If you’re buying your first vacuum and wondering, “How long will it take to clean my 2000sq-ft flat, and how much battery do I need?” — this guide gives you simple formulas, ready-reckoner tables, and a practical cordless vs corded recommendation for Indian homes. We’ll also show how short on-demand sessions reduce the need for one long cleaning block.

The one-minute formula

Step 1 — Estimate cleaning time
Time (minutes) = Flat area (sq ft) ÷ Cleaning rate (sq ft/min)

Step 2 — Add buffer
Battery minutes required ≈ Time × 1.15 (adds ~15% for turns, furniture, and tank swaps/self-clean)

Pick a realistic cleaning rate

• Quick daily tidy (Eco): 50 sq ft/min
• Standard clean (Auto): 35 sq ft/min
• Deep/Boost zones: 25 sq ft/min

Tip: For wet & dry floor-washers, keep the 15% buffer. If your home has many obstacles, use 20%.

Ready-reckoner (flat size → time → battery)

Assumes a standard pass at 35 sq ft/min. Buffer already included.

Flat size (sq ft)	Approx time (min)	Battery minutes to budget
600	~17–19	20–22
800	~23–24	26–28
1,000	~29–30	33–35
1,200	~34–37	40–43
1,550 (≈144 m²)	~44–51	51–59
1,800	~51–58	60–67

If you plan lots of Boost or have rugs/pet zones, plan those areas at ~25 sq ft/min and add them separately.

Examples you can copy

1) 1,000 sq ft, quick daily tidy

Rate = 50 sq ft/min → Time = 1,000 ÷ 50 = 20 min
Battery ≈ 20 × 1.15 = 23 min

2) 1,200 sq ft, standard clean

Rate = 35 sq ft/min → Time = 1,200 ÷ 35 = 34.3 min
Battery ≈ 34.3 × 1.15 ≈ 40 min

3) 1,550 sq ft (≈144 m²), mixed clean

1,300 sq ft at 35 → 1,300/35 = 37 min
250 sq ft Boost zones at 25 → 250/25 = 10 min
Total time = 47 min → Battery ≈ 47 × 1.15 = 54 min

Cordless vs corded — which should I choose?

Cordless (daily convenience)

• Best at: 2–4 short sessions (3–15 min) through the day — kitchen after meals, hallway dust, pet hair.
• Battery planning: Use the table above. If your standard clean is 40–60 minutes, split into zones or consider a spare battery (if supported).
• Why it’s easier: You won’t “save mess for later.” Short on-demand sessions keep floors consistently clean and reduce the need for one long block.

Corded (unlimited runtime)

• Best at: Single, longer sessions (e.g., weekly deep clean) with stable suction and no runtime limit.
• Reach: A 5–6 m cable typically covers most rooms from a nearby plug; re-plugging is minimal in many Indian flats.
• Good pairing: Use corded for deep cleans; cordless for quick daily maintenance.

Quick chooser for common flat sizes

• ≤ 1,000 sq ft: Cordless is enough for a single pass (Eco/Auto) or two short sessions.
• 1,001–1,500 sq ft: Cordless (zonal/on-demand) or corded (single session). Choose based on your routine.
• ≥ 1,500 sq ft: Corded for the weekly deep clean; cordless for daily upkeep.

FAQ

Q. Can a cordless clean my whole 1,500+ sq ft flat in one go?
A. Yes if the battery spec meets your calculated need (~50–60 minutes). Many families prefer splitting into 2–3 short sessions or pairing with a corded unit for the weekly deep clean.

Q. How do wet & dry floor-washers affect timing?
A. They add small pauses for tank swaps and a brief self-clean — the 15% buffer in our formula covers this for most homes.

Q. What about Boost mode for rugs/pet corners?
A. Estimate those areas separately at ~25 sq ft/min, add to your total, then apply the 15% buffer.

Q. Which is easier for house help?
A. Cordless for quick, low-effort sessions; corded for longer passes with stable power. Most helpers adapt quickly to both.
