The models people weigh against each other
Each page puts two or three brands' models side by side from the makers' own figures, marks the blanks, and judges every one against a single house.
Pool robots
-
Aiper vs DolphinAiper Scuba S1 vs. Dolphin Nautilus CC Plus
Aiper Scuba S1 or Dolphin Nautilus CC Plus? Buy the Dolphin Nautilus CC Plus for an inground pool with walls. Both clear the pool on their makers' figures, but more testers back the Dolphin. Pick the Aiper Scuba S1 if you want no cord. The Wybot C1 and S2 are in the table too.
-
Wybot vs AiperWybot vs Aiper: which pool robot should you buy?
Buy the Aiper Scuba S1 for an inground pool up to 50 ft long. It climbs walls, scrubs the waterline and runs 180 min on a charge. The Wybot C1 costs less, at $400, but Wybot only gives a pool area, not a length, so you can't check it against a 35-foot pool.
Litter robots
-
Three brands, two catsLitter-Robot 4 vs PETKIT vs Neakasa: which should you buy?
Buy the Whisker Litter-Robot 4 if you have two or more cats. It is the only one of the three whose maker says how many cats it takes: up to 4. For one cat, get the PETKIT Purobot Max Pro 2. It costs $491, and its drawer lasts the longest, 17 days. PETKIT does not say how many cats it is for, so we do not judge it for two. For a very small or very big cat, or one that will not walk into a drum, get the open-top Neakasa M1 Plus, rated for cats of 2.2 lb to 33 lb. Want to spend less? See our Litter-Robot alternatives.
Robot mowers
-
Luba 3 vs NavimowMammotion Luba 3 vs. Segway Navimow
Mammotion Luba 3 or Segway Navimow? For a quarter-acre yard with a hill and no wire, buy the Segway Navimow i110N. It clears the yard on Segway's own figures for the least money. The Mammotion LUBA 3 AWD 3000H is rated for a lawn several times bigger and a much steeper hill.
