item delivered internationally 4 days after Singles Day which was very impressive. Packaging was excellent and almost all recyclable. Instructions good and set up easy. It has good clearance under furniture, but take note of the dimensions if you have low furniture - it gets under all my furniture, except one bookcase. It made the transition between wooden floors and carpeted rooms easily. It did get a little tangled in some electric cords and the fringe of a rug, but untangled itself quickly. It ran for around 95 minutes on full charge, plenty of time for my 80 square metre apartment. It did a great job of picking up cat hair. Recommend that you are careful emptying the dust, I spilled a little on the first day, but figured it out now. I'm very happy with it.
We have this model more than a year, we use it often and it works great. This order is a christmas gift for our family.
All OK. recommend.
After The three-day test drive, concluded that this thing in the economy, especially in the presence of the house large dog. Vacuum Cleaner perfectly collects, debris, crumbs, and, which is especially nice, can do so in the absence of host :-) For first acquaintance with кланом robots Vacuum Cleaner Model A4s perfectly suitable (I guess that frustration is: Value for money-функциональнось on five plus). Pleased fast delivery-4 days from Moscow to Rostov-on-Don. Seller and product strongly advise :-) :-) :-)
