Best cheap robot vacuums

Start with the Eufy RoboVac 11s. It's the classic cheap robot vacuum: simple, quiet, no app fuss, and it handles everyday dust and pet hair on hard floors and low-pile carpet. It bumps around rather than mapping, so it's best in one open room at a time.

Who the others suit:

• iRobot Roomba Combo Essential — you want a cheap one that also damp-mops, with a long run time.
• Lefant M210 Pro — the smallest spend for a slim, low-clearance vacuum.
• TP-Link Tapo RV30 Max Plus — you'd rather pay more once for LiDAR mapping and self-emptying.
• Shark Navigator with Self-Empty Base — a mid-priced step up with a base that holds weeks of dirt.

Skip the premium models here unless you want mopping and auto-wash docks.
