You're about to spend a few hundred pounds on a robot vacuum. Before you do, it's worth knowing the realistic running costs — not just the upfront price — so there are no surprises six months in.

Electricity: Genuinely Negligible

A robot vacuum's charging dock draws very little power — typically under 50p a month even with daily cleaning runs. This is by far the smallest ongoing cost and not something to factor heavily into your decision.

The Real Ongoing Costs

• Replacement filters — typically every 2–3 months, usually £5–£10 per pack
• Side brushes — every 3–6 months depending on use, around £5–£8 per pair
• Main brushroll — every 6–12 months, typically £10–£20
• Self-emptying dock bags (if applicable) — around £5–£10 for a pack, lasting several months
• Mop pads (if applicable) — a few pounds, occasionally replaced or just washed

Realistically, budget around £30–£60 a year in consumables for most models — modest against the time saved.

Self-Emptying Docks: Worth the Extra Cost?

A self-emptying dock adds to the upfront price but removes the most common daily friction point — manually emptying the bin after every run. For most buyers genuinely worth it for the convenience alone, even accounting for the cost of replacement bags.

The Honest Verdict

Total cost of ownership for a robot vacuum is genuinely low compared to the time it saves. Electricity is negligible, and consumables are a modest, predictable annual cost — nothing that should put you off buying.
