BBE送貨超快,琴晚落單今朝就到!Set好時間每日自動開工,返到屋企就乾乾淨淨,視覺導航好smart唔會亂撞,慳返好多時間。👍

吸塵能力ok,但拖地功能就真係好一般,只係微微濕咗塊地,對頑固污漬冇乜用。預咗呢個價錢唔可以要求太高。

Ah**i 20/11/2024

第一次用掃地機械人,估唔到咁易set up。個App好user-friendly,部機識得自己規劃路線,拖地都幾乾淨,整體滿意。

Da*******g 30/10/2024

Navigates around my dining table and chairs surprisingly well. The anti-collision sensors work great. Doesn't get stuck often. A solid performer.

Alex T. 08/02/2025

App control is the best feature! Set up a no-go zone for my kid's play mat easily. Scheduling is a lifesaver. ✨

Mr. Ng 05/01/2025

Bought this for my dog's shedding. The suction power is impressive. Picks up all the fur easily.

Ke*i 28/12/2024

The Y-shape mopping is good enough for daily maintenance. Keeps the floor feeling fresh.

W. K. Lam 18/02/2025

This price for a 2-in-1 robot is amazing. The CP值 is super high. Does the job well.
