- Japan is Bic Camera.com's product page '[Genuine Domestic Product] Robot Vacuum Roomba Plus 405 Combo Robot + AutoWash Charging Station G185060 (online-store-exclusive),' ¥98,800 incl. tax; iRobot's official Rakuten Ichiba store page for the same item was priced at ¥99,706 as of 2026-09-12. Correction note: this entry originally recorded ¥45,800 (sourced as 'Rakuten Ichiba product page price,' taken from iRobot's official Rakuten store page); reopening that page on 2026-09-12 could not reproduce that figure, and it was roughly half the Japan chain/official price, so it was judged a misread and replaced with the chain retailer's product page price. Taiwan is momo's own store '[iRobot] New Roomba Plus 405 Combo All-in-One Vacuum-Mop Robot (Dust Collection, Pad Washing, Self-Drying, Dual Spinning Mops, 70x Suction),' i_code 13873753, listed at NT$12,999 (re-verified 2026-09-12). Both sides are the same Roomba Plus 405 Combo + AutoWash charging dock, matching model G185060; Taiwan's price here is a retailer promotional price, and the gap from Japan's official pricing is very large — please check the page as of your purchase date before buying.
