Best budget robot vacuums for 2025 — what to buy under $300

Robot vacuums have become far more affordable: you can get a competent model for around $300 that handles daily floor cleaning and saves time. These budget bots won’t match premium models for suction, capacity or self‑emptying features, but many deliver reliable 40–60 minute runs, effective pickup on hard floors and decent carpet performance at lowered settings.

When shopping, pay attention to a few practical specs rather than marketing jargon. Below are the core features to prioritize and trade‑offs to expect when choosing a budget model.

What to look for

• Suction: If the maker lists a Pascal (Pa) number, ~2000Pa is a good target for carpets; otherwise look for models that advertise a “max” or boosted mode.
• Run time: 40–60 minutes is common at this price; make sure it returns to dock reliably to recharge.
• Brush design: Tangle‑resistant or combo brush rolls are better for pet hair; check if side brushes are replaceable.
• Bin capacity: Larger dustbins mean less frequent emptying—important if you have pets.
• Navigation & control: App control and mapping are rare at the lowest prices but worth seeking if you want scheduling and no‑go zones; remotes can cover basics.
• Sensors: Obstacle detection and cliff sensors are musts to avoid bumps and falls.

Trade-offs on budget models

Expect more plastic in the chassis, thicker/heavier builds, and fewer premium features like self‑emptying bases or advanced dirt sensors. Some cheap models lack Wi‑Fi, so they won’t support app scheduling or voice assistants—but they can still be useful with a remote control.

Maintenance tips

• Empty the dustbin after each run when possible, or at least regularly to avoid performance loss.
• Check and clean brushes and remove hair from the main roller and side brushes weekly if you have pets.
• Replace filters according to the manufacturer (often every 1–3 months) to maintain suction and air quality.
• Wash mop pads and water tanks for combo models to prevent odors.
