The best robotic pool cleaners of 2026

Only if you use it often: for a frame or inflatable pool, a light floor-only robot saves weekly vacuuming, but a manual vacuum is enough for occasional summer use. Check that the manufacturer approves the robot for above-ground pools and soft walls, as heavy wall-climbers can deform the liner. A cordless model avoids running a cable over a high pool edge. For in-ground pools, a robot is far more worthwhile because it also handles walls and the waterline.

Floor, wall and waterline for an in-ground pool, because the greasy ring forms at the waterline; floor-only is enough for small or above-ground pools. A climbing robot also clears algae spots in corners and reduces hand brushing. Floor-only models are lighter and cheaper. Check the maximum depth, the surfaces the robot handles, such as liner, tiles or fibreglass, and how long a full cycle takes.

Cordless suits small to medium pools and easy handling; corded suits large pools and long, thorough cleans. A cordless robot has no tangling cable, but its battery limits cycle length and must be recharged out of the water. A corded robot runs as long as needed and usually climbs walls more strongly. Its power supply must stay at the minimum distance from the pool edge given in the manual, plugged into a GFCI-protected outdoor outlet.

Very little: a 150 W robot running a two-hour cycle uses 0.3 kWh, about 3¢ at an example rate of 10¢ per kWh. Three cycles a week over the pool season add up to only a dollar or two. Your actual rate depends on your province and utility, so check your bill; if you have time-of-use rates, run it overnight to pay even less. The robot has its own filter but doesn't replace the pool's filter pump, which remains the main electricity cost.

Clean it thoroughly, let it dry and store it indoors somewhere frost-free until the pool reopens. Rinse the filter and brushes with fresh water, uncoil and check the cable on corded models, and keep it on its caddy away from direct sunlight. For cordless robots, store the battery at the charge level the manual recommends and top it up every few months. Before spring, check the brushes and tracks for wear.
