Roca is one of the world's largest manufacturers of sanitary ware, with 78 factories worldwide and operations in more than 50 countries.

Roca has done quite successfully in localization in China, in 2006 the acquisition of Eagle brand sanitary ware, the current ceramic sanitary ware is mostly produced by its OEM, and then also acquired Jishiduo Sanitary Ware, half of the sales in China from high-end hotels, high-end commercial housing decoration, etc.

Almost all Roca products use better quality urea-formaldehyde covers, with a water efficiency rating of more than 2, Vortex and IN-TANK technology, Vortex whirlpool flush, and IN-TANK is similar to other brands of rimless toilet technology, which guarantees the flushing performance of the toilet. However, the Roca toilet uses the original water parts, which is slightly inferior to the water parts used by other international first-line brands, such as Geberit and Vidia.

Roca smart toilets mainly have three product lines: Georgia, Impera and Adis, which represent the high, medium and low grades of Lejia products.

If the budget is around 10,000 yuan, the Impera series is a good choice. Equipped with Vortex and IN-TANK technology, the Impera E has a water efficiency rating of 1, and is also equipped with a multi-level adjustable cleaning mode, with a night light and an automatic flip function, the overall function is more comprehensive.

If you are a user who pursues cost-effectiveness, you can consider the Ardis series smart toilet, which is priced at about 5000 yuan, but the inner wall of the toilet adopts a circle hole design, and is not equipped with edgeless IN-TANK technology, the flushing effect is relatively poor, and it may be troublesome to clean up later.

As for the high-end Georgia series, the price has reached 20,000 yuan, but its basic functions are the same as the Impera series, and the cost performance is not high.
