Rank #8 in Best Car Polisher 2026: 10 Ranked, and the Watts That Do Not Add Up
SPTA 7-Inch Rotary Polisher, 1200W, 500-3000 RPM
Price and rating as shown on Amazon when we collected them. Both change.
The SPTA 180mm rotary polisher is a corded machine with a 7-inch backing plate, listed at £95.91 in black and rated 4.5 out of 5 from 315 ratings. It sits at number 8 in this guide, and it is the entry that runs against the pattern we set out at the top: here the big headline number is the one that actually survives a check against the rest of the listing.
The listing states 1200 W of maximum power and, in the same specification block, 5.22 amps at 230 volts. Multiply those two together and you get roughly 1200 W, which is what a mains-fed rotary of this size would draw. Not every number on the page agrees that neatly, though — the speed figures contradict each other, and the rating breakdown does not match the number of ratings. Everything below comes from the Amazon listing as it appears, not from a hands-on test of our own.

Questions people ask
Does the 1200W figure survive a check against the rest of the listing?
Yes. The same specification block gives 5.22 amps at 230 volts, and 5.22 multiplied by 230 comes to about 1200 W, so the headline number and the electrical figures agree with each other on the SPTA 180mm rotary polisher.
What speed does it run at?
The listing gives two different answers. The bullet text describes a 6-setting dial running from 500 to 3000 r/min, while the specification table on the same page states 3300 RPM. The two numbers do not match.
Is the SPTA 180mm rotary polisher corded or cordless?
Corded. The listing gives the power source as corded electric at 230 volts.
What is in the box?
The package bullet lists one 7-inch rotary polisher, three 3-inch, three 5-inch and three 6-inch polishing pads, three wool pads in 5, 6 and 7 inch, four backing plates in 3, 5, 6 and 7 inch, one artificial wool washing glove and two microfibre cleaning cloths. The bullet is cut off mid-sentence after a further quantity, so the full contents are not stated.
What warranty does SPTA offer on this model?
The listing states 24 months warranty on every SPTA tool, with customer service replying within 24 hours during the guaranteed period.
How heavy is it to use?
The listing gives the item weight as 4 kg, and one reviewer describes it as a bit heavy but manageable.
