X50 Ultra
A robot that vacuums and mops with spinning pads. Its dock empties the bin, washes the mop and dries it.
Vacuum and mopPrice band: $1,000 to $1,800
Our take
A well-rounded robot for $1,000 to $1,800: 20,000 Pa, a 4.2 cm climb, a body under 9 cm and a dock that does all five jobs we track.
By Emma Walsh
The X50 Ultra doesn’t lead our list on any one measure. It isn’t the strongest robot we have, or the lowest, or the highest climber. What it does is put a 4.2 cm climb, a body under 9 cm and 20,000 Pa in one robot. That suits a house with carpet in one room, a low couch in the next and a raised sill between them.
It vacuums at 20,000 Pa through a pair of brushes that work together. The body is 8.95 cm tall, so measure under the couch, and it gets over a single step of 4.2 cm, where most robots in our list that state a figure stop at about 2 cm. The 6,400 mAh battery is the largest size we list. It’s good for up to 220 minutes. A front camera helps it avoid obstacles.
The mop is spinning pads, and a pad swings out by as much as 4 cm to get under furniture and into corners. What we like most is the choice it gives you on carpet. That’s why the X50 is the best overall pick in our carpet guide. The pads lift 10.5 mm by themselves. If that isn’t enough for your rugs, the robot can leave them at the dock, keep off the carpet altogether, or turn its suction up while it’s there.
The dock takes on all five jobs we track. It sucks the 395 ml bin out into a 3.2-litre bag, washes the pads in 80°C water, dries them, tops up the robot’s water and puts the detergent in. Its own tanks hold 4.5 litres of clean water and 4 litres of dirty.
What it asks for in return is room and money. The dock is 45.7 x 34 x 59 cm and weighs 9.09 kg, so it wants a permanent spot, and the robot adds another 4.53 kg. A full charge takes about 4.5 hours. All of this costs between $1,000 and $1,800, which is a lot to spend if your sills are 2 cm or lower and your furniture sits high.
If you have a sill over 4.2 cm or want more suction, the Mova Z60 Ultra Roller Complete sits in that band too. It brings 28,000 Pa, a 4.8 cm climb and a roller mop, though it’s 9.6 cm tall and its bin is 210 ml. For a mixed house with one awkward doorway, the X50 is where we’d start.
