Can US bought Homepod be used at 240 volts?

Hmm, that is really odd.

Electrical and Environmental Requirements

• Operating temperature: 0° to 35° C (32° to 95° F)
• Relative humidity: 5% to 90% non-condensing
• Operating altitude: tested up to 3,000 metres (10,000 feet)

No mention of the electrical requirements in a section with the heading Electrical and Environmental Requirements.

HomePod works fine here in the UK, and as you note that information used to be there. I had a quick peek at the WayBack Machine and here is the information that was there as of October 9th 2020.

Electrical and Environmental Requirements

• Built-in power supply
• Line voltage: 100V to 240V AC
• Frequency: 50Hz to 60Hz
• Operating temperature: 32° to 95° F (0° to 35° C)
• Storage temperature: –4° to 113° F (–20° to 45° C)
• Relative humidity: 5% to 90% noncondensing
• Operating altitude: tested up to 10,000 feet (3000 m)
• Maximum storage altitude: 15,000 feet (4500 m)
• Maximum shipping altitude: 35,000 feet (10,500 m)

As far as I know all full-sized HomePods are suitable for the voltage ranges given above, the only difference being the plug fitted in different regions. I can only assume the text has been altered to avoid possible misinterpretation with HomePod mini in case anyone tried to stick 240V up the USB C cord.
