Drying Space: Check the total drying space the airer offers. A 4-arm rotary airer typically provides ample space, ranging from 40 meters to over 60 meters of drying line.
Adjustability: Look for models with adjustable height settings to accommodate different laundry types and user preferences.
Material and Durability: Choose a rotary airer made from durable materials like aluminum or steel, which are weather-resistant and rustproof.
Ease of Installation: Consider how easy it is to install. Some models come with a ground spike for secure installation, while others may have a concrete base.
