Corded vs Cordless Polisher: Which One Should You Buy?

Corded vs cordless polisher: side by side

Specifications are manufacturer rated, as published on each listing and collected 19 October 2026.

Power: corded watts vs battery platform

The corded side states its power plainly. The AUTIWOZ lists a 630W pure copper motor and claims 37% more power than common 380W models; the Milwaukee lists 1200W maximum power on its 18V platform. The CRAFTSMAN corded listing is thinner, 2800 OPM on a 10 in pad, with a 1 A and 230V table entry that looks off for a US tool. Do not call either side more powerful on these figures: a corded watt and a battery platform’s maximum watt are different measurements from different listings.

Pad size and the job

Pad size decides the job. The AUTIWOZ is a mini, 2 and 3 in backing plates for A-pillars, door handles and headlights, with 3000-grit sandpaper in the kit for spot work. The CRAFTSMAN examples, corded and cordless alike, are 10 in orbitals for large surface coverage. The Milwaukee sits in the middle at 7 in. Match the pad to the panel: minis for details, 10 in for hoods and roofs, 7 in as the all-rounder.

The battery question

Both cordless examples are bare tools. The Milwaukee 2738-20 is tool-only on the M18 18V platform; the CRAFTSMAN CMCE100B is bare tool with battery and charger sold separately. The real price of the cordless side is the tool plus a battery you may not own, and no listing here states runtime. If you already own M18 or V20 batteries, cordless is genuinely convenient; if you do not, price the battery before comparing. The corded side has no such question: plug in and polish.

Choose corded if

• You polish near an outlet: garage, driveway, shop.
• You want the most kit for the money: the AUTIWOZ ships pads, sandpaper, towel and brushes.
• You do spot correction and headlights: the 2 and 3 in mini is built for it.
• You want large flat panels cheaply: the 10 in CRAFTSMAN corded covers them.

Choose cordless if

• You move around the car and hate the cord: no outlet, no snag.
• You already own the batteries: M18 for the Milwaukee, V20 for the CRAFTSMAN.
• You want one platform for many tools, with the polisher joining the set.

Buying advice: match the polisher to the panel, the power and the kit

Start with pad size, because it decides how fast a panel goes. The two 10 in orbitals here, the corded CRAFTSMAN CMEE100 and the cordless CRAFTSMAN CMCE100B, cover large panels and hoods in fewer passes. The AUTIWOZ mini works 2 and 3 in pads for curves, headlights and spot correction, and its listing pitches it at small areas; it will do a whole car, but slowly. If you detail full cars, the 10 in pad is the workhorse and the mini is the specialist.

Next, weigh the cord. Corded means unlimited runtime and no battery to buy: the AUTIWOZ runs a 630W pure copper motor with a 12mm orbit that its listing says delivers 37% more power than common 380W models, and the CRAFTSMAN CMEE100 runs 2800 OPM with a variable-speed dial for control. Cordless means freedom of movement at the price of the battery platform: both cordless listings here are bare tools, so the Milwaukee 2738-20 needs M18 batteries and the CRAFTSMAN CMCE100B needs V20 batteries and a charger, all sold separately.

Let your existing batteries vote. If M18 packs already live in your garage, the Milwaukee brushless polisher joins the set with no extra battery cost; if V20 is your platform, the CRAFTSMAN cordless is the natural pick. Buying into a new platform for one tool rarely pays.

Finally, read the kit list before you compare. The AUTIWOZ is the fullest box here: 2 and 3 in backing plates, sponge pads, 3000-grit sandpaper, a wool pad, a microfiber towel, a wrench, spare carbon brushes and a side handle. The corded CRAFTSMAN includes an applicator bonnet and a remover bonnet. The two cordless tools ship as bare tools, so compare them with at least one battery and a charger in the price to keep it honest.

Frequently Asked Questions

Is corded or cordless better for car polishing?

Neither, absolutely. Corded gives unlimited runtime and the fullest kit in this group is corded; cordless gives freedom of movement. Pick by where you polish and which batteries you own.

What size polisher do I need?

The listings span 2 and 3 in minis for details, 7 in as the all-rounder, and 10 in orbitals for large panels. Match the pad to the panel.

Do the cordless polishers include batteries?

No. The Milwaukee 2738-20 and the CRAFTSMAN CMCE100B are both bare tools; batteries and chargers are sold separately.

What does the AUTIWOZ kit include?

Per its listing: 2 and 3 in backing plates, sponge pads, 3000-grit sandpaper, a wool pad, microfiber towel, wrench, spare carbon brushes and a side handle.

Can a mini polisher do a whole car?
