient equipment means saving money and reducing emissions. Honda machines are built to last and will last a long time.

Do you need a compressor for detailing?

Air cleaning is also useful for cleaning microfiber pads that get clogged up with wax or other products when you are doing some exterior detailing work. While it is important to wash those pads with soap and water after using them a lot, using compressed air is a great way to keep them soft and clean.

Is a detailing business profitable?

Some people estimate that they can easily make up to $90,000 per year running a one-person detailing business. This is based on doing three jobs per day for a period of five days and charging $120 per job. According to a report by the Houston Chronicle, starting a self-service car wash can bring in as much as $100,000 per year and running a full-service business can mean as much as $900,000 per year.

What type of water tank do you need for detailing?

For mobile detailers, a portable water tank is an essential part of their supplies. Some people think that smaller tanks hold 60 gallons of water, but a big tank can hold 200 gallons of water.


We hope you’ve found this guide to the best generators for mobile detailing useful. As a mobile detailing professional, your goal should be to buy a small, lightweight, portable but efficient generator that will last all day as you hop from one job to the next.

If you are a new mobile detailer and just starting out on a low budget, we recommend you opt for a small inverter generator like a 2000watt, that is lightweight enough not to be a burden and later you can increase the capacity by paralleling. 

If you’re specialist car detailer an work on both interior and exterior detailing and need more power, we’d recommend something bigger than 6500 watts. Since most detailers leave their generators running in an open trailer, weight becomes less of a factor.
