Winter leaves its signature on paint: swirl marks under the garage lights, water spots on the hood, a wax job that gave up in February. A cordless polisher turns that Saturday around without dragging a cord across the driveway. The best cordless polisher under 80 is a 6-inch class tool with enough speed range for both waxing and defect removal, a battery plan that fits your garage, and pads in the box. This guide compares five cordless polishers on what each listing states: speed range, batteries, pads, warranty and whether the battery is even included. Two are bare tools for owners who already hold the batteries; three are full kits.

Buying guide: best cordless polisher under 80
Speed range: what the numbers mean
Speed is the main spec here, and the range is wide: up to 3000 rpm on the WORKPRO, 2500 to 5500 on the Alrigon 5500, 2800 to 5500 on the Protmex, up to 6000 on the L1NXIXI, and 750 to 6800 on the Alrigon 6800. The Alrigon listing gives the clearest speed map: low speed for waxing and buffing, medium for polishing and cleaning, high for removing paint defects and oxidation. The WORKPRO lists five speeds up to a stated 3000 rpm with a plus-minus 10 percent tolerance and an LED indicator for the selected setting. More speeds give finer control; the widest stated range here belongs to the Alrigon 6800.
Batteries: full kits vs bare tools
Three listings include batteries and two do not, and that split decides the real contents of the box. The Protmex includes two 21V 2000mAh batteries, the L1NXIXI includes two 2000mAh batteries with a charger, and the WORKPRO includes one 2.0Ah battery with a 1-hour fast charger and a battery status indicator. Both Alrigon models are tool-only and state compatibility with Dewalt 20V max batteries, naming packs like the DCB206, DCB205 and DCB204; the battery is not included. The L1NXIXI listing states its tool is incompatible with Dewalt batteries but compatible with the Makita 18V battery system. Buy the kit if you own no batteries in that system; buy the bare tool if your shelf already holds them.
Pads and attachments in the box
Pad count varies more than pad size: four of the five are 6-inch tools, while the WORKPRO’s pad size is not stated. The Protmex ships 18 attachments: sponge pads, wave sponge pads, wool discs, cloth covers and sandpapers. The Alrigon 5500 ships 3 sponge pads, 7 buffer pads, 2 wool pads, 4 sandpapers and a towel. The L1NXIXI ships sponge pads, wave sponge pads, a wool pad and a towel. The WORKPRO kit adds a side handle, two backing pads and a carrying bag. The Alrigon 6800’s spec table lists only a bar tool, so its pad counts are not stated. Count the pads against the jobs you plan: a wax job wants clean foam, defect removal wants wool and sandpapers.
Warranty and the fine print
Two listings state a warranty term and three do not. The Protmex spec table lists a 2-year warranty, and the Alrigon 5500 lists 1 year. The WORKPRO, Alrigon 6800 and L1NXIXI state no warranty term. Read the protective features too: the Protmex lists safe temperature control protection, and the WORKPRO lists overheat protection that stops the tool after 6 to 7 minutes on the high-speed setting, which the listing calls normal, plus overload protection on the charger. Neither is a safety certification, but both are stated behaviors worth knowing before the first job.
Weight and handling
Polishers live in your hands, so stated weight matters. The WORKPRO is the lightest stated figure here at 1.94 lb including the battery, which suits overhead and vertical panels. The L1NXIXI spec table lists 4.29 lb and the Alrigon 6800 lists 1.62 kg. The Protmex listing states no weight, and the Alrigon 5500’s spec-table figure of 0.02 kg reads like a placeholder. On grip, the WORKPRO lists a rubberized handle plus a side handle in the kit, and its spindle lock speeds pad changes. Where a listing gives no handle detail, plan on two-handed work for larger panels.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Frequently Asked Questions
Do these polishers come with batteries?
Three do and two do not. The Protmex includes two 21V 2000mAh batteries, the L1NXIXI includes two 2000mAh batteries with a charger, and the WORKPRO includes one 2.0Ah battery with a 1-hour fast charger. Both Alrigon models are tool-only: they state compatibility with Dewalt 20V max batteries, and the battery is not included.
Can I use my Dewalt 20V batteries?
On the two Alrigon models, yes: both state compatibility with Dewalt 20V max batteries and name packs including the DCB206, DCB205 and DCB204. The L1NXIXI listing states its tool is incompatible with Dewalt batteries, though it states compatibility with the Makita 18V battery system.
What speed should I use for waxing?
Follow the Alrigon listing’s speed map: low speed for waxing and buffing, medium speed for polishing and cleaning, and high speed for removing paint defects and oxidation. Start low and step up only as the job needs it.
Why does the WORKPRO stop on the high setting?
That is the overheat protection the listing describes: after 6 to 7 minutes on the high-speed setting, the tool stops automatically. The listing calls this a normal protective feature, not a malfunction. Let it cool, then continue at a lower setting.
What is the difference between the two Alrigon models?
Speed range, display and warranty. The Alrigon 6800 spans 750 to 6800 rpm with an LCD display showing the speed level and battery capacity, and states no warranty. The Alrigon 5500 spans 2500 to 5500 rpm with no display stated, and lists a 1-year warranty. Both are 6-inch, brushless, tool-only models for Dewalt 20V max batteries.
Which polisher is the lightest?
Of the stated weights, the WORKPRO at 1.94 lb including the battery is the lightest. The L1NXIXI spec table lists 4.29 lb and the Alrigon 6800 lists 1.62 kg; the Protmex listing states no weight.
