Best Investment Ever! A Vac-Mop!!!
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
These are replacement tools that fit our multipurpose vac/mop. This product is the most helpful and productive item we own. My daughter and I are free to do other things while Miss “B” is busy cleaning our floors! Such a backsaver! The floors are cleaner than manually sweeping and mopping them ourselves! It doesn’t get any better than that!

This is a Yes!
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
I needed to change out my Dreame vacuum accessories but didn’t want to pay the huge amount for the name brand kit, this works beautifully and fit perfectly. I cannot tell a difference and it lasts just as long as the original!

Good fit and quality - careless packaging
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
OK - I'm happy with most of the kit. The dead corner brushes are crammed into small bag and bent out of shape. It looks like 2 of the 6 in the kit I received might be usable. Since I can get 3 of these for the cost of the OEM kit, I suppose I'm still ahead of the game, but it would be nice if a little more care was taken in the packaging.
