We were hesitant to purchase because of cost but went ahead because of good sale offer. Have been pleased with the product’s performance. Good upgrade from our V6 that was getting a tired battery. Gen5 much heavier duty machine and good battery life. The auto detect feature seems to work well and are able to do most of our 1700 square feet of carpet and hard floor. Initially thought the laser light on the fluffy head would be more of a gimmick than anything but find it effective and kind of satisfying in seeing all that debris in a ‘there it is and now it’s gone’ way. Only reservation would be the trade off between bigger and more powerful meaning heavier and less able to get in the tight spaces as easily with crevice tool and dust brush.  Might re-battery the V6 and keep on hand for the off floor work.
